JP2014-129075A

  In the technique disclosed in Patent Document 1, a large number of setting items exist, the screen is appropriately switched to find a desired setting item, and the setting content is changed. Such processing is complicated, and there is a problem that smooth setting cannot be performed.

  The object of the invention of the present application is not limited to this, and there is an intention to acquire the right by a divisional application, amendment, etc. for a configuration aiming to obtain an effect obtained from the configuration portion disclosed in the present specification and drawings. . For example, in the present specification, a subject is disclosed in which a part described as “can be” is read as “a subject is a subject” in the present specification. The issues are described as being independent of each other, and the organization for solving the issues is also willing to acquire the right by divisional application / correction etc. alone. Even if the problem is implicitly grasped from the description of the specification, the applicant intends to make a part of the configuration described in the present specification as a claim in the amendment or divisional application. Moreover, the subject which combined these independent subjects is also disclosed.

  (1) A system having a notification function for a user and a setting function for setting items related to notification by the notification function. A menu screen is displayed, and when a predetermined item on the first menu screen is selected, a second menu screen for the setting without immediacy is displayed, and the first menu screen immediately An item which can be set and an item which goes to the second menu screen are provided.

  By operating the screen displayed at the normal time, the first menu screen having the immediacy is displayed, so that the user can immediately select an item to be performed at that time. When a predetermined item is selected from the first menu screen, the second menu screen is displayed, so that the user can set items related to the desired notification while operating the second menu screen.

  The system may be, for example, a vehicle that can be mounted on a vehicle. If the system can be mounted on a vehicle, the notification may provide information useful for driving and traveling. The system may be configured of a plurality of devices and devices, but may be configured of one device. The screen displayed at normal time is, for example, a screen displayed during operation.

  (2) When the first menu screen is displayed for a predetermined time, the original screen may be restored, and even if the second menu screen is displayed for a predetermined time, the original screen may not be restored. By looking at the first menu screen, the user can immediately determine whether there is an immediate item that he / she wants to process. If there is no item, the user can return to the standby screen automatically if left alone. Because it is good. The second menu screen may consider how to set the items while looking at the display contents of the display unit, and there may be no operation for a predetermined time or more. In such a case, when the original screen is restored, it is necessary to perform an operation for transitioning to the screen for processing again, which is complicated. Therefore, it is preferable that the automatic return can be performed slowly and the operation can be surely performed.

  (3) The first menu screen having immediacy displays all selectable items in one screen, and the second menu screen for setting without immediacy is an item to be displayed on one screen. It is good to limit the number of display to the standard value or less.

  Since the items that can be selected on the first menu screen are displayed in a list on the first menu screen that has immediacy, the user can immediately select a target item and perform desired processing. Since the second menu screen has a limited number of displays in one screen, the items for setting displayed on the second menu screen are easy to see, it is easy to find the desired item to be set, and the purpose is surely Items can be selected. By limiting the number of displays, the number of second menu screens increases, but because there is no immediacy, it is possible to search slowly. In particular, when the selection of the setting item is a touch type on the display screen, the number of displays is limited. For example, the area of one setting item is enlarged or the distance between adjacent setting items is increased. There is no need to erroneously touch different items or simultaneously press a plurality of adjacent setting items, which improves operability.

  (4) The second menu screen for setting without immediacy arranges a predetermined number of setting items vertically and displays the title of the setting item and the current setting content in the display area of the setting item. It is good to have a function. Although selectable setting items are displayed on the second menu screen, it is possible to know the current setting contents of the setting items displayed together with the title of the setting item. Since the user does not have to enter the layer for setting the setting value of the setting item in order to confirm the current setting contents, the operability is preferably improved.

  (5) The second menu screen for setting without immediacy arranges a predetermined number of setting items vertically and displays the title of the setting item and the current setting content in the display area of the setting item. When there is a function, an operation on the display area, a function to display a setting menu screen for changing the setting contents of the setting item, and an operation on the area to display the current setting contents in the second menu screen When performed, it is preferable to have a function of switching the current setting contents without displaying the setting menu screen. In this way, setting contents of setting items may be set without transition to the setting menu screen of a lower hierarchy. The function of switching the current setting contents without displaying the setting menu screen is preferably applied when the number of setting contents candidates is small, and when the number of candidates is large, the function of switching is preferably disabled. The small number may be two to three, and more preferably two.

  (6) The second menu screen for setting without immediacy is a menu screen including a setting item title and a setting item display area for displaying the current setting contents, and the menu screen is different from the menu screen. A setting menu screen for changing the setting contents of the setting item, and display words / phrases of the setting contents to be displayed on the menu screen and display words of setting contents to be displayed as selection candidates to be displayed on the setting menu screen It is preferable that each of the display words meaning the same contents have a simpler expression on the menu screen.

  On the menu screen, the current setting contents can be displayed in the setting item display area, and the user can understand the contents without hesitation. In the state of transition to the actual setting menu screen, the setting contents as selection candidates are correctly displayed, so that the user can correctly understand the contents. The simple expression may be, for example, a mark / symbol, but may be a term with a small number of characters, and a short form when the number of characters is small.

  (7) A function that performs processing for the setting of the setting item when a first operation is performed on the setting item displayed on the second menu screen, and a second that is different from the first operation. It is preferable to have a function of displaying an explanatory screen of the setting item when there is an operation of.

  The user can set the content of the setting item such as change by performing the first operation, and can display the explanation screen and know the content of the setting item by performing the second operation. For example, the user can know the contents of the setting items smoothly and in a timely manner without looking at the instruction manual, and can immediately determine whether or not the item is necessary for the user. It can be set to the notification content.

  The first operation may be a short press, for example, and the second operation may be a long press, for example. The function for performing processing for setting may be, for example, display of a setting menu screen for changing the setting of the selected setting item, or changing the setting content of the setting item without changing the menu screen. The explanation screen may be, for example, an explanation pop-up screen.

  (8) A function that performs processing for the setting of the setting item when a first operation is performed on the setting item displayed on the second menu screen, and a second that is different from the first operation. A function to display an explanation screen of the setting item when the operation is performed, and the explanation screen is displayed even if the second operation is performed on the screen displayed in the normal state and the first menu screen. It is good not to display.

  Since the screen that is normally displayed is a screen that is always displayed, there is no need for explanation on the explanation screen. For example, the explanation screen is displayed when the user performs a second operation different from the first operation unintentionally. In this case, it is troublesome, but it is only necessary to eliminate the troublesomeness by not displaying. Since the first menu screen is a screen for selecting a process having immediacy, the contents of each process are easy to understand and there is no need for explanation on the explanation screen. For example, the first menu screen is different from the first operation unintentionally. If the explanation screen is displayed when the second operation is performed, it is cumbersome, and it is only necessary to eliminate the complexity by not displaying the explanation screen. In particular, for example, when the first operation is a short press on the screen and the second operation is a long press on the screen, the first menu screen is a screen for performing processing having immediacy. Since the screen may continue to be pressed too quickly, it is troublesome to display the explanation screen by long pressing, and it is preferable to set it not to display because it impedes immediate processing.

  (9) The notification function has a first alarm by CG with motion and a second alarm using an image corresponding to a scene including the alarm target, and after displaying the first alarm at a predetermined timing, the second alarm It is preferable to have a function of displaying an alarm.

  Since the image corresponding to the scenery including the alarm target by the second alarm is displayed after the user is alerted by the moving CG, the alarm content may be easily recognized by the user. The second alarm performed after the first alarm may be issued continuously. Continuing alarms increases the continuity of the first alarm CG and the second alarm image, so it is possible to effectively perform alerting and recognition of alarm content by continuous image playback. . The area for displaying the CG of the first alarm and the area for displaying the image of the second alarm may be performed at the same position. By displaying the first alarm and the second alarm at the same position, the integration and continuous continuity of both may be enhanced. The CG based on the first alarm may be related to the type of alarm. The image of the second alarm is preferably an image viewed from the driver's seat, and more preferably a photographed image. The alarm target may be a specific device / equipment, and may be a specific location in the case where there is no such device, but it may be easy to understand if it is a specific device / equipment.

  (10) The notification function includes a first alarm by a moving CG and a second alarm using an image corresponding to a scene including the alarm target, and after displaying the first alarm at a predetermined timing, A function for displaying an alarm is provided, and the first alarm is preferably reproduced by repeating the movement a plurality of times.

  If the image of the second alarm is continuously displayed after the first alarm, it will be difficult to receive attention, but it will be noted by taking a certain amount of time to display the CG with the movement of the first alarm and repeating a series of movements several times. It becomes easy to do. Since the motion is replayed a plurality of times, the first alarm by CG may be noted. For example, if the CG is related to the type of alarm target, the type of alarm target can be recognized by the first alarm, and then the actual situation can be displayed by displaying an image corresponding to the scenery including the alarm target. It is preferable because it can be understood.

  (11) The notification function has a first alarm by a moving CG and a second alarm using an image corresponding to a scene including the alarm target, and after displaying the first alarm at a predetermined timing, A function for displaying an alarm is provided, and after the first alarm is displayed, the process for displaying the second alarm may be repeated a plurality of times.

  For example, when the second alarm is continuously displayed after the first alarm, the display time of the second alarm becomes longer and the degree of attention to the first alarm displayed first decreases. By displaying the first alarm consisting of moving CG after the first alarm, the first alarm may be noticed as well. In particular, when the image marked by the second alarm is a still image, it is difficult to be noticed if the image without motion is continuously displayed, but by appropriately displaying the first alarm consisting of CG with motion, It may be possible to cause movement in the peripheral vision of the user and recognize that there is a target to be careful.

  The display time of the first alarm may be, for example, several seconds. If there is such a time, the movement can be recognized, and when the user looks at the screen along with the recognition, a second alarm image such as a live action is displayed if the user waits for a few seconds at the longest. It is good because the contents of the second alarm can be confirmed without watching for a long time.

  If the first alarm is a CG corresponding to the type of the alarm target, the CG corresponding to the type is notified after the actual landscape image is displayed, so that the CG is also noticed and displayed in the second alarm. It is good because it deepens the understanding of the type of alarm target. In particular, when a warning screen is displayed even when the voice is not sounding when approaching, by inserting a CG with appropriate movement, movement should be generated in the peripheral vision of the user, and attention should be paid Recognize that there is an alarm target. If you look at the screen, you can see the second alarm image if you wait a few seconds at the longest.

  A plurality of repetitions is not necessarily limited to an integer, and may be terminated at the first alarm as, for example, 2.5 times, or may be stopped in the middle of the first alarm or the second alarm Is an integer.

  (12) The notification function has a first alarm by a moving CG and a second alarm using an image corresponding to a scene including the alarm target, and after displaying the first alarm at a predetermined timing, It is preferable that the CG has a function of displaying an alarm, and the CG has a movement to zoom in on an alarm target, and displays the image according to the second alarm next to the zoomed-in image. The user can be made to recognize what the alarm target is by the first alarm, and then the second alarm can be given to notify the presence of the recognized alarm object.

  (13) The notification function is preferably provided with a function of displaying a control information screen, and the type of control information notified on the control information screen is notified in a predetermined color. Since the control information is displayed on the control information screen and the type of the control information is notified by color, the user can understand at a glance what the control information is notified by looking at the color. . The control information includes, for example, public control information, information on speed control guidelines, and the like, and these types are distinguished by color. For example, it is difficult to find the type of the control information when displayed in text, but it can be understood at a glance by distinguishing it by color. The predetermined color may be displayed at a predetermined position in the control information screen as in the embodiment, for example. For example, the predetermined color may be displayed on the LED light emitting unit of the embodiment. However, when the predetermined color is displayed in the control information screen, the relationship with the displayed control information may be easily understood.

  (14) The notification function may include a function of displaying a predetermined screen after displaying the control information screen for a predetermined time, and a function of displaying the control information screen when a predetermined place on the predetermined screen is operated. . Even if the control information screen disappears and the content is overlooked, it can be redisplayed by a simple operation and the content can be confirmed. The predetermined screen may be an original screen before the control information screen is displayed. For example, the predetermined screen may be a map display standby screen.

  (15) The notification function includes a function of displaying a predetermined screen after displaying the control information screen for a predetermined time, and a function of displaying the control information screen when a predetermined place on the predetermined screen is operated. If there is no control information in the middle road, the control information screen may not be displayed even if the predetermined place is operated. When the running road is not related to the control information, the control information screen is not displayed, and it is only necessary to easily know whether or not the control information exists by operating a predetermined place.

  (16) An alarm target that is the same type of alarm target and requires attention for passage may be a specific alarm target, and the notification function may loosen a condition that the specific alarm target is a notification target. Even if it is the same type of alarm target, since the condition to be a notification target is relaxed for a specific alarm target, it becomes easier to be notified and the notification is made at a relatively distant position from the alarm target. Therefore, it can be understood that it is necessary to carefully advance or detour from a distant position, and safe and smooth driving can be performed. The same kind of alarm target may include the same part in the name, for example, "crossing" and "cross over". To loosen the condition to be a notification target is, for example, to increase the separation distance to be the target or to widen the angle included in the notification target. The notification of the specific alarm target may be an alarm mode that is more prominent than the notification of the normal alarm target.

  (17) The notification function may display a message window that displays information related to an alarm target so as to overlap the map screen, and the overlapping position may be a place where it is difficult for the vehicle to travel. Since the message window is displayed superimposed on the map screen when displaying the message window, the same map screen may be used regardless of whether or not the message window is displayed, for example. It is preferable that a standby screen such as a map screen can be displayed on the entire screen. Since the map information that cannot be seen by overlapping in the message window is a place where it is difficult for the vehicle to travel, there may be less harmful effects. The display position of the message window should be fixed. The place where it is difficult to get ahead is better at the right edge of the screen. The message window should not be displayed at all times, but should be displayed when necessary. For example, when two windows are displayed across the vehicle at the current position, the windows do not overlap and information about the same alarm target is displayed. It is good to display

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. These drawings are used to explain the technical features that can be adopted by the present invention. The configuration, shape, and the like of the device described are merely illustrative examples, and the present invention is not construed as being limited thereto, and is based on the knowledge of those skilled in the art without departing from the scope of the present invention. , Various changes, modifications, improvements can be made.

[Basic system configuration]
FIG. 1 and FIG. 2 show the configuration of a radar detector as one form of a vehicle-mountable device which is a preferred embodiment as a system constituting the system of the present invention. The radar detector 1 includes a thin rectangular case 2 and is fixed to a vehicle dashboard or the like by using, for example, a bracket 3 attached to the lower side of the back side of the case 2.

  A display unit 4 is provided on the front surface of the case 2. The display unit 4 is configured of a color liquid crystal display. This color liquid crystal display uses, for example, a 3.5 inch size. The display unit 4 includes a touch panel 5 that detects which part of the display unit 4 is touched. An LED light emitting unit 6 and an illuminance sensor 7 are arranged on the left side of the front surface of the case 2. The LED light emitting unit 6 has a rod-like light emitting area extending in the vertical direction, and functions to emit various colors. For example, a full color LED may be used. The LED light emitting unit 6 emits a warning in various colors, for example, according to a notification such as the type of alarm, the degree of urgency, and public control information. The illuminance sensor 7 is disposed on the upper side of the LED light emitting unit 6 and detects ambient brightness. Based on the ambient brightness detection result output from the illuminance sensor 7, the control unit 18 adjusts the luminance of the display unit 4.

  The right side surface of the case 2 is provided with a card insertion slot 9 for mounting a memory card 11 as a detachable recording medium. A card reader 10 is built inside the card insertion slot 9 in the case 2. By inserting the memory card 11 from the card insertion slot 9, the memory card 11 is attached to the card reader 10. The card reader 10 internally takes in data stored in the mounted memory card 11. The data stored in the memory card 11 includes update information such as new alarm target information (position information such as latitude and longitude, type information, and the like). The update information is stored and downloaded in a database 19 built in the apparatus via the control unit 18, for example, and the data is updated.

  The database 19 can be realized by a non-volatile memory (for example, a NAND Flash memory) internally or externally connected to the microcomputer of the control unit 18. Further, the memory card 11 itself may be configured as a part or all of the database 19. The database 19 stores map data and information related to a certain alarm target at the time of shipment, and data and the like regarding the alarm target added thereafter are updated as described above.

  The GPS receiver 13 is disposed inside the rear side upper side of the case 2 and the microwave receiver 14 and the wireless receiver 15 are disposed beside the GPS receiver 13. The GPS receiver 13 receives a radio wave transmitted from an artificial satellite on the satellite orbit and outputs current position information obtained by positioning the latitude and longitude of the current position. In addition to the positioning function based on the radio wave from the artificial satellite, the GPS receiver 13 receives a signal from the quasi-zenith satellite "MICHIBIKI" and performs a more accurate positioning, such as the Russian navigation system, Gronas (Global Navigation Satellite System). The function of calculating the current position on the ground using satellites, and receiving signals from the sunflower of the multipurpose satellite for transportation, the error of the current position to be measured by receiving the radio wave of the artificial shell in the satellite orbit Functions to correct and improve positioning accuracy, functions to support Indian satellite-based satellite navigation augmentation systems such as GAGAN (GPS Aided GEO Augmented Navigation), EU (European Union) global navigation such as GALILEO (Global Navigation Satellite System) It is good to have a function corresponding to a satellite system. The microwave receiver 14 receives a microwave having a predetermined frequency emitted from the velocity measuring device. The wireless receiver 15 receives VHF and UHF band radio waves and the like for traffic control communication. A speaker 16 is incorporated at a predetermined position in the case 2.

  A DC jack 12 is disposed below the back side of the case 2. The DC jack 12 is used to supply power to the radar detector 1. For example, a connector 22 of a cigar plug cord can be connected to the DC jack 12, and the cigar plug cord can be connected to a cigar socket of a vehicle to receive power supply. Instead of the cigar plug cord, an OBDII adapter 21 that can be connected to an OBDII connector of the vehicle is preferably used. The OBDII connector is also referred to as a failure diagnosis connector, is connected to the ECU of the vehicle, and periodically outputs various types of vehicle information. Therefore, the OBDII adapter 21 and the OBDII connector on the vehicle body side are connected, and the connector 23 attached to the tip of the connection cord of the OBDII adapter 21 is connected to the DC jack 12 to supply power to the radar detector 1. At the same time, the control unit 18 periodically acquires various types of vehicle information.

  The vehicle information includes information on the travel distance of the vehicle, the vehicle speed of the vehicle, the injection injection time, the intake air amount, the remaining fuel, and the like. The remaining fuel is the amount of fuel remaining in the current fuel tank and is output with a resolution of 0.5 liters. Therefore, by acquiring the remaining fuel periodically and recording the timing of the change between the previous remaining fuel and the current remaining fuel, it is consumed after the previous change occurs until the current change occurs. Fuel can be said to be 0.5 liter. In addition, there are also cases in which information on fuel consumption (information on lifetime fuel consumption, current fuel consumption, instantaneous fuel consumption, etc.) is output periodically. The control unit 18 displays the acquired vehicle information on the standby screen, acquires velocity information even in a place where satellite information can not be received, such as in a tunnel, and performs more accurate warning.

  The case 2 is provided with an acceleration sensor 25, a gyro sensor 26, and an atmospheric pressure sensor 27. The acceleration sensor 25 detects acceleration relating to the vehicle, and obtains acceleration in two directions, the front-rear direction and the lateral direction of the vehicle. The gyro sensor 26 integrates the angular velocity so that the control unit 18 obtains the traveling direction of the host vehicle on the map. The atmospheric pressure sensor 27 is used to measure a change in altitude due to a change in atmospheric pressure.

  The control unit 18 is a microcomputer including a CPU, a ROM, a RAM, a non-volatile memory, an I / O and the like, and is connected to the above-described units as shown in FIG. The control unit 18 receives information input from the various input devices (touch panel 5, GPS receiver 13, microwave receiver 14, wireless receiver 15, acceleration sensor 25, gyro sensor 26, pressure sensor 27, etc.). Based on the information to be notified to the driver is created, the information is output using an output device (display unit 4, LED light emitting unit 6, speaker 16 or the like).

  The functions of the radar detector 1 of the present embodiment are stored in the NAND Flash memory of the control unit 18 as firmware executed by the CPU of the control unit 18 and are implemented by execution by the CPU of the control unit 18. The firmware stored in the NAND Flash memory can be updated by new firmware stored in the memory card 11.

“Basic functions for notification and alarm using display unit 4”
The main information output from the output device of the radar detector 1 is alarm information for urging the driver to be safe. The alarm information is output in the following cases, for example. The control unit 18 obtains the distance between the alarm target position (latitude and longitude) stored as map information in the database 19 and the current position (latitude and longitude) of the vehicle detected by the GPS receiver 13. When the distance is less than the predetermined distance, alarm information is output from the output device (GPS alarm function). Further, for example, when the signal corresponding to the microwave in the frequency band emitted from the speed measurement device is detected by the microwave receiver 14, the control unit 18 outputs alarm information from the output device (radar wave alarm function). Further, for example, when the control unit 18 receives a predetermined radio wave by the wireless receiver 15, the control unit 18 outputs alarm information from the output device (wireless alarm function). The radar detector 1 causes the driver to recognize a dangerous place where a traffic accident is likely to occur by outputting alarm information. Thereby, the radar detector 1 can urge the driver to drive safely. Note that the above-described alarm information is an example, and in fact, various other alarm information are output to the driver. The alarm information includes, for example, visual information including predetermined images, images, characters, and the like output to the display unit 4, and information using sounds and sounds output to the speaker 16. Specific alarm contents will be described later.

* Stand-by screen display The control unit 18 outputs alarm information for urging the driver to be safe when a predetermined event occurs. On the other hand, when such an event has not occurred, the control unit 18 displays a predetermined standby screen as shown in FIG. 3 as an example (standby screen display function). This standby screen display function displays various information useful for driving. For example, information based on GPS detected by the GPS receiver 13, such as speed, latitude, longitude, altitude, etc. , Display in an animation or other mode, or display the presence of GPS satellites detected by the GPS receiver 13 in a numerical value, animation or other mode, or based on predetermined OBD information / vehicle information acquired by the OBD II adapter 21 It is a function that displays numbers, graphs, animations, and other forms. The standby screen display function also has a MAP display function of accessing the database 19 based on the current position detected by the GPS receiver 13 and reading out and displaying the map data stored therein.

  FIG. 3A shows an example of a display screen output to the display unit 4 by the MAP display function. The control unit 18 reads and displays surrounding map information from the database 19 in the main display area R1 of the entire display screen of the display unit 4 from the current position of the host vehicle. An arrow-shaped host vehicle icon 31 is displayed at the position of the host vehicle on the map. The display position of the host vehicle icon 31 is a predetermined position determined in the main display region R1, and for example, the heading-up is fixed on the basis of the display position of the host vehicle icon 31 (displayed so that the traveling direction is always upward). As the map information. The display position of the host vehicle icon 31 is, for example, near the center on the lower side in the main display area R1.

  The control unit 18 has a function of displaying the first window W1 overlaid on the upper left corner in the main display area R1, and a function of displaying the second window W2 overlaid on the upper right corner in the main display area R1. . The first window W1 has a layout in which, for example, a traveling speed display unit is arranged on the upper side and a clock display unit is arranged on the lower side. The travel speed display unit displays the current vehicle speed of the host vehicle. For example, the control unit 18 calculates the speed from the displacement / history of the current position and the elapsed time based on the received GPS radio wave, or acquires the vehicle speed information from the vehicle via the OBDII adapter 21. Output the speed to the travel speed display. The clock display unit displays the current time, and the control unit 18 acquires the current time from, for example, an internal clock or GPS information, and outputs the current time to the clock display unit. In the second window W2, the place name and the road name of the current position are displayed.

