Description

The present invention relates to electronic devices and programs.

As one of the electronic devices, there is a microwave detector (radar detector) that detects microwaves in a predetermined frequency band emitted from a speed measuring device installed around the road and outputs an alarm. In addition, some speed measuring devices cannot be detected by the microwave detector. As an example, as is called a loop type, there is a device in which a loop-shaped coil is embedded in the ground to detect that a vehicle passes over the coil and also to determine the vehicle speed. In addition, there are some that detect the speed of the vehicle by using light other than microwaves. Therefore, when the installation position information of the speed measuring device is stored in advance and the current position approaches the stored installation position using GPS (Global Positioning System) information (when a predetermined relationship is reached), the micro is used. There is also an electronic device that issues an alarm regardless of the presence or absence of wave detection (Patent Document 1).

This type of electronic device is provided, for example, with a flat rectangular case and is installed on a dashboard or the like. A display unit is provided on the front surface of the installed case (the surface facing the rear of the vehicle (driver side)). The above alarm is performed by outputting alarm information composed of images, videos, characters, etc. to the display unit when a predetermined event occurrence condition / alarm condition is satisfied. In addition, a speaker is built in the case, and alarm information using sound is output from the speaker. The predetermined event occurrence conditions are, for example, that the distance between the current position and the alarm target reaches a predetermined reference distance (for example, 2000 m, 1000 m, 500 m, etc.), and that a predetermined microwave, radio wave, or the like is received. There are cases. Then, the alarm is "500 m ahead, XX." (XX indicates an alarm by voice such as information (loop coil, etc.) that identifies the alarm target, and corresponds to the type of alarm target on the display unit. It displays an animated image, a live-action image of each alarm target, the name of the type of alarm target (alarm name), and the remaining distance.

Japanese Unexamined Patent Publication No. 2008-64588

The alarm associated with the occurrence of a conventional event is issued for one alarm target determined according to a predetermined rule. The predetermined rule includes, for example, setting a priority for each type of alarm target and selecting an alarm target having a high priority, for example, selecting an alarm target closest to the current position. Further, when they are combined and, for example, there are a plurality of alarm targets having the same high priority, the alarm target closest to the current position may be selected among them.

However, there are many cases where there are multiple alarm targets that are candidates for alarm, and if only one alarm target uniquely determined by the above rule is notified, it is possible to know the existence of other alarm targets. Will be delayed. In addition, one alarm target determined by the rule is not always the one that the user wants to know with the highest priority. Therefore, it could not be said that sufficient information was provided.

In addition, there are various standby screens to be displayed on the display unit when no event has occurred, and one of them is a standby screen that displays a map of the area around the current position (hereinafter, also referred to as "Map screen"). .) There is. When a predetermined animation or live-action image is displayed when an event occurs while the Map screen is being displayed, for example, the area where the map is displayed is slid and the animation or live-action image is displayed in the vacant area. Then, as the map moves, the display area becomes smaller, which causes a problem that the map becomes difficult to see. In addition, since the own vehicle icon is usually displayed at the current position on the map on the map, the own vehicle icon slides along with the slide of the area where the map is displayed, which increases the difficulty of viewing.

Further, the conventional alarm content is changed depending on, for example, the type of alarm target. In other words, conventional electronic devices of this type focus on accurately communicating the alarm target, and although they are easy to understand, they lack fun. In addition, there is a risk that the user will be bored due to lack of playfulness.

In order to solve the above-mentioned problems, the electronic device according to the present invention is provided with (1) an alarm function for displaying an alarm display in a character indicating information of an alarm target satisfying an alarm condition on a display unit. As for the alarm function, a plurality of alarm displays can be displayed on the display unit at the same time, and information about different alarm targets is output to each alarm display. By doing so, when there are a plurality of alarm targets that satisfy the alarm conditions, the information about the plurality of alarm targets is output to different alarm displays, so that the alarm target that the user wants to see most or is interested in can be selected. It is preferable because it can be known. Further, this alarm display may be superimposed on the standby screen displayed on the display unit when, for example, the alarm condition is not satisfied. In this case, the standby screen is used as it is as the background at the time of alarm. In addition, it is advisable to output a plurality of alarm displays by superimposing them on another alarm screen.

(2) Of the plurality of alarm displays, the alarm display that displays the information of the alarm target having a high priority may be a conspicuous display mode. In this way, when the alarm displays for a plurality of alarm targets are displayed at the same time, it is preferable that the user naturally easily sees the alarm display for the alarm target having a high priority.

(3) Of the plurality of alarm displays, the alarm display that displays the information of the alarm target having a high priority is set to be a conspicuous display mode, and the conspicuous display mode is to make the display of the alarm display a conspicuous red color. It may be at least one of the above when they are arranged one above the other. For the display of the alarm display to be conspicuous, for example, the frame or ground pattern that specifies the color of the characters or the area of the characters may be reddish.

(4) The alarm target may be divided into a plurality of groups and stored based on the type of the alarm target, and the plurality of alarm displays may be associated with the plurality of groups. The grouping is based on, for example, the type of alarm target, and the same type of alarm target belongs to the same group, so that information about different types of alarm targets is displayed on each alarm display. Therefore, the plurality of alarm displays are not filled with information about the same type of alarm target, and there is a high possibility that the type of alarm target that the user wants to know is displayed. Further, for example, when the priority is set for each type of alarm target, it is preferable that the types of alarm targets having the same priority belong to the same group. By doing so, even a low-priority alarm target is displayed as an alarm display, so that it is possible to provide a wide range of information to the user without omission.

(5) The display position of the plurality of alarm displays in the display area of the display unit may be fixed. By fixing the display position, the user can predict the appearance position of the alarm display. Therefore, for example, if the user remembers the position of the alarm display on which the alarm target that he / she wants to know is displayed, he / she can instantly see the display position of the alarm display and acquire the information.

(6) The alarm display may be arranged on the left and right sides of the display area of the display unit so that the left and right alarm displays are arranged so as to be staggered vertically. By staggering them, they are lined up neatly and are easy to see.

(7) When the number of alarm targets satisfying the alarm condition is smaller than the maximum number of alarm displays that can be displayed, the number of display of the alarm display may be the number of alarm targets satisfying the alarm condition. In this way, the blank alarm display area where information is not displayed is not displayed. For example, when the alarm display is displayed on top of the screen displayed in the display area of the display unit, the alarm display is displayed. It is preferable because the screen drawn below is not hidden by the blank alarm display and becomes invisible or difficult to see. In particular, for example, in order to make the area of the alarm display easier to see, it is difficult to see that there is a blank alarm display when the area is surrounded by a frame or the area is painted with a ground pattern of a predetermined color or pattern. It is preferable because it increases the amount of noise.

(8) A map display function that displays map information around the current position on the display unit, and map information displayed by the map display function when displaying an alarm image related to an alarm target that satisfies the alarm conditions. It is preferable to display the alarm image on top of the map information without sliding the display area of. The warning image includes, for example, an animation or a still image associated with the type of the warning target, a live-action image obtained by capturing an individual warning target, and the like.

By doing so, the display area of the map displayed area does not shrink or move in a predetermined direction, so that the display area of the map to be output can be secured while remaining large. Therefore, the map is easy to see. Also, when the own vehicle icon indicating the current position is displayed on the map, when the map is slid, the own vehicle icon also slides and is displaced. Also, the time to display this type of alarm image is often relatively short. Then, if the display area of the map information is changed and the own vehicle icon is also displaced in such a short period of time, it becomes difficult to see, but according to the present invention, such a situation does not occur and it may be easy to see. Further, since the warning image is superimposed on the map and output and displayed, the area for displaying the warning image can be used, for example, the entire screen of the display unit. As a result, the size and shape of the alarm image can be increased, and if there is movement, the movement can be increased, making it easier to see, and intuitively understanding the type of alarm target. It's okay.

(9) It is preferable that the transmittance of the alarm image can be changed. By changing the transmittance, for example, the alarm image blinks, so that there is an impact and the user's attention can be obtained. Further, for example, it is preferable to make the alarm image appear on the screen from a substantially transparent state, because it can give more impact and notify the user of its existence. Furthermore, for example, if the size of the alarm image is increased, many parts of the map displayed below it will be hidden, but by increasing the transmittance, the user can see the map information below while displaying the alarm image. It is preferable because it can be shown.

(10) The alarm image has an animation main body portion for specifying the type of the alarm target and a distance gauge arranged around the animation main body portion, and the distance gauge is a distance to the alarm target. It is preferable to divide the section into a plurality of sections according to the distance to the alarm target and display the plurality of sections in different colors. This is preferable because it is possible to know the approximate remaining distance and the degree of approach by looking at the color displayed on the distance gauge. Further, it is preferable that the animation main body is, for example, an object in which the alarm target is expressed in 2D or 3D, because the type of the alarm target can be intuitively understood. Further, this distance gauge may also be applied, for example, to be arranged around a main body image element composed of a still image corresponding to the type of alarm target.

(11) The content of the alarm to be displayed when the alarm condition is satisfied may be determined based on information other than the type of the alarm target. The alarm content output when the alarm condition is met is determined based on information other than the type of the alarm target, not the alarm content related to the alarm target that meets the condition, so it is novel and surprises the user. be able to. By appropriately devising the content of the alarm, it is possible to exert a fun and healing effect to the user, and it is possible to surely inform the user that there is an alarm target that satisfies some alarm condition.

(12) Information other than the type of the alarm target is information about the current time, and the alarm content may be an animation specified from the information about the current time. Information about time includes time, time zone, day and night, date, month, season, and the like. Especially in Japan, there are four seasons, and Japanese people experience various seasons, so it is advisable to use the animation that suits the four seasons as the warning content based on the time of the four seasons. By doing so, it is possible to give the user a feeling of comfort in each season, such as a healing effect and a feeling of exhilaration, and it is possible to entertain. Also, for example, the user's mood differs between day and night, such as being active or feeling better during the day, while being calm at night, so the animation to be played differs depending on the day and night. By doing so, for example, it becomes something that suits the user's mood and can be entertained by the user, which is preferable.

(13) It is preferable to have a function of notifying the type of alarm target that satisfies the alarm condition. Such a function of leaving it unattended may be realized, for example, by displaying character information or the like on a character alarm unit provided in the display unit or outputting voice. This is preferable because the type of alarm target can also be recognized.

(14) The standby screen to be displayed on the display unit when the alarm condition is not satisfied may be determined based on the current date and time information. In particular, by fusing with the invention described in (12), the corresponding animation at the present time becomes more alive, which is preferable.

(15) When the second alarm condition specified separately from the normal alarm condition is satisfied, the alarm content different from the alarm content output when the alarm target satisfying the second alarm condition satisfies the normal alarm condition is special. It is advisable to give a warning. The second alarm condition is either a normal alarm condition and a condition to be added to it, that is, a condition to satisfy the normal alarm condition and further to be added, or a case where the second alarm condition is set separately from the normal alarm condition. There is.

(16) The special alarm may output a special animation before the normal alarm is given. In the embodiment, the special animation has, for example, that the screen is cracked by waves (for example, FIGS. 17 (a) to 17 (c)) and the display is disturbed (noise in FIG. 19 (a), FIG. 20 (a)). (Ice breaks, etc.), is sucked into a black hole (Fig. 20 (e)), the screen disappears (Fig. 19 (b), Fig. 21 (b)), and cooperates with an optical tube (Fig. 19 (c), It corresponds to FIG. 21 (c)) and the like. By making a special animation, the user can intuitively understand what happened, and the alarm after that can be watched. In addition, it is good that the user can be entertained by displaying an animation that is not normally seen.

(17) The special alarm may output an animation that makes it difficult to see the display on the display unit. In the embodiment, the fact that it is difficult to see means that, for example, the display of the display unit is disturbed (noise in FIG. 19 (a), ice in FIG. 20 (a) is broken, etc.), a black hole (FIG. 20 (e)), and the like. handle. Similar to the special animation notice described above, the screen becomes difficult to see for a moment, and by playing an unusual animation, the user can pay attention to the screen. In particular, if the screen becomes difficult to see for a moment, the user can expect emotions such as "what happened?", And if it becomes difficult to see, the effect of looking at the screen better can be expected.