  FIG. 3B shows an example of an acceleration standby screen, in which a large acceleration meter 32a is disposed on the left half side of the main display region R1, and two small meters 32b and 32c are disposed vertically on the left half side. The layout is such that the character meter 32d is disposed on the lower right side. The control unit 18 is a schematic diagram of the own vehicle in the accelerometer 32a and a diagram that shows the state of acceleration around the acceleration meter 32a so that the direction and intensity of the acceleration applied to the vehicle detected by the acceleration sensor 25 can be understood. Display the anime. In the initial value shown in the figure, an analog clock is displayed on the upper small meter 32b, a compass is displayed on the lower small meter 32c, and the vehicle speed is displayed on the character meter 32d. Information displayed on the small meters 32b and 32c may be changed by setting.

  FIG. 3C shows an example of the tilt standby screen, and in order from the left side of the main display area R1, the front / back tilt display unit 33a, the compass display unit 33b, and the left / right tilt of the vehicle The left and right inclination display part 33c which shows these is arrange | positioned. Based on the output of the acceleration sensor 25, the control unit 18 obtains the tilt angle in the front-rear / left-right direction of the vehicle, and displays the tilt angle state on the front-rear tilt display unit 33a and the left-right tilt display unit 33c. Expressed by direction and attitude. In the illustrated example, since the inclination angle is 0, both of the host vehicle are displayed horizontally.

  FIG. 3D shows a standby screen for a hybrid vehicle which is an example of a standby screen based on OBD information and vehicle information acquired via the OBDII adapter. This standby screen has a layout in which two minimeters 34a and 34b are arranged above the main display area R1 and hybrid information is displayed in the area below the two minimeters 34a and 34b. In this example, the control unit 18 displays the engine speed on the left side mini meter 34 a and displays the engine water temperature on the right side mini meter 34 b. The hybrid information includes engine speed 34c, engine water temperature 34d, HV air conditioner power consumption 34e, engine operation state (green: engine brake, red: engine drive) 34f, current engine running ratio / instantaneous fuel consumption 34g, generator power generation state 34h, front The motor operation state (green: regeneration, yellow: drive) 34i, the remaining battery level 34j, the linear motor state (green: regeneration, yellow: drive) 34k, etc. are displayed at appropriate positions.

* Alarm output based on event occurrence The control unit 18 executes processing to realize each function such as a GPS alert function, a radar wave alert function, a wireless alarm function, etc., according to the event that has occurred. Each alarm function switches the display of the display unit 4 from the various standby screens to a map screen for displaying a map around the position of the vehicle and warns in response to the occurrence of an event. The standby screen includes a screen displaying a map shown in FIG. 3A and a screen displaying information other than a map as shown in FIGS. 3B to 3D. For example, as shown in FIG. 4 and the like, the alarm screen for visually giving a warning is a map screen showing a map around the vehicle position displayed in the main display area R1 of the entire screen of the display unit 4 and its map The layout is such that a message window is displayed at a predetermined position on the screen. In this embodiment, the message window includes an alarm image display window W3 arranged at the lower left end and a message window W4 arranged at the lower right end. Details of the alarm function by the message window will be described later.

  The radar wave alarm function is displayed when the microwave receiver 14 detects a signal corresponding to microwaves in a frequency band emitted from a speed measurement device (a mobile radar or the like (hereinafter simply referred to as “radar”)). This is an alarm function that switches the standby screen to the alarm screen for display on the unit 4 (see FIG. 4A) and outputs an alarm sound from the speaker 16.

  For example, when the microwave receiver 14 detects a microwave in the microwave frequency band emitted by the radar, the control unit 18 reads a schematic diagram / CG or a photograph of the radar stored in the database 19 and displays an alarm image display window W3. , And information on the alarm is displayed in the message window W4. The control unit 18 displays the alarm screen and reads out the voice data stored in the database 19 and outputs a voice of “radar. Attention at speed” from the speaker 16.

  The wireless alarm function is a function to issue an alarm so as not to hinder the traveling or the like when the wireless receiver 15 receives a wireless radio wave emitted from an emergency vehicle or the like. In the radio alarm function, the control radio, car radio, digital radio, special radio, police radio, police phone, police activity radio, wrecker radio, heli tele radio, fire helicopter radio, fire fight radio, emergency radio, expressway radio , Scans the frequency of security radio, etc., and when a radio is received at the scanned frequency, a schematic diagram showing that the radio corresponding to the frequency stored in the database 19 for each radio type is received. The alarm screen displayed on the display window W3 is displayed on the display unit 4, and the voice data stored in the database 19 for each radio type is read out, and an alarm voice indicating the type of the radio is output from the speaker 16. For example, when a regulatory radio is received, it outputs an audio like "It is a regulatory radio. Speed caution".

  The GPS alarm function is a process that is executed at predetermined time intervals (for example, 200 ms intervals) by an event from a timer included in the control unit 18 during execution of the standby screen display function, for example, and the current position detected by the GPS receiver 13 And it is a function which judges whether alarm conditions (for example, predetermined approach relation) were fulfilled using alarm object information memorized by database 19, and when it fulfills, it will issue an alarm.

  First, examples of types of alarms include a snooze driving accident point, vehicle speed measurement device (radar type / H system / loop coil / LH system), mobile vehicle speed measurement area, speed limit switching point, control area, Inspection area, parking monitoring area, N system, traffic monitoring system, intersection monitoring point, signal ignorance suppression system, police station, accident-prone area, on-vehicle frequent occurrence area, sudden / continuous curve (highway), branch / joining point ( Expressway), ETC lane advance guidance (expressway), service area (expressway), parking area (expressway), highway oasis (expressway), smart interchange (expressway), PA / SA petrol station (expressway) ), Tunnel (highway), highway radio reception area (highway), prefectural border notice, roadside station, view point There are various types such as front parking, zone 30 area, and level crossing. For such various types, it is preferable not to display an alarm screen as an alarm target for all, but to issue an alarm for an object desired by a user selected by setting.

  The alarm target information stored in the database 19 is information related to each alarm target, and includes position information including longitude and latitude for specifying the position of the alarm target, and an alarm target useful for the driver to specify the alarm target. There is information for identification. In the present embodiment, the position information is absolute position information using longitude / latitude. This is preferable because the relative positional relationship with the current position detected by the GPS receiver 13 can be easily obtained.

  The alarm object identification information includes type information indicating the type of alarm object, character information indicating the position of alarm object, voice information indicating the alarm object, and image information indicating the alarm object. In the case where the voice information and the image information indicating the alarm object correspond to the type information of the alarm object, they are not stored as alarm object information for each alarm object, but are separately stored in a predetermined storage area as common information. It can also be done. When the alarm is issued, the control unit 18 can read out the type information stored as the alarm target information, acquire corresponding image information, audio information, and the like from the type target, and output an alarm.

  As common image information, there is image data such as a schematic diagram in which the type of alarm target can be easily understood. The schematic diagram is also a mark for enabling the type of alarm object to be intuitively understood from visual sense. For example, there is one in which a vehicle speed device, a police car, a policeman or the like is created as an image by 3D or the like. By drawing and outputting these schematic diagrams to the display unit 4 at the time of notification, it is possible to intuitively understand the type and content of the alarm object currently notified by the driver. And the own vehicle icon 31 is drawn on the own vehicle position on the display area of the display part 4, and the target icon 35 which consists of the said schematic diagram is drawn on the position of the location of a warning target (refer FIG.4 (b) etc.). Displaying the own vehicle icon 31 and the target icon 35 is more preferable because it can intuitively understand what alarm target is at which position.

  In addition, the audio information is output from the speaker 16 as audio information such as the relative positional relationship such as “Left direction 1 km ahead expressway H system”, “Immediately ahead general road N system”, the type of alarm target, etc. It is data for. In the above example, “Left direction”, “1 km ahead”, “immediately ahead” and other audio data indicating the relative positional relationship between the current position of the vehicle and the alarm target, and “general road N system” The voice data for specifying the type and content of the alarm target, such as “Highway H system”, is separately managed and stored, and when notifying, the control unit 18 combines and outputs the respective voice data.

  By separately managing fixed audio information (audio data) according to the type of alarm target, it is not necessary to register the same information as alarm target information for each alarm target, and it consumes memory space. You can reduce the amount.

  For example, the control unit 18 periodically accesses the database 19 based on the current position, and the distance between the loop coil that is the alarm target and the host vehicle is the approach warning distance stored in the database 19, which is 2 km, 1 km. , 500 m, the schematic diagram, CG or photo data of the loop coil to be alarmed is read from the database 19 and displayed in the alarm image display window W3, and information relating to the alarm is displayed in the message window W4. Display on The control unit 18 reads out the voice data stored in the database 19 and issues an approach notification that outputs a warning voice from the speaker 16. For example, when approaching 500 m, voice data “500 m ahead loop coil, attention to speed” is read from the database 19 and output from the speaker 16.

  Furthermore, the database 19 stores map data including road network information. The road network information is data necessary for searching for a recommended route in car navigation and the like, and includes information such as a road network (road layout) and traffic restrictions such as one-way traffic. Furthermore, this road network information stores the position information (latitude / longitude) of the node with the intersection of the road and the road or the inflection point of the road as a node, and the connection relationship of which other node is connected to each node. Information to be stored is stored. Thus, based on the information which shows the connection relation of each node, adjacent nodes are connected and it becomes a road link between the connected nodes. In addition, since guidance to a destination is not provided unlike a car navigation device, there is no detailed data such as display data of facilities and houses, and the data is simple.

[Setting function]
As described above, the radar detector 1 according to the present embodiment includes a notification function for the user, such as an alarm function for generating an alarm or the like when an event occurs. Furthermore, the radar detector 1 has a setting function of setting items related to the notification. Items related to this notification include, for example, items related to the entire system, such as screen brightness and base color, whether to perform alarms for a large number of prepared alarm targets, alarm methods, sound effects, etc. There are settings related to notification conditions and functions, and settings of optional items connected to the radar detector 1 such as an OBD II adapter. In this embodiment, in order to perform setting by the setting function easily and smoothly, the following various functions are provided.

(First menu screen with immediacy and second menu screen without immediacy)
When a predetermined operation is performed on the standby screen normally displayed, control unit 18 displays a first menu screen having immediacy, and a predetermined item on the first menu screen is selected. And a function to display a second menu screen without immediacy. The predetermined operation is, for example, a touch on the standby screen. As shown in FIG. 5A, the control unit 18 displays a predetermined standby screen on the main display area R1 of the entire display screen of the display unit 4. When the touch panel 5 detects a touch in the main display area R1, the control unit 18 switches the display on the display unit 4 from the standby screen to the first menu screen shown in FIG. The menu screen is displayed on the entire display screen of the display unit 4.

  The first menu screen includes a volume increase button 41a and a volume decrease button 41b as examples of item buttons that can be set immediately. The first menu screen also includes a setting button 41c for transitioning to the second menu screen. The first menu screen further includes a standby change button 41d, an item change button 41e, a registration button 41f, and a top button 41g. Arrange each button appropriately.

  The volume increase button 41a and the volume decrease button 41b are buttons for adjusting the volume. As shown in FIG. 6A, when it is detected that each button area is touched by the touch panel, the control unit 18 changes and sets the volume setting to one level, which is increased or decreased. The control unit 18 outputs a confirmation sound “beep” at the volume level after the change, and displays a level notification window W5 indicating the current volume level in the vicinity of the center of the first menu screen. The user hears this confirmation sound to determine whether it is appropriate or not, and further adjusts the volume by further touching the volume increase button 41a or the volume decrease button 41b as necessary. The volume is adjusted in 8 steps from 0 to 7, and the initial value is set to 5. When the volume level is set to 0, no sound alarm is given. Also, when the volume increase button 41 a is touched further in the state of “7” at which the current volume level is maximum, the control unit 18 outputs a warning sound “bubbling” without changing the volume level. . As described above, since the volume increase button 41a and the volume decrease button 41b are arranged on the first menu screen, the user can change and set the volume level simply by touching one of the buttons, and the setting with immediacy. Can do

  When it is detected that the standby change button 41d is touched (see FIG. 7A), the control unit 18 displays a standby change screen shown in FIG. 7B instead of the first menu screen. Display on 4 When it is detected that the registration button 41f is touched (see FIG. 7 (c)), the control unit 18 changes the first menu screen to register a point as shown in FIG. 7 (d). Is displayed on the display unit 4. As described above, the control unit 18 displays a screen for performing predetermined selection / registration or the like in response to the touch of the button.

  Further, when the top button 41g is touched, the control unit 18 displays the standby screen that is displayed at the normal time as the top screen. Moreover, the control part 18 performs the process which returns to the display of a standby screen, when it does not operate for a predetermined time after displaying a 1st menu screen. The predetermined time is, for example, 3 seconds.

  When it is detected that the setting button 41c is touched (see FIG. 5B), the control unit 18 displays a setting menu screen which is the top screen of the second menu screen shown in FIG. Display on the entire display screen. In the present embodiment, the items to be set are divided into three groups, and specific settings are performed from the setting menu screen provided for each group, so that the target item can be easily and smoothly reached and set. It is like that. The three groups are "system", "function" and "option". The system is a setting item related to the entire radar detector 1. For example, once set, a setting item that is often not changed as long as it is installed in the vehicle, or an initial setting item that is used at the beginning of use may be assigned. The setting items belonging to this system include, for example, brightness, base color, car type, etc. Specifically, there are nine items shown in the list in FIG. 8, for example.

  The function is a setting item for performing settings related to individual functions such as opening change and mode change, and it is preferable to assign a function that is sequentially changed during normal use. Setting items belonging to this function include, for example, a mode for specifying an alarm target to be notified, an alarm pattern for setting what kind of alarm display is performed, and more specifically, for example, 6 shown in a list in FIG. There is an item. The photo frame setting sets an image to be displayed on the standby screen, is a display setting in the standby function, and is a setting of a display mode in the notification function. Therefore, both are set items belonging to “function”.

  Options are the setting items when an optional accessory such as OBDII adapter is connected. For example, it is divided into OBD setting that is displayed only when the OBDII adapter is installed, and WLAN setting that is displayed only when the SD with wireless LAN function is installed. There is. Each of the OBD setting and the setting item belonging to the WLAN setting has a plurality of items.

  In the setting menu screen, the system button 42a, the function button 42b, and the option button 42c are arranged side by side in accordance with the three groups, the top button 42d is arranged small on the lower left side, and the title is displayed on the upper left side. The layout for arranging the part 42e is taken. In the title display part 42e, “setting” is displayed, indicating that it is a setting menu screen. When the control unit 18 detects that the top button 42d is touched, the control unit 18 switches to the top standby screen display (see FIG. 5A and the like).

  When the area of the system button 42a is pressed for a short time on the setting menu screen (see FIG. 10A), the control unit 18 displays a system setting screen as shown in FIG. 10B over the entire display screen of the display unit 4. indicate. As described later, the system setting screen is composed of three pages, and the first page is displayed. In this system setting screen, a title display portion 43a is arranged at the upper end, and a plurality of setting item display regions 43b are arranged in a vertical direction using a large number of regions below the title display portion 43a. A cursor button 43c is disposed above and below the right end, a page display section 43d is disposed at the center of the right end, and a button 43e returning to the lower side of the left end and a top button 43f are disposed.

  When the return button 43e is touched, the control unit 18 performs processing for returning the screen display to the screen one level higher, and here displays a setting menu screen. When the top button 43f is touched, the control unit 18 switches to the display of the standby screen. The title display section 43a displays "system setting" indicating that the system setting screen is displayed.

  The setting item display area 43b is formed horizontally long, provided with a title display portion 43b ′ for displaying the title of the setting item on the left end side, and provided with a setting content display portion 43b ″ for displaying the current setting content on the right end side. A predetermined number of setting item display areas 43b having such a configuration are arranged vertically.The predetermined number is four in the present embodiment.In the system setting screen of the illustrated page, in the setting item display area 43b at the top. The "brightness" is displayed as the title, and the setting content is "normal". As shown in FIG. 8, the setting value “brightness” can have three setting values “dark”, “normal”, and “bright”. Here, “normal” is the current setting content as the initial value. It shows that there is.

  In the present embodiment, since the setting content display section 43b ″ is provided at the right end of the setting item display area 43b of the system setting screen, the current setting content can be displayed without switching the screen and entering, for example, the setting change screen in the lower hierarchy. The user can easily know whether or not to change the settings for the setting items, and there is no need to switch the screen for confirmation.The user can check the displayed current settings, When it is desired to switch, for example, it is preferable to enter the lower setting menu screen, so that it is possible to quickly set the necessary setting items. Furthermore, since the title and the setting contents are displayed in pairs in one line display. It ’s good to know the relationship at a glance.

  The predetermined number is up to four. As described above, the setting item display area 43b is characterized in that four lines are displayed on one screen. By displaying in four lines in this way, the number of items that can be displayed on one screen is increased while ensuring the visibility of information displayed on the title display section 43b ′ and the setting content display section 43b ″, and one group In this embodiment, the number of setting items belonging to the system can be reduced, and the number of setting items belonging to the system is, for example, nine. The setting screen can be composed of three screens (see FIG. 11A) The switching to each screen is performed by touching the cursor button 43c.

  In this example, since it is composed of three screens, it is possible to confirm the whole with a small number of touches and find a target selection item. Therefore, after entering the system setting screen that is one lower level from the setting menu screen, confirming the contents immediately, making settings as necessary, and then returning to the upper screen by touching the return button 43e or the top button 43f. it can.

  As will be described later, the setting value candidate display unit 44b also functions as a button for transitioning to a lower setting change screen. Then, the button is selected by touching with a finger or the like, but by suppressing the display to four lines, a desired set value candidate display section 44b can be obtained without simultaneously pressing a plurality of set value candidate display sections 44b adjacent vertically. Good because you can touch exactly. Furthermore, in the present embodiment, although the display unit 4 uses a 3.5-inch size, by adopting four-line display, for example, there is no visibility and erroneous touch even with a 2.8-inch size. Operability can be ensured.

  When the setting item display area 43b other than the setting content display portion 43b ″ is touched, the control unit 18 displays a setting change screen for the touched setting item. For example, “brightness” in FIG. When the setting item display area 43b is touched, a setting change screen for brightness shown in FIG. 10C is displayed. The layout of the setting change screen is the same as that of the system setting screen. A title display portion 44a is arranged at the upper end, and a large number of areas below the title display portion 44a are used to set a plurality of setting value candidate display portions 44b. A layout in which a predetermined number is arranged so as to be vertically arranged, a cursor button 44c is arranged above and below the right end, a page display section 44d is arranged at the center of the right end, and a return button 44e and a top button 44f are arranged below the left end. Take. The title display section 43a displays "brightness selection" indicating that the setting item is "brightness".

  The maximum number of setting value candidate display portions 44b arranged on one screen is four. By limiting the number to four, each set value candidate display section 44b can have a vertical length, ensuring good visibility, and touching one desired set value candidate display section 44b. Such good operability can be ensured. Since there are three setting value candidates of “brightness” as the setting item, “dark”, “normal”, and “bright”, the fourth line is blank and fits on one screen. If there are five or more setting candidate values, a plurality of screens are prepared, and the screens are switched by the touch operation of the cursor button 44c.

  In the present embodiment, the number of setting candidate values to be set is set to four or less, and the number of setting candidate values is set in one screen. As a result, the user can list possible selectable setting values in the setting items to be subjected to the setting processing in one screen and can confirm at a glance, and can select and set desired ones. For example, if a large number of candidates of 5 or more is prepared, it is possible to make the setting more user-preferred, but it is necessary to take a lot of trouble while switching the screen to check the setting value candidates. Become complicated. As a result, the initial value is often used without setting, but in this embodiment, the target setting can be reduced by reducing the number of selectable setting value candidates and the number of setting items. This makes it easier to find a value and set it with a smaller number of processing steps.

  As shown in FIG. 8, for example, five setting value candidates are prepared for the setting items “base color” and “car type”. Accordingly, when such a setting item is selected, two setting change screens are displayed. Also for these setting items, it is more preferable that the number of setting value candidates is four or less because it can be displayed on one screen.

  Setting of setting values for setting items is performed in a state where desired setting value candidates are displayed. This setting is performed by touching the set value candidate display portion 44b. As shown in FIG. 10C, the control unit 18 displays a line 44h in the lower part of a frame that divides the area of the setting value candidate display unit 44b corresponding to the current setting content. In the figure, since “normal” is selected, a line 44 h is displayed on the center set value candidate display portion 44 b corresponding to the “normal”. In this state, for example, when the upper "dark" setting value candidate display unit 44b is touched, the control unit 18 sets the setting content for the selection item "brightness" to "dark", and the upper setting "dark". A process of displaying a line on the setting value candidate display section 44b is performed.

  When detecting that the function button 42b is touched on the setting menu screen shown in FIG. 5C, the control unit 18 displays the function setting screen (1/2) shown on the left side of FIG. 11B. As shown in the figure, the function setting screen has the same layout as the system setting screen, the title is “function setting”, and upon receiving a touch operation of the cursor button 44c, the control unit 18 displays the function setting screen (1/2). Switches the function setting screen (2/2) and displays it. As shown in the figure, in the setting item display area 43b of four lines in the first function setting screen, [mode] [alarm pattern] [opening] [photo frame setting] is displayed from the top. At the right end of the setting item of [Mode], [Normal] is displayed by default.

  When it is detected in the setting menu screen shown in FIG. 5C that the option button 42 c is touched, the control unit 18 displays an option setting screen. Although not shown, the option setting screen has the same layout as the “system setting screen” and “function setting screen”, the title becomes “option setting”, and [OBD] [OBD] [OBD] [ Take a layout to display WLAN.

  Then, when it is detected that the [OBD] button is touched on the option setting screen, the control unit 18 displays the OBD setting screen (1/2) shown on the left side of FIG. When it is detected that the button portion of [WLAN] is touched, the control unit 18 displays a WLAN setting screen (1/3) shown on the left side of FIG. In response to the touch operation of the cursor button 44c on each setting screen, the control unit 18 switches the screen to be displayed.

  As described above, in this embodiment, the first menu screen with immediacy displays all selectable item buttons in one screen, and the second menu screen for setting without immediacy is one. The displayed number of setting items displayed on the screen is limited to the standard value or less. In this way, the first menu screen with immediacy displays a list of operation buttons that can be selected on the first menu screen, so the user can immediately select the desired operation button and perform a desired process. You can In addition, the second menu screen has a four-line display layout in which narrow button areas are arranged vertically, but the first menu screen displays a list of six buttons (seven if the back button is included), It is characterized by not having a basic layout that is arranged vertically like the second menu screen. If 6 to 7 buttons are arranged vertically, they will cover 2 pages and cannot be displayed as a list. Therefore, they cannot be displayed without scrolling in a series, but they are appropriately arranged vertically and horizontally as in this embodiment. By displaying on the screen, the effect of the embodiment described above is exhibited.

  Since the number of displays in one screen of the second menu screen is limited, the setting items displayed on the second menu screen are easy to see, the target setting items to be set can be easily found, and the target setting is surely made Items can be selected. In particular, when the display number to be limited is exceeded, it is preferable to provide a plurality of sheets and a function of switching. In the embodiment, the switching function is realized by the cursor button. By limiting the number of displays, the number of second menu screens increases, but because there is no immediacy, it is possible to search slowly. In particular, when the selection of the setting item is a touch type with respect to the display screen, the number of displays is limited, so that, for example, the area of one setting item can be enlarged or the distance between adjacent setting items can be increased. Therefore, there is no need to accidentally touch different setting items or simultaneously press a plurality of adjacent setting items, which improves operability.

(Automatic return function to standby screen etc.)
As described above, when touched on the standby screen (see FIG. 5A, etc.), the control unit 18 displays the first menu screen (see FIG. 5B, etc.), but the screen operation is performed for a certain period of time. If not, the control unit 18 has a function of returning to the display of the original standby screen. The fixed time may be, for example, 3 seconds.

  Since the first menu screen with immediacy has a list of selectable operation buttons, for example, the user can see whether there is an item with immediacy to be processed by looking at the first menu screen. If there is no item, it can be automatically returned to the standby screen if it is left as it is. Since the first menu screen is a button for performing processing with immediacy, a user who wants to perform various types of processing / setting presses the button for the next operation if there is a fixed time such as 3 seconds, for example. Because it is supposed, you may make it return to the stand-by screen automatically.

  Furthermore, after the setting button 41c is pressed on the first menu screen and the system setting screen is displayed, it is preferable not to transition to the original screen even if there is no screen operation for a certain period of time. Since the second menu screen is a screen for setting without immediacy, there are cases where the user sees the displayed screen and how to make the setting, and there is no screen operation for a certain period of time. In such a case, when the original screen is restored, it is necessary to perform an operation for transitioning to the screen for processing again, which is complicated. Therefore, it is preferable that the automatic return can be performed slowly and the operation can be surely performed.

  In addition, it has a radar cancellation function that stops the alarm when the screen is touched during an alarm accompanied by radar wave reception. For example, when the screen is touched for the radar cancel function, the first menu screen is displayed for those who touch the screen to stop the alarm. It is a disturbing operation and there is a demand to immediately return to the original standby screen. Therefore, it is preferable to return within a relatively short fixed time, for example, 3 seconds. Then, in the case of a person who wants to make settings after that, the button for the next operation will be pressed if there are 3 seconds, so it is good because there is no automatic return.

  Also, when the screen is touched during the radar alarm, the alarm is stopped and the radar is canceled, but it is preferable not to display the first menu screen. The touch during the alarm may be continued as the standby screen can be displayed by not transitioning the screen as an operation for canceling the alarm.

(Setting value changing function using setting content display section 43b ")
In the above-described embodiment, in each setting screen, a predetermined number of setting item display areas 43b are arranged vertically, and in each horizontally-long setting item display area 43b, a title display portion 43b 'for displaying the title of the setting item and The configuration is provided with a setting content display section 43b ′ ′ for displaying the current setting content, and the current setting content can be confirmed with the setting screen as it is. To change the setting value of the setting item, It is necessary to touch a predetermined position of the setting item display area 43b to switch to the display of the setting change screen.

  It is preferable that each setting screen provided with the setting item display area 43b also has a function of changing / setting the item value of the setting item. For example, it is preferable to have a function of changing the current setting contents without displaying the setting change screen when the setting content display section 43b ′ ′ displaying the current setting contents is operated as a setting value changing / setting function. The operation on the setting content display section 43b ″ may be, for example, a touch on the part.

  This function may be used in the case of two to three few setting value candidates, in particular two. For example, in the case of two, when it is detected that the setting content display section 43b ′ ′ is touched, the control section 18 sets another setting content that is not the current setting content as the current setting content, and the setting content display section 43b ′ ′ Switch the display. For example, as shown in FIG. 9, since the set values of the alarm pattern are two types of "CG photo shooting alert" and "telop alert", for example, the setting contents are displayed with "CG photo shooting alert" displayed as an initial value. When the display 43b ′ ′ is touched, the set value is set to the “ticlop alarm”, and the “detailed alarm” is displayed on the set content display 43b ′ ′. Further, when the setting content display section 43b ′ ′ is touched from that state, the setting value is set to the “CG photographing alarm”, and the “CG photographing alarm” is displayed on the setting content display section 43b ′ ′. It is also suitable for settings that turn on / off certain functions.

  When there are three or more set values, it is preferable to use a toggle type in which the set values are changed one by one in a predetermined order every time the setting content display section 43b ″ is touched once. In the case of, for example, displaying the setting value candidate to be switched by the toggle method in response to the touch of the setting content display section 43b on the lower setting change screen and making it smaller than the selectable setting value candidate is necessary to go around The number of unnecessary touch operations can be reduced, so that the trouble is eliminated. If you want to reduce the toggle type, you should set it so that a representative one is displayed. By adopting such a configuration, the setting contents of the setting items can be set by operating the setting contents display section 43b ″ without changing to the lower layer setting changing screen. It is not necessary to repeat the screen transition with the setting screen displayed on four lines, and the operation is also simple because it is only necessary to touch a predetermined position on the setting screen once in this embodiment, and the operability is good.

  Furthermore, when the number of setting value candidates is equal to or greater than the reference value, it is preferable that the setting contents are not switched even if the setting content display unit 43b ″ is operated. If there are many cases where there are many candidates, even if the number of candidates is large, there is a risk that even if the setting content is changed by touching the trial, the desired setting content may not be obtained. In the case of the reference value or more, the occurrence of such a situation may be suppressed by not changing the setting contents even if there is a predetermined operation such as touching the setting contents display section 43b ″. Furthermore, in the case where the setting content is not changed, it is more preferable to transition to a lower setting change screen.

(Display on setting content display section 43b ′ ′)
The display information for specifying the setting value to be displayed on the setting content display portion 43b ″ and the display information for specifying the setting value to be displayed on the setting value candidate display portion 44b of the lower setting change screen may be the same. The display information for the setting content display section of the setting menu screen and the display information for the setting value candidate display section of the setting change screen are provided as separate data structures, and the respective display information indicating the same contents is the setting contents For the display part, it is preferable to have a simple expression, for example, a mark or a symbol may be used, but a term having a small number of characters may be used, and in the case of reducing characters, an abbreviation may be used. .

  In particular, the setting content display section 43b ″ is provided in a part of the setting item display area 43b and is narrower than the display area of the setting value candidate display section 44b, and particularly has a short horizontal length. For example, if the number of characters in the setting content becomes long, it may not fit in the display area, and the meaning content may be difficult to understand.Therefore, considering that the display area has a short horizontal length, By using display information that can be understood, the setting content displayed on the setting content display section 43b ″ can be easily understood, and it can be determined whether the setting needs to be changed. On the other hand, since the set value candidate display section 44b is long in the horizontal direction, the display information can be displayed with sufficient length, and the contents can be easily understood when the setting change screen is displayed. After understanding the contents of the value, you can set the user preference.

  When displaying the current setting contents in characters, the display of the setting contents display section 43b ′ ′ should display the one created with one picture instead of the font. The setting contents display section 43b ′ ′ has a small display area area Therefore, it will be difficult to see if a font is used, but it is preferable to display what created each setting content as one picture, because the character part becomes clear and easy to see.

  In the setting menu screen, the current setting content can be displayed in the display area of the setting item, and the user can understand the content without hesitation. Then, in the state of transition to the actual setting menu screen, the setting content as the selection candidate is correctly displayed, and the user can correctly understand the content.

(Mode setting function)
Also on this function setting screen, when it is detected that the setting item display area 43b is touched, a setting change screen for the touched setting item is displayed. Although illustration is omitted, when [mode] is touched, a setting screen for the mode (from above, displaying normal, all on, and manual selection candidates) is displayed. As shown in FIG. 12, the correlation between some setting items and setting values is “fixed mode” and “all on mode”, and the user can not set ON / OFF individually for each setting item. On the other hand, when [Manual mode] is selected, setting values can be changed and set individually for all setting items. Although specific illustration is omitted, the setting items are divided into three groups of [radar / wireless], [GPS] and [others], and setting items are selected and set in group units.

  In order to realize the configuration, when the manual mode is selected, the control unit 18 first displays a screen provided with three selection buttons of [radar / wireless], [GPS], and [others], and any of the buttons is When touched, a setting menu screen in which setting items belonging to the group are arranged four by four vertically is displayed, and when one of the setting items displayed on the four lines is touched, the control unit 18 It has a function of displaying a setting change screen for the touched setting item and changing and setting the setting content based on the touch on the setting content display portion 43b ″.

  There are many setting items whose setting values can be changed in the manual mode. As described above, even if it is divided into the three groups of [Radar / Radio], [GPS], and [Others], “GPS” is particularly used for position information. Because there are many alarm targets based on this, the setting menu screen for GPS will exceed 4 pages. In this embodiment, the number of setting menu screens is set as an exception so as to exceed the reference number of three pages, for example, without dividing as [GPS1] [GPS2] [GPS3] in accordance with the principle of three or less pages. did. If the alarm target based on the position information is divided into a plurality of GPS groups and classified so as to fit in the new screen to the third setting, the user does not know which item belongs to which GPS group. It is necessary to look at each group in order to look for the group that is, and rather it becomes inconvenient. So, GPS was put together in one group.

  Furthermore, the initial value of “manual mode” is set to the minimum mode setting contents for turning on the minimum necessary setting items. Accordingly, if the manual mode is selected and the initial value is used, the operation setting with few alarms may be obtained. If the user wants to make individual settings according to the user's preference, the user can set the alarm condition / alarm type of his / her preference by selecting the manual mode and individually setting each selection item. Once set, the contents are saved with the contents. For example, when manual mode is selected again after selecting another mode, the ON / OFF of each setting item is the same as the contents set immediately before saving. Do. In the present embodiment, the manual mode literally combines two modes: a mode for literally setting manually and a minimum mode for performing the minimum required alarm.

(Description pop-up display function)
When the first operation is performed on the setting item displayed on the second menu screen, there is a function of performing processing for setting of the setting item, and there is a second operation different from the first operation. In this case, it has a function of displaying a description pop-up screen that explains the contents of the setting item. The first operation may be a short press, and the second operation may be a long press. The function for performing the setting process may be, for example, a function for displaying another screen or changing the setting content based on the touch on the setting content display unit 43b ″ described above.

  In the explanation pop-up screen, for example, a description of the selected setting item being displayed, for example, a general commentary and explanation on the item which has been long pressed, "If you set it as OO, it moves like this", " It is a function to display on the display screen the explanation of the contents of the setting such as "to give an alarm when this is turned on". In this case, for example, when the user does not know the content displayed on the display screen of the display unit 4, the user presses and holds the content. When detecting the long press, the control unit 18 displays a corresponding explanation pop-up screen. Therefore, the user can check the displayed contents of the explanation pop-up screen, and can instantly know the contents he / she wants to know without taking out the instruction manual or the like and searching for the corresponding page. While the "setting item" is actually displayed, long press on the "setting item" to display the explanation about the "setting item". When the user operates the "setting item", what kind of You can understand whether the setting will be performed, you can easily judge whether the setting is necessary for you, and if necessary, you can change the setting immediately.

  For example, as shown in FIG. 13A, a setting item display area 43b for displaying a predetermined setting item (“brightness” in the example in the figure) while displaying a system setting screen which is an example of the second menu screen. When it is detected that the key is pressed for a long time, the control unit 18 causes the display unit 4 to display an explanation pop-up screen as shown in, for example, FIG. For example, when it is detected on the system setting screen shown in FIG. 13A that the “base color” setting item display area 43b has been pressed for a long time, the control unit 18 causes the display unit 4 to display, for example, FIG. Display a description pop-up screen as shown in.

  The explanation pop-up screen has a layout including a content explanation display unit 45a disposed in the main display area R1 of the entire display screen of the display unit 4 and a close button 45b disposed in the lower right of the content explanation display unit 45a. The explanation pop-up screen is displayed on the entire surface of the display unit 4. By this display, the screen (here, the system setting screen) displayed before it is not visible. In the non-visible state, for example, while displaying the screen displayed before that, the explanation pop-up screen may be displayed superimposed on the screen, but the screen before switching the screen display is not displayed. It is recommended to display the pop-up outer surface. As illustrated, the contents of the explanatory text displayed on the contents explanation display unit 45a display a general explanation, and do not indicate setting values that can be specifically set.

  This explanation pop-up screen is prepared for each item arranged on each screen for all the second menu screens including the setting menu screen which is the top screen of the second menu screen shown in FIG. The information is stored in the detector 1, and the control unit 18 calls up an explanation pop-up screen for the item that has been pressed for a long time, and switches and displays it on the display unit 4. For example, when the system button 42a is long pressed on the setting menu screen, the control unit 18 switches and displays the explanation pop-up screen for explaining the system shown in FIG. 13D, and when the function button 42b is long pressed, The control unit 18 switches and displays the explanation pop-up screen that explains the function shown in FIG. 13E, and when the option button 42c is pressed for a long time, the control unit 18 explains the option shown in FIG. 13F. Switch screens. In each figure, the explanatory text to be displayed on the content explanation display unit 45a is specifically exemplified, but a general explanation is displayed and a setting item to which it specifically belongs is not shown.

  If it is detected that the close button 45b is touched while displaying the explanation pop-up screen, the control unit 18 erases the display of the explanation pop-up screen and displays the screen displayed immediately before.

  In addition, as described above, the second menu screen is provided with a description pop-up screen for all items in principle, and has a function to display a corresponding description pop-up screen based on a long press on the screen. The back button and the top button in the second menu screen are characterized in that the explanation pop-up screen is not prepared. Users who operate these buttons to return to the top screen or the previous screen tend to continue to press and hold those buttons until the screen is switched, for example, and continue to press and hold the button until normal screen operation. Is an unexpected process by the user, which is rather annoying. Furthermore, the contents of the back button and the top button can usually be understood, and it can be said that the explanation by the explanation pop-up screen is unnecessary. Therefore, in this embodiment, as described above, the explanation pop-up screen is not provided for the return button and the top button, and the explanation pop-up screen is not displayed even if the button is pressed for a long time.

  The explanation pop-up screen may be prepared on the stand-by screen or the first menu screen, but in this embodiment, the explanation pop-up screen is not displayed even if it is pressed for a long time on that screen. The item to be selected on the first menu screen is a button for selecting and instructing what to want right away, such as having immediacy, so the user strongly desires to perform the processing having that immediacy, and the normal operation But sometimes I keep pressing it for a long time. For example, the volume increase button 41a and the volume decrease button 41b are buttons for setting with an immediacy to increase or decrease the current volume. It is a button for making a transition to the second menu screen, and a registration button 41f is also a button for making a transition to the menu screen for registration immediately in order to register the current point; It is easy to keep pressing each button until transition. In such a case, it is troublesome if the explanation pop-up screen is displayed, so that the explanation pop-up screen is not displayed on the first menu screen. In addition, since these buttons are also items that need to be explained on the explanation pop-up screen in an easy-to-understand manner like the back button and the top button described above, in this embodiment, the setting is made not to display the explanation pop-up screen. did.

  On the other hand, for example, after the setting button 41c is touched and the screen display changes to the second menu screen, for example, there are many cases where parking and stopping are in progress, and there is time margin, as described above. In order to provide explanations on the explanation pop-up screen and make appropriate settings, explanation pop-ups have been prepared for all setting items except the screen transition buttons such as the back button and top button.

  In the standby screen, for example, the screen is touched for canceling the radar, but the user tends to keep pressing until cancelled. It is troublesome if such an event is determined as a long press and an explanation pop-up screen is displayed. Therefore, as in the first menu screen, the setting is made so that the explanation pop-up screen by long press is not displayed on the standby screen.

(Car type setting function)
In this embodiment, for example, as shown in FIG. 8 as the “car type” setting value prepared in the second setting item display area 43b from the top in the system setting screen shown in FIGS. 10 (b) and 13 (a). In addition, five types of "small car", "sedan 1", "sedan 2", "SUV" and "minivan" were prepared. When the setting item display area 43b is touched, the control unit 18 displays a setting change screen for a car type, and sets the car type by a touch operation on the screen. By setting such a car type, as shown in FIG. 14, the shape of the schematic diagram 50 of the host vehicle displayed on the standby screen and the display mode of the wheel 51 are matched to the set car type. By doing this, the user feels as if his / her vehicle has been displayed, and it is good because he is happy. 14A is “Small car”, FIG. 14B is “Sedan 1”, FIG. 14C is “Sedan 2”, FIG. 14D is “SUV”, and FIG. 14E is “Minivan”. The standby screen for “” is shown. Although the specific illustration is omitted, the shape of the vehicle displayed on the accelerometer also changes with the setting of the car type.

[CG & Live action warning]
FIG. 15A shows an example of alarm operation timing by the GPS alarm function. As described above, the control unit 18 displays a standby screen that is normally displayed on the display unit while the host vehicle 62 is traveling or the like. Then, the control unit 18 periodically accesses the database 19 based on the current position, and switches to the map screen when the distance between the alarm target 61 and the vehicle 62 reaches the approach warning start distance stored in the database 19. To start. Then, the control unit 18 reads the CG or photo data of the alarm target 61 from the database 19 according to the distance between the host vehicle 62 and the alarm target 61, displays the data on the alarm image display window W3, and displays information about the alarm as a message. They are displayed in the window W4 (see FIG. 15B etc.).

  In the present embodiment, a first alarm (see FIG. 15C, etc.) that displays a moving CG stored in the database 19 and a real image obtained by shooting an image corresponding to a scene including the alarm target are displayed. The second alarm is output (see FIG. 15D, etc.), the first alarm is output to the alarm image display window W3, and then the second alarm is output. Since the image corresponding to the scenery including the alarm target by the second alarm is displayed after the user is alerted by the CG that moves by the first alarm, it is easy for the user to recognize the alarm content. .

  The control unit 18 controls the LED light emitting unit 6 to blink in a predetermined light emission color when the warning start distance is reached. The predetermined color is any one of red, yellow, green, and blue according to the type of the alarm target. As will be described later, the background display color in the message window W4 and the target icon drawn on the alarm target map It is the same color as the 35 base colors. The same color may be a color of the same color system, but may be the same color. When the control unit 18 starts blinking light emission of the LED light emitting unit 6, for example, when the distance between the host vehicle 62 and the alarm target 61 passes by 0 or the alarm condition such that the distance is more than a predetermined distance is removed, for example. good.

  CG with motion is CG corresponding to the type of alarm target, and for example, as shown in FIG. 16, from a state where the view such as in the city including the alarm target 55 is viewed from a distance with a view (FIG. 16A), The screen is enlarged and zoomed so that the area occupied by the alarm object 55 gradually becomes larger in the screen, and the alarm object is approached (Fig. 16 (b) to (h)). It should be a movement that comes in the middle. By making such a movement, it is easy for the user to understand what kind of alarm target the user is. In addition, instead of reproducing the approaching on the road, for example, the moving object is gradually lowered and approached from the state seen from the sky, and the moving object is raised, such as moving up and being raised from the front; The instruction icon 56 indicating the position of the alarm target 55 in the CG image may be displayed in an overlapping manner. In the illustrated example, the instruction icon 56 is an initially rectangular frame, and is deformed so as to be annular in shape and to be thick and conspicuous as the alarm target is approached and enlarged. By drawing the instruction icon 56 in this way, it is easy to focus on the alarm target 55 in the screen, and the type can be recognized more easily.

  Furthermore, the moving CG is such that the entire window other than the alarm target 55 is covered with a translucent color that is the same color as the light emission color of the LED light emitting unit 6 from the middle, and further the color other than the alarm target 55 is covered. The opacity of the is gradually increased. By doing so, it is more preferable that the alarm target gradually rises, and it is preferable that the urgency can be understood to a lesser extent by unifying the background colors of the CG, the LED light emitting unit 6, and the message window W4. In the illustrated example, since the alarm target is the LH system, it is intended to be unified in red.

  It is good for the live-action picture to be displayed following the reproduction of CG with motion to be an image that looks like the view seen from the driver's seat of the running vehicle, and in this embodiment the subject is subject to the alert in the place where the alert target is actually installed. We used a real-shot image consisting of image data shot so that Further, the present invention is not limited to such a real shot image, and for example, a scene seen from the driver's seat of a running vehicle may be created by image data such as CG, etc. It is good because it increases. As shown in FIG. 15D, it is preferable to draw an instruction icon consisting of an arrow 57 indicating an alarm object in the photographed image so that it can be known at a glance where in the photographed image the alarm object exists. The user sees the photographed image displayed in the alarm image display window W3 and confirms the scenery and the position of the alarm object in it, thereby finding the existence of the alarm object from the scenery actually seen forward during traveling It will be easier.

  The CG shown in FIG. 16 described above is an example of an LH system where an actual device / device is identified, and among the types of alarm targets, for example, a specific device such as a control area Some devices are not identified. 17 (a) to 17 (i) are a part of a frame constituting a CG of an example of a control area of an example of an alarm object whose installation position / state is not uniquely identified. Reference numeral 17 (j) denotes a real image.

  As shown in FIGS. 17 (a) to (i), the zoom is gradually increased from the state in which the alarm target 55 is almost invisible, and finally the alarm target imitating a mobile speed measuring device and a police officer operating it. The instruction icon 58 is a ring-shaped body whose diameter gradually changes, and the screen is covered with a semi-transparent yellow so as to be unified in yellow.

  In the case where control is not performed in a permanent manner, such as in a control area, the actual image may be image data obtained by photographing the location where the control is performed as shown in FIG. 17 (j), for example. When the image is not photographed, an arrow 57 or the like indicating a specific place / device is not drawn. When there is no arrow in particular, the user should check that the front view seen through the windshield while driving is in the same place as the live-action, and that it is a place that should be run with great care and traffic accidents. recognize.

  It is preferable that CG with motion by the first alarm be reproduced by repeating a series of motions multiple times. Since the motion is replayed a plurality of times, the first alarm by CG may be noted. For example, if the CG is related to the type of alarm target, the type of alarm target can be recognized by the first alarm, and then the actual situation can be displayed by displaying an image corresponding to the scenery including the alarm target. It is good because you can understand.

  As described above, the control unit 18 controls the alarm image display window W3 to output the actual shooting by the second alarm following the reproduction of the CG by the first alarm, and outputs the CG of the first alarm, It is advisable to carry out the operation continuously without providing a time lag between the output of the live action by the second alarm. In this way, by displaying the actual shooting continuously as it is after CG reproduction, it is possible to intensify the relevance between the notification of the type of the alarm object by CG and the notification of the actual situation by the actual shooting. Furthermore, since the CG is such that the alarm target is zoomed up last, the actual situation can be understood while the type of the alarm target is strongly recognized and the type is still recognized.

  Further, as shown in FIG. 18 (a), the control unit 18 may control to display the first alarm image and the second alarm image so as to overlap each other on the alarm image display window W3 during a certain period. In the overlapping display section, the opacity ratio of the CG image and the opacity ratio of the live-action image are gradually changed, and the appearance of the two images displayed in the alarm image display window W3 is displayed first. It is preferable to make a smooth transition from the first image to the next labeled image. In this way, in the fixed section, both images are drawn, and the opacity of each image is gradually changed, so that the connection / continuity between the first alarm and the second alarm is strengthened.

  An example of such control is shown in FIGS. 18 and 19. For example, in FIG. 18B, only the CG image of the first alarm is displayed in the alarm image display window W3. In FIG. 18C, the CG image of the first alarm and the second alarm are displayed in the alarm image display window W3. In FIG. 18D, only the actual image of the second alarm is displayed in the alarm image display window W3. Also, in FIG. 19A, only the CG image of the first alarm is displayed in the alarm image display window W3, and in FIG. 19B, the CG image of the first alarm and the second in the alarm image display window W3. The real image of the alarm is displayed in an overlapping manner, and FIG. 19C shows a state in which only the real image of the second alarm is displayed in the alarm image display window W3.

  The control part 18 is good to make it repeat the process displayed by a 2nd alarm in multiple times after the display by a 1st alarm. For example, as shown in FIG. 18 (a), after CG reproduction by the first alarm is performed, after actual photographing by the second alarm is output, CG reproduction by the first alarm is performed again, and then actual photographing by the second alarm is output It is good to repeat such processing.