(18) The special alarm may be restored after the state is such that an abnormality has occurred. For example, in order to give a feeling of failure or power off, for example, the display unit may be turned off in all black, or the CRT television may be turned off to output a sound effect. By making it look like an abnormality has occurred, the user is surprised for a moment and pays attention to what happened to the in-vehicle device. Then, since it returns after that, the user can see the alarm while paying attention to the in-vehicle device.

(19) An optical tube having a light emitting portion connected to the end thereof is provided, the optical tube shines by the light of the light emitting portion, and the optical tube is arranged at a position where the light emitted from the optical tube can be seen by the driver. , The special alarm may utilize the light emitted from the optical tube. The use of light may mean that light is emitted from an optical tube, for example, when a normal alarm is being given.

The optical tube includes a core material and a clad material formed so as to cover the outer periphery of the core material. Unlike optical fibers used for optical transmission, the interface between the core material and the clad material is irregular in structure. Therefore, the light incident from the end face propagates while repeating total reflection at the interface between the core material and the clad material, and gradually leaks from the side surface due to the structural irregularity of the interface, so that the side surface shines. This optical tube is also referred to as, for example, a side leakage type silicone optical fiber. By forming the core material and the clad material using, for example, an elastomer having a different refractive index (for example, the core material has a high refractive index and a highly transparent elastomer, and the clad material has a low refractive index transparent elastomer), the optical tube has high elasticity. It is flexible and can be bent or bent at any position.

Visible means that the driver can confirm the light emitted from the optical tube as the light emitting unit emits light. That is, it is not necessary to know the existence of the optical tube when the light is turned off, or it may be visible, but it is particularly preferable to configure the structure so that the presence of the optical tube is not known when the light is turned off. By doing so, it is possible to give an impact at the time of lighting. Further, the optical tube may be exposed to the outside, but it is particularly preferable to arrange a transparent / translucent cover member or the like that transmits various kinds of light on the portion facing the driver to cover the optical tube. .. Even if the optical tube is covered with a cover member or the like, it is sufficient that the light emitting optical tube can be visually recognized from the driver side when the optical tube emits light. The light emitting unit may be, for example, a single color or a full color output unit. A full-color output is preferable because it has a wide variety of color development states.

Then, the light emitted by the light emitting unit is incident on the optical tube from the end of the optical tube, and a part of the light is emitted from the periphery of the optical tube to the outside while traveling inside the optical tube. Since the light shines along the shape of the optical tube, the light emitted from the optical tube can be visually recognized by the driver by arranging the optical tube at an appropriate position on the front surface facing the driver of the electronic device.

The optical tube shines along the shape of an electronic device by attaching it to an electronic device in any straight or curved shape. Therefore, it is not a point like a lamp, but a light emitting source having a certain length. Further, unlike the display module, a driver or the like corresponding to the light emitting position is not required, so that it can be arranged near the peripheral edge of the electronic device, for example.

(20) The special alarm may be controlled so that the display object output to the display unit and the light of the optical tube are related to each other. The display object may be, for example, a predetermined picture / motif, a character (“X” in the embodiment), or the like. By fusing the display unit and the optical tube, the display area becomes larger than the display screen of the display unit, and it is possible to give a more impactful, novel, and unexpected alarm.

(21) When passing through the alarm target, it is advisable to cut in an image showing the passing state. By cutting in a predetermined number of images, it is possible to give an impact to the user and more reliably notify the user that the image has passed. For example, it is advisable to output an image with the cut-in when an alarm is given by a normal animation. This cut-in may be used as a special alarm.

(22) It is advisable to determine the traveling situation when passing through the warning target and output the screen of the determination result. By outputting the determination result screen, it is possible to more reliably notify the user that the alarm target has been passed. Furthermore, since the running condition at the time of passing is determined, it is game-like and more interesting. Further, it is good that the driver can be expected to drive carefully so that the screen of the better determination result is output. (23) The traveling condition may be a deviation between the speed limit and the traveling speed.

(24) A function for notifying that public control information has been announced at the current location, and according to a display request from the user, the public control information display unit showing the public control information in a static text is displayed superimposed on the display screen. It is good to have a function. In the embodiment, the notification function performs a process of blinking the warning lamp unit 71. Further, the notification function is not limited to displaying characters and other display elements on the display unit, and notification by sound is also good. Since the public control information is displayed as a static text, the user can check the content of the public control information at any time while the public control information is being displayed. The stationary state does not mean that the display position of each character moves like scrolling, but the display position of the character does not change. Therefore, for example, when the characters are continuously displayed at the same position, the display position is the same, and the characters are repeatedly displayed / hidden to make the characters blink, which is also included in the stationary state. It can also be said that the text is displayed with the display position of the characters fixed. Users who do not want to see the public control information or who do not need to see it because they are informed that there is public control information and the actual contents of the public control information are notified after waiting for instructions from the user, etc. It is preferable because it can suppress the provision of information unnecessary for the user and eliminate unnecessary information for the user. Further, when the public control information is displayed as text, it is performed at the request of the user, so that the public control information may be displayed using a relatively large area such as the full screen of the display unit, and the information display is easy to see. You can.

(25) A standby screen display function for displaying a standby screen to be displayed on the display unit when the alarm condition is not satisfied is provided, and the standby screen display function indicates the direction and magnitude of acceleration applied to the vehicle to indicate the vehicle. It is good to display it with an acceleration gauge placed around the vehicle object. In this way, the user can intuitively understand the state of acceleration at a glance, which is preferable.

(26) It is preferable to determine the display position of the acceleration gauge in the outer periphery of the vehicle object based on the direction of the acceleration applied to the vehicle, and determine the gradation display of the acceleration gauge based on the magnitude of the acceleration. The direction of acceleration can be intuitively understood from the display position on the acceleration gauge, and by expressing the magnitude of acceleration with a gradation, it is good because it is clean, easy to understand, and interesting.

(27) It is preferable to have a standby screen display function for displaying a standby screen to be displayed on the display unit when the alarm condition is not satisfied, and the standby screen display function may display CN values of a plurality of GPS satellites in a graph. By displaying the graph, it is preferable to intuitively understand the magnitude of the CN value of a plurality of GPS satellites currently being received, and to know the number of GPS satellites that can be received. In this case, for example, if the graph display is a bar graph and the display color of the bar line is changed based on the size of the CN value, the CN value is large depending on the color in addition to the area of the display area. That is, it is preferable because it is possible to understand the appropriateness of the reception status of radio waves from GPS satellites. In particular, if the level sufficient for positioning the CN value is divided into green and blue, the level that is not enough or insufficient for positioning is divided into red, and the intermediate level is color-coded into yellow. It is good because it is related to the color of the traffic light and it is easy to understand the state of the reception status.

(28) The standby screen display function for displaying the standby screen to be displayed on the display unit when the alarm condition is not satisfied is provided, and the standby screen display function scores a plurality of predetermined items based on driving data. The overall result of the operation is displayed based on the scoring of the plurality of items, and the overall result is displayed so that the higher the overall evaluation, the better the user's mood. It is preferable to use a suitable display mode. This is preferable because it makes the user feel better and encourages the user to drive with a relaxed feeling. Further, it is good that the user, that is, the driver, tries to drive in a display mode that makes him feel better, and can promote safe driving and eco-driving. In addition, such display of the total result is preferable because it is game-like and playful.

(29) The display of the overall result may be such that the lower the overall evaluation, the worse the user feels. In this way, if the overall result is poor, the display mode is not preferable for the user. Therefore, the user makes an effort to drive so as not to have such a display mode, and as a result, safe driving and eco-driving It is good because it can encourage. In addition, such display of the total result is preferable because it is game-like and playful.
(30) The program of the present invention is a program for realizing the function as an electronic device according to any one of (1) to (29) in a computer.

According to the present invention, the alarm desired by the user can be performed.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. These drawings are used to illustrate the technical features that may be employed in the present invention. The configuration of the device and the like described are not limited to that, but are merely explanatory examples.

[Basic configuration of electronic devices]
1 and 2 show a configuration of a radar detector, which is an embodiment suitable as an electronic device constituting the system of the present invention. The radar detector 1 is provided with a thin rectangular case 2, and is attached and fixed on the dashboard of a vehicle or the like by using a bracket 3 attached to the lower part of the back surface of the case 2.

A display unit 5 is provided on the front surface of the case 2 (the surface facing the rear of the vehicle (driver side)). The display unit 5 is composed of a color TFT liquid crystal display. A touch panel 6 for detecting which part of the display unit 5 is touched is provided on the display unit 5. Further, a volume adjustment button 7 is arranged on the right side of the front surface of the case 2, and various work buttons 8 are arranged on the left side of the case 2.

A card insertion slot 9 for mounting a memory card as a removable recording medium is provided on the right side surface of the case 2, and 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 takes in the data stored in the mounted memory card 11 inside. More specifically, the data stored in the memory card 11 has updated information such as new alarm target information (position information such as latitude and longitude, type information, etc.), and the updated information is transmitted via the control unit 18. It is stored (downloaded) in the database 19 built in the device, and the data is updated.

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

The GPS receiver 13 is arranged inside the upper center on the back side of the case 2, and the microwave receiver 14 and the wireless receiver 15 are arranged next to the GPS receiver 13. The GPS receiver 13 receives a GPS signal from a GPS satellite and outputs current position (latitude / longitude) information. The microwave receiver 14 receives a microwave having a predetermined frequency emitted from the speed measuring device. The radio receiver 15 receives VHF and UHF band radio waves and the like for traffic control communication. A speaker 16 is built in a predetermined position in the case 2.

A mini USB connector 12 is arranged below the back side of the case 2. The mini USB connector 12 is for connecting a cigar plug cord (not shown), and can be connected to a cigar socket of a vehicle via the cigar plug cord to receive power supply.

Case 2 contains an OBD adapter 21 that is detachably attached to the OBD-II (II is the Roman numeral "2", hereinafter "OBD-II" is referred to as "OBD2") connector mounted on the vehicle. Be connected. The OBD2 connector, also referred to as a failure diagnosis connector, is connected to the ECU of the vehicle and periodically outputs various vehicle information. Therefore, by connecting the OBD adapter 21 and the OBD2 connector on the vehicle body side, the control unit 18 periodically acquires various vehicle information.

The vehicle information includes information on the mileage of the vehicle, the vehicle speed of the vehicle, the injection injection time, the amount of intake air, the remaining fuel, and the like. Residual 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 on a regular basis and recording the timing when the change occurs between the previous remaining fuel and the current remaining fuel, it is consumed from the previous change to the current change. It can be said that the fuel used is 0.5 liters. In addition, some information on fuel consumption (information on lifetime fuel consumption, current fuel consumption, instantaneous fuel consumption, etc.) is output on a regular basis.

Further, the above-mentioned OBD adapter 21 is detachably linked to the connection terminal 23 provided in the case 2. When the vehicle information from the OBD2 connector is unnecessary, removing the OBD adapter 21 suppresses the wiring from being cluttered on the dashboard or the like, and makes the surroundings of the radar detector clear.

The case 2 is provided with an acceleration sensor (G sensor) 25 and a gyro sensor 26. The acceleration sensor 25 detects the acceleration of the vehicle, and obtains the acceleration in two directions, the front-rear direction and the lateral direction of the vehicle. The gyro sensor 26 integrates the angular velocities, so that the control unit 18 obtains the traveling direction of the own vehicle on the map.

The control unit 18 is a microcomputer including a CPU, ROM, RAM, non-volatile memory, I / O, etc., and is connected to each of the above-mentioned units as shown in FIG. The control unit 18 is a driver based on information input from the above-mentioned various input devices (touch panel 6, GPS receiver 13, microwave receiver 14, wireless receiver 15, acceleration sensor 25, gyro sensor 26, etc.). Information to be notified to is created, and the information is output using an output device (display unit 5, speaker 16, etc.). These basic configurations are basically the same as the conventional ones.