  For example, if the second alarm is continuously displayed after the first alarm, the display time of the second alarm will be longer if not repeated, and the attention to the first alarm displayed first is reduced. May end up. After the second alarm, by displaying the first alarm composed of CG corresponding to the type of the alarm target, attention may be paid to the first alarm. For example, even a user who overlooks the first alarm first can visually recognize the first alarm and recognize the type of the alarm target. In particular, when the second alarm is a still image, it is difficult to attract attention if an image without motion is continuously displayed. Especially while driving, it is not possible to look at the display screen of the display unit 4 of the radar detector 1, but by appropriately displaying the first alarm consisting of moving CG, movement is generated in the peripheral vision of the user, It is good because it can be made to recognize that there is an alarm target to be careful.

  The display time of the first alarm may be, for example, several seconds or 2-3 seconds. If there is enough time, the movement can be recognized, and when the user looks at the screen along with the recognition, the second alarm such as a live-action is displayed if the user waits about 2 to 3 seconds at the longest. The contents of the second alarm can be confirmed without watching for a long time. Furthermore, after displaying the actual landscape image with the real image of the second alarm, by notifying the CG according to the type of the alarm target by the first alarm, the CG is also noticed and displayed by the second alarm. It is good because the understanding of the type of alarm target is deepened.

  Thus, when repeatedly performing the first alarm and the second alarm, for example, as shown in FIG. 18A, when switching from the second alarm to the first alarm, both images are drawn in a partial section, The connection between the second alarm and the first alarm may be strengthened by gradually changing the opacity of each image. An example of this control is shown in FIG. 19C, from the state where only the real image of the second alarm is displayed in the alarm image display window W3, to the first alarm image display window W3 shown in FIG. When a transition is made to a state in which only the first CG image of the first alarm is displayed in the alarm image display window W3 shown in FIG. good.

  The time for performing the first alarm and the time for performing the second alarm may be the same. Also, as described above, for example, in the case of giving an alarm by voice at 2 km, 1 km and 500 m which are approach warning distances, at the first and second warnings, CG reproduction by the first alarm and actual output by the second alarm are output. After repeating the predetermined number of times, the alarm using the alarm image display window W3 is stopped and the alarm image display window W3 is not displayed, and the alarm using the alarm image display window W3 is continued when reaching the nearest approach warning distance as 500 m. And do it. Continuation should be performed until, for example, the alarm target condition is not satisfied due to a route change or the like even if the alarm target is passed or not, and in such a case, the alarm image display window W3 may be hidden. .

  In the embodiment described above, the actual shooting by the second alarm is a still image, but may be a moving image. In the case of a moving image, reproduction may be performed regardless of the vehicle speed or to be earlier than the vehicle speed. Further, since the CG that moves due to the first alarm also increases so as to approach the alarm target, the moving image reproduction speed of the actual vehicle may be the same speed as the speed of the approaching movement in the CG. By doing the same, the continuity and sense of unity of the first alarm and the second alarm can be increased.

  20 and 21 show an example of alarm / information notification using the message window W4. The message window W4 is a window for displaying various alarms at the time of alarm or notification, and is superimposed on the map and displayed like the alarm image display window W3. Along with the display of this message window, control for shifting the display position of the map or reducing the display area of the map is not performed. The user can confirm necessary information by looking at the message window W4. Since the display position of the map is not shifted or the display area of the map is not reduced, the map on the display unit 4 and the position of the vehicle on the map do not change. When the own vehicle icon 31 is displayed at the bottom center of the display unit 4 in the case of heading up, the display position of the alarm image display window W3 or the message window W4 is the left side or the right side of the own vehicle. The map information hidden by the window is less important because it is not a place immediately after the host vehicle traveling at present, since the map information hidden by the window is placed at a predetermined distance from the position. Furthermore, regardless of display / non-display of the alarm image display window W3 and the message window W4, the display area of the map screen is the entire screen of the display unit 4 and a large area can be secured.

  The notification information using the message window W4 is appropriately set according to the level of urgency of the alarm target, and the background color is also red, yellow, blue, green (high level → low) according to the level of urgency. Prepared. Although this background color will be described before and after, the light emission color of the LED light emitting unit 6 and the base color of the target icon 35 are the same. “Strict caution” targets with the highest level of urgency, such as loop coils, warn against a red background, and display the type name of the alarm target and radio wave reception as a level. For example, FIG. 20A is an example of a display layout when the alarm target is “control radar wave”. The alarm target type display unit 60a (displays the type of control radar wave) and the reception level display unit 60b (1 (low) ) (High) to 5 (high), the current speed display section 60c is arranged. The background color is red. FIG. 20B is an example of a display layout when the alarm target is “GPS target”. The alarm target type display unit 60a (displays the type of GPS target) and the speed limit display unit 60d (position of the speed measurement device or the like). The current speed display unit 60e, the alarm direction display unit 60f (the direction of the GPS target is displayed in the direction of the arrow), and the remaining distance display unit 60g are arranged at appropriate positions. The speed limit and the current speed are easy to understand because they are arranged side by side in one window. The background color is red. FIG. 21 (a) shows an example of a small orbis alarm.

  The second "High Caution" target from the top, such as the enforcement area, warns with a yellow background and counts down the target name and the distance to the target. For example, FIG. 20C shows a display layout example when the alarm target is “digital wireless”, and the layout for arranging the alarm target type display section 60a (displays the type of radio) and the current speed display section 60c is taken. . The background color is yellow. FIG. 21 (b) shows a warning example of a level crossing without opening.

  The “little attention” target whose level of urgency level is the third from the top, such as a continuous curve, is notified with a blue background, and the target name and current speed are displayed. FIG. 21C shows a notification example of a police telephone.

  “Information for safe driving” having the lowest level of urgency such as an ETC lane is notified with a green background, and the target name and current speed are displayed. FIG. 21D shows an example of a new emergency radio.

  An arrangement layout using such a message window W4 may be prepared for each alarm target. The message window W4 on the right side is displayed in large letters, and if the alarm screen is viewed, the situation is known for the time being, and it is good because it is possible to concentrate on driving with peace of mind while traveling.

[Display function for public control information]
FIG. 24 is a diagram for explaining a display function of public control information. For example, public police information on the date and time and place where traffic control is to be conducted, for example, is announced from the Tokyo Metropolitan Police Department and the prefectural police station. In addition, the speed management guidelines show the policy of speed restrictions and traffic control in each prefecture based on the traffic actual conditions such as traffic accident occurrence status and the necessity of speed control, etc. It is. Based on the policy shown in the speed management guidelines, the speed control guidelines focus on speed control based on analysis of traffic accidents and requests from local residents, etc., for general roads and expressways within each police station area. The route, time zone, etc. to be performed are clearly shown. It is a guideline compiled for each police station. These pieces of information are stored in storage means such as a memory card, and it is preferable to update to the latest information. For example, it is preferable to store information related to traffic though not directly related to traffic safety week and the like.

  The control unit 18 accesses the storage means at startup or while traveling, and searches for public enforcement information, speed enforcement guidelines, and other information related to traffic based on the current position and along the road around it or traveling. For example, when displaying the map screen on the standby screen, as shown in FIG. 22 (a), the control unit 18 blinks the background color in red with the disclosure control information having the disclosure control information, and has the speed control pointer The control route 71 blinks the background color of the road in blue.

  For example, when the control unit 18 enters a route having control information, the control unit 18 displays the control information screen shown in FIG. 22B on the display unit 4 for a predetermined time, and returns to the original screen. The predetermined time is, for example, 10 seconds. FIG. 22B shows a control information screen for displaying public control information, which is a public control information screen. On the enforcement information screen, the date information display part 72b is arranged on the upper left side, the current time display part 72c is arranged on the upper right side, the enforcement type notification part 72d is arranged on the lower end, and the information display part 72a is provided in many other areas. . The acquired control information is displayed on the information display part 72a. Information is displayed on the information display section 72a without scrolling. If the scroll display is not seen for a long time, the whole picture is not known, and if you miss the first time, you have to wait for a round, but in this embodiment, the user does not scroll and displays it all together. It is good because you can know the information you want to know efficiently.

  When the information to be displayed does not fit on one page, the control unit 18 switches the display to two pages when the first page is displayed for a predetermined time without scrolling, displays the predetermined page for a predetermined time, and controls information when the last page is displayed for a predetermined time. Control to turn off the screen and switch to the original screen. Further, when the control unit 18 detects that the screen is touched while displaying the control information screen, the control unit 18 erases the display of the control information screen and performs processing for returning to the standby screen. By providing the function of returning to the standby screen by touching the screen as described above, it is preferable because the control information screen can be erased without waiting for a predetermined time.

  Furthermore, when the predetermined part of the standby screen is touched (see FIG. 22C), the control unit 18 displays the control information screen for a predetermined time (see FIG. 22D). The predetermined part is at the upper left of the standby screen. Even if the disclosure control information screen disappears and is missed, it can be redisplayed with a simple operation and the content can be confirmed.

  Even when the predetermined portion of the standby screen is touched, the control unit 18 may not display the open control information screen when there is no control information on the traveling route. As a result, when the control information screen is not displayed even when touched, it can be understood that the road on which the vehicle is traveling is not relevant, and thus it is preferable because the driver can safely drive and travel.

  The control unit 18 causes the control type notification unit 72d to emit light of red / blue in accordance with the type of control, so that information about what is known from the color. The luminescent color is the same as the background color of the road, and is red for public control information and blue for speed control guidelines. When the control type is displayed in characters, it is difficult to find the first display in the scroll display, even if it is displayed in characters on the information display unit 72a, but it can be intuitively understood by the colors displayed in the control type notification unit 72d. . In particular, since the luminescent color is the same as the background color of the road, the user can understand the type more intuitively, which is good.

[Function to issue different alarms for the same alarm target]
Even with the same type of alarm target, it is preferable that the alarm target that requires attention for passing is the specific alarm target, and the specific alarm target is easily notified of the conditions to be the alert target. The alarm target of the same type may include, for example, the same part in the name, and for example, the alarm target of "crossing" may be distinguished from the "needed level crossing" which requires the same attention as passing. The level crossings requiring attention include, for example, “crossing without opening”, “crossing with many accidents”, “car bottleneck”, “pedestrian bottleneck”, “narrow”, “school road”, and the like. For this level crossing, it is preferable to use, for example, the information on “crossroads to be improved” designated by the Ministry of Land, Infrastructure, Transport and Tourism.

  The level crossing to be alarmed is grouped into a normal level crossing and a level crossing requiring attention, and these are stored separately. For example, the alarm may be issued from a distant position by increasing the distance at which the approach alarm is started between the caution level crossing and the distance at which the approach alarm is started between normal level crossings. Furthermore, for example, when the target for which an approach alarm is issued to a normal level crossing is within a predetermined angle θ1 with respect to the traveling direction of the vehicle and the caution level crossing is θ2 (θ2> θ1), the level crossing which is more oblique In the case of a level crossing requiring attention, the alarm condition is met and an alarm is issued.

  For example, if there is a "crossing without opening" at the end of the road that is running, even if it is reported that there is a "crossing without opening" after approaching, for example, 200m, there will be no stress and there will be stress It is. So, in this form, it is made to be able to escape to another detour by alerting | reporting at an earlier timing than normal level crossing. A target icon for a level crossing that requires attention, such as a level crossing without opening, is displayed on the map of the standby screen, so the user can drive on the current road by looking at the relationship with the vehicle position, or turn left or right You can decide what you need to do and follow the appropriate path. Also, whether or not it is sufficient to go straight even if a voice message including directions such as “There is a cautionary crossing ahead XXm left” or “There is a cautionary crossing ahead XXm ahead” is added. It is good because you understand.

  The specific alarm target may have a prominent alarm mode. For example, it is preferable to change the color or change the content of the notification by voice. The notification using voice is, for example, "open level crossing, please be careful" and "accident frequent level crossing, ......" are prepared individually for the other two, "others are caution level crossing, ..." In summary, the number of alert types was reduced to be less than the types of level crossings that belong to caution level crossings. In particular, it can be understood by just listening to the voice that it is possible to know what kind of caution crossing is necessary by making “a crossing without opening” and “a lot of crossings with many accidents” which require special attention be different voice messages.

  Further, it is preferable to use one common target icon 35 displayed on the map for the six types of caution crossings, and prepare different types of CG with motion to be displayed in the alarm image display window W3. Since the target icon 35 has a small display area, it is difficult to distinguish the difference at a glance. Since the alarm image display window W3 has a display area to a certain extent, it is preferable to use different CGs to convey the contents of each level crossing in an easy-to-understand manner.

  Furthermore, it is preferable that the alarm conditions for “crossing without opening” be relaxed, and warnings should be issued early and wide, especially among “cautionary level crossings”. For example, “Accident frequent level crossings”, “Narrowness”, “Bottleneck”, and “School road” are more alert than normal level crossings, but they can be passed with caution. It takes a lot of time to pass through, so it is good to notify early. Also, for school routes, it is better to change the alarm conditions and alarm contents according to the school hours and days of the week.

[Modification]
FIG. 22 and FIG. 23 show an example of the type of each target to be alerted, the target icon, and the timing of alert / notify in the GPS alert function of alerting based on position information. The explanation displayed on the above-described explanation pop-up screen may be replaced with characters, or a figure explaining the timing for issuing an alarm as shown in the figure may be displayed.

  The user is not very aware of the timing of the alarm sound, but it is good because it can be intuitively understood and can be convincingly illustrated. Although these figures are sometimes described in the instruction manual, the linkage with the actual operation of the radar detector 1 is poor and the instruction manual is often not seen, but the radar detector Displaying on the display unit 1 is preferable because the alarm timing can be easily understood.

  Although each embodiment mentioned above presupposes one apparatus called the radar detector 1, the display of a description pop-up screen may be implement | achieved by another apparatus, for example. When realized with another device, for example, a smartphone or a communication robot may be used.

  The smartphone should be an AR app. For example, the radar detector 1 may be photographed, recognition processing may be performed based on the acquired image to specify a model, and a description for the model may be displayed. Moreover, it is good to make it alert | report by voice using AI. For example, when a question having a speech recognition function and having a term corresponding to a setting item such as "What is the LH system?" Is recognized, for example, it is preferable to answer the contents notified in the explanation pop-up by speech. In any case, it is good to have an explanation of the contents immediately when you want to know.

[History display function]
For example, the driver may be worried that, for example, "Is the speed slightly exceeded?" Conventional radar detectors have a function to display their own vehicle speed from the front of Orbis to ○ m on the display unit, but there is a problem that they can not check their own vehicle speed when passing after passing is there. For example, if the driver looks at his / her vehicle speed displayed on the display unit 4 of the radar detector 1 when passing a warning object, the driver can check the passing speed, but usually the driver looks forward while traveling Therefore, it is difficult to gaze at the display unit 4 when passing. Even if the vehicle speed displayed on the display unit 4 is viewed, it is only necessary to check the vehicle speed at the pinpoint position, and thus the trend of driving trends such as changes in driving conditions and speeds. There is also a problem that is difficult to understand.

  The radar detector 1 has a function of recording information on the vehicle speed when passing a predetermined alarm target, and a history display function of notifying the display unit 4 of history information of the recorded vehicle speed. The predetermined alarm target may be, for example, a speed measuring device that measures the speed of the vehicle, and particularly a vehicle speed measuring device that is fixedly installed.

  For example, not only places where vehicle speed measurement devices such as Orbis are fixedly installed, but also places where mobile speed control is performed, such as control areas, etc. It is a dangerous place where traffic accidents are likely to occur, and it is often necessary to drive safely without exceeding the speed. If the alarm targets for recording the history information of the vehicle speed among the alarm targets for the GPS alarm are limited to them, when the recorded history information is confirmed later, the self in particular at the point / area where the safe driving should be performed It is good because you can efficiently check the driving trend of. In particular, the location where vehicle speed measurement devices such as Orbis are fixedly installed is the point where the traveling speed should be more careful than in the control area, so the function to record and notify only the alarm object such as Orbis It is good to have

  The “when passing the alarm target” for recording the speed of the host vehicle may be, for example, within a predetermined section from when the alarm target passes and from Xm before the alarm target to Ym after passing. In this embodiment, since the information regarding the own vehicle speed is recorded, the own vehicle speed when passing through a predetermined alarm target can be confirmed. Since the own vehicle speed in a predetermined section from Xm before the alarm target to Ym after passing is recorded, it is possible to notify the traveling condition of the own vehicle speed not only at the time of passing but also around it. During this predetermined section, the control unit 18 acquires and records the own vehicle speed obtained based on GPS information at appropriate timing and the “vehicle speed” included in the OBD information, and displays a list at a predetermined timing. And displayed on the display unit 4 as

  If the vehicle has a function of taking and displaying a plurality of vehicle speed histories in a section from the front of the alarm target to the target of the alarm, the driving tendency may be known. For example, when the alarm target is a speed measuring device such as Orbis, the driving trend of decelerating the speed below the speed limit immediately before the alarm target is undesirable and dangerous. For example, if only the vehicle speed at the time of passing is notified, the vehicle decelerates just before and becomes less than the speed limit at the time of passing, and when traveling at a speed less than the speed limit from a relatively far side The result is a normal result of “passing below the speed limit”, and the previous dangerous driving trend cannot be detected. On the other hand, in the present embodiment, by recording and displaying the history of the speed from the near side of the predetermined distance of the alarm target, it is possible that the vehicle is run unfavorably for safe driving such that the speed is dropped immediately before the alarm target. It is good because it can be detected and alerted.

  For example, a driver who sees his / her vehicle speed in the displayed specified section “delivers safe driving at always lower than legal speed from the near side”, “decelerates as it approaches, such as immediately before the alarm object from the overspeed state. As we know tendency of one's operation such as "we decelerate speed after alarm, and keep below legal speed" and "do not decelerate even if we receive alarm", we call attention when we drive after that So it ’s good. Further, even after passing through the alarm target, if a function for recording and displaying a speed history for a certain period is provided, the driving tendency after passing may be understood. If you record and display your own vehicle speed in the section to Ym after passing in addition to passing etc., for example, "We are driving safely at below legal speed even after passing", "We accelerate immediately after passing and overspeed The driver's tendency etc. can be understood objectively because it is not good because driving tendency that understands such as “I do” and accelerates immediately and overspeeds is not good. good.

  Xm and Ym may be the same or Xm should be longer. If the alarm target is a fixed installation type speed measuring device such as Orbis, the installation position is selected as a place that is dangerous and needs to be safer, such as a place where it is likely to exceed the speed or a traffic accident is likely to occur. There are many things. For this reason, it is not preferable in terms of safe driving just to reduce the traveling speed below the legal speed at the time of passing through or immediately before the speed measuring device to be alarmed, and it is necessary to reduce the speed from the front. Therefore, X should be set to a relatively long distance, and it is better to record and notify from a relatively far position.

  On the other hand, for example, an operation that accelerates immediately after passing a speed measuring device and exceeds the speed is not preferable for safe driving, for example, and such driving trend is relatively compared to the front Xm of the alarm object such as the speed measuring device. As it appears in a short distance, Y can sufficiently grasp the driving trend in a short distance compared to X. Y = X or Y> X may be used, but in such a case, a large memory capacity for recording the speed history information is required, so if X> Y as in this embodiment, a sufficient memory is required. The capacity may be used to appropriately record and report driving trends in the sections before and after the alarm target.

  It is preferable that X be a relatively long distance, for example, a distance corresponding to a predetermined distance in front of an alarm target to be notified by voice. The corresponding distance may be a fixed interval before and after the alarm target to which the voice notification is given, and the fixed interval may be a close distance such as immediately before or immediately after, particularly, the same. In this way, for example, it is possible to understand the traveling state after the voice notification such as decelerating based on the voice notification to set an appropriate running speed, and continuing high-speed traveling without decelerating even when receiving the voice notification. It is good to know if the alerting is functioning effectively for the driver.

  The predetermined distance for voice notification is, for example, 500 m, 1 km, 2 km, etc., but is preferably 500 m. When the alarm is issued a plurality of times, the immediately preceding alarm is the most important, and the effect of the alarm by the most important immediately preceding voice notification is good. Furthermore, if a point where a warning object such as a speed measuring device is installed is a dangerous section, for example, the section where a speed is likely to be exceeded over a long section such as 1 km or 2 km ahead Rather than being a place where safe driving needs to be kept in mind, a predetermined section close to the point at which the alarm target is installed is a section where special attention should be paid to safe driving. Even in view of this point, Xm may be set to 500 m as in the present embodiment. If it is 1km or 2km, if the section up to the alarm target is recorded regularly, the data capacity will be large. For example, it is not preferable from the relation of the memory capacity of the memory card. It is good because it has merit.

  The control unit 18 having a history display function of the own vehicle speed and the like according to the present embodiment acquires the own vehicle speed for every predetermined distance during the recording zone of the own vehicle speed from the near Xm of the predetermined alarm target to Ym after passing. And record. For example, the predetermined distance may be 100 m. In the present embodiment, for example, X = 500 and Y = 100, so the vehicle speed is acquired at intervals of 100 m for sections from 500 m before and 100 m after the alarm target and stored in one file. . The control unit 18 may also have a function of acquiring information related to driving and traveling, recording the information in association with the speed of the vehicle, and notifying the information. The related information may be, for example, travel date / time information, GPS radio wave reception status, information for identifying the road on which the vehicle is traveling, a photograph of a live-action warning, a speed limit, a type of alarm target, and the like. By recording the relevant information and displaying the relevant information at the same time with the company speed acquired when displaying the speed history, it is possible to determine whether or not the driving was appropriate from the history of the own vehicle speed. You can do it properly. For example, when the vehicle speed is determined based on GPS radio waves, recording the reception condition of the GPS radio waves may be a guideline for the reliability of the calculated vehicle speed. For example, when the reception condition of the GPS radio wave is good, the reliability of the recorded own vehicle speed becomes high, and when the reception condition is bad, the reliability becomes low. In addition, for example, by recording the speed limit and displaying the speed limit and the vehicle speed at the same time, it is possible to intuitively understand whether or not the vehicle is traveling below the speed limit and the degree of opening with respect to the speed limit.

  The control unit 18 causes the display unit 4 to display the history of the vehicle speed in the recording section recorded when the recorded predetermined alarm target is passed at a predetermined timing. In the present embodiment, a self-vehicle speed of 100 m after the passage is displayed in a list from 500 m before the passage, so a user such as a driver who saw it can know at a glance whether or not he is in violation of the speed. For example, the driver can know the tendency that the speed has increased or decreased from this area, and the relative speed with respect to the speed limit. Can do. For example, if you pass Orbis with speeding, you will be notified later by the police station, but it may take several months before the notification comes. The driver who notices the presence of Orbis after passing Orbis can check the travel history using the history display function, and can take an indication of whether or not he has violated the speed, and will the notification actually come? It can alleviate the effort for several months.

  The recorded history information such as the vehicle speed may be displayed using, for example, the second menu screen without immediacy described above. As described above, for example, the control unit 18 that detects that the standby screen is touched switches the display of the display unit 4 from the standby screen to the first menu screen shown in FIG. One menu screen is displayed on the entire display screen of the display unit 4. When it is detected that the setting button 41c in the first menu screen is touched in that state (see FIG. 5B), the control unit 18 is the top screen of the second menu screen shown in FIG. 5C. The setting menu screen is displayed on the entire display screen of the display unit 4. When the function button 42b in the setting menu screen is touched, the control unit 18 displays the first page of the function setting screen shown on the left side of FIG. In the embodiment described above, in the four setting item display areas 43b of the second page of this function setting screen, two of “Sound custom” and “Screen reverse” are used, and the lower two are blank. As shown in FIG. 25A, the function setting screen on the second page has a layout provided with setting items for history display. In the illustrated example, “Orvis passage history” is displayed on the title display section 43b ′ of the third setting item display area 43b from the top, and the setting content display section 43b at the right end of the third setting item display area 43b. In the present embodiment, the alarm target for recording the passage history such as the vehicle speed is the speed measuring device fixedly installed like Orvis so that the alarm target can be clearly understood. It is written as "passing history".

  When it is detected that the setting item display area 43b of the “Obisu passage history” is touched, the control unit 18 displays an Orbis passage history list list screen as shown in FIG. The layout of the Orvis passage history list list screen is the same as that of the function setting screen and the like. A title display portion 46a is arranged at the upper end, and a large number of areas below the title display portion 46a are used to make a plurality of passage history lists. A predetermined number of display units 46b are arranged vertically, cursor buttons 46c are arranged above and below the right end, a page display unit 46d is arranged at the center of the right end, and buttons 46e and top buttons 46f are arranged below the left end Take a layout to do. The title display unit 46a displays "Obis passage history" indicating that it is a passage history list.

  As described above, the passage history list display unit 46b adopts a layout in which four are arranged vertically. The control unit 18 acquires passage date and time information and the like of the recorded passage history, and displays the date and time information and the like on the passage history list display unit 46b in order from the latest passage date and time information. If there are five or more recorded passage histories, the control unit 18 forms a plurality of Orvis passage history list screens and displays the first sheet. In response to the touch of the cursor button 46c, the control unit 18 switches the screen.

  The passage history list display unit 46b displays the passage date and time, information specifying the type of alarm target, and information indicating the speed limit at the installation location of the alarm target in a horizontal row. As for the passage date and time, day information may be added as shown in the figure. By adding the day of the week information, it is easy to remember the memory of when or which user the user passed. The information for specifying the type of alarm target uses a target icon drawn on the map screen at a location corresponding to the installation position of the alarm target on the map. By using the target icon, the type of alarm target can be understood at a glance. In the example shown in the figure, the mark "LC in white in red circle" showing the loop coil in order from the top, "Mark LH in white in red circle" showing the LH system, radar formula including small orvis Marks of “white RD in a red circle” are displayed. The speed limit information of the installation site of the alarm target is a mark corresponding to the traffic sign of the speed limit. In the illustrated example, the speed limits of 110 km / h, 100 km / h, and 80 km / h are displayed in order from the top.

  When displaying the list of each passage history on the passage history list display unit 46b, the control unit 18 may display the list in a manner different from that in the normal case, for example, when there is an unfavorable driving trend such as exceeding the speed limit. Different aspects may be prominent aspects. If the mode is conspicuous, it may be possible to recognize that an unfavorable operation is being performed in terms of safe driving such as exceeding the speed limit without overlooking it. The noticeable aspect may be, for example, a prominent color, and for example, date and time information may be displayed in red. In the illustrated example, the date, day of the week, and time of the second “2017/12/22 (Friday)” from the top are displayed in red. For example, as a different mode, part of the date, day of the week, and time may be changed to a different mode such as red, or the outer frame of the passage history list display unit 46b may be displayed with a red line, for example, line 44h of FIG. Although a line may be displayed below the date and time information, etc., as in the present embodiment, the date and time can be made more noticeable by making the character part in red, and in particular, the date, the day, and the time may be displayed. It is good because it makes it more noticeable by making all of the red.

  When it is detected that the passage history list display unit 46b is touched, the control unit 18 reads out information regarding the touched passage history and displays a detailed information display screen shown in FIGS. 25 (c) and 25 (d). The control unit 18 reads and displays information related to the vehicle speed at each point and the driving / running stored in association therewith on the detailed information display screen. In the display layout of the detailed information display screen, the date and time information display section 47a, the road specific information display section 47b, and the own vehicle speed information display section 47c are arranged in order from the top in the area on the left side of the screen, and the area on the right side of the screen. In order from the top, the GPS radio wave reception status display unit 47d, the moving direction display unit 47e, the live-action image display unit 47f that displays the real image of the alarm target that has passed, and the alarm target type information display unit 47g that displays the type of alarm target A speed limit information display unit 47h for displaying speed limit information of a point to be alerted is disposed. An SD output button 47i is provided below the alarm target type information display unit 47g and the speed limit information display unit 47h, and a QR code (registration) is provided to the left of the alarm target type information display unit 47g and the SD output button 47i. A layout for displaying a two-dimensional code 47 j such as a trademark is taken.

  The date / time information display unit 47a displays the date / time information displayed on the passage history list display unit 46b. The road specific information display unit 47b displays road specific information for specifying the road on which the vehicle has traveled, and outputs, for example, an address and a road name simultaneously in the vertical direction. There are people who remember road names well, so by outputting the address and road name at the same time, the driver records where the Orvis passage history is displayed and where it is traveling This makes it easier to recognize whether the information is correct. If a specific place can be identified and recognized, for example, if the vehicle is overspeeding, it is possible to be aware that it is necessary to pay attention to excessive speed when driving on the same road / place at a later date.

  The host vehicle speed information display unit 47c displays host vehicle speed information at each point from, for example, 500 m to 100 m after passing, and for example, the recorded host vehicle speed is sequentially from the distant position of the alarm target Display side by side from the top. Since the vehicle speed is arranged vertically in the order of vehicle movement, the user who sees it can easily understand the situation of the speed change as it approaches the alarm target orbit, whether there is a speed change after passing, etc. Good.

  If the vehicle speed recorded is a predetermined speed over the speed limit, it may be displayed in a display mode different from the others. A display mode different from the others may be a conspicuous mode. The noticeable aspect may be realized by a simple configuration, for example, when displaying in a prominent color. The conspicuous color may be red, for example. The color changing part may be the entire speed and unit part, for example, “XX km / h”, but the display color of only the numerical part of the speed is changed as in this embodiment, for example, It is better not to change the unit such as km / h. By changing the color of only the numerical part of the speed, it is better because the numbers are more noticeable and it is possible to know that the speed is exceeded and the actual speed.

  For example, the predetermined speed is changed to 0 km / h when the speed exceeds the speed limit, or the predetermined speed is set to 1 km / h, and the display is changed when the speed exceeds the speed limit so that it does not change when the speed limit is exactly the same. However, it may be a constant speed with a predetermined margin. The constant speed with a predetermined margin may be set to a speed that can be a dangerous traveling speed due to excessive speed, for example. By displaying only overspeeds that are particularly dangerous driving speeds in a conspicuous color such as red, you can see at a glance that there is driving that greatly exceeds the speed limit if there is such a conspicuous color display, It is good because you can call attention to safe driving. The constant speed with a predetermined margin is preferably 20 km / h, for example. Speed over 20km / h is very dangerous. For example, it is not a phenomenon that occurs when you accidentally step on the accelerator a little or increase the speed slightly on the downhill. Arouse it.

  Running speed exceeding the speed limit is not preferable for safe driving, but it is hard to say that it will suddenly become dangerous if the speed limit is slightly exceeded, for example 1 km / h, compared to when driving at speed limit, for example. For example, when traveling stably around the speed limit, the speed of the vehicle may momentarily exceed the speed limit slightly from the road conditions such as downhill, etc., and the speed of the vehicle when it slightly exceeds It may be recorded. In such a case, if it is displayed in a color that stands out as speed limit over, it is difficult to tell at a glance whether it was a very dangerous operation of 20 km / h or more as described above or a drive slightly over the speed limit. However, it is not possible to efficiently notify that there is a dangerous drive, and in some cases, there is a risk that the dangerous drive history may be buried in a history that slightly exceeds the speed near another speed limit. In this embodiment, only those with 20 km / h or more of extremely high speed and dangerous driving are displayed in different colors such as red, so that the dangerous driving history can be surely recognized by the user. So good. The predetermined speed may have a larger margin such as 30 km / h, for example. If it is too large, dangerous driving less than that may easily be overlooked, so 20 km / h as in this embodiment may be used.

  Since the reception status of the GPS radio wave is displayed simultaneously with other information on the reception status display unit 47d, when the travel speed is obtained based on the GPS radio wave, for example, when the reception status is good, the displayed travel speed is displayed. It is good because you can understand that the historical information is reliable and reliable. For example, if the reception conditions are good and all displayed traveling speeds are less than the speed limit, it can be seen that the section where the passage history was obtained was safe driving without violating the speed, exceeding the speed limit If you do, you can be convinced that you have violated your speed. If the reception status is poor, the reliability of the recorded and displayed vehicle speed is low, so it is difficult to claim that the vehicle is not violating the speed even if the temporarily displayed vehicle speed is below the speed limit, For example, when a speed violation is recorded for an orvis with the passage history, the user can easily give up.

  The image data displayed on the photographed image display unit 47f may be a photographed image displayed on the alarm image display window W in front of the alarm target that has passed. By displaying the live-action image, the user who sees the image can more intuitively recognize which alarm data such as Orbis has passed through the history data.

  When it is detected that the SD output button 47i is touched, the control unit 18 creates a text file in which the displayed detailed information is recorded, and performs a process of outputting the text file to the memory card 11. The file name of the text file may include, for example, date and time information.

  The two-dimensional code such as QR code (registered trademark) may be, for example, a two-dimensional code including information specifying an alarm target displayed on the detailed information display screen. Information for specifying an alarm target may be, for example, position information, speed limit, or the like. For example, when the two-dimensional code 47j is photographed using a portable device equipped with an application that reads a two-dimensional code, such as a smartphone, the application displays information recorded in the two-dimensional code 47j on the display unit of the portable device. By looking at the content displayed on the display unit on the portable device, the user can know information on an alarm target such as Orbis related to the traveling history displayed at his hand. Usually, since the display screen of the display part of portable devices, such as a smart phone, is larger than the display part 4 of the radar detector 1, the contents can be easily confirmed and easily confirmed. In particular, the information for specifying the alarm target may be a two-dimensional code including information for specifying a point where the alarm target is installed and information for accessing a map site on the Internet. The information specifying the point may be, for example, longitude and latitude information. For example, by using a mobile device equipped with an app that reads a two-dimensional code such as a smartphone, the map site is accessed by photographing the two-dimensional code 47j, and the installation location of the alarm target is displayed on the map on the display unit of the mobile device. Display so that you can see where it is. In this way, the user can more accurately recognize where the alarm target is, and can be alerted to drive with caution when traveling on the installed road.

[Modification of history information display function]
In the above-described embodiment, whenever passing a predetermined alarm target, history information such as the vehicle speed is created and recorded, and date and time information is sorted using a key to display a list list. For example, when the controller 18 records a series of information such as the vehicle speed acquired with the passage of a single alarm target, the information about the same alarm target is recorded in association with each other. It is more preferable. In association with the recording, for example, a holder may be created for each alarm object, and may be recorded in the passed alarm object holder. If there is an alarm target such as Orbis, which passes each time, the control unit 18 groups and stores the acquired information such as the vehicle speed in the same holder. In this way, the same alarm object such as the same orth and so on can be easily compared with the history information acquired when passing in the past. The same alarm target is a different alarm target when the installation location is different. For example, when the alarm target is a speed measuring device such as Orbis, it may be distinguished as one alarm target for each speed measuring target. However, it is more preferable that, for example, a plurality of speed measurement devices installed on roads having the same road name be the same alarm target. In particular, motorway roads such as expressways are divided into certain areas such as prefectures, for example, and multiple alarm targets installed in the same motorway road are located in one group as the same alarm target. It is good to register for.

  In the modification, when the setting item display area 43b of the "Orvis passage history" is touched on the function setting screen shown in FIG. 25A, for example, the Orbis passage history list list screen for each alarm object is displayed. The Orvis passage history list for each alarm object has the same layout as the Orvis passage history list screen shown in FIG. 25B, for example, and specifies the alarm object for the content to be displayed on the passage history list display part 46b. It should be information to do. The information for specifying the alarm target may be, for example, a road name, an address, or the like. The information for specifying a plurality of alarm targets arranged vertically is preferably arranged in order from the alarm target that has passed most recently (see FIG. 26). When it is detected that the display unit for displaying the information for specifying the alarm target is touched, the control unit 18 displays the Orvis passage history list shown in FIG. 25 (b), and displays in each passage history list display unit 46b. It is preferable that date and time information and the like of passage history information belonging to the touched alarm target group be displayed.

[Modification of velocity recording]
In the embodiment and the modification described above, each time a predetermined alarm target is passed, speed history information associated with the passage is created and recorded, and displayed at a predetermined timing. Instead of recording all the information in this way, for example, the passing history of the own vehicle speed may be stored when the speed exceeds the predetermined speed by a predetermined speed or more and not stored when the speed is lower than the predetermined speed. . The predetermined speed may be stored, for example, as 0 km / h or more when the speed exceeds the speed limit or when the predetermined speed is 1 km / h when the speed limit is exceeded, but, for example, 20 km / h or 30 km / h It is good to set the speed which took a predetermined margin in In this way, the number of histories to be stored can be reduced, and it is possible to solve the problem of being bothersome if, for example, there are frequently passing orbiss, they are recorded each time and remain in the history. In particular, we usually know the location of the Orbis that passes well, and tend not to exceed the speed, and when such data that does not exceed the speed remains in the history and is displayed in the list, the history you want to see is found. Although it becomes difficult, in this embodiment, occurrence of such a situation can be suppressed. It is preferable to save dangerous driving with history as a history and to call attention by storing only those with a high level of over-speed taking a predetermined margin.

  Also, alarm targets not storing history may be registered as points, and those registered may not be left in the history, but as in the above-mentioned modification, it is better to save only when the predetermined speed is exceeded. More preferred. For example, even if you usually drive well and know the existence of the alarm target and drive to keep the speed limit, for example, there is a risk of inadvertently exceeding the speed, and in the above modification, when the speed is exceeded. Is preferable because it can store a history.

[Modification of display timing]
The display timing of the recorded history information is, for example, the passage history of the alarm target when the power of the radar detector 1 is turned on or when the predetermined distance before the predetermined alarm target such as Orbis is reached. If a detailed screen of the travel history is displayed when the predetermined distance before the alarm target is reached, a warning to safe driving can be performed efficiently and appropriately. For example, if the detailed information of the past passage history displayed at the same location exceeds the speed, it will exceed the speed in the same way as driving the driver as it is because the road has been overspeeded in the past. It may be possible to recognize and warn that it is necessary to travel with the speed slightly decelerated.

  If there is more than one passage history information to be displayed when the power is turned on or before the alarm target, for example, the latest one may be displayed, but when displaying a bad passage history with a large excess speed, alerting to safe driving Is more preferable.

  As described above, the display timing may be automatically displayed in accordance with the condition matching, but it is preferable to be performed based on a user operation based on a screen touch or the like as in the embodiment described above. When displaying based on user operation, the driver who is a user has a consciousness of checking the detailed information of the passage history and confirms it. The driving trend of the speed change in the vicinity can be confirmed, and it can be triggered by the subsequent safe driving.

[Modification 1 of reflection to alarm]
According to the contents of the passage history, it is preferable to have a function of performing different alarm contents before the alarm target. For example, when issuing a warning at a predetermined distance before the alarm target, the control unit 18 may perform a warning stronger than a normal alarm when there is a passing history that is not preferable for safe driving such as overspeed for the alarm target. . For a strong alarm, for example, the timing of emitting the alarm may be performed from a distance farther than usual, the contents of the alarm may be changed, the notification mode may be changed, and a plurality may be combined. When changing the content of the alarm, for example, change the content of the voice notification performed before the predetermined distance to a normal thing and give a content of a strong word that can prompt attention, or a notification that prompts attention in addition to the normal alarm . When changing the notification mode, for example, it is preferable to switch from a notification mode using only one of an alarm using a voice and an alarm using a display unit to a notification mode using both.

  The content of the passage history that serves as a reference for performing a strong alarm may be, for example, that there are cases where the reference speed simply exceeds the reference speed according to the speed limit. It is even better to differ the mode of the strong alarm depending on whether it exceeds. The reference speed corresponding to the speed limit need not necessarily be equal to or higher than the speed limit, and may be set to a predetermined speed less than the speed limit. For example, when the vehicle is traveling at a speed close to the speed limit even if the speed is lower than the speed limit, for example, if the accelerator is depressed slightly, the speed limit may be exceeded and an accident may occur in the future. If the reference speed is set to a predetermined speed slower than the speed limit, when driving at a speed close to the speed limit, an alarm / plus alpha warning that alerts the user when driving next time can be issued.

  For example, for a road with a speed limit of 100 km / h, if the reference speed is set to 90 km / h, for example, if a speed of 90 km / h or 100 km / h is recorded in the passage history, You should be alerted by a special voice alert such as "Let's drive at the very end, let's drive with caution," and let it slow you down. The location where the vehicle speed measurement device such as Orvis is installed is a place where speed is likely to occur and an accident is likely to occur. It is good because it is deterred in advance.

  Also, in the case of providing a plurality of reference speeds, if the reference speed becomes faster, a warning to be issued later than that will be warned with a more emphasized phrase, for example, to promote safe driving below the speed limit. good. When a plurality of reference speeds are provided, at least one may be set lower than the speed limit, and at least one speed may be higher than the speed limit. In this way, the warning to the Dangerous Reserves who are not overspeeding but may overspeed in the future, and the warning to drivers who are actually overspeeding and are driving dangerously are respectively matched. It is preferable to warn the driver of each driving trend by providing an appropriate warning for safe driving.

  The content of the passage history serving as a reference for performing a strong warning may be determined from the trend of changes in the vehicle speed recorded in a plurality of past passage histories. For example, the speed limit of 110 km / h passed at 100 km / h last time, but this time, for example, the vehicle speed recorded most recently increased and exceeded the speed as if it passed at a speed close to 110 km / h. If it is in the direction, it is preferable to give an alert to warn when traveling on a road on which the same alert object is installed next. For example, if you receive a warning on the road you are driving for the first time, you will decelerate and pass at a speed that is sufficiently slower than the speed limit, but you will gradually get closer to the speed limit as you drive several times, However, there is a possibility that the speed will be exceeded soon, but as mentioned above, it is better to give a warning alert in advance if there is a tendency to prevent such a situation from past past history. .

  A strong alarm may be changed to a voice notification, and after displaying a "detailed screen for a predetermined passage history", a normal warning may be issued, and in particular, a notification to display the detail screen in addition to the prominent voice notification Because it becomes a stronger alarm, it is good.

[Modification 2 of reflection to alarm]
It is preferable to provide a function for performing different alarms depending on past driving conditions. The past driving condition is not limited to the passing history of the vehicle speed for a predetermined alarm target such as Orbis as described above, and for example, a point where the predetermined speed is exceeded for the speed limit is recorded, and thereafter When passing through the point, a predetermined warning may be issued before that point.

  Further, the traveling state may be rough driving, for example. Rough driving includes, for example, sudden start, rapid deceleration, and sharp curve, and may be determined based on the output of an acceleration sensor mounted on the radar detector 1, for example. The control unit 18 records the point at which the rough driving has been performed, and warns before the recorded point at the time of the subsequent driving. The radar detector 1 according to the above-described embodiment or the like has a GPS alarm function for storing position information of a specific alarm target and alarming from the GPS information in front of the alarm target, but a dangerous place based on the driving situation of the user It is desirable to have a function to add points and to issue a warning even to the added dangerous place points.

[Modification of alarm presence / absence setting function]
It is preferable to have a function of actively changing the alarm performed before the alarm target in accordance with the driving trend of the user. For example, a place that is always driving at a safe driving speed or less may be warned less than usual. Unobtrusive alerts may include those that do not alert, but weak alerts may do. If you do not warn you, you may misunderstand that there is a risk of failure or you may accidentally exceed the speed limit even if you are running below the speed limit, so by giving a weak alarm you will not cause such misunderstandings etc. So good. In this way, even for the same type of alarm target, it is possible to give a normal alarm or an inconspicuous alarm according to the driving trend of the user, and make the alarm necessary for the user appropriate Good because you can.

  For example, there are many types and numbers of alarm targets that perform GPS alarms, and depending on the area where the vehicle travels, alarms may be issued frequently, so even if there are important alarms, they may not be noticed. Such a problem becomes more noticeable when a point is issued to issue an alarm based on the travel history information of each user as in the above-described modifications and the like. In order to reduce the number of times of alarm occurrence, for example, it is possible to respond by selecting [mode] of the setting item display area 43b of the function setting screen and switching ON / OFF of the alarm for each type of alarm object by setting the mode. In particular, in the manual mode, ON / OFF can be set individually for each type of alarm target. However, such a mode setting is complicated, and many users use it as the initial setting after all, and as a result, the radar detector frequently emits an alarm and feels loud, and may get used to the alarm and miss an important alarm. However, an appropriate alarm can be issued according to the user's travel, and the related problem can be solved.

[Drive recorder link]
It is preferable to have a function of linking the radar detector 1 and the drive recorder, and recording moving image data of a predetermined section when passing a predetermined alarm target. The control unit 18 of the radar detector 1 transmits a trigger signal to the drive recorder when passing a predetermined alarm target such as Orbis. In response to the reception of the trigger, the drive recorder records an image of a predetermined time before and after the passage of the alarm object such as Orbis. The predetermined time may be, for example, 15 seconds on the near side, and 5 seconds after passing, for a total of about 20 seconds. The drive recorder has a continuous recording function for capturing and recording a continuous recording, and an event recording function for recording a moving image of a predetermined period before and after a predetermined event occurs. In the present embodiment, it is preferable that reception of a trigger from the radar detector 1 be an event occurrence time, and an image of a predetermined time before and after passage be acquired and recorded by an algorithm similar to the event recording function. For example, it is difficult for the drive recorder to record on the basis of the distance as in the case of mm in front of the alarm target, and the recording may be easily performed by using the time as the reference as in the present embodiment.

  The drive recorder has a holder for recording a constant recording and a holder for recording an event, and stores each video data in each holder. In the present embodiment, a holder called “Obis” is created (see FIG. 27A and the like), and when the Orbis passes, a file of video data before and after the pass is created and stored in the Orbis holder.

  By managing the passing history information with the captured moving image, it is preferable to confirm the traveling condition such as the weather at the traveling time or the surrounding vehicle condition. For example, it is possible for the driver to easily understand the correlation between the traveling condition and the traveling speed, etc. For example, it is possible to improve the driver's level of understanding and create a situation where he can be conscious of safe driving.

  Orbis holders are preferably created for each Orbis as a lower holder. The video data created when passing through the same Orbis is grouped and stored in the same lower holder. The user can confirm the image data of the same orb by opening the holder of a predetermined orb, and can easily compare with past passage history information. For example, in the past, the vehicle may exceed the speed limit or may travel near the speed limit by comparing and checking multiple travel data and video data when passing through the same Orbis etc. When it turns out that such an event occurs at a specific weather, such as a sunny day, and when traveling on other days with a margin for the speed limit, then when driving on a sunny day It is good because you can be especially aware of safe driving.

  The history information recorded along with the passage of a predetermined alarm target is recorded, for example, in the memory card as in the other constant recording and event recording. When viewing the history information, for example, it is preferable that the memory card be taken out and be set on a personal computer or the like and read out from a predetermined file to reproduce the information on the personal computer. In such a case, if the holders are divided into alarm objects as described above, the user may easily find history information when passing through the desired alarm object.