The function of the radar detector 1 of the present embodiment is realized by being stored in the NAND Flash memory of the control unit 18 as the firmware executed by the CPU of the control unit 18, and being executed by the CPU of the control unit 18. The firmware stored in the NAND Flash memory can be updated by the new firmware stored in the memory card 11.

"Notification using optical tube"
Case 2 has a substantially gourd shape that is horizontally long when viewed from the front. The substantially gourd shape referred to in the present embodiment is a shape in which two circles arranged on the left and right sides are connected to each other, and the connecting portion is provided with a constricted portion recessed toward the center. In this embodiment, the diameters of the circles on both the left and right sides are equalized, and the distance from the center in the longitudinal direction to the center of each circle is also equalized. The front surface of the case 2 has a symmetrical shape in the vertical and horizontal directions. Further, the display unit 5 has a rectangular shape and is arranged in the center of the front surface of the case 2.

The optical tube 20 is arranged at a predetermined position on the front surface of the case 2. The optical tube 20 includes a core material and a clad material formed so as to cover the outer periphery of the core material. Unlike optical fibers used for optical transmission, the interface between the core material and the clad material is irregular in structure. Therefore, the light incident from the end face propagates while repeating total reflection at the interface between the core material and the clad material, and gradually leaks from the side surface due to the structural irregularity of the interface, so that the side surface shines. This optical tube is also referred to as, for example, a side leakage type silicone optical fiber. By forming the core material and the clad material using, for example, an elastomer having a different refractive index (for example, the core material has a high refractive index and a highly transparent elastomer, and the clad material has a low refractive index transparent elastomer), the optical tube has high elasticity. It is flexible and can be bent or bent at any position. The optical tube shines along the shape of an electronic device by attaching it to an electronic device in any straight or curved shape. Therefore, it is not a point like a lamp, but a light emitting source having a certain length.

The optical tube 20 is arranged along the peripheral edges on both the left and right sides of the front surface. Each optical tube 20 has an arc shape, and one end of the optical tube 20 is arranged so as to approach the upper side of the display unit 5, and the other end of the optical tube 20 is arranged so as to approach the lower side. The optical tube 20 is arranged so as to wrap around the outside of the volume adjustment button 7 and the work button 8.

As shown in FIG. 3, light emitting portions are connected to both ends of the optical tube 20. For the light emitting unit, for example, a full-color LED 22 is used. The light of a predetermined emission color emitted from the full-color LED 22 is incident on the optical tube 20 from the end portion of the optical tube 20. A part of the incident light leaks out from the periphery of the optical tube 20 while traveling in the optical tube and is emitted. Light is emitted from the entire optical tube 20 and shines in a predetermined color along the shape of the optical tube 20. Since the optical tube 20 is arranged on the front surface of the case 2 facing the driver, the light emitted from the optical tube 20 can be visually recognized by the driver.

Further, the front surface of the case 2 has an opening along the outer peripheral edge of a substantially gourd shape, and a transparent cover 24 is attached to the opened portion to close the opening on the front surface thereof. In the transparent cover 24, the display unit 5, the volume adjustment button 7, the work button 8, and the area facing the optical tube 20 remain transparent so that the display object of the display unit 5 and the light from the optical tube 20 can be emitted. It emits to the front and the outside. Therefore, as described above, the driver can visually recognize the display object of the display unit 5 and the light from the optical tube 20. In the transparent cover 24, the display unit 5, the volume adjustment button 7, the work button 8, and the portion outside the region facing the optical tube 20 are smoked on the inner surface to make it difficult to see the inside of the case 2.

FIG. 3 shows a schematic diagram of the optical tube 20, the full-color LED 22, and the display unit 5. Full-color LEDs 22 are connected to both ends of the optical tube 20. The full-color LED 22 connected to one end of the optical tube 20 located on the upper side of the display unit 5 is the first full-color LED 22a, and the full-color LED 22 connected to the other end of the optical tube 20 located on the lower side of the display unit 5 is the second full-color LED 22a. Let it be LED22b. In the following description, when it is not necessary to distinguish each of the hula color LEDs, they are collectively referred to as the full color LED 22, and when they are distinguished, either the first or the second is described. The full-color LED 22 is arranged on the back side of the display unit 5. When the driver sees the radar detector 1 from the front, the full-color LED 22 is hidden behind the display unit 5.

The control unit 18 controls the light emission of the first full-color LED 22a and the second full-color LED 22b. As an example of controlling light emission, control is performed so that each light emission color is different. The light of the first emission color emitted by the first full-color LED 22a is incident on the optical tube 20 from one end of the optical tube 20, and while traveling toward the other end in the optical tube 20, a part of the light is part of the optical tube 20. It emits light from the surroundings to the outside. Therefore, the first section K1 from one end of the optical tube 20 to a point separated by a predetermined distance shines in the first emission color. On the other hand, the light of the second emission color emitted by the second full-color LED 22b is incident on the optical tube 20 from the other end of the optical tube 20, and a part of the light enters the optical tube 20 toward one end. It emits light from the periphery of 20 to the outside. Therefore, the second section K2 from the other end of the optical tube 20 to a point separated by a predetermined distance shines in the second emission color. The respective lights incident from both ends of the optical tube 20 collide with each other at a predetermined position in the optical tube 20 and are mixed. In the third section K3 where both lights are mixed, it shines in an intermediate color between the two emission colors.

Assuming that the first emission color is, for example, red and the second emission color is, for example, blue, the first section K1 shines red, the second section K2 shines blue, and the third section K3 shines purple. The color of the light near the boundaries of the adjacent sections changes gradually. The position of the third section K3 is determined by the difference between the emission intensity of the first full-color LED 22a and the emission intensity of the second full-color LED 22b. When both emission intensities are equal and there is no difference in emission intensity, the distances from both ends are equal to the center position in the length direction. When the light intensity of the second full-color LED 22b is stronger, the third section K3 becomes from one end of the optical tube 20 and the first section K1 becomes shorter as shown in FIG. 3 (b), and the second full-color LED 22b. When the light intensity of is stronger, as shown in FIG. 3B, the third section K3 becomes from one end of the optical tube 20 and the first section K1 becomes shorter, and conversely, the light intensity of the first full-color LED 22a. When is stronger, as shown in FIG. 3C, the third section K3 becomes longer than the other end of the optical tube 20, and the second section K2 becomes shorter. Therefore, for example, the control unit 18 gradually brings the light intensity difference obtained by subtracting the light intensity of the second full-color LED 22b from the light intensity of the first full-color LED 22a to zero from a large negative value, and then gradually approaches a positive value. When the control is performed to increase the number of light sources, the position of the third section K3 that shines in the neutral color moves from one end to the other end of the optical tube 20. Along with this movement, the region shining with the first emission color of the first section K1 gradually extends, and the region shining with the second emission color of the second section K2 gradually shrinks.

In the control performed by the control unit 18 so as to have different emission colors, for example, at least one of hue, saturation, and lightness is made different. It is not limited to those having different hues such as red and blue described above. For example, the color of (255,0,0) and (128,0) when R, G, and B are expressed in 256 gradations, respectively. , 0) Even if only the R component is used, the emission color will be different even if the R value is different.

[Collaboration / fusion of optical tube and display unit]
Notification / alarm using the optical tube may be performed from the single light emission of the optical tube 20 or may be performed together with the display unit. The control unit 18 may control so that the display object output to the display unit 5 and the light emitted from the optical tube 20 are related to each other. Here, the display object includes, for example, a predetermined picture / motif, characters, or the like. By fusing the display unit 5 and the optical tube 20, the display area becomes larger than the display screen of the display unit 5. The edges of the display module constituting the display unit 5 do not shine due to the driver and the like. Therefore, even if the size of the display unit 5 is increased, it is difficult to use the entire front surface of the case 2 of the radar detector 1, particularly the immediate vicinity of the outer peripheral edge, as the display area. Further, since the front surface of the case 2 faces the driver, various switch buttons (for example, volume adjustment button 7, work button 8, etc.) are arranged as one of the user interfaces. The display area of the display unit 5 is narrower than the outer peripheral edge of the radar detector 1. Further, assuming that the shape of the outer peripheral edge of the front surface is a non-rectangular shape including a curved portion like a gourd shape as in the present embodiment, between the peripheral edge of the rectangular display unit 5 and the outer peripheral edge of the radar detector 1. There will be a gap.

On the other hand, if the optical tube 20 is used, it can be arranged at the very edge of the peripheral edge of the case of the electronic device. Therefore, the display object can be expressed by using the entire front surface facing the driver of the case. The control in which the display object displayed on the display unit 5 and the light emitted from the optical tube 20 are related may be, for example, symbolizing / expressing a part of the object represented by the display object by the optical tube 20. For example, as schematically shown in FIG. 4A, the character "X" is output to the display unit 5, and both ends of the optical tube 20 and the character "X" are made continuous to generate "∞" as a whole. There is something to express. By connecting the display object output to the display unit 5 (for example, the letter "X") and the light emission of the optical tube in this way, the continuity and sense of unity between the display object output to the display unit and the optical tube can be achieved. It's good because it's stronger and easier to understand. Further, the display object to be output to the display unit 5 is not limited to characters.

In FIGS. 4 (b) and 4 (c), the character "X" is output to the display unit 5, and both ends of the optical tube 20 and the character "X" are made continuous to express "∞" as a whole. An example is shown. In the example shown in FIG. 4B, the control unit 18 emits the full-color LEDs 22 connected to both ends of the optical tube 20 in a predetermined color (for example, blue) so that the entire optical tube 20 glows blue. do. Further, the control unit 18 outputs X represented in a predetermined color (for example, blue) to the display unit 5. Then, both ends of the optical tube 20 are connected to the letter X to be output to the display unit 5. Further, the control unit 18 draws the discharge so that the light runs around the straight line constituting the “X”. The portion of the discharge around the straight line constituting "X" may be a still image, but it is preferable to make a moving image as if the discharge / light is running, because it gives a sense of presence. Further, it is preferable to output the discharge sound such as "crunchy" and "chatter" from the speaker 16 according to the discharge operation. In addition, it is advisable to output the sound of lightning and the sound of lightning strikes in the image of lightning. The discharge portion displayed around the portion of the letter "X" may or may not appear stronger. Further, as shown in FIG. 4 (c), the letter "X" may be eliminated so that the light emission of the optical tube 20 is continued at the discharge portion. That is, the control unit 18 has a discharge connecting the upper end of the left optical tube 20 and the lower end of the right optical tube 20, and the lower end of the left optical tube 20 and the right optical tube. Draw a discharge connecting the upper ends of 20. Discharge is preferable because it gives a more realistic feeling when it is made into a moving image. In this pattern example, it can be said that "X" is expressed by the discharge portion. Further, for example, the flame is expressed by changing the color of the letter "X" to red, orange, or the like.

The control unit 18 performs light emission control for the first full-color LED 22a and the second full-color LED 22b, for example, when a predetermined alarm condition is satisfied. For example, similarly to outputting the alarm information using the display unit 5 described above, the control unit 18 detects the position (latitude / longitude) of the alarm target stored as map information in the database 19 and the GPS receiver 13. The distance between the two is calculated from the current position (latitude and longitude) of the vehicle, and when the calculated distance is less than or equal to a predetermined distance, the light emitting state of the full-color LED 22 is controlled so that the optical tube 20 shines in a predetermined color. To. Further, for example, when the control unit 18 detects a signal corresponding to a microwave in a frequency band emitted from the speed measuring device by the microwave receiver 14, or when a predetermined radio wave is detected by the radio receiver 15. , The light emitting state of the full-color LED 22 is controlled so that the optical tube 20 shines in a predetermined color.