  For example, it is preferable to provide a function of displaying the recorded video data on the display unit of the radar detector 1. Such a function is preferable because it can be confirmed on the spot in the vehicle without being set in a personal computer or the like as described above. The reproduction of the video data is controlled, for example, by setting the reproduction button area of the video data in the detailed information display screen shown in FIGS. 25C and 25D and detecting that the reproduction button area is touched. For example, the unit 18 may obtain video data of the traffic history displayed on the detailed information display screen from the drive recorder and reproduce it. For example, a special button area such as an SD output button may be separately set as the playback button area. However, such a special button area is not separately set, and other information such as a live-action image 47f is displayed. It is particularly preferable to allocate a reproduction button area to the processing area, and to acquire and reproduce related video data when, for example, a portion of the photographed image 47 f is touched. This combination is preferable because it is not necessary to separately secure an area for the reproduction button area, and a wide area for displaying information such as the own vehicle speed can be secured. In particular, as exemplified above, when the display area of the photographed image 47f is also used as the reproduction button area, the reproduction of the image may be intuitively understood and recalled.

  As described above, the detailed information display screen of the passing history of each vehicle speed is linked to the function of reproducing video data by linking, or in addition to the function concerned, a direct image separately from the passing history of the vehicle speed It is preferable to have a function of reading and reproducing data. For example, when the function button 42b in the setting menu screen which is the top screen of the second menu screen shown in FIG. 5C is touched, the control unit 18 is shown on the left side of FIG. It is preferable that the first page of the function setting screen is displayed, and the page of the function setting screen displayed with the touch of the cursor button 43c has a layout as shown in FIG. 27B, for example. In the function setting screen shown in FIG. 27B, a button area for reproducing video data "Ovis passage history (video)" is set in the fourth setting item display area 43b. When the control unit 18 detects that the fourth setting item display area 43b is touched, the control unit 18 displays an Orvis passage history list list screen for video data as shown in FIG. 27C, for example. In this example, an example in which the road names are grouped and recorded is shown. If the groups are not grouped, the control unit 18 may display a passage history list similar to that shown in FIG.

[Function to record video data on the radar detector side]
In the embodiment and modification described above, when displaying and reproducing the video data of the passage history on the display unit 4 of the radar detector 1, the control unit 18 acquires and reproduces the video data recorded in the drive recorder. However, for example, the video data may be stored in advance in the storage unit of the radar detector 1, and the control unit 18 may reproduce the video data stored in the radar detector 1.

  For example, the radar detector 1 and the drive recorder are separate and cable-linked types, each having a memory card such as an SD card. When the control unit 18 of the radar detector 1 reaches a predetermined alarm target position, the control unit 18 requests video data such as a moving image and an image from the drive recorder. When the drive recorder accepts such a request, for example, the drive recorder transmits video data for a predetermined time before and after the acceptance. The control unit 18 may record the sent video data on the memory card 11 of the radar detector 1. In this way, the drive recorder only needs to record general continuous recording / event recording on its own SD card, and does not need to record the video data of the passage history to be alarmed. For example, the continuous recording of the drive recorder is erased by overwriting, and the storage capacity for event recording may become full and cannot be additionally stored. However, by storing in the memory card 11 of the radar detector 1 each time it passes, Even if a situation occurs in which the drive recorder is overwritten and erased or the recording capacity cannot be recorded, video data of the passing history to be alarmed can be recorded.

  The control unit 18 may record the acquired video data in the memory card 11 as it is. For example, it is preferable to create and record a plurality of files of photographic images in time series like a snapshot from the video data. By doing this, it is preferable that the capacity is also small and video data of a large number of passage histories can be recorded.

  The reproduction timing of the video data may be, for example, when passing the place next time. For example, when the current position of the vehicle reaches a predetermined distance before the alarm target, the control unit 18 accesses a holder that records the video data of the passage history for the alarm target, and reads out the previously recorded video data, if any. Then, the image is displayed on the display unit 4 of the radar detector 1. In this display, a message such as “Landscape from the previous run” may be displayed as a telop on the voice or the display unit 4. In this way, the video data from the previous alarm target will be played back, so drivers etc. will be reminded of the previous driving / running situation by watching the video and alert the driver this time. Good because you can. When displaying past video data in front of the alarm target, it is close to the alarm target from time to time while traveling, so the time to read and play is short, but the video data recorded on the radar detector 1 is By using it, desired video data can be instantly read out and reproduced. If you try to use the video data recorded on the drive recorder, it takes time to acquire the video data from the drive recorder and cannot be played back at the desired point, or the past video data is lost due to overwriting on the drive recorder side. However, if the video data recorded in the radar detector 1 is reproduced, there is no such problem.

  The passage history information of the video data recorded in the drive recorder, for example, stores information on the speed limit of each road in the radar detector 1, and triggers the fact that the predetermined speed is exceeded with respect to the speed limit. Although an image may be recorded, it is preferable to use a passage of a predetermined alarm object such as an orbit as a trigger as in the above-described modification. When a video is recorded triggered by exceeding a predetermined speed, it is difficult for the user to recognize where the location is, even if the video is played back, and passing history information that can not contribute effectively to the safe driving thereafter increases. In particular, since it is not preferable that passage history information such as Orvis that should be noted with safety should be difficult to search, it is preferable to limit the recording of video data to a predetermined alarm target.

  Recording of the video data may be performed, for example, based on the appearance and the trend in the vehicle based on the occurrence of an event that should be recorded outside the vehicle due to a change, an abnormality, or an emergency. For example, it is preferable to use sound information such as a change in sound outside the vehicle or in the vehicle, as the appearance / trend in the vehicle. For example, occurrences of abnormalities / abnormalities / emergencies outside the vehicle may occur when wild boars, deer, monkeys or other animals jump out of the field in the mountains, or when they are driven in a tilted manner. For example, when an animal jumps out, the vehicle collides with the vehicle and damages the vehicle, or if the vehicle is driven in a tilting manner, an accident or a passenger traveling in the tilting vehicle gets off and approaches the vehicle. May lead to the occurrence of such a situation. When the impact on the vehicle due to an accident or collision is large, the acceleration sensor detects the collision, and the drive recorder can record the event data based on the detection and record the video data before and after the collision. In the case of a weak impact, a collision can not be detected by the acceleration sensor, and an event can not be recorded, and only recording is always performed. Then, there is a problem that when the video data recorded constantly is overwritten, the video which has collided can not be stored.

  Sound information which is an example of the appearance / trend in the car is, for example, words indicating the appearance of animals such as children's cheers and noises, "Wow ○ ○ ○", "○ ○ appeared", etc. It may be a tuned voice such as “ The control unit 18 may record the video data, triggered by, for example, the frequency or level of a sound corresponding to cheering or loud noise, or the appearance of a predetermined keyword based on speech recognition.

  For example, the determination processing based on audio information may be performed on the drive recorder side, for example, for video recording of the situation at the time of occurrence of an accident, but history data at the past passage is displayed on the display unit 4 of the radar detector 1. In the case of displaying, for example, a microphone is built in the radar detector 1, the control unit 18 performs the determination processing based on the output of the microphone, and when the conditions are satisfied, video data of the sections before and after that are It is good to acquire and to record on own memory card 11.

  For example, when the vehicle is driven in a tilted manner, video data may be recorded based on the voice of the other party such as “O” in addition to the voice in the room. For example, when the drive recorder has a function of recording an event by operating a predetermined switch, for example, when a partner who has been driving is getting off and getting closer, operating the predetermined switch Although the event can be recorded, the pressing process is complicated, and there is a possibility that it cannot be operated tightly. Even if it is equipped with a function to automatically record an event by the output of the acceleration sensor when the other party hits or shakes the vehicle after being approached, There is a problem that event recording is not automatically performed when the value is small. As in this embodiment, it is preferable that event recording can be automatically performed based on a change in sound or the like because video data can be reliably recorded.

  When video data is recorded triggered by a change in the sound of the vehicle outside or inside the vehicle as described above, for example, the microphone is incorporated in the radar detector 1 to record the voice, and then the control unit when passing through the same place 18 may output the sound at a predetermined point in front of it. In this way, it is easy to remember the situation because the situation when it passed last time is known by voice. For example, a place where an animal appeared before may have the animal in the same place, so it is preferable to have a function of performing notification by voice reproduction or the like in front of the animal. With such a function, the driver may drive while paying attention to the surrounding area. In this case, it is preferable to reproduce the video data together because it is easier for the user who sees the video data to remember the situation, but it is preferable to output only the audio without reproducing the video. The audio data alone can sufficiently remember the situation at that time, and other useful information can be displayed on the display unit 4 by not reproducing the video data.

  It is preferable to have a function of recording an animal discovery point as an alarm target for a user like My Points and performing an approach alarm for the alarm target for the user. For the approach alarm, for example, a moving image / still image prepared in advance by CG or the like may be displayed in the alarm image display window W3.

[Alarm strength change function]
The control unit 18 may have a function of changing the strength of the alarm based on the user setting. For example, it can be changed. In the mode setting function in the above-described embodiment, "on / off" is selected for the alarm of each item. In this embodiment, for example, a plurality of alarm levels are prepared, and in the case of alarming, the alarm levels can be selected. For example, in the case of notification by voice, the level of the alarm is changed by, for example, changing the voice level (for example, increasing the volume of a stronger alarm), changing the content of the generated voice itself, and using the display unit. In this case, for example, the content to be displayed and the notification mode may be changed. Furthermore, it is more preferable, for example, to increase the location and frequency at which the alarm is issued as the level of the alarm is higher.

  Alarms are classified into two levels, for example, a normal alarm and a higher level alarm or a lower level alarm, or three levels as weak, normal and strong, or more. Although it is good, if the number of levels is increased too much, the setting is complicated and the effect caused by the level division does not increase so much. For example, if there are two levels, a normal level and a stronger level, even if the user is not aware of the normal level alarm, if the strong alarm is issued by setting the mode, the alarm will be noticed and safe It is good because driving can be encouraged. For example, if a user who is likely to forget the seat belt is warned frequently, for example, in front of the entrance of the expressway, etc., the seat belt may be worn.

[Modified standby screen]
FIG. 28A shows an example of the standby screen. The standby screen illustrated has a layout in which three minimeters 37 are disposed vertically on the left half side and the right half side of the main display area R1. Each mini meter 37 includes an item name display unit 37a at the upper left, a character information display unit 37b at the lower left, and a circular meter-like display unit 37c at the right. The control unit 18 displays items of information to be displayed on the minimeter on the item name display unit 37a. In the example shown in the figure, the time, speed (0-180 km / h), and the number of satellites received are displayed in order from the top on the left side, and the calendar, compass, and atmospheric pressure are displayed in order from the top on the right side. The control unit 18 displays information on each item using one or both of the character information display unit 37 b and the meter-like display unit 37 c. For example, the minimeter 37 at the upper left "time" digitally displays the current time on the character information display unit 37b, and displays the current time on the meter-like display unit 37c as a schematic diagram of an analog clock. As described above, as the type for displaying the same contents in the character information display unit 37b and the meter-like display unit 37c in different modes, there are “speed”, “compass”, “atmospheric pressure” and the like in addition to this “time”. The mini meter 37 for the upper right "calendar" displays the day of the week ("Tuesday" in the example shown in the figure) on the character information display section 37b, and "Month" in the upper stage and "day" in the lower stage in the meter style display section 37c. indicate. As described above, there is also a type in which the character information display unit 37 b and the meter-like display unit 37 c are combined to display one piece of information. Further, the mini-meter 37 for the “number of satellites received” at the lower left displays the number of satellites currently received on the meter-like display unit 37c without displaying the character information display unit 37b. As described above, there is also a type in which information is displayed using one of the character information display unit 37b and the meter-like display unit 37c. Information displayed on each minimeter 37 may be changed by setting.

  Information relating to the speed limit may be provided as an item to be displayed on the minimeter 37. As a display example of the information related to the speed limit, for example, as shown in FIG. 28 (b), for example, the control unit 18 displays “speed limit” on the item name display portion 37a, and for example, on the character information display portion 37b. It is preferable to display the speed limit in characters like "60 km / h" and display a mark imitating a traffic sign of the speed limit on the meter-like display unit 37c. In this way, for example, at a speed limit switching point, which has a function to notify the speed limit by voice or the like, even if you miss it, you can see the standby screen in this embodiment, and the road you are currently running It is good because you can check the speed limit. In addition, for example, as shown in FIGS. 18 and 19 and the like, the speed limit is displayed in a state where the alarm object is approached and the map screen is displayed, but in this embodiment, the map screen is displayed close to the alarm object. It is good to know the speed limit in the state of the standby screen before the transition to, and the current road limit is displayed by looking at the standby screen that displays the speed limit even in sections where traffic signs are not installed on the actual road Since the speed can be confirmed, the possibility of exceeding the speed limit can be suppressed as much as possible.

  As items displayed on the mini meter 37, it is preferable to provide information for specifying an alarm target. For example, when approaching the alarm target, the control unit 18 may display information on the alarm target on the minimeter 37 at a predetermined position without switching to the alarm screen using the map screen described above. If it does in this way, while alerting desired information using a stand-by screen, an approach warning of a warning object may be performed. As information for specifying the alarm target, for example, the control unit 18 displays a target icon to be drawn at a location corresponding to the installation position of the alarm target on the map on the map screen on the meter wind display unit 37c, and a character information display unit The remaining distance to the alarm target may be displayed on 37b. Furthermore, the control unit 18 may have a function of changing the color of the frame of the minimeter 37 and / or the background color according to the color of the alarm target (red, yellow, blue, green). By changing the color of the frame and the background color, it is possible to easily understand the approximate type of the alarm target, and it is more preferable to change the background color because the degree of understanding increases.

  The alarm target approach warning using the standby screen is not limited to the one using the detailed minimeter 37, for example, the small meters 32b and 32c shown in FIG. 3 or the like, or the large meter shown in FIG. It is preferable to use a predetermined element constituting the standby screen of the meter 38a or the like. For example, the standby screen shown in FIG. 29A has a layout in which a large meter 38a is arranged on the right side of the main display area R1, and two small meters 38b and 38c are arranged on the left and right sides. In the illustrated example, the control unit 18 displays a clock (analog) on the upper small meter 38b, displays a compass on the lower small meter 32c, and displays satellite information on the large meter 38a. In this example, the large meter 38a displays a picture schematically showing the position of the satellite receiving the radio wave on the sky.

  The alarm using the large meter 38a is, for example, when an alarm target exists within a predetermined distance from the own vehicle position, for example, the center of the circle of the large meter 38a is set to the own vehicle position, and the front in the traveling direction is set to the upper side of the circle, for example. The mark which specifies the warning object is displayed on the corresponding position of the warning object in the circle. This mark may be, for example, similar to the target icon. In this way, the notification of the alarm target using the large meter 38a loses the map information on the map screen, and draws the vehicle icon and the target icon etc. in a predetermined positional relationship. By doing this, it is possible to recognize the approximate position of the alarm target without displaying the map screen.

  As an example of an alarm using the large meter 38a, for example, as shown in FIG. 29 (b), (c) etc., an own vehicle icon 39a is displayed at the center of a circle, and an alarm object existing around it is displayed. It is preferable that the layout is such that the mark 39b specifying the is displayed at a position where the relative positional relationship is matched. In addition, as shown in the figure, a plurality of lines of concentric circles 39c of a true circle centering on the vehicle icon 39a and concentric circles 39 'of an ellipse are displayed, and the diameter of each circle is set to a predetermined distance (for example, 500 m). It is good because the approximate distance to the alarm target is also known. Drawing the true circle concentric circle 39c as shown in FIG. 29 (b) results in the 2D aspect of the plan view, and drawing the elliptical concentric circle 39c 'as shown in FIG. 29 (c) results in the 3D aspect of the bird's eye view .

  In the alarm including the relative positional relationship of the alarm target using the large meter 38a, since the display area is smaller than the alarm using the map screen using the entire main display area, the target displayed at the position of the alarm target The icons will also be smaller, and new challenges will arise. In order to solve this problem, for example, it is preferable to display the color of the outer frame of the large meter 38a and the background color in the circle of the large meter 38a with the color to be alerted (red, yellow, blue, green). In this way, it is sufficient to know the approximate type of alarm object from the color concerned.

  In the hybrid vehicle standby screen shown in FIG. 3D, the two mini-meters 34a and 34b are displayed in the upper area, and the hybrid information is displayed in the lower area. The information displayed on the minimeters 34a and 34b may be switched by setting, and more preferably provided with a function of switching information displayed on the hybrid information by setting.

  Information relating to the driving check may be provided as an item to be displayed on a predetermined meter on the standby screen using the above-described large meter, small meter, and minimeter. The information on the driving check may display, for example, the driving state of the vehicle, the state of dangerous driving such as a sharp steering wheel or a sudden braking, or eco-drive information on whether the eco-driving is performed to improve fuel efficiency. For example, a predetermined mini-meter 37 is used to display information on dangerous driving. For example, from the output of the acceleration sensor, the control unit 18 determines that the background color of the minimeter 37 is green when the acceleration is less than the first reference value, and is less than the second reference value greater than the first reference doctor. If the background color of 37 is yellow, and if the second reference value is exceeded, the background color of the minimeter 37 may be displayed in red, and a mark identifying a sharp brake or a sharp handle may be displayed in the meter. In addition, the control unit may have a function of displaying eco-drive information on a mini meter or a sub meter. For example, the eco-drive information is obtained by marking whether the eco-drive is being performed based on information such as rapid acceleration, rapid deceleration, idling time, availability of driving at economic speed, and the like. The control unit 18 may display the score thus obtained on a predetermined minimeter, or may obtain the score at predetermined time intervals, and display the change / history of the constant on the small meter. Further, the control unit 18 records, for example, the marking result of eco-drive information in a predetermined traveling unit such as every one traveling, and compares the marking result based on the present traveling with the marking result based on the past traveling such as the previous time. , It is preferable to have a function of informing the increase or decrease of points. In this way, it is good to know whether or not the current driving has achieved more eco-driving. The function of informing the increase in the number of points, for example, is easy to borrow a story because it has a high degree of recognition when matched to the color scheme of the signal. For example, the signal color scheme may be red when it gets worse, yellow when it doesn't change, and green when it gets better.

  The standby screen is provided with various meter-like display units such as a large meter, a small meter, and a mini meter, for example. For example, if the color is changed with the `` base color '' setting item belonging to the system, for example, the entire main display area may be changed, but if the inside of the circular area of the meter is changed and the outside is not changed Good (see FIG. 30). For example, the background color of the main display area may be unified to a chic color such as black, and the changed color may be conspicuous by changing the background color within the circular area of the meter.

[Linkage function with head-up display, etc.]
A head-up display may be connected to the radar detector 1 and provided with a function of displaying information such as the current traveling speed and speed and various alarms on the windshield of the vehicle using the head-up display. In this way, it may be smart, and the driver can recognize the traveling speed, the content of the alarm, etc. without greatly changing the line of sight while looking forward, for example.

  When the head-up display is linked and the drive recorder is mounted, it is preferable to set the head-up display to be displayed in the shooting area of the drive recorder. In this way, for example, the traveling speed and the content of the alarm may be reflected and recorded in the video data photographed by the drive recorder. For example, when the recorded video data is played back later, for example, the traveling speed is displayed together with the scenery while traveling, so it is easy for the user such as the driver to easily check which place is traveling at what speed. Also, the user can check, for example, the location where the warning is issued from the outside landscape when the alert is notified, and store the location where the alert is notified in combination with the printing of the outside landscape. This makes it easy to do so and can contribute to safe driving when traveling on the road thereafter. It is more preferable to have a function of adjusting the degree of reflection to the windshield of the head-up display. By adjusting the degree of reflection, the speed, warning, etc. can be more clearly reflected in the video data taken by the drive recorder.

  Usually, the shooting area of the drive recorder is adjusted so that the front view of the vehicle can be seen, and the display unit 4 of the radar detector 1 arranged on the dashboard of the vehicle or the like is out of the shooting area. Then, the display of the head-up display output from the radar detector has a positional relationship such that it is reflected by the drive recorder. By having such a feature, for example, the above-described effects can be achieved, and for example, even a drive recorder that does not have a GPS function can record the traveling speed.

[Data update function in Bluetooth (registered trademark)]
For example, when data is updated for data about an alarm target for alarming a GPS, the above embodiment has described an example using the memory card 11, but the present invention is not limited to this, and wireless communication function It is good to do using it. For example, the radar detector 1 of the embodiment described above has a wireless LAN connection function using a WiFi connection. For example, when the control unit 18 detects that the button area of “manual download” or “automatic download” is touched in the state where the WLAN setting screen (2/3) shown in the center of FIG. Then, a predetermined process for downloading the update data is executed to update the data. In this case, for example, it is necessary to connect the radar detector 1 and the smartphone in advance via a wireless LAN, and in order to perform the connection, for example, it is necessary to turn on the debugging of the smartphone and there is a problem of being bothersome. . In order to solve the problem, it is preferable to have a function of performing data communication by wireless communication between the radar detector 1 and a portable terminal such as a smart phone using Bluetooth. For example, when an application for data update is installed in a smartphone and the application is activated, the connection between the smartphone and the radar detector 1 is established by Bluetooth, and new update data is wirelessly transmitted from the smartphone to the radar detector 1 . The radar detector 1 updates data based on the acquired update data. It is preferable that an application for performing various settings of the radar detector 1 is installed in a mobile terminal such as a smartphone, and a function capable of setting the radar detector 1 by executing the application is provided. In this way, the user such as the driver can perform the setting of the radar detector 1 by operating the familiar smartphone or the like, so the setting can be easily performed. Since operation can also be performed at hand, it can be performed more easily. As the setting operation is simplified, the awareness of switching settings is strengthened, the radar detector 1 can be configured with a setting that suits the user, and the necessary information can be provided without excess or deficiency. It is good because it can be notified.

[Screen OFF function except when warning]
The control unit 18 preferably has a function of making the display unit 4 in a non-glare state at normal times when no warning is issued. For example, in the above-described embodiment and the like, in a normal time when no warning is issued, for example, a standby screen or the like is displayed to generate some information. In this configuration, the display unit 4 always emits light, and there is a problem that it is usually dazzling. When equipped with a function to make the display unit 4 not dazzling at normal times when no warning is given as in this embodiment, the dazzling is eliminated at normal times. For example, it is usually dazzling, so it is suitable for users who do not need screen display. Functions can be provided.

  The function of making the display unit 4 not dazzling is, for example, to draw the entire screen of the display unit 4 in, for example, black or other dark colors / non-dazzling colors. It is more preferable to turn off the power. In order to solve the same problem, the display unit 4 may be provided with a function to hide the screen.

[Ambient camera display function]
The radar detector 1 is provided with a front camera for capturing the front of a vehicle and a side view camera for capturing the left and right of the vehicle. As the front camera, for example, a wide-angle camera attached near the front bumper of the vehicle may be used, and as the side view camera, for example, a wide-angle camera attached near the side mirror of the vehicle may be used. When the control unit 18 of the radar detector 1 recognizes that it will merge at the intersection of the road and the like based on the map information stored in the radar detector 1, for example, the display unit 4 or the display means such as the head-up display described above. It is preferable to provide a function of displaying a video captured by the front camera and automatically displaying a video captured by the side view camera when, for example, a blinker signal is received from the OBD information. In this case, it is preferable that the driver does not have to switch the camera image displayed on the display unit manually.

  The switching of the camera to be displayed is not limited to the one based on the above-described map information, and may be performed based on an alarm target, for example. For example, the above-described front camera and a back camera capable of photographing the rear of the vehicle are provided, and both cameras are connected to the radar detector 1. For example, the control unit 18 may display an image captured by a front camera before passing an alarm target such as Orbis and display an image captured by a back camera after passing an alarm target such as Orbis. In this way, switching of a camera for displaying an image is more preferable to one based on the above-described map information because useful information can be obtained rather than one based on an alarm target.

  In the case where the front camera captures an image before passing based on the alarm target and the back camera captures an image after passing, in particular, the control unit 18 may record the captured video in, for example, the memory card 11 or the like. It is preferable to record because the situation around the vehicle before and after passing can be confirmed later.