When the optical tube 20 shines in this way, it becomes a light emitting source having a certain length, not a point light source like a lamp or an LED light source. Further, unlike the display module, a driver or the like corresponding to the light emitting position is not required. Therefore, by arranging the radar detector 1 along the outer peripheral edge as in the present embodiment, the display is performed by the conventional display module. Light can be emitted in a manner that cannot be obtained by the unit, which is a new output means utilizing visual recognition. Then, by arranging the optical tube 20 outside the display unit 5, the outside of the display area of the display unit 5 also shines. Therefore, by using the light emitted from the optical tube 20 as one of the alarm information, even if the display unit 5 is small, it is more conspicuous, has an impact on the driver, and has a high surprise effect.

[Modified example of optical tube notification]
In the above-mentioned example, the emission colors of the first full-color LED 22a and the second full-color LED 22b are different, and the difference in light intensity is adjusted to control the movement of the position of the third section K3 that shines in the neutral color. The invention is not limited to this, and various controls are possible. For example, it is preferable to fix the difference in light intensity and control to change the emission color of the first full-color LED 22a and the second full-color LED 22b.

Further, in FIG. 4 described above, the boundary between the optical tube 20 and the display unit 5 is described by connecting them for convenience to explain the cooperation / fusion between the optical tube 20 and the display unit 5. That is, the upper and lower ends of the character "X", which is a display object displayed on the display screen of the display unit 5, are described so as to reach the upper and lower sides of the display unit 5, and are continuous with the tip of the optical tube 20. It is described in. Actually, as shown in FIG. 5, there may be an area in which the display object is not displayed in the area above the upper side of the display unit 5 and the area below the lower side of the display unit 5. Further, even if a display unit 5 of a type in which an undisplayed area does not exist on the upper side of the upper side or the lower side of the lower side is used, for example, a color LED or the like which is arranged on the back side of the display unit 5 by bending the tip of the optical tube 20. By adopting a form of connecting to the light emitting portion, the shining portion of the optical tube 20 may be separated from the peripheral edge of the display portion 5. However, ideally, it is desirable to eliminate the boundary as shown in FIG.

"Basic functions of notification / alarm using display unit 5 etc."
The main information output from the output device of the radar detector 1 is warning 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 position of the alarm target (latitude / longitude) stored as map information in the database 19 and the current position (latitude / longitude) of the vehicle detected by the GPS receiver 13, and the obtained distance is obtained. When the distance is less than a predetermined distance, alarm information is output from the output device (GPS alarm function). Further, for example, the control unit 18 outputs warning information from the output device when a signal corresponding to the microwave in the frequency band emitted from the speed measuring device is detected by the microwave receiver 14 (radar wave warning 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 outputs warning information to make the driver recognize a dangerous place where a traffic accident is likely to occur. As a result, the radar detector 1 can encourage the driver to drive safely. The above-mentioned warning information is an example, and actually, various other warning information is output to the driver. The alarm information includes, for example, visual information composed of predetermined images, videos, characters, etc. output to the display unit 5, and sound / voice output to the speaker 16. The specific content of the alarm 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 the event has not occurred, the control unit 18 displays a predetermined standby screen (standby screen display function). This standby screen display function displays, for example, GPS-based information such as the speed, latitude, longitude, and altitude of the own vehicle detected by the GPS receiver 13 in numerical values, graphs, animations, and other modes, and the GPS receiver 13. A function to display the presence of GPS satellites detected in the above in numerical values, animation, and other modes, and to display numerical values, graphs, animation, and other modes based on the predetermined OBD information and vehicle information acquired by the OBD adapter 21. Is. The standby screen display function also has a MAP display function that accesses the database 19 based on the current position detected by the GPS receiver 13 and reads out and displays the map data stored in the database 19 (FIG. 6A). Etc.).

FIG. 6A shows an example of a display screen output to the display unit 5 by the MAP display function. The control unit 18 reads out the map information of the surroundings based on the current position of the own vehicle from the database 19 and displays it in the main display area R1 showing most of the display screen of the display unit 5. An arrow-shaped own vehicle icon 31 is displayed at the position of the own vehicle on the map. The display position of the own vehicle icon 31 is a predetermined position determined in the main display area R1, and the heading up is fixed, for example, based on the display position of the own vehicle icon 31 (displayed so that the traveling direction is always upward). Display map information as. The display position of the own vehicle icon 31 is, for example, near the center on the lower side of the main display area R1. Further, the control unit 18 searches for the alarm target around the current position based on the position information stored in the database 19, and when the alarm target (POI: “Point Of Interest”) exists in the vicinity, the control unit 18 is on the map. Information indicating the alarm target is superimposed and displayed at the corresponding position. The information indicating the alarm target is, for example, a mark icon representing the alarm target.

The control unit 18 displays the current scale information (scale) in the scale display area R3 set on the left side of the main display area R1. The scale has the own vehicle position as 0 m, and the distance from the own vehicle position to the intermediate position in the vertical direction of the main display area R1 (“250” in the figure) and the distance to the upper position (“500” in the figure). indicate. The unit is "m". When the control unit 18 detects that the main display area R1 has been touched twice in succession, the control unit 18 displays a map scale change button at a predetermined position (a position along the scale display area R3) in the main display area R1 (illustrated). Omitted), change the map scale according to the touch to the map scale change button. That is, the control unit 18 changes the scale of the map displayed in the main display area R1 according to the scale of the changed map scale, and also changes the scale information displayed in the scale display area R3.

Above the main display area R1, an information display unit for displaying predetermined information is provided. This information display unit is superimposed on the map displayed in the main display area R1. The control unit 18 displays map information and various types of information to be displayed on the information display unit by using different layers arranged in a plurality of layers. The information display unit includes a clock display unit 32a, an icon display unit 32b, a vehicle speed display unit 32c, and a compass display unit 32d from the left.

The clock display unit 32a displays the current time. The control unit 18 acquires the current time from, for example, the internal clock or GPS information, and outputs the current time to the clock display unit 32a. The icon display unit 32b displays traffic rules and other status information around the current position, status information regarding the mode in which the device is operating, and the like as icons. The status information around the current position includes, for example, the reception level of GPS radio waves from GPS satellites, whether or not the area is targeted frequently on the vehicle, and whether or not the area is a parking prohibited area. The GPS icon, which indicates the reception level of GPS radio waves, changes the number of antennas displayed according to the reception level to one, two, or three, and in the case of non-positioning where GPS radio waves cannot be received, VPS (Virtual Positioning System). Displays an icon representing a gyroscope indicating. In the on-board aiming frequent occurrence area and the parking prohibited area, when the current position enters the corresponding area, the corresponding icon is turned on, and when the current position goes out of the area or the icon is turned off. As a mode, there is a favorite mode selection for setting the reception sensitivity of radar waves and what to give an alarm. In the figure, in order from the left, GPS radio wave reception level, on-board aiming frequent occurrence area, parking prohibited area, radar wave reception mode ("SE": Super Extra in the figure), favorite mode selection ("MA": manual in the figure) Display each status icon of. The own vehicle speed display unit 32c displays the current vehicle speed of the own 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 GPS radio wave, acquires the vehicle speed information from the vehicle to the OBD adapter 21, and displays the vehicle speed information 32c. Do it by. The compass display unit 32d displays the direction of the vehicle in the traveling direction.

The current position speed limit information regarding the speed limit at the current position is displayed at a predetermined position of the display unit 5. In the figure, the predetermined position is on the lower left side of the main display area R1. Further, the current position speed limit information is an icon 33 having a design imitating a speed limit sign. For example, in the database 19, the speed limit data in which the position information and the speed limit are associated with each predetermined distance is recorded for the road on which the speed limit is set. The control unit 18 accesses the database 19 based on the current position information acquired from the GPS receiver 13, acquires the speed limit of the current position from the speed limit data, and displays the icon 33 corresponding to the acquired speed limit on the display unit 5. Output in place. Further, the MAP display function searches for the alarm target around the current position based on the position information stored in the database 19, and when the alarm target exists in the vicinity, the alarm target is shown at the corresponding position on the map. It also has a function to display information in layers. The information indicating the alarm target to be superimposed and displayed on the map may be, for example, a GPS target icon 35 that specifies the type of the alarm target. As shown in FIG. 7, for example, the GPS target icon 35 has a mode in which characters, symbols, and marks indicating the type and content of the alarm target are arranged in a circle. The colors of the icons are classified into four colors, "red"-> "yellow"-> "blue"-> "green", in descending order of urgency. Furthermore, it is advisable to control the highly urgent "red" and "yellow" icons to blink.

* Alarm output based on the occurrence of an event The control unit 18 executes processing for realizing each function such as a GPS alarm function, a radar wave alarm function, and a radio alarm function according to the event that has occurred. The radar wave warning function is displayed when the microwave receiver 14 detects a signal corresponding to a microwave in a frequency band emitted from a speed measuring device (mobile radar or the like (hereinafter, simply referred to as “radar”)). This is an alarm function that displays an alarm screen for unit 5 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, as shown in FIG. 4, a schematic diagram or a photograph of the radar stored in the database 19 is displayed on the display unit 5 as an alarm screen. At the same time as displaying, the voice data stored in the database 19 is read out, and the voice "Radar. Be careful of speed" is output from the speaker 16.

The wireless alarm function is a function of issuing an alarm when a wireless radio wave emitted by an emergency vehicle or the like is received by the wireless receiver 15 so as not to interfere with the traveling or the like. In the radio alarm function, control radio, car location radio, digital radio, extra small radio, station activity radio, police phone, police activity radio, wrecker radio, heli-tele radio, fire heli-tele radio, fire radio, emergency radio, highway radio , The frequency of the security radio, etc. is scanned, and when the radio is received at the scanned frequency, a schematic diagram indicating that the radio corresponding to that frequency stored in the database 19 for each radio type is received is displayed as an alarm screen. In addition to displaying on the unit 5, the voice data stored in the database 19 for each radio type is read out, and the alarm voice indicating the radio type is output from the speaker 16. For example, when a crackdown radio is received, a voice is output such as "It is a crackdown radio. Be careful of speed."

The GPS alarm function is, for example, a process of executing the standby screen display function at predetermined time intervals (for example, 200 ms intervals) by an event from the timer of the control unit 18, and the current position detected by the GPS receiver 13. It is a function of determining whether or not the alarm condition (predetermined approach relationship) is satisfied by using the alarm target information stored in the database 19, and issuing an alarm when the alarm condition (predetermined approach relationship) is satisfied.

First, to show an example of the type of alarm target, a doze driving accident point, a vehicle speed measuring device (radar type / H system / loop coil / LH system), a mobile vehicle speed measuring area, a speed limit switching point, a control area, Inspection area, ban monitoring area, N system, traffic monitoring system, intersection monitoring point, signal ignoring deterrence system, police station, accident frequent occurrence area, on-board aiming frequent occurrence area, steep / continuous curve (expressway), branch / confluence point ( ETC lane advance guidance (expressway), service area (expressway), parking area (expressway), highway oasis (expressway), smart interchange (expressway), gas station in PA / SA (expressway) ), Tunnels (expressways), highway radio reception areas (expressways), prefectural border announcements, roadside stations, viewpoint parking, etc.

The alarm target information stored in the database 19 is information related to each alarm target, position information including longitude and latitude for specifying the position of the alarm target, and an alarm target useful for the driver to identify the alarm target. There is specific information. In this embodiment, the position information is absolute position information using longitude and 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 target identification information includes type information indicating the type of the alarm target, text information indicating the position of the alarm target, voice information indicating the alarm target, image information indicating the alarm target, and the like. When the voice information or image information indicating the alarm target corresponds to the type information of the alarm target, it is not stored as the alarm target information for each alarm target, but is separately stored in a predetermined storage area as common information. You can also do it. Then, when issuing an alarm, the control unit 18 can read the type information stored as the alarm target information, acquire the corresponding image information, voice information, and the like from the type target, and output the alarm.

Common image information includes image data such as a schematic diagram that makes it easy to understand the type of alarm target. The schematic diagram is also a mark for making it possible to intuitively understand the type of alarm target visually, and for example, there is a vehicle speed device, a police car, a policeman, etc. created as an image in 3D or the like. By drawing and outputting these schematic diagrams to the display unit 5 at the time of notification, the driver can intuitively understand the type and content of the alarm target currently being notified. Then, as will be described later, by drawing the own vehicle icon at the position of the own vehicle on the display area of the display unit 5 and drawing the schematic diagram at the position of the alarm target portion, what position and what It is more preferable because it is possible to intuitively understand whether there is an alarm target.

In addition, the voice information is output from the speaker 16 as voice information, for example, the relative positional relationship such as "It is a highway H system 1 km ahead to the left" and "It is a general road N system immediately ahead", and the type of alarm target. It is the data for. In the above example, voice data showing the relative positional relationship between the current position of the vehicle such as "to the left", "1 km ahead", and "immediately ahead" and the alarm target, and "general road N system" and The voice data for specifying the type and content of the alarm target, such as the "highway H system", is separately managed and stored, and the control unit 18 outputs the voice data in combination when the notification is made.

By separately managing fixed voice information (voice data) according to the type of these alarm targets, it is not necessary to register the same information as the alarm target information of each alarm target, and the memory area is consumed. The amount can be reduced.

Then, for example, during the execution of the standby screen display function of FIG. 6A, the database 19 is periodically accessed based on the current position, and the distance between the loop coil to be alarmed and the own vehicle is stored in the database 19. When the approach warning distance is 2 km, 1 km, or 500 m, the data of the schematic diagram or photograph of the loop coil to be alarmed is read from the database 19 and displayed on the display unit 5, and the database is displayed. The approach notification is performed by reading the voice data stored in 19 and outputting an alarm voice from the speaker 16. For example, when approaching 500 m, as shown in FIG. 3 (c), the same radar scope screen as in FIG. 3 (b) is displayed on the right side of the screen, and the positions of the loop coil, which is the alarm target, and the position of the own vehicle are displayed. In addition to displaying the relationship, the data of the schematic diagram or photograph of the loop coil, which is the alarm target indicating the loop coil, is read from the database 19 and displayed on the display unit 5, and the voice data "500 m ahead loop coil, be careful of speed" is output. It is read from the database 19 and output from the speaker 16.

Further, the database 19 stores map data including road network information. This 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 regulations such as one-way traffic. Furthermore, this road network information stores the position information (latitude and longitude) of the node with the intersection of the roads or the turning point of the road as a node, and also stores the connection relationship of which node the other node to which each node connects. I remember the information shown. Based on the information indicating the connection relationship of each node in this way, adjacent nodes are connected to each other, and the connected nodes form a road link. It should be noted that, unlike the car navigation device, it does not provide guidance to the destination, so there is no detailed data such as display data of facilities, houses, etc., and it is simple data.

[Embodiment 1 of alarm using display unit 5] (simultaneous alarm of multiple types)
As one of the alarm modes of the alarm accompanying the occurrence of the event described above, an alarm function for displaying the information of the alarm target matching the event occurrence condition as an alarm display is provided. This alarm function is a function of displaying, for example, an "alarm name (also referred to as a" target name ")" and a "distance from the current position" as information on the alarm target at a predetermined position of the display unit 5. For example, when the standby screen is displayed, this alarm display is superimposed on the standby screen.

Then, in the present embodiment, it is possible to display a plurality of the alarm displays at the same time. In the present embodiment, the maximum number of alarm displays displayed at the same time is five. Further, the display position of each alarm display is set to a fixed place of the display unit 5. FIG. 6B shows an example of a layout that enables simultaneous display of the five alarm displays of the present embodiment. As shown in the figure, three alarm displays (first alarm display 36a, second alarm display 36b, third alarm display 36c) are arranged on the right side of the display unit 5, and two alarm displays (two alarm displays) are arranged on the left side of the display unit 5. The fourth alarm display 36d and the fifth alarm display 36e) are arranged. The alarm displays placed on each of the left and right sides shall be laid out vertically. In addition, the area of each alarm display is a pentagon extending in the horizontal direction. This pentagon has a shape in which a triangular portion is provided at one end of an elongated rectangular portion extending horizontally and rearward. The triangular portion is located on the center side of the display unit 5.

Then, in this embodiment, the alarm target is divided into five groups, and the alarm display displayed for each group is fixed. The first alarm display 36a to the third alarm display 36c on the right side are GPS target display alarm displays that display information about the alarm target specified based on the position information by GPS, that is, the alarm target specified by the GPS alarm function. The fourth alarm display 36d and the fifth alarm display 36e on the left side are alarm targets detected based on the reception of specific radio waves not based on the position information by GPS, that is, the radar wave alarm function, the radio alarm function, and the like. Radar / radio display that displays information about the specified alarm target The alarm display is used. In this way, by separating the alarm target based on the position information by GPS and the alarm target not based on the left and right, it is preferable because it is possible to instantly understand whether or not the alarm target displayed on the alarm display is due to the GPS alarm.

The specific grouping is as follows. The alarm targets based on location information were divided into three groups: the Orbis group, the inspection / control group, and the other POI group. The alarm target belonging to the Orbis group is a vehicle speed measuring device such as a loop coil, an LH system, a new H system, and a radar type Orbis, and is an alarm target having the highest priority such as caution and importance. For example, the alarm target whose GPS target icon shown in FIG. 7 has a red color belongs to this orbis group. This group of Orbis is displayed on the first alarm display 36a. The information displayed as the first alarm display 36a is the alarm name (for example, the term described in "contents of the alarm" in FIG. 7) in the upper row and the distance to the alarm target in the lower row, and the background in the area of the alarm display. The color is red and the information is displayed in white letters.

The warning target belonging to the inspection / control group is, for example, an area where various inspections and control are performed, and is a warning target having a medium priority such as attention and importance. For example, the alarm target whose GPS target icon shown in FIG. 7 has a yellow color belongs to the inspection / control group. This inspection / control group is displayed on the second alarm display 36b. The information displayed as the second alarm display 36b is the alarm name (for example, the term described in "contents of the alarm" in FIG. 7) in the upper row and the distance to the alarm target in the lower row, and the background in the area of the alarm display. The color is yellow and the information is displayed in white letters.

The other alarm targets belonging to the POI group are alarm targets that do not belong to the above two alarm targets, and are alarm targets having the lowest priority such as attention and importance. For example, the alarm target whose GPS target icon shown in FIG. 7 has a yellow color belongs to the inspection / control group. The information displayed as the third alarm display 36c is the alarm name (for example, the term described in "contents of the alarm" in FIG. 7) in the upper row and the distance to the alarm target in the lower row, and the background in the area of the alarm display. The color is blue and the information is displayed in white letters.

The event generation condition for displaying the GPS target display alarm display (first alarm display 36a to third alarm display 36c) is, for example, when the alarm target is within the reference distance (for example, 1000 m). For example, if the event occurrence condition is that the distance from the current position to the alarm target is within a predetermined reference distance, a plurality of such reference distances are set, and an alarm using an alarm display is used when the distance is within a distant reference distance. It is good to do. When the distance is relatively large, the urgency of the alarm is small, so that the information of the plurality of alarm targets can be displayed using different alarm displays and the information of the plurality of different alarm targets can be recognized.

The alarm target group not based on the position information was divided into two groups, a radar group displayed on the fourth alarm display 36d and a radio group displayed on the fifth alarm display 36e. The alarm target belonging to the radar group is detected by the microwave receiver 14. The information displayed as the fourth alarm display 36d has the alarm name (“stealth” in the figure) in the upper row, the reception level in the lower row, and the speaker icon (also referred to as “mute button”) in the tip side, and is within the area of the alarm display. The background color is red and the information is displayed in white characters. When it is detected that the speaker icon is touched, the control unit 18 alternately switches the setting of "mute / unmute" of the alarm output by the speaker. That is, when the control unit 18 detects that the speaker icon is touched while receiving the radar wave (during radar alarm), the control unit 18 mutes (silences) the alarm sound and emits the alarm sound until the radar wave being received disappears. Temporarily stop ringing. When the control unit 18 detects that the speaker icon is touched during mute, the control unit 18 cancels the mute and outputs an alarm sound accompanying the reception of the radar wave.

The alarm target belonging to the radio group is detected by the radio receiver 15. The information to be displayed as the fifth alarm display 36e is only the alarm name (“car location proximity” in the figure), the background color in the area of the alarm display is yellow, and the information is displayed in white characters.

The event generation condition of the radar group and the radio group, which are the groups of alarm targets not based on the above-mentioned position information, is the reception of the target radio wave, and the event ends when the radio wave is not received.

In each of the alarm displays 36a to 36e, information about the alarm target having a high priority in each group is displayed. The alarm target having a high priority is determined, for example, by the priority assigned to each type of alarm target, the distance from the current location to the alarm target, and the like. Therefore, when there is only one alarm target in the same group, the control unit 18 displays the information of the alarm target on the corresponding alarm display. When there are a plurality of alarm targets in the same group, the control unit 18 selects the alarm target having the highest priority determined in advance, and displays the information of the selected alarm target as an alarm display.

Further, the control unit 18 displays the corresponding alarm display on the display unit 5 when there is a corresponding alarm target around the position of the own vehicle for the first alarm display 36a, the second alarm display 36b, and the third alarm display 36c. It fades in from outside the right screen, and when the alarm target disappears, the corresponding alarm display fades out to the outside of the right screen of the display unit 5. Similarly, for the fourth alarm display 36d and the fifth alarm display 36e, when an event of reception of a predetermined radio wave occurs, the control unit 18 fades in the corresponding alarm display from outside the left screen of the display unit 5. When the reception of the predetermined radio wave is stopped, the corresponding alarm display is faded out to the outside of the left screen of the display unit 5. The fade-in / fade-out may be smoothly performed over a predetermined time (for example, about 1 second). By smoothing it, the movement of the alarm display comes into the driver's field of view, and it is easy to understand that some event has occurred or ended.

Further, although FIG. 6B shows an example in which all five alarm displays are displayed, the alarm display is not displayed when there is no alarm target to be displayed belonging to the group. Therefore, the map information and the like in the display area of the alarm display are displayed without being hidden by the alarm display. That is, as shown in FIG. 6A, there are cases where the alarm display is not displayed at all, cases where only one of the alarm displays is displayed, and cases where a plurality of alarm displays are displayed. There is also. Further, for example, even when only one alarm display is displayed, the alarm display appears at a place predetermined by the alarm target group. Therefore, the user can recognize which group the alarm target belongs to by confirming where on the display screen the alarm display is displayed. Therefore, for example, instead of looking at the information displayed on the alarm display each time the alarm display is displayed, when the alarm display of the group that is of concern to the driver is displayed, the alarm display is displayed by gazing at the alarm display. It is preferable because the information can be confirmed.

In addition, the alarm displays arranged one above the other have higher priority as they are located higher, and are regarded as important alarm target groups. From this, for example, when the alarm display is displayed on the upper side of the display unit 5, the user also confirms the specific content displayed on the alarm display because it is an important alarm target, and gives an alarm on the lower side. When the display is displayed, the information can be easily selected so that the information is not confirmed.

Further, each alarm display is arranged line-symmetrically with respect to the vertical center line of the display unit 5. That is, in the three alarm displays arranged on the left side, the central second alarm display 36b is arranged at the center position in the vertical direction, and the first alarm display 36a is equidistant above and below the second alarm display 36b. And the third alarm display 36c are arranged. Further, in the two alarm displays arranged on the right side, the fourth alarm display 36d and the fifth alarm display 36e are arranged at equal distances above and below the center position in the vertical direction. By making it line symmetric, it looks beautiful and has a neat arrangement.

Furthermore, the five alarm displays have a layout in which the positions are alternately shifted in the vertical direction. The apex of the triangular part on the tip side of the pentagonal alarm display faces the gap of the alarm display arranged vertically on the opposite side. By staggering in this way, for example, as shown in FIG. 6 (c), even if the apex on the tip side of the alarm display is extended to the opposite side deeper than the center in the horizontal direction, the alarm on the opposite side is displayed. It does not overlap with the display. Therefore, the area for displaying the information to be alarmed can be widened, and more contents can be displayed and provided to the user.