[Alarm function based on captured image data]
The radar detector preferably includes an imaging unit for imaging the front, and has a function of emitting an alarm based on image data obtained by imaging the imaging unit. The imaging means may be integrated with the main body of the radar detector 1 or may be a separate imaging means. A separate body is preferable because it is easy to install the photographing means in a place where it is easy to capture the target video.

  The alarm based on the image data may be performed, for example, when a predetermined detection target exists in the captured image data. The detection target may be, for example, a signboard that promotes safe driving, a signboard that notifies the existence of an alarm target ahead of the road on which the vehicle is traveling, and the like. One of the signboards, “control warning signboard”, may be detected. The control unit 18 may be provided with a function of detecting and warning a “control warning signboard” by, for example, real-time image processing for image data obtained by photographing with the photographing means.

  The “control warning signboard” is also referred to as “pre-warning sign” or “notice sign” and, for example, as shown in FIG. 31, in front of the point where speed control is being performed , A warning warning sign 73 is installed. In the illustrated example, the control warning signboard 73 is a vertically long board, with white background for blue, and letters such as “speeding monitoring” are handwritten. In addition, although a concrete figure is omitted, a signboard warning of control such as "speed automatic regulator installation route" etc. is installed in a predetermined distance before the installation position of the route where the automatic speed regulation device is fixedly installed. Ru. The characters displayed on these control warning signs are not limited to the above. For example, there are several types such as "automatic speed control machine installation section", "speed automatic monitoring", "automatic speed control route", Limited to specific characters. Therefore, the control unit 18 performs, for example, predetermined image recognition processing on the image data obtained by photographing with the photographing means, extracts, for example, a signboard portion, performs character recognition processing described therein, and In the case of a registered character, an alarm based on image data is issued. Since the character recognition processing performed here may be performed on a specific character, real-time determination can be performed even if the CPU of the control unit 185 is not very high.

  Thus, for example, with the function of detecting and notifying a control warning signboard, position information is not registered and a warning based on GPS can not be performed, but it is also possible to give a warning to a speed control device such as Orbis It becomes. Orvis and other speed control devices that have not registered location information is a newly installed, and it is a good place to promote safe driving based on recent traffic conditions etc. It is good because it can contribute to safe driving by giving an alarm.

  In particular, a signboard installed in front of a small or mobile orbis has a problem that a driver or the like is easily overlooked because only a simple standing signboard is erected. With the function of this embodiment, even a simple standing signboard that is easily overlooked is detected and notified, so that the driver can surely recognize its presence.

[Alarm function using road elevation data]
Radar detectors should record road elevation data. It is preferable that the control unit 18 has a function of acquiring from the GPS information the position information of the longitude and the latitude of the current point as well as information of the altitude and also using the acquired information of the altitude to specify the road currently traveling. This enables stable road identification. The control unit 18 may issue a warning regarding the identified road currently being traveled, and may not issue a normal warning for a warning target that is not related to the current road. The absence of a normal warning may include, for example, no warning and a light / weak warning. In this way, warnings relating to the road on which the vehicle is running are concentrated, and it is possible to prevent unnecessary warnings from being generated or to make notifications weak and unnoticeable. For example, when an expressway and a general road exist side by side, it may not be possible to specify whether the vehicle is traveling on an expressway or a general road only with the position information of longitude and latitude. If it is prepared, stable road identification becomes possible. For example, when it is recognized that the vehicle is traveling on an expressway, speed warning devices such as Orvis provided on general roads and other warning targets should not be given regular warnings. Then, it is good because it does not emit an unnecessary alarm. In addition, conversely, when it is recognized that a general road is being traveled, it is preferable not to perform a regular warning on a warning object regarding a freeway.

[AR alarm]
The drive recorder and the radar detector are linked to each other, and the radar detector preferably has a function of analyzing the GPS information and a live image taken by the drive recorder and alarming with AR. When the alarm of the AR is performed, a desired alarm and notification are given to the image being actually photographed, so that the reality is increased and the attention may be more effectively reminded. The AR alarm may be notified, for example, by superimposing it on the image by the AR in a mode in which the presence of the alarm target stands out in a video shot and displayed on a display unit or the like. In the aspect that stands out, for example, an instruction element such as a frame or an arrow may be created by CG or the like and displayed in association with the alarm object in the image. The associated display may be arranged, for example, so that the user can easily understand that the indication element points to the alarm object, for example, it may be superimposed on the alarm object or arranged near the alarm object. When the indicating element is a frame, it may be arranged to surround all or part of the alarm object, and when the indicating element is an arrow, it may be arranged such that the alarm object is present at the tip of the arrow.

  As an example, for example, when a photographed image is analyzed and a policeman is recognized at an intersection, an AR alarm may be issued so that the presence of the policeman is known. When a camera for photographing the rear of the vehicle is provided, it is preferable to recognize a white bike, a police car, a masked police car, and the like based on image data obtained by shooting the rear of the vehicle and issue an alarm by AR. In addition, it is preferable to create a character representing the alarm target object by CG or the like, and display the character superimposed on the display position of the alarm target object to perform the AR alarm.

  The function of the drive recorder may be mounted on the radar detector described in the above-described embodiment, modification, or the like. The radar detector 1 is preferably installed on the dashboard in order to improve the visibility of the display unit 4 from the driver. In a conventional drive recorder with a main body attached to a predetermined position of a vehicle, a camera for shooting the front of the vehicle has its shooting direction facing forward in the horizontal direction, and the angle of view of the camera is based on horizontal Adjust to equal angles on the upper side. In order to facilitate such adjustment, for example, when the case is rectangular, the orientation of the camera is parallel to the bottom surface of the case. In this way, when the stand is mounted upright so that the bottom surface of the case is parallel to the floor surface of the vehicle, the camera also faces forward in the horizontal direction.

  In the case where the radar detector 1 is installed on the dashboard of the vehicle 80 in the same manner as the conventional general one described above in the radar detector 1 having the drive recorder function, as shown in FIG. As shown, the field angle 81 of the camera mounted on the radar detector 1 is the bonnet 82 of the vehicle 80, and the hood 82 is reflected in the camera, and the lower half of the field angle 81 of the camera There is a problem that most are blind spots.

  Therefore, in the present embodiment, for example, as shown in FIG. 32 (b), when the camera 8 is mounted on the rear surface 2a of the case 2 facing the front of the vehicle in the attached state of the case 2 standing in a rectangular shape, It is performed in a state where the corner range is obliquely upward at a certain angle. In this case, for example, when the case 2 is mounted on the dashboard of the vehicle 80 so as to stand upright, the camera 8 is directed obliquely upward, and, for example, the angle of view as shown in FIG. 81 is also in the range of the front upper side of the vehicle 80. Then, it is preferable to set the lower boundary of the angle of view 81 above the bonnet 82 with the radar detector 1 installed, since the camera 8 will have no blind spots.

  FIG. 32D shows a modification of the radar detector 1 having a drive recorder function. In this modified example, the outer shape of the case 2 'has a substantially single trapezoidal longitudinal cross section, and the rear surface 2'a has an inclined surface. The center of the angle of view 81 of the camera is perpendicular to the inclined surface. Thereby, since the direction of the camera 8 and the rear surface 2'a are aligned, the camera 8 can be mounted on the case 2 without conspicuous.

  For example, when the drive recorder integrated type radar detector is mounted on the dashboard of the vehicle, and the camera is installed to face horizontally forward, as described above, for example, as described with reference to FIG. In addition, there is a problem that the bonnet of the own vehicle is reflected in the video data taken by the camera. If the angle of view of the camera 8 is directed obliquely upward as in the above embodiment, the dead angle is eliminated or reduced, so that the problem can be solved. On the other hand, the resolution of the video data photographed by the camera 8 decreases from the center to the periphery. Therefore, as in the above embodiment, when the camera 8 is directed obliquely upward, a new problem arises that the vehicle ahead etc. is located near the periphery of the range of the angle of view of the low resolution camera 8 and an accident in the drive recorder Considering video recording such as time, for example, the upper part of the windshield is advantageous for mounting the drive recorder.

  A wireless communication function such as WiFi is mounted on a radar detector integrated with a drive recorder, and the radar detector 1 is attached to a predetermined position on the windshield of a vehicle, for example. A terminal such as a smartphone equipped with a wireless communication function such as WiFi and a display unit is prepared and maintained in a wirelessly connected state with a radar detector, and the radar detector transmits a warning screen and a photographed image to the terminal. The terminal has a function of displaying the received warning screen or captured video on the display unit of the terminal. In this way, for example, a forward scenery such as a forward vehicle can be photographed in an area near the center of the high resolution gamera. By installing a terminal such as a smartphone on the dashboard or placing the terminal at the hand of the user such as a driver, the user may check the warning screen and the photographed image on the terminal near the user. In addition, by implementing such a function, for example, even if the drive recorder integrated type radar detector is a model without a screen or a model with a small screen of about 1.5 inches, for example, a warning screen or an image taken Visual data can be seen on a large screen in a clean state.

[Radar detector with dual screen drive recorder function]
A radar detector having a drive recorder function has, for example, a drive recorder function. For example, as shown in FIG. 33, the radar detector 1 of this embodiment includes a horizontally long case 2 and is installed on a dashboard of a vehicle via a bracket 3. It is preferable that the radar detector 1 can be installed on the back of the sun visor, the back of the rearview mirror, or the like according to the change of the bracket 3. The display unit 4 provided on the front surface of the case 2 of the radar detector 1 includes a first display unit 4 a and a second display unit 4 b arranged in parallel in the horizontal direction.

  The radar detector 1 with drive recorder function uses a video sensor SoC with CMOS Sensor I / F that can perform image processing for both the function as a radar detector and the function as a drive recorder, processing as a radar detector in one chip and , It is good to perform processing as a drive recorder.

  The radar detector 1 is preferably provided with two screens, a first display unit 4a and a second display unit 4b, and a setting function for setting the type and content displayed on the two screens. For example, the first display 4a on the left may be set as the display for the drive radar, and the second display 4b on the right may be set as the display for the radar detector. In the case where it is possible to perform the setting for replacing or outputting another image / video, it is more preferable to use the first display 4a described above as a drive recorder and the second display 4b as a radar detector. When provided with the function of the drive recorder, the camera is usually provided near the center in the width direction of the vehicle, so the radar detector 1 having the drive recorder function of this embodiment is installed, for example, near the center in the width direction of the vehicle Good. In this case, for example, in the case of a right-hand drive vehicle such as a Japanese car, the second display 4b is disposed closer to the driver while driving, which is useful for the driver in detecting the radar in driving the vehicle. Make it easy to check the notification of the video by the machine. Further, since the first display unit 4a is disposed closer to the front passenger seat, for example, when the passenger is present in the front passenger seat, it is easy for the passenger to view the video taken by the camera of the drive recorder function.

  Although not shown, the radar detector 1 including the first display unit 4a and the second display unit 4b has an image input terminal connected to another external camera, and the image from the other external camera is It is preferable to display on one of the display unit 4a and the second display unit 4b, and the other display unit has a function of displaying a display screen for a drive recorder or a radar detector. For example, when displaying a display screen for a radar detector on the other display unit, it is possible for a driver to receive notification of an image by a useful radar detector in traveling of a vehicle and to view an image captured by an external camera. It is good because it can. In particular, the external camera may shoot an area other than the front of the vehicle. When an area other than the front of the vehicle is to be photographed, a scene outside the field of view of the driver facing forward during traveling forward can be displayed on the display unit. Further, it is preferable that the external camera is set so as to shoot in a different direction from the camera for the drive regenerator. In such a case where it is set to shoot different directions, it is preferable to display an image taken by an external camera on one display unit and display an image taken by a drive recorder camera on the other display unit. In this way, images taken in different directions can be displayed simultaneously on two screens.

  In the system configuration in which the external camera described above is connected, the control unit 18 of the radar detector 1 has a setting function of setting the type and content to be displayed on the two screens of the first display unit 4a and the second display unit 4b. good.

  When the display at normal time without alarm is configured to output and display the video data captured by the camera for drive recorder or the external camera in both the first display unit 4a and the second display unit 4b, the approach of the alarm target When an alarm or other alarm detector event as a radar detector occurs, at least one of the first display unit 4a and the second display unit 4b may display an alarm / notification screen based on the function of the radar detector. It is preferable to have a function of setting a display unit that displays an alarm / notification screen based on the function of the radar detector. Such settings include, for example, “display alarm / notification screen on both first display 4a and second display 4b”, “display alarm / notification screen on first display 4a”, “on second display 4b” It is preferable to have a function to select from the display of the alarm / notification screen. For example, the setting may be simple even if two of the three types illustrated can be selected, but it is more preferable that all three types can be selected. Further, when the function to be set is not provided, for example, a screen based on the function of the radar detector may be displayed on only the second display unit 4b. If this is done, the alarm screen is displayed on the second display unit 4b on the driver's side of the vehicle with the right handle while displaying a predetermined camera image, which may facilitate the driver's recognition of the alarm screen.

[Radar detector with multiple screens (total number of cameras is larger than the number of display units)]
The radar detector is provided with a plurality of display units regardless of the presence or absence of the drive recorder function. For example, the total number of built-in cameras mounted in case 2 and external cameras connected to case 2 is the number of display units In the mode, it is preferable to set the number to 2 or more (3 or more in the present mode), and based on the condition set when the number is large, video data photographed by a predetermined camera equal to or less than the number of display units It is good to have a function to display in By switching the camera to be displayed under a predetermined condition and displaying it on a predetermined display unit, for example, an appropriate video can be displayed.

  For example, when there are two display units as in the present embodiment and there are four cameras that shoot front and rear and left and right, images from the two predetermined cameras are selected and displayed on the predetermined display unit It is good to have the function to The shooting area of the camera that shoots each of the left and right directions is preferably not diagonally right, for example, diagonally left front or diagonally right front. These imaging areas may include an area that is blind or difficult to see from the driver. The two predetermined cameras that output the video to be displayed on the display unit may be, for example, cameras that capture the front of the vehicle and the direction in which the vehicle is going to travel. For example, the direction in which a predetermined direction of traveling is photographed may be determined based on a winker signal output as OBD information / vehicle information. For example, when the turn signal is a left turn, the control unit displays video data from the camera capturing the left side on a predetermined display unit. For example, when the turn signal is a right turn, the control unit displays an image from the camera capturing the right side The data is displayed on a predetermined display unit. Based on the signal of the shift lever position output in the OBD information / vehicle information, when the signal is in the R range, the control unit displays video data from the camera that captures the rear on a predetermined display unit.

  For example, when it is configured to display an image of a camera for capturing the front and an image of a camera for capturing the rear on the display unit when going straight ahead, a camera for displaying both when going straight and when going backward Therefore, the same switching display operation can be performed without performing control based on the signal of the shift lever position.

  The predetermined display unit for displaying the video of the camera based on the traveling direction may have a switching function according to the setting, but for example, the video data from the camera that shoots the front when it can not be switched It is good to display on the 1st display part 4a, and to display the video data from the camera which can image | photograph right and left or back on the 2nd display part 4b near a driver's seat. In this case, since an image obtained by imaging an area in the direction in which the vehicle is going to travel is displayed at a position close to the driver, it is easy for the driver to view and easy for the driver to check. Since the video data obtained by photographing the front is also an area that can be viewed directly by the driver directly via the windshield, it is good because the influence of the difficulty in seeing it even if displayed at a position away from the driver is small.

  Further, as another display mode, for example, video data from a camera that meets a predetermined condition is displayed on one display unit, and a plurality of cameras are divided into a plurality of screens on the other display unit. It is good to reduce the display of the video data from. Video data from a camera meeting a predetermined condition may be switched, for example, in a predetermined order or at random, but if it is video data from a camera that captures the traveling direction of the vehicle described above, it is a video useful for driving More preferable. One display unit for displaying an image from a camera meeting the predetermined condition may be, for example, the first display unit 4a on the side away from the driver's seat in the vehicle with the right steering wheel, and image data from a plurality of cameras The other display unit that is reduced and displayed at the same time may be, for example, the second display unit 4b close to the driver's seat side in a right-hand drive vehicle (see FIG. 34A). By reducing the display, each of the divided displays is reduced, but by reducing the display closer to the driver's seat, the driver is prevented from being difficult to see. In FIG. 34, video data to be displayed on each display unit is indicated by alphabets (a, b, c, d) for convenience.

  As shown in FIG. 34A, for example, when the second display unit 4b is divided into four, video data from four cameras can be simultaneously displayed. Further, as shown in FIG. 34 (b), in each of the four divided images in the second display unit 4b, an image corresponding to the image data displayed on the first display unit 4a is, for example, a first indication frame of a predetermined color. It is good to surround by 90. By doing this, it is possible to easily understand which image is being displayed on the first display unit 4 a which is divided into four and displayed.

  Further, as shown in FIG. 34C, it is preferable to display a second instruction frame 91 so as to surround the outer periphery of the first display unit 4a in response to the display of the first instruction frame 90. In this way, the correlation between the video data being displayed on the first display unit 4a and the one video data divided and displayed on the second display unit 4b may be easily understood. If the display colors of the first instruction frame 90 and the second instruction frame 91 are the same color, it is preferable because the correlation becomes stronger, and more preferably the same color.

  When the display colors of the first indication frame 90 and the second indication frame 91 are the same system color or the same color, different colors are assigned according to the four display positions of the second display unit 4b to be divided and displayed or the four cameras. And more preferred. In this way, when the camera displayed on the first display unit 4a is switched, the display colors of the first instruction frame 90 and the second instruction frame 91 change, so that it can be intuitively understood that the camera has been switched, and the display color It is good because you can understand which camera image from.

  In the above-described embodiment, the video input terminal is provided and the external camera is connected by wire. However, the external camera may be wirelessly connected by wireless communication. The case 2 may be configured not to incorporate a camera but to capture an image from an external camera. In this case, for example, the camera may be installed at a predetermined position such as the information center of the windshield, and the main body provided with the display unit may be disposed at a position easy to be viewed by the driver on the dashboard. Because it is unnecessary to route the wiring, it is good.

[Upside down correspondence of radar detector 1 of two screens]
For example, as shown in FIG. 35 (a), the above-described two-screen radar detector 1 has a predetermined bracket 3 attached to the bottom of the case 2 of the main body, for example. Fasten on the dashboard of the vehicle with components. In FIG. 35, video data to be displayed on each display unit is indicated by alphabets (A, B) for convenience. The radar detector 1 may be configured to be attached and fixed to the back side of the sun visor, the back side of the rearview mirror, the windshield, etc. using another bracket 3.

  In this case, as shown in FIG. 35 (b), the radar detector 1 is attached to the vehicle with the top and bottom of the case 2 turned upside down, so that the first display 4a and the second display The position viewed from the driver side of 4b is also oppositely arranged on the left and right. Therefore, the control unit 18 of the radar detector 1 changes the image displayed on the first display unit 4a and the second display unit 4b in accordance with the vertical direction of the radar detector 1, and turns the image upside down. Control to display the In this way, regardless of the mounting attitude of the radar detector 1, the same display content can be notified on the side closer to the driver side, and for example, information that the driver wants to show can be arranged on the driver side . Similarly, even on the side far from the driver side, the same display content can be notified regardless of the mounting attitude of the radar detector 1. The vertical direction may be detected by, for example, a G sensor.

  The display control function of this radar detector may be implemented with or without the drive recorder function, but in the case of a radar detector equipped with the drive recorder function in particular, the driver side, for example, regardless of the installation position of the radar detector. It is good to use the side near to for alarm information.

[Camera position of the two-screen radar detector 1]
For example, as shown in FIG. 33C, the mounting position of the camera 8 may be shifted from the center in the left-right direction, and may be disposed just behind or behind the first display 4a. If an image taken by a camera is displayed on the first display unit 4a, it is preferable because the feeling of viewing through the first display unit 4a can be produced. In the case of having a function of switching and setting a display unit for displaying a display of an image captured by a camera, it is preferable to display the first display unit 4a as a default.

[ASIC-equipped radar detector]
The circuits of the various radar detectors described above may be the same as those employed in the prior art, but it is more preferable to make them one chip. As components built in the chip, for example, LNA, MIXER, VCO, IF AMP, IF detection, signal processing, FSK (K-band orbit identification) and the like may be provided. In this way, effects such as downsizing, cost reduction, reduction in the number of parts, performance stabilization, and prevention of circuit copying are exhibited.

VCO built-in VCO temperature compensation
The various radar detectors etc. mentioned above have a type which mounted ASIC. The varicap capacitance inside the VCO incorporated in such an ASIC fluctuates due to temperature change, and the oscillation frequency of VOC fluctuates accordingly. In order to solve the problem, it is preferable to provide a function of compensating for a frequency shift due to a temperature change with an external element.

  For the compensation function, for example, an input terminal (Vcont) for setting a VCO provided in the ASIC may be used. The VCO outputs a signal having an oscillation frequency corresponding to the voltage value input to Vcont. Therefore, for example, a temperature sensor is mounted on a radar detector or the like, and the function of detecting the ambient temperature and the function of adjusting the voltage value input to Vcont based on the detected ambient temperature are used. A thermistor and LTC compensation method may be implemented. With this configuration, correction can be performed within a certain voltage range (for example, 0.5 to 2.5 V), and fluctuations can be suppressed. Since partial voltage is used, it is difficult to achieve an effect at a low voltage, but it can be handled at a predetermined voltage or higher.

  Further, an input terminal (Vadj) for adjusting the VCO may be used. When a predetermined voltage is input to the Vadj terminal, the VCO changes and adjusts the oscillation frequency according to the input voltage value. Therefore, for example, a temperature sensor is mounted on a radar detector or the like, and the function of detecting the ambient temperature and the function of adjusting the voltage value input to Vadj based on the detected ambient temperature are provided. A thermistor and LTC compensation method may be implemented. With such a configuration, correction can be performed within the entire voltage range (for example, 0 to 3 V), and fluctuations can be suppressed. By using LTC, linear compensation is possible, and it does not vary from room temperature.

[Use information about disasters distributed from GPS (Michibiki)]
One of the services provided by Michibiki (Quasi-Zenith Satellite System) QZSS is the disaster and crisis management reporting service. This disaster / crisis management notification service is a service that is sent from MICHIBI from government agencies for disaster prevention and crisis management about disaster information such as earthquakes and tsunamis, crisis management information such as terrorism, and evacuation advisory status. This service delivers messages such as disaster information to users, and the signal used to transmit disaster / crisis management reports (hereinafter referred to as “disaster reports”) is a GPS commonly used for satellite positioning. The same waveform with the same frequency as the signal transmitted from the hygiene. Therefore, for example, GPS devices equipped with GPS units such as the various radar detectors described above, navigation systems, drive recorders, etc. can receive disaster reports by the GPS units.

  For example, during a disaster, it is assumed that the power network is destroyed and the mobile network cannot be used. On the other hand, as long as there is fuel, the vehicle functions as a power supply for GPS devices and the like. GPS devices can also be battery powered. A radar detector or other GPS device may be provided with a function for receiving a disaster report and a notification function for performing notification based on the received disaster report.

  For example, in Kagoshima Prefecture, ash fall from Mt. Kirishima and Sakurajima is a problem, and ash fall is closely related to daily life so that forecasting of ash fall is announced in a weather forecast, and confirming ash fall forecast is a part of life It becomes. It is preferable that the information on the falling ash be informed. For example, the cause point and the predicted amount of ash fall may be reported, such as “currently a large amount of ash fall is expected from Mt. Kirishima”.

  The notification timing may be configured to notify when the engine is off when parking. It is recommended to operate with battery backup when the power is turned off, such as when the engine is turned off, and notify disaster prevention weather information (falling ash).