Further, the background color of each alarm display area is made semi-transparent so that the information (map information and the like in FIG. 6) displayed in the main display area R1 can be visually recognized. In addition, the notification by the alarm sound does not affect the group / group, and outputs the alarm target having the highest priority.

By the way, even in the conventional product, there is a function of notifying the information of the alarm target by character information or the like. The conventional display location is the lower part of the main display area R1, and the information to be notified is an alarm name or the like. However, in the conventional product, only one alarm target is displayed, and the alarm target having the highest priority is selected. Since this conventional product is one that is determined according to the priority provided, for example, if there is a speed measuring device in the vicinity of the highest priority and information about it is displayed, for example, Even if an event based on another alarm target such as radar wave reception occurs, it cannot be known. Furthermore, since one alarm target to be displayed uniformly based on the priority was determined according to predetermined rules such as the type of alarm target and the distance to the alarm target, the situation of the user such as the driver at that time. -Depending on the state, it is not always the alarm target that the user wants to see most or is interested in, and there is a problem that information provision is insufficient. On the other hand, in the present embodiment, up to five alarm targets belonging to different groups can be displayed, so that the driver can obtain necessary alarm target information at his / her convenience.

Further, since all the alarm targets are in the same position such as the lower part of the main display area R1 of the display unit 5, the user must pay close attention to the actually displayed contents to confirm what alarm targets are. Since it is not possible to know whether it is an alarm, it is necessary to check it each time it is displayed. Therefore, the number of times the display unit is viewed increases, and the time for looking in front of the vehicle decreases. Furthermore, it is necessary to see information that is unnecessary or not very important for the driver, which causes wasteful labor and is not easy to use. On the other hand, in the present embodiment, since the position of each alarm display is fixed, it is possible to determine whether or not it is necessary to read the information displayed on the alarm display based on the display position of the alarm display or the like. Therefore, it is possible to select not to see the warning display, which is preferable because the possibility of seeing unnecessary information is reduced and the ratio of looking in front of the vehicle increases.

(Modification example of alarm using alarm display)
In the above-described embodiment, the display of the alarm display is smoothly faded in and faded out, but the present invention is not limited to this, and the displayed portion is divided into several times and moved stepwisely and discretely. It may be enlarged or reduced, or the entire alarm display may be displayed / hidden suddenly. Further, the dimensions and shape of each alarm display are arbitrary, and the background color may be arbitrarily set.

[Embodiment 2 of alarm using display unit 5] (animation alarm)
The animation alarm function is, for example, an animation dedicated to each alarm target when a predetermined event occurs while displaying map information as shown in FIG. 6A by the MAP display function of the standby screen display function. It is a function to display. The animation is 3D and 3D. This animation is stored in a predetermined storage means (hereinafter, referred to as database 19) such as a database 19 in association with the type of alarm target. Further, the alarm sound output in conjunction with the reproduction / display of this animation is stored in the database 19 in association with the type of the display alarm target. Then, in the present embodiment, the map is not slid to open a space for displaying the animation, and the control unit 18 displays the animation on the displayed map. That is, the control unit 18 accesses the database 19 when an event occurs, reads out the corresponding animation data based on the type of the alarm target to be alerted, and displays the read animation at a predetermined position of the display unit 5. The control unit 18 repeatedly plays and displays the animation until the alarm condition of the alarm target disappears, and when the alarm ends, the layer for displaying the map that returns to the original screen and the layer for displaying the animation are different. , Display the animation on the map. Further, the control unit 18 accesses the database 19 when an event occurs, reads out the data of the corresponding alarm sound based on the type of the alarm target to be alarmed, and outputs the read alarm sound.

In this animation alarm, since the display area of the main display area R1 does not shrink or move in a predetermined direction, the display area of the map to be output can be secured while remaining large. Therefore, the map is easy to see. Further, when the map is slid, the own vehicle icon 31 is also slid and displaced. In addition, the time for displaying an animation by this kind of animation alarm function is often relatively short. Then, if the display area of the main display area R1 is changed and the own vehicle icon is also displaced in such a short period of time, it becomes difficult to see, but in the present embodiment, such a situation does not occur and it may be easy to see.

Further, since the animation is superimposed on the map and output and displayed, the entire screen of the display unit 5 can be used as the area for displaying the animation. As a result, the dimensions and shape of the animation can be increased and the movement can be increased, which makes it easy to see, makes it easy to intuitively understand the type of alarm target, and makes it easy to understand.

FIG. 8A shows an example of the screen configuration of the animation alarm. The first character alarm unit 37 is arranged at the lower left of the main display area R1, the second character alarm unit 38 is arranged at the lower right of the main display area R1, and the animation 40 dedicated to the alarm is displayed at an appropriate position of the main display area R1. Take the layout. In FIG. 8A, the display position of the animation 40 is slightly to the right of the center in the vertical direction, but as shown below, the animation 40 is displayed at a different position depending on the animation.

The first character alarm unit 37 is a part that displays related information as character information when notifying an alarm target belonging to a radar group and a radio group grouped in an alarm using the alarm display described above. In the case of the wireless group, only the "alarm name" is displayed, and in the case of the radar group, the "level meter", "alarm name", and "speaker icon" are displayed. FIG. 8A shows an example of receiving radar for convenience.

The second character alarm unit 38 is a part that displays related information as character information when notifying an alarm target based on the position information grouped in the alarm using the alarm display described above. Specifically, the "alarm name" and the "distance to the alarm target" are displayed. However, in the case of the alarm of the Orbis group, the character alarm is not given. FIG. 8A shows an example in which the radar is received, so that the second character alarm unit 38 is blank.

* Animation warning of the Orbis group FIG. 8B shows an example of an animation warning for an alarm target belonging to the Orbis group. The figure shows the case where the alarm target is the “H system”. As shown in the figure, since it is an orbis group, the character alarm using the first character alarm unit 37 and the second character alarm unit 38 is not displayed.

The animation 40 is from an animation (see FIGS. 9 (b-1) to (b-4), etc.) in which a 3D object imitating an alarm target rotates in a sphere, as shown in an enlarged manner in FIG. 8 (c). An animation main body portion 40a, a distance gauge 40b arranged around a sphere of the animation main body portion 40a, and a remaining distance display unit 40c are provided. The control unit 18 displays that the animation main body portion 40a rotates once in a predetermined time (for example, about 2 seconds) as one cycle and continuously rotates. Further, as shown in FIG. 8B, the alarm name (here, “H System”) is also superposed on the animation main body portion 40a, and the distance to the alarm target is displayed on the remaining distance display unit 40c (FIG. 8 (FIG. 8). In b), "860 m") is displayed. If the distance to the alarm target changes as the vehicle travels, the value will change accordingly.

The distance gauge 40b is for counting down the remaining distance to the alarm target from 1000 m. It is composed of 20 rectangular blocks arranged in an arc. One block represents 20 m, and a total of 1000 m (= 50 m × 20 m) is represented. The color of the gauge is blue for the eight blocks from the upper end corresponding to 1000-600 m, yellow for the next six blocks corresponding to 600-300 m, and from the lower end corresponding to 300-0 m. The six blocks in are red. Change the color of the block that has passed the remaining distance to gray. As a result, for example, as shown in FIG. 9 (a-1), when the remaining distance is 800 m, the color of the upper four blocks is changed to gray, and when the remaining distance is 450 m, all the blue blocks are changed to gray. Change, and change the three yellow blocks to gray (Fig. 9 (a-2)). Going further, for example, when the remaining distance is less than 300 m, it becomes a red block and a gray block (Fig. 9 (a-3)), and when the remaining distance becomes 0 m, all the blocks become gray (Fig. 9 (a-4)). ). Further, when the distance to the alarm target is 300 m or less, it is advisable to control the red gauge so as to blink.

In the above-described embodiment, the alarm target is described by taking the H system as an example, but the animation of the alarm target belonging to another Orbis group also only changes the rotating 3D object displayed in the sphere of the animation main body portion 40a. So, it is good to have other configurations in common. An example of the animation main body portion 40a to be alarmed is shown in FIGS. 9 (c-1) to 9 (c-4). 9 (c-1) is a radar, FIG. 9 (c-2) is an LH system, FIG. 9 (c-3) is a loop coil, and FIG. 9 (c-4) is a phototube type.

* Animation warnings of the control group Figures 10 (a) and 10 (b) show examples of animation warnings for "general unspecified" warning targets. Since it is a control group, the control unit 18 outputs information about the alarm target that is the basis for displaying the animation 40, and outputs information about the alarm target to the second character alarm unit 38. In the animation 40, the flag of the stop moves in a fluttering motion (see FIG. 10 (b)). This stop flag imitates the flag used by police officers and others to stop a running vehicle during an actual crackdown. As a result, a sense of presence is generated, the driver's attention is drawn to the fact that the vehicle is in the control area, and safe driving can be promoted. In addition, it is preferable that the flag sways in a fluttering motion, which makes it possible to create the feeling that a police officer is waving the flag during an actual crackdown, and enhances the sense of presence.

Furthermore, the alarm sound was a whistle sound such as "pee-pip". The sound of the whistle should be similar to what a police officer blows during an actual crackdown. By outputting the sound of the whistle along with the reproduction of the animation of the flag swaying, it is possible to reproduce the situation of the crackdown site more realistically, and it is preferable because it is possible to surely inform the driver etc. that the crackdown area is being passed. ..

FIG. 10C shows an example of an animation alarm display screen in which the alarm target is “moving orbis”. In animation 40, a one-box car appears from the right side of the screen (Fig. 11 (a) → (c)), a part of the hatchback at the rear opens, and an infrared flash at the back of the rear window shines (Fig. 11 (d) →). (F)) After that, the hatchback at the rear is closed and the screen moves out of the screen from the left side of the screen. The control unit 18 repeats and reproduces this one cycle in, for example, about 3 seconds. The alarm sound is a shutter sound. For example, the control unit 18 may output sound so that a shutter sound is produced at the timing when the infrared flash shines in the animation.

There are various types of animation warnings for the crackdown group other than the above. For example, FIG. 12A shows an example of an animation warning display screen in which the warning target is “manned speed control”. In the animation 40, the radar antenna portion 41a first appears, and the ripple-shaped radio wave 41b is emitted from the antenna toward the own vehicle. The radio wave 41b expresses the feeling that the radio wave is heading toward the own vehicle as the number of wheels gradually increases.

FIG. 12B shows an example of a display screen of an animation alarm whose alarm target is “tracking type”. In the animation 40, for example, a masked police car appears and repeats the movement away. For example, by displaying the up of the vehicle seen from the back side (for example, only near the license plate), gradually enlarging the displayed part, displaying the entire back of the vehicle, and reducing the entire back, the own vehicle can be displayed. Reproduce the appearance of overtaking. Such an operation is repeatedly reproduced, but preferably, the motion of the undercover police car overtaking is reproduced as it is for a predetermined number of times (for example, once), and after that, the red warning light may be blinked. Further, a police motorcycle may appear on the left half of the screen, a masked police car may appear on the right half, or only a police motorcycle may appear. The alarm sound should be a sound that resembles a siren.

FIG. 12C shows an example of an animation warning display screen in which the warning target is “intersection control”. In the animation 40, for example, a wire frame intersection appears in the center of the screen and rotates in 3D.

* Animation warning of the inspection area group FIGS. 12 (d) to 12 (g) show an example of the animation warning of the inspection area group. First, FIG. 12D shows an example of an animation alarm display screen in which the alarm target is “unspecified”. In the animation 40, for example, the pylon on both sides moves from the front to the back. FIG. 12 (e) shows an example of the display screen of the animation alarm whose alarm target is the “seat belt inspection”. In the animation 40, the seatbelt portion 42a separated from the lock portion 42b extends, and the tip of the seatbelt portion 42a expands and fits the lock portion 42b. As the alarm sound, for example, it is preferable to output a clicking sound according to the movement of the lock portion. FIG. 12 (f) shows an example of an animation alarm display screen in which the alarm target is “inspection of mobile phone while driving”. Animation 40, for example, makes a mobile phone vibrate and tremble. The alarm sound may be, for example, a vibrating sound of a mobile phone. FIG. 12 (g) shows an example of a display screen of an animation alarm whose alarm target is “drinking inspection”. Animation 40 makes a toast, for example, with a jug.

* Animation warnings for other POI groups Fig. 12 (h) and subsequent figures show an example of animation warnings for other POI groups. First, FIG. 12H shows an example of an animation alarm display screen in which the alarm target is “My Area”. In the animation 40, for example, a medal in which the character "My" is embossed on a gold medal moves in a three-dimensional horizontal rotation. Displayed when you are in the area registered in My Area. FIG. 12 (i) shows an example of the display screen of the animation alarm whose alarm target is the “service area”. In the animation 40, for example, a medal in which the character "SA" is embossed rotates three-dimensionally horizontally. FIG. 12J shows an example of an animation alarm display screen in which the alarm target is a “parking area”. In the animation 40, for example, a medal in which the character "PA" is embossed rotates three-dimensionally horizontally. FIG. 12 (k) shows an example of an animation alarm display screen in which the alarm target is a “long tunnel”. Animation 40, for example, makes a movement in which the tunnel gradually becomes longer. Also, for example, from the view of a vehicle entering the tunnel from the entrance of the illustrated tunnel and passing through the tunnel, the view is such that the exit of the tunnel is far away, and then the exit is gradually approached. It is good to make a good movement. FIG. 12 (k) shows an example of an animation alarm display screen in which the alarm target is a “short tunnel”. Animation 40, for example, makes a movement in which a plurality of short tunnels appear. This multiple appearance means, for example, that a short tunnel is passed (for example, the time spent in the tunnel is shorter than that of a long tunnel, and the exit that can be seen when passing through the tunnel is also close. It is preferable to repeatedly reproduce the movement (shown) a plurality of times, more preferably three times or more. Alternatively, a plurality of tunnels may be simply displayed at the same time.

FIG. 13A shows an example of an animation warning display screen in which the warning target is “Roadside Station”. Animation 40, for example, makes a spinning motion of a roadside station sign. FIG. 13B shows an example of an animation alarm display screen in which the alarm target is “Torupa (viewpoint parking)”. The animation 40, for example, makes a spinning motion of the torpa sign. FIG. 13C shows an example of a display screen of an animation alarm whose alarm target is “highway oasis”. The animation 40, for example, makes the Ferris wheel rotate. FIGS. 13 (d) and 13 (e) show an example of an animation warning display screen in which the warning targets are "highway sharp curve" and "highway continuous curve", respectively. In the animation 40, for example, the road gradually curves and extends from the lower side of the screen together with the characters of CAUTION. FIG. 13 (f) shows an example of an animation warning display screen in which the warning target is a “police station”. In the animation 40, for example, the Order of the Rising Sun rotates. FIG. 13 (g) shows an example of an animation warning display screen in which the warning target is the “traffic police corps”. The animation 40, for example, makes a zoom-in motion while blinking the characters "high-speed traffic police force". FIG. 13 (h) shows an example of the display screen of the animation alarm whose alarm target is “N system”. The animation 40 displays, for example, an image in which the cameras of the N system are lined up, and gradually approaches (enlarges) the motion. At this time, the lens of the camera also shines brilliantly. Further, although specific illustration is omitted, for example, even when the alarm target is the "traffic monitoring system", the animation 40 is the same, and the "alarm name" displayed on the second character alarm unit 38 is different. For example, in the case of the N system, it is set to "NSsystem" as shown in the figure, and in the case of the "traffic monitoring system", it is set to "NKSystem". FIG. 13 (i) shows an example of an animation warning display screen in which the warning target is an “intersection monitoring point”. Animation 40, for example, blinks the characters "intersection monitoring point". Also, at this time, it is advisable to perform the movement of zooming in.

FIG. 13 (j) shows an example of an animation warning display screen in which the warning target is the “accident-prone area”. The animation 40 makes, for example, a movement in which a car collides with a car. Also, as a sound effect, it is advisable to apply a sudden brake such as "Keigashan" and then output the sound of the cars colliding with each other.

FIG. 13 (k) shows an example of the display screen of the animation alarm whose alarm target is the “signal ignore suppression system”. The animation 40 blinks, for example, the character "red light camera". Also, at this time, it is advisable to perform the movement of zooming in.

FIGS. 13 (l) and 13 (m) show an example of an animation warning display screen in which the warning targets are the "expressway branch point" and the "expressway junction point", respectively. In the animation 40, for example, the road gradually extends from the lower side of the screen together with the characters of CAUTION.

FIG. 13 (n) shows an example of a display screen of an animation alarm whose alarm target is “highway radio”. The animation 40 displays, for example, a radio tuner 43a in the upper row and a digital frequency display 43b in the lower row. The tuner 43a moves so that the arc increases one by one from the left side, and the frequency digital display 43b counts up from 1200 kHz and stops at 1680 kHz.

FIG. 13 (o) shows an example of the display screen of the animation alarm whose alarm target is “prefectural border”. Animation 40, for example, makes a spinning motion of a prefectural border sign.
FIG. 13 (p) shows an example of an animation alarm display screen in which the alarm target is the “ETC lane”. The animation 40 displays, for example, the character 44a of "ETC" in the upper row, and inserts the ETC card 44c into the ETC on-board unit 44b in the lower row.

FIGS. 13 (q) and 13 (r) show an example of an animation warning display screen in which the warning target is "pause control" and "parking prohibited priority area". In the animation 40, for example, the "stop sign" and the "parking prohibition sign" blink, respectively. FIGS. 13 (s) and 13 (t) show an example of an animation warning display screen in which the warning target is a "parking lot" or a "parking prohibited heavy point area". The animation 40, for example, rotates when a parking lot mark or a parking prohibition sign is rotated.

FIG. 14A shows an example of an animation warning display screen in which the warning target is the “on-vehicle aiming frequent occurrence area”. The animation 40 performs, for example, a movement of swinging down a hammer. Also, as a sound effect, it is advisable to output a sound such as "Gashan" that the glass breaks at the timing when the hammer is swung down.

* Radar group animation warning FIGS. 14 (b) to 14 (s) show an example of a radar group animation warning. First, FIG. 14B shows an example of an animation warning display screen in which the warning target is a “radar wave”. In the animation 40, for example, ripples are generated from the upper part of the screen, and the waves rush toward the own vehicle (the arcs increase by one). FIG. 14C shows an example of an animation alarm display screen in which the alarm target is a “stealth wave”. The animation 40, for example, makes a movement in which an annular wave rushes from the upper part of the screen. FIG. 14D shows an example of an animation alarm display screen in which the alarm target is “cancel”. The animation 40, for example, makes a movement in which the characters of CANCEL gradually become larger. Further, since the alarm targets belonging to the radar group shown in FIGS. 14 (b) to 14 (d) have high priority such as urgency and importance, the color of the animation is red.

* Radio group animation warning FIGS. 14 (e) to 14 (r) show an example of a radio group animation warning. First, FIG. 14 (e) shows an example of an animation alarm display screen in which the alarm target is "car location proximity". Animation 40, for example, makes a large police car move through from right to left. FIG. 14 (f) shows an example of an animation alarm display screen in which the alarm target is “far away from the car location”. Animation 40, for example, makes a small police car move through from right to left. In addition, although specific illustration is omitted, when the alarm target is within the "car location area", the animation should not be displayed in particular, the backlight should be blinked, and "PCin" should be displayed as the alarm name in the first character alarm unit. ..

FIG. 14 (g) shows an example of an animation warning display screen in which the warning target is “parallel running tracking”. Animation 40, for example, performs a movement in which a police car appears from the front to the back of the screen. This movement is, for example, by displaying the up of the vehicle as seen from the rear side (for example, only near the license plate), gradually enlarging the displayed part, displaying the entire rear surface of the vehicle, and reducing the entire rear surface. , Reproduce the appearance of overtaking the own vehicle.

FIG. 14H shows an example of an animation alarm display screen in which the alarm target is “passing”. The animation 40, for example, makes a movement of a police car passing from the back of the screen to the front. This movement, for example, gradually enlarges the picture of the entire vehicle as seen from the front side and finally displays the up of the vehicle as seen from the front side (eg, only the central portion of the front grille).

FIG. 14 (i) shows an example of the display screen of the animation alarm whose alarm target is “Caution for crackdown”. In the animation 40, for example, the flag of the stop moves in a fluttering motion. The control unit 18 displays "Police Sign" as an alarm name on the first character alarm unit 37.

FIG. 14 (j) shows an example of an animation alarm display screen in which the alarm target is “inspection caution”. In the animation 40, for example, the pylon on both sides moves from the front to the back.

FIG. 14 (k) shows an example of a display screen of an animation alarm whose alarm target is “control radio”. The animation 40 is, for example, the same as in FIG. 14 (i). The control unit 18 displays "Police" as an alarm name on the first character alarm unit 37.

FIG. 14 (l) shows an example of a display screen of an animation alarm whose alarm target is “digital radio”. The animation 40, for example, performs a movement in which a radio wave 45b is emitted from the radio 45a. The radio wave 41b is an animation in which the number of wheels gradually increases. The control unit 18 displays "CarDigital" as an alarm name on the first character alarm unit 37. Further, although specific illustration is omitted, for example, the alarm target is "police activity radio" or "jurisdiction radio" using the same animation, and the alarm name displayed on the first character alarm unit 37 is "PoliceRadio" or "Policeman". It corresponds by.

FIG. 14 (m) shows an example of an animation alarm display screen in which the alarm target is “Heri-Tele Radio”. Animation 40, for example, makes a helicopter (Apache) pass from right to left. FIG. 14 (n) shows an example of a display screen of an animation alarm whose alarm target is “digital radio”. The animation 40 is, for example, the same as in FIG. 14 (l). The control unit 18 displays "LoPwrPolice" as an alarm name on the first character alarm unit 37. FIG. 14 (o) shows an example of an animation alarm display screen in which the alarm target is a “police phone”. Animation 40, for example, makes a movement of opening a mobile phone. Since the alarm targets shown in FIGS. 14 (e) to 14 (o) have lower priorities such as urgency and importance than those of the radar group, the color of the animation is yellow.

FIG. 14 (p) shows an example of a display screen of an animation alarm whose alarm target is “firefighting radio”. For example, the animation 40 performs a movement in which a radio wave is emitted from the radio as in FIG. 14 (l). However, since the urgency and importance of this alarm target is even lower than that of the above digital radio, the color of the animation is blue. FIG. 14 (q) shows an example of an animation alarm display screen in which the alarm target is "firefighting heli-tele radio". Animation 40, for example, makes a helicopter (Apache) pass from right to left. 14 (r) and 14 (s) show an example of an animation alarm display screen in which the alarm targets are "wrecker radio" and "emergency radio", respectively. In the animation 40, for example, a "tow truck" and an "ambulance" move by each other. For the same reason as the "firefighting radio" shown in FIG. 14 (p), the colors of the animations after FIG. 14 (q) are also blue.

[Embodiment 3 of alarm using display unit 5] (live-action alarm)
In the animation alarm function, for example, when a predetermined event occurs while displaying map information as shown in FIG. 6A by the MAP display function of the standby screen display function, the corresponding alarm target is registered. It is a function to display a live-action image of a point. For example, for each registration point of the orbis (loop coil / LH system / H system / radar type orbis) whose alarm target is an orbis (loop coil / LH system / H system / radar type orbis), a photograph of the actual site is taken and registered in a database 19 or the like. For example, when the current position is about 500 m before Orbis, the control unit 18 accesses the database 19, calls the corresponding actual Orbis photograph (live-action), and displays it on the display unit 5.