  For example, when the engine is off, disaster prevention weather information (falling ash) is often reported when reporting information such as the disaster source and the situation, degree, etc., such as "currently, a large amount of falling ash is expected from Mt. In particular, a warning message about the next action to be taken, such as “Let's take in laundry”, should be notified. When the engine is turned off, the vehicle often gets off, the vehicle is parked, and the driver often enters a house such as a home. Therefore, by notifying at that timing, a user such as a driver may easily move to the next action.

It may be notified when the engine is started, but desirably it is better when the engine is turned off. For example, when the engine is started, the vehicle is started as it is to go out somewhere. For example, assuming that leaving the house away from home for a certain period of time, reporting disaster prevention weather information (falling ash) at that timing For example, it is preferable in that it may give an opportunity to start again after taking measures against falling ash such as taking in laundry, but it is likely that it will have no time to leave, so the time after returning home etc. It is more preferable to notify when the engine with sufficient margin is turned off. In addition, it is possible to take measures such as putting the vehicle in a place with a roof such as a carport when the engine is off, or putting a cover on the vehicle at the time of getting off. You can take measures such as taking in laundry immediately.
Disaster prevention weather information (falling ash) also includes information on the predicted amount of falling ash. The predicted amount of ash fall is divided into four stages from 1 to 4. For example, 1 is “small amount of ash fall”, 2 is “slight amount of ash fall”, 3 is “large amount of ash fall”, and 4 is “fall of small cinders”. A GPS device such as a radar detector may have a function of changing an alarm depending on the degree. For example, it is better not to notify when 1 and notify when 2 or 3. In the case of 4, since it is necessary to escape, the disaster prevention weather information (falling ash) is not notified, it is preferable to issue an alarm prompting evacuation and not to notify the disaster prevention weather information (falling ash). In addition, it is preferable to notify only when the area and time zone correspond to the current position and the current time.

(Cooperation with wireless alarm)
The control unit of the radar detector or the like preferably has a function of linking the notification of the wireless alarm and the information of MICHIBI and reporting. The information of MICHIBIKI may be, for example, an eruption warning announcement / ash fall information. For example, alerting based on both alarms can be made larger by reporting the contents of a predetermined disaster notification such as eruption information emitted from guidance and radio information in association with each other.

When a predetermined radio is received as a timing of alarm, when predetermined information of MICHIBI (for example, issuance of eruption warning issuance / falling ash information, etc.) is received, a function of notifying also the predetermined information of MICHIBI is also provided. It is good to have. For example, at the timing of radio alarm, information on MICHIBIKI is read out by TTS or the like. For example, “You have received a digital radio. Also, there is an eruption warning issued on Mt. Kirishima (Moedake).
There is a possibility that administrative activities are activated when the predetermined radio signal is received, and if an eruption warning is issued at that time, there is a high possibility of administrative activities and countermeasures against eruptions, for example, the occurrence of traffic congestion was predicted. It is good because measures can be taken such as traveling on routes or routes that do not interfere with administrative activities.

You may make it alert | report when the predetermined information of MICHIBIKI is received, but since it is sent regularly, the same alarm will be repeated. Therefore, when notification is given each time the guidance predetermined information is received, notification may be frequently performed, which may cause confusion and may reduce the effect of the alarm. Therefore, once an alarm is issued, an alarm based on the same information may be performed when a predetermined alarm condition is satisfied. The predetermined alarm condition may be, for example, the elapse of a predetermined period. In this way, it is not noisy because at least the predetermined period is not alarmed. The predetermined period includes time and number of times. Further, it is preferable that the predetermined alarm condition is that another alarm has been performed, and in particular, it is preferable that the alarm condition is associated with the wireless alarm accompanying the reception of the wireless, because the relevance and the relationship are high.
In particular, it is good to use administrative radio such as police, firefighting and helicopters.

(Notification function based on tsunami and river flooding)
One of the predetermined information of Michibiki is “Tsunami Warning”, and there are a lot of types of contents of “Tsunami Warning”. For example, “141 Tsunami of the Great East Japan Earthquake will come”.

  A radar detector or the like stores and holds information with coastline information on a map. The control unit of the radar detector etc. has a function to output an alarm sound indicating that the current location is dangerous at the time of issuance of the content of the tsunami warning when the tsunami warning is near the current location. It is good. A message telling you that the tsunami will reach here (current location) is good. For example, it is good to notify the action to be taken now such as "Please head towards the mountain" or "Please evacuate to a high position".

  On the other hand, it is more preferable to have a function to suppress a warning that "the current location is dangerous" if the current location is sufficiently far from the sea. Although the warning may not be suppressed, it is preferable to perform notification using a screen without giving a voice warning.

  For example, a warning may be issued uniformly in a certain unit of the area where a disaster report is issued, such as a municipality, but a tsunami arrives at a high altitude such as the top of a mountain in the same area or away from the coastline. In some places where the possibility is low, even in a place where such a possibility is low, there is a risk of causing the driver to panic, confuse or cause unnecessary evacuation behavior. Therefore, as described above, it is preferable to alert the area specifically to danger as in a position where the distance between the present location and the coastline is short.

  Notification of tsunami warning may be provided with a function to notify based on the elevation instead of the function performed based on the distance from the coastline described above, and more preferably, a notification function based on the distance from the shoreline, and elevation It is good to have both of the notification functions based on, and it is more preferable to have a function to notify based on both information.

  For notification based on elevation, for example, contour line data is stored in a map, and when the current position corresponds to a height less than the height corresponding to the largest tsunami, an alarm sound indicating that the current position is dangerous is issued. Good. In areas where the sea level is low, seawater and the like may enter even if they are far from the coastline. For example, the height below the maximum tsunami should be less than 20 meters above sea level.

  The function of informing based on both pieces of information notifies, for example, when it corresponds to at least one, and it can be understood that, for example, when both informing conditions are satisfied such as near the coastline and low elevation, urgency is high. It is good to notify in a stronger notification mode. In addition, for example, even within the range of a certain distance from the coastline, when the elevation is higher than the height corresponding to the largest tsunami, it is preferable not to warn the tsunami, more preferably, the condition It is good to notify so that The notification may be, for example, to notify that “the tsunami is likely to occur / is generated, and the current location is close to the coastline but the altitude is high” so that the state is known. For example, even when moving in a direction away from the coastline in response to a warning of a tsunami, if the elevation in the area in the moving direction is low, the tsunami may reach a safe distance from the coastline. It may be safer to stay at the current altitude when the tsunami warning is reported. Therefore, for example, if the distance from the coastline of the current location and the altitude are reported by specific numerical values, providing useful information for allowing the user to judge which of the leaving from the coastline and the waiting there is safer. Can.

  Although the example mentioned above demonstrated alerting | reporting based on a tsunami, it is good also about the ridge of a river similarly based on the position of a river, and the elevation of a river.

(Combined use of location information and notification level)
The control unit such as the radar detector determines if there is a direction such as an earthquake, tsunami, eruption, or drought (dangerous place: disaster area) in the vicinity of the current location or in the direction toward the current location. It is good to provide the function which suppresses alerting | reporting when there is no alert | report.

  This form is to notify when a place that will exist in the near future is dangerous instead of the current position. For example, when a destination is set such as car navigation, it can be reported based on the planned travel route, but when a destination is not set, it is approximate based on the travel history from the departure place etc. It is good to predict the direction of heading and notify when there is a dangerous place ahead of that direction.

  In the disaster and crisis management reporting service of Michibiki, emergency earthquake bulletins, tsunami forecasts, eruption prediction information, weather alerts, flooding information are distributed, and the three highest priority, priority, and normal are prescribed as notification levels. Therefore, it is preferable to change the notification target area according to the highest priority / priority / normal priority. For example, it is more preferable that the highest priority is notified even if it is not near the current location.

(Evacuation function)
The radar detector is linked to the destination setting function of the vehicle, and the radar detector has a function of inputting an area having no disaster information to the destination setting function as a destination. In the case of a vehicle with an automatic driving function, if there is a current location in a disaster area, the car is moved to an area without disaster information by automatic driving. If people are on it, ask if you want to move. If there are no people at the time of parking etc., it is better to move the vehicle to the nearest safe area.

(Cooperation with drive recorder)
It is preferable that the log of the drive recorder has a function of recording that notification based on the disaster report has been made. By recording an event based on notification of a disaster, it is possible to record the status of a disaster or the like on which the disaster notification is based.

  For example, in cooperation with the radar detector and the drive recorder, the radar detector that has made a notification based on the disaster notification notifies the drive recorder that the notification has been made and the contents thereof. Based on the notification, the drive recorder performs event recording for recording a predetermined period before and after the notification, and records the notification contents in association with each other. In this way, when the user or the like sees the log later, for example, it is possible to know the location at the time of notification, remember that it was dangerous, etc., and confirm that it was successfully avoided.

  In particular, it is preferable to have a function to record an event based on notification of a disaster to a drive recorder equipped with a camera for photographing the inside of a vehicle. In the drive recorder, when shooting inside the car, you can record the state of the driver and passengers, for example, you can later check how you were frustrated when you were notified based on a disaster report, It is good because it can be used to study what kind of behavior a person takes.

  The communication that transmits the occurrence of a disaster is not limited to the disaster communication that is transmitted from the satellite described above, and, for example, V-ALERT (registered trademark) of the municipal disaster prevention information media using the new broadcast service i-dio. Various other things may be used, but it is particularly good to use disaster communication. Disaster communication covers the whole country, and can know detailed information such as the type and degree of disasters to notify and receive it using the GPS unit originally installed in the radar detector, so it is extra special It is good because it does not implement a good receiver.

[Recognition of passengers]
The various radar detectors and the like described above may be provided with a function of recognizing a passenger who has entered a vehicle, and may be provided with a function of issuing a different alert depending on the recognized passenger. In this way, it is preferable to be able to alert the passenger who has entered. The recognition function of the passenger may be performed by, for example, face or person authentication based on the captured image data by mounting a camera. The different warning may be, for example, determining a passenger and changing the content of the warning. For example, a radar detector having a function of displaying a character and reporting the change in the movement or the posture of the character or the voice of the character performs notification using a character according to the passenger. It is preferable to switch the presence / absence of notification of the character.

  Different alarms may have a function of switching to gender-specific, youth-oriented, or elderly content, for example. For example, for the elderly, it is preferable to give an alarm that strengthens the stop, pause, and reverse run from the enforcement once for the elderly, and for example, for the youth, it is preferable to perform an alarm that strengthens speeding and the like. It is advisable to register personal preference settings and issue an alarm with the non-powder setting registered for the passenger. In addition, when a person who is not registered drives, a burglar alarm may be given. This makes it possible to take measures against theft.

[Built-in i-dio tuner]
The various radar detectors and the like described above preferably include an i-dio tuner, and have a function of connecting to a car audio by wired communication or wireless communication. For wireless communication, for example, Bluetooth (registered trademark) may be used. The control unit has a function of outputting the sound received by the i-dio tuner from the car audio and displaying information transmitted by data broadcasting on the display unit. It may be displayed as one of the standby screens on the display unit of the radar detector. It is good to display the screen of the free digital broadcast service Amanek channel for car enthusiasts and out enthusiasts.

  A radar detector outputs an alarm sound from an internal speaker. During normal times, the sound received by the tuner should be output from the car audio, and during alarms, the alarm sound should also be output from the built-in speaker and car audio. It is better to switch the music received by the i-dio tuner to the output from the built-in speaker when the alarm is received, and issue the alarm from the car audio. Since the driver is listening to the sound from the car audio, the alarm effect is enhanced when an alarm sound / sound is output from the car audio. The music that has been output from the car audio up to now is switched and output from the built-in speaker, so the continuity of the music can be maintained.

[Door mirror built-in type]
The various radar detectors described above may be incorporated in the door mirror. When it is built in the door mirror, it may be displayed with a display on the mirror surface, or it is displayed via the half mirror when the mirror is a half mirror and the display unit is placed on the back side of the mirror and the display unit is lit. The display contents of a section can be visually recognized, and the entire surface may function as a mirror in the non-store state.

[Flip down monitor]
The various radar detectors and the like described above are equipped with flip-down monitors that automatically open and close with respect to the main body, and the main body is attached to a predetermined position of the vehicle. The body is mounted, for example, on a sun visor or mounted on a windshield using, for example, a predetermined mounting bracket. When the main unit is attached to the specified position of the vehicle, when the monitor is closed, the monitor becomes almost parallel to the ceiling or floor of the vehicle, and the area within the driver's field of vision decreases, and it feels in the way Suppress. At the time of alarming, a motor for opening and closing the monitor is driven to open the monitor, and an alarm screen is displayed on the display unit of the monitor. When the alarm is finished, the motor may be driven to return the monitor to the closed state.

[Attachment type to room mirror with existing monitor]
The various radar detectors and the like described above are rearview mirror-mounted radar detectors, and when attached to a rearview mirror equipped with an existing monitor, it is preferable that the existing monitor is not blocked. In this way, a radar detector can be attached to a room mirror with an existing monitor without compromising the visibility of the existing monitor, and it can be used even by users who do not like the type installed on the dashboard. It is good because it becomes possible.

  The structure that does not block the existing monitor is, for example, a space facing the existing monitor may be an open space, and in particular, part or all of the display of the radar detector is made of transparent EL and transparent on the front side of the existing monitor It is good to arrange an EL display. In this way, for example, even an existing monitor that occupies a large area with respect to the room mirror can ensure visibility. In a configuration using a transparent EL, it is better to have a function to control the display so that the transparent EL is not lit and is not displayed while the existing monitor is lit.

[Radar detector with USB output terminal]
The various radar detectors described above may be provided with a micro-USB power output terminal. In this case, for example, a smartphone or other portable terminal device may be connected to charge the battery.

[Simultaneous recognition suppression function of accelerometer of drive recorder accompanying sound]
The sound generated in the car is transmitted to the acceleration sensor, and is erroneously recognized as the vibration of the vehicle to affect the event recording. For example, the influence is large when music is played at a high volume or when the sound is low. In particular, for example, in a drive recorder integrated radar detector, when the acceleration sensor of the drive recorder is mounted with a part that generates sound in the same housing, for example, a speaker that outputs an alarm sound of the detector, etc. There is a problem that the sound generated in the case wraps around to the acceleration sensor and interferes with the impact detection.

  In this embodiment, in order to solve these problems, a function for adding the opposite phases of sound is provided. As the sound, for example, the sound generated outside is picked up by a microphone, and when the sound is outputted by itself like an alarm sound, the sound to be outputted is used. These sounds are input to a processing unit that generates a reverse phase, and the negative phase generated by the processing unit is added to the acceleration sensor to cancel the sound.

  Another solution is, for example, an alarm sound in a drive recorder integrated radar detector, which suppresses malfunction based on the sound generated by itself, and the generation of the sound is temporary. Control during which no acceleration is detected may be performed during a period of sound generation, such as during an alarm. In this way, the problem can be solved with a simple configuration.

  For example, the influence on the drive recorder function based on the alarm sound in the drive recorder integrated type radar detector affects the recording of environmental sound in the drive recorder as well as the above-mentioned acceleration sensor. The alarm sound of the detector goes around to the microphone of the drive recorder and interferes with the recording of the environmental sound. In order to solve this problem, it has a function to add the reverse phase of the alarm sound to the detection signal from the microphone.

[Device with radio wave emission function integrated with drive recorder]
For example, in a device having a function of emitting radio waves, such as a radar detector or a moving object detection Doppler sensor, a directional antenna is provided. It is preferable to arrange so that the imaging center of the camera of the drive recorder and the radiation axis of the directional antenna of the device are aligned. In this case, the radiation direction of the invisible radio wave is matched with the image, and hence the installation may be appropriate.

  Furthermore, the radiation angle of the directional antenna may be arranged so as to be wider than the angle of view of the camera. In this way, it can be recognized that radio waves are flying within the range of the video shot by the camera. It is good because the case becomes compact. Desirably, the directional antenna is arranged so that the half-value angle of the directional antenna is wider than the wide angle of view of the camera. If the radiation angle and the half-value angle are the same, it can be understood that the range of the video captured by the camera is the boundary between them. For example, if the directional antenna 93 is a patch antenna, the patches 93a and the camera 8 constituting the directional antenna 93 are preferably arranged as shown in FIG.

[Data communication method]
The various types of radar detectors described above, for example, update firmware or update / update POI data related to an alarm target. It is a communication device that uses a communication system that manages firmware upgrade data communication and normal communication with different charge systems, and POI data and the like may be transmitted by the firmware update data communication. For example, if there is a limit on the capacity that can be sent once in the data communication for firmware upgrade, and if the data capacity of the data for firmware upgrade to be transmitted is less than the limit and there is enough capacity, POI data may be sent together.

  For example, a system that distributes POI data that is regularly distributed from a manufacturer, etc., such as monthly, and POI data that is based on a posting. The POI data that is periodically distributed is transmitted by an existing method such as WiFi, while being posted. The based POI data may be configured to be transmitted by LPWA.

  In this way, the posted POI data can be transmitted in real time using LPWA. The POI data that is regularly distributed does not have real-time characteristics and has a large data size, and therefore is transmitted using, for example, WiFi or the like without using LPWA.

  Since LPWA has a small amount of data to be delayed at one time, it is difficult to send data for the whole country, and it is better to narrow down based on surroundings and posting date and time. For example, when acquiring POI data of a post, the radar detector sends the position information of the current location to a server that manages the POI data of the post, and the server extracts POI data around the current location that has been sent, Send to the radar detector. The radar detector acquires and stores the transmitted POI data, and thereafter adds it to the alarm target when performing the GPS alarm. If the POI data of the post extracted and sent by the server is limited to the latest registered one, for example, today, the transmission data may be small.

  The acquisition timing of the POI data of the post, for example, sends the location information of the current location to the server every fixed time (for example, 10 minutes), the server has POI data around the acquired current location (for example, radius 5km, 10km etc) It is good to do it regularly, as if returning. For example, when the engine is started, the current position is sent to the server, and the server is within a travelable distance of one hour (for example, within 100 km). Posting POI data is sent, and the radar detector sends the current position again after a certain period of time. Hereinafter, the transmission span can be extended by repeating.

When the engine starts, it sends POI in a relatively wide range considering the movement of the expressway, recognizes the movement distance and movement direction from the previous current position data after the second time, and moves in the next fixed time And post the POI data of posts within the predicted range. In this way, by transmitting unnecessary data, it is possible to reduce the increase in communication capacity and transmit necessary and sufficient POI data.
Instead of sending all POI data in LPWA, it is better to send only important POI data such as enforcement in LPWA. When all POI data is sent, it is close to 2M, for example, and it is difficult to send it by LPWA. Therefore, by sending only important POI data such as a control, the important POI data can be surely transmitted with priority and received by the radar detector.

  Important POI data should be sent more frequently than periodic updates, and all POI data should be sent when the radar detector is connected via WiFi. All the transmission data at the time of WiFi connection should be sent regardless of whether or not the POI was transmitted in advance. In this way, there is no need to manage the information of the POI delivered earlier, the control is simplified, and when sending by WiFi, it does not matter much even if the total capacity to be sent is large.

  I do not know what time WiFi will be connected. The server side periodically updates, for example, once a month. However, if the WiFi connection is not performed for a long period exceeding the update period, an alarm based on old POI data is not preferable. Therefore, important POI data is actively transmitted using LPWA.

[Lane notification function]
The various radar detectors described above associate and record lane information of several lanes with a predetermined road such as a main road. The radar detector may be provided with a function of identifying a road currently being traveled from the current position information and reporting lane information when lane information such as how many lanes is registered in the road. For example, the number of lanes such as “This road is a lane on one side” or the state of the lane such as “Is a two-way traffic” may be notified by voice.

  In this way, for example, even in situations where you can not see the lane of the road you are running, such as when the road surface is shining due to rain, snow, and the line is shaved, you can see the approximate lane position, It is good because it can reduce travel across lanes. In particular, if you know only the main road in the place where you run for the first time, you can run with confidence. Also, for example, if there are many lanes such as “5 lanes on one side”, if you plan to turn left or right at the next intersection, etc., it is better to change the lane to a lane closer to the one that turns earlier, etc. It is possible to notify useful information for safe driving without changing the lane immediately before the vehicle. In addition, when there are many lanes, right turn lanes and left turn lanes may be provided near intersections, so it is understood that when going straight ahead, it is better to drive in the central lane, and lane change near lane crossings Because there is no need to

[Reverse run warning function]
The various radar detectors and the like described above preferably have a function of causing a sign of entry prohibition to be recognized by image recognition and giving a warning when reverse running. In addition, it is preferable to have a function of registering GPS position coordinates in advance at an expressway entrance / exit, a service area, etc., and determining whether or not the vehicle has passed through the points in order, and issuing a reverse running warning when the vehicle does not pass through in order.

[Event recording linked to GPS data]
In the case of a device having a drive recorder function, an event recording function linked to GPS data may be provided. The target of event recording is, for example, that it is possible to record the event in addition to displaying the warning table and voice on the screen when the reverse running point data is entered into the GPS data and the vehicle runs backward. In particular, in the case where a 360-degree camera or the like has a function for photographing the inside of a car, it is preferable because the situation of the driver at the warning notification of the reverse run can be recorded.

  Also, if the vehicle speed does not become a complete stop at 0 km / h at the temporary stop point, an event can be recorded. Accidents often occur, and events should be recorded even with minor contact with bicycles or pedestrians.

  In addition, when the vehicle speed measurement device such as Orbis passes, if the speed limit is exceeded, it is possible to confirm after the passage by recording the event. Since it is possible to confirm how many kilometers the vehicle has traveled and it is not consistent with the speed when it is photographed by the vehicle speed measuring device, it is good because it is a ground for claiming the actual traveling speed. Also, it is good to record an event when the speed limit has not been exceeded. In this way, it is good because it becomes evidence that the vehicle was traveling within the speed limit.

[Vehicle position correction function for non-positioning using images]
In the case of a long tunnel such as Ohashi JCT, GPS information is not measured, and an alarm based on GPS information can not be made. In such a case, there is a radar detector provided with a function of determining the traveling distance and direction based on the OBD information and estimating the current position, and based on that, performing an approach alarm on the alarm target. In the estimation of the current position based on the OBD information, for example, the alarm position may be slightly shifted by several cm. In order to solve such a problem, for example, video data captured by a camera or other in-vehicle device is recognized as an image, and a video of a characteristic place such as an exit, an entrance, or a branch point in a tunnel is used. It is advisable to provide a function that corrects the vehicle position so that an accurate alarm can be issued. With such a correction function, it is possible to warn at an appropriate position in a tunnel or the like even with a radar detector not connected with the OBD. The current position should be corrected based on emergency exits, electric bulletin boards, and other signs. In this case, when there are a plurality of similar signboards or the like in the tunnel, for example, the number after entering the tunnel is counted to correct the current position.

[Power saving function during parking monitoring]
In the case of a radar detector integrated with a drive recorder, the power ON / OFF is the same. For example, when the power is turned ON when the engine is started, both the drive recorder function and the radar detector function are activated. The power of the main unit is turned off and the drive recorder function and the radar detector function stop. In such a case, for example, if parking recording is performed with a drive recorder integrated type radar detector, the power of the main body continues to be ON even when the vehicle is parked, so that both the drive recorder function and the radar detector function operate. The problem is that battery consumption is increased.

  Therefore, in this embodiment, for example, a function of suppressing power consumption by turning off the screen of the display unit may be provided. In addition, it is preferable to provide a function of suppressing power consumption without turning off a reception function such as radio or radar wave and performing an operation of only the drive recorder without performing an alarm.