Further, in the present embodiment, the map is not slid to open a space for displaying the live-action image, and the control unit 18 displays the live-action image on the displayed map. Therefore, as with the animation warning, even if this live-action image is displayed, the display area of the map is not narrowed and difficult to see, and the position of the own vehicle icon or the like on the map is displaced in the display unit by sliding the map. By doing so, it does not become difficult to confirm the position of the own vehicle or the alarm target on the map. Therefore, the map may be easy to see. Further, by enlarging the display area of the live-action image, the alarm target displayed in the live-action image can be intuitively understood. Further, it is preferable to indicate the position of the orbis to be alarmed by using, for example, an instruction mark such as an arrow.

FIG. 15 shows an example of a live-action alarm display screen using a live-action image. The live-action image 50 is displayed on the map displayed in the main display area R1 by changing the layer. By making the live-action image 50 almost the entire display screen of the display unit 5, the live-action image of the alarm target can be displayed in a large size, which makes it easier to see. Furthermore, the alarm target was imaged together with the background, and the alarm target was set to be the center of the screen. As a result, the alarm target is output to the center of the screen of the display unit 5, so that it may be conspicuous.

The first character alarm unit 37 is arranged at the lower left of the main display area R1, the second character alarm unit 38 is arranged at the lower right of the main display area R1, and the animation 40 dedicated to the alarm is displayed at an appropriate position of the main display area R1. Take the layout. In FIG. 15, the display position of the animation 40 is slightly to the right of the center in the vertical direction, but as shown below, the animation 40 is displayed at a different position depending on the animation.

The first character alarm unit 37 is a part that displays related information as character information when notifying an alarm target belonging to a radar group and a radio group grouped in an alarm using the alarm display described above. In the case of the wireless group, only the "alarm name" is displayed, and in the case of the radar group, the "level meter", "alarm name", and "speaker icon" are displayed. FIG. 15 shows an example of receiving radar for convenience.

The second character alarm unit 38 is a part that displays related information as character information when notifying an alarm target based on the position information grouped in the alarm using the alarm display described above. Specifically, the "alarm name" and the "distance to the alarm target" are displayed. However, in the case of the alarm of the Orbis group, the character alarm is not given. FIG. 8A shows an example in which the radar is received, so that the second character alarm unit 38 is blank.

Further, the dimensions of the live-action image 50 are such that the vertical direction is the length over almost the entire display unit 5, and the horizontal direction is shorter than the total length of the display unit 5. As a result, a part of the side edge side of the map is exposed on the lateral side of the live-action image 50. Then, the control unit 18 blinks the live-action image 50 in a predetermined time (for example, 2 seconds). For blinking, changing the transmittance of a photograph or panel as 10 → 20 ... 100 → 90 ... 10% is displayed as one cycle. As a result, for example, from the state in which the map looks clear as shown in FIG. 15 (a), the live-action image 50 appears on the map as shown in FIG. 15 (b), and then in FIG. 15 (c). As shown, the live-action image 50 appears firmly and the map is hidden and invisible, and after the state where both the map of FIG. 15 (b) and the live-action image can be seen again, the map shown in FIG. 15 (a) is displayed. One cycle is the transition to a state in which the image can be clearly seen.

By blinking in this way, the live-action image 50 appears on the screen and disappears again, so that the display is repeated, which has an impact and can surely inform the user of its existence. In addition, by blinking, the state where the live-action image can be seen on the entire display screen (Fig. 15c) and the state where the map can be clearly seen (Fig. 15 (a)) appear alternately, so it is good to be able to check the contents of the map. ..

Further, by making the dimensions of the live-action image 50 shorter than the map as described above, even if the map is hidden by the live-action image 50 and cannot be seen as shown in FIG. 15 (c), the map is outside the right end of the live-action image. I can see a part of. Therefore, it can be seen that the map exists.

[Embodiment 4 of alarm using display unit 5] (Special (SP) alarm)
In each of the above-described embodiments, the types of alarm targets, the alarms to be notified for each alarm (alarm display, animation), and the contents of the alarm (live image) prepared for each alarm target are different, but the SP of the present embodiment is different. The content of the alarm is changed based on the information other than the type of the alarm target. As the information other than the type of the alarm target, the information related to the time such as the season, the date and time, etc. was used. Specifically, different animations are displayed for each of the four seasons of spring, summer, autumn, and winter. In addition, it may be different during the day, such as day and night. Furthermore, this special alarm is an alarm dedicated to a predetermined standby screen. The predetermined standby screen is, for example, a clock / calendar standby screen.

FIG. 16A shows an example of the screen configuration of the clock / calendar standby screen. As shown in the figure, as in the other embodiment, the icon display unit 32b, the vehicle speed display unit 32c, and the compass display unit 32d are arranged at the upper predetermined positions of the display area of the display unit 5 to display the display area. A layout is adopted in which the first character alarm unit 37 is arranged at the lower left and the second character alarm unit 38 is arranged at the lower right of the display area. The display units 32b to 32d and the alarm units 37 and 38 are the same as those of the above-described embodiments.

In the present embodiment, the clock unit 51 is arranged on the left side of the display area, and the calendar unit 52 is arranged on the right side of the display area. The control unit 18 displays the current time acquired from the internal clock or the GPS receiver 13 on the clock unit 51 as a diagram imitating an analog clock. This figure is an animation in which the second hand, short hand, and long hand change from moment to moment with the passage of time. Further, the control unit 18 outputs today's date and day of the week as character information to the calendar unit 52.

Further, the control unit 18 outputs a different background screen depending on the season and time in the display area of the display unit 5. FIG. 16A shows a background screen for summer. The background screen, the information display unit, the character alarm units 37 and 38, the clock unit 51, and the calendar unit 52 each play and output using different layers. As a result, it is possible to individually control the display / non-display of any object.

The background screen for this summer expresses the scenery in the sea. When an event for outputting a predetermined alarm occurs while the background screen for summer is displayed, the control unit 18 reproduces and outputs a predetermined alarm animation. The alarm animation is strongly related to the background screen and the season, and when the background screen as shown in FIG. 16 (a) is in the sea, the bubbles generated in the sea as shown in FIG. 16 (c). However, it was supposed to move upward. Since this alarm animation is commonly used for different types of alarm targets, it is possible to recognize that there was some alarm target by playing the alarm animation, but the specific type of alarm target is specified. Can not. The type of the alarm target is specified by the character information output to the first character alarm unit 37 and the second character alarm unit 38.

Specifically, the background screens and alarm animations that differ depending on the season are shown in FIGS. 16 (b) to 16 (e). FIG. 16B shows a version in which the season is spring (March to May) and the time is daytime, and a background screen in which a cherry tree (particularly a flower part) is drawn on a blue background imagining a blue sky. And the animation for warning is a snowstorm with cherry blossom petals scattered. The layer for displaying the alarm animation is higher than the layer for displaying the information display unit, the character alarm units 37 and 38, the clock unit 51, and the calendar unit 52, respectively. As a result, as shown in FIG. 16B, petals are drawn on the picture of the clock of the clock unit 51 and the characters of the calendar unit 52, and the picture of the clock is hidden by the petals. By doing so, the alarm animation will not be hidden by other display elements such as the clock, and it will be possible to enjoy and heal the user such as the driver, and the event is occurring. It can also be surely notified that it is.

Although specific illustration is omitted, in the version where the time is night, the background screen is black to express midnight (see FIG. 16 (d)), and when an event occurs, the control unit 18 sets the background of the black background pattern. Play and output the alarm animation Sakura Fubuki on the screen.

FIG. 16C shows a version in which the season is summer (June to August) and the time is daytime, and the background screen is an image of the sea. This background image may be fixed as a single still image, or may be, for example, a moving image that reproduces the fluctuation of light shining into the sea. Then, the alarm animation is a movement in which bubbles rise (move from the bottom to the top of the screen). By expressing the blue sea on the background screen, it is possible to give the user a feeling of exhilaration and evoke a refreshing feeling, so that the user can enjoy it.

Although specific illustration is omitted, in the version where the time is night, the background screen is black to express midnight (see FIG. 16 (d)), and when an event occurs, the control unit 18 sets the background of the black background pattern. Play and output fireworks for alarm animation on the screen. If this fireworks is a fireworks display, which is also a summer tradition, it will bring out a summery feeling, and it can be expected to have a relaxing effect on the user's mind, so it is good for the user to enjoy it.

FIG. 16D shows a version in which the season is autumn (September to November) and the time is night, and the background screen is black to express midnight. The alarm animation is a movement in which the petals of autumn leaves are scattered (moving from the upper side to the lower side of the screen). Also, in the version where the time is daytime, it is preferable to use a background screen in which autumnal trees (especially the flower part) are drawn on a blue background that imagines a blue sky, as in the case where the season is spring.

In FIG. 16 (e), the season is winter (December to February) and the time is the night version, and the background screen is black to express midnight. The alarm animation is a movement of snow (for example, moving from the upper side to the lower side of the screen). Also, in the version where the time is daytime, it is preferable to use a background screen in which a blue background pattern that images the blue sky is drawn, as in the case where the season is spring.

Further, in the present embodiment, three types of alarm animations are prepared according to the type of alarm target and the like, according to the urgency / priority of small / medium / large. Further, it is preferable to output a predetermined alarm sound together with the reproduction of the alarm animation. These alarm animations and alarm sounds are registered in the database 19 in association with each other, and the control unit 18 accesses the database 19 when an event occurs, reads out the corresponding alarm animations and alarm sounds, and outputs them at a predetermined timing. do.

・ When the season is spring, both day and night, "the number of petals of cherry blossom blizzard is small and flickering (low priority)" → "the number of petals of cherry blossom blizzard is medium, and it is large with strong wind. Change from "Scattering feeling (medium priority)" to "Feeling that the number of petals of Sakurabuki is large and large and small petals are scattered all over the screen (high priority)".
・ If the season is summer (daytime), "small bubbles and a lumpy feeling (low priority)" → "a mixture of small and medium bubbles and a lumpy feeling (medium priority)" → "bubbles" Is a mixture of small, medium, and large, and it feels lumpy and rugged (high priority). "
・ If the season is summer (night), "Small fireworks are single-shot animations, a warning sound of" Huepan "(low priority)" → "Medium fireworks are a series of animations," Hugh x 5 Panpan x 5 "sound effect (medium priority)" → "Big fireworks (full screen Oyanagi) animation, change to" Hudow ~~~ n "sound effect (high priority)".
・ When the season is autumn, both day and night, "the number of autumn leaves is small and the feeling of flickering (low priority)" → "the number of autumn leaves is medium and the feeling of being scattered (medium priority)" → Change to "the number of autumn leaves is large, and the petals of large and small sizes are scattered all over the screen (high priority)".
・ When the season is winter, both day and night, "the number of snow is small and the feeling is flickering (low priority)" → "the number of snow is medium and the feeling is stubborn (the movement is the same as small)""→"It's a snowstorm animation, and it feels like it's a little bit (high priority) ". For certain seasons, it is advisable to fade out the background screen (the background disappears). The predetermined season may be, for example, summer (night), autumn, and winter.

The alarm by this alarm animation may be performed alone or in combination with other alarms. For example, when an event occurs such as when the distance to the alarm target registered in the database 19 reaches the reference distance or when a predetermined radio is received, the alarm animation is played back and output for one cycle (about 2 to 3 seconds). Then, the voice is output according to the type of the alarm target. The alarm using the first character alarm unit 37 or the second character alarm unit 38 may be performed after, for example, playing the alarm animation, or at the same time.

In addition, in the case of a normal alarm target type, an alarm is first given by an animation for warning, but for example, in the case of a radar group or a radio group, there is an urgency, so a voice notification such as "It is a radar" is given first. After that, one cycle of notification by the alarm animation is performed, and then an alarm such as a voice corresponding to the type of the alarm target is performed until the event is canceled.

[Embodiment 5 of alarm using display unit 5] (∞ alarm)
The ∞ alarm is a special alarm by interlocking the optical tube and the display unit 5. The special alarm linked with this optical tube works together with the map screen. Whether or not to issue a special alarm is determined by setting the mode. In the case of setting to perform a special alarm, if the standby screen of the display unit 5 is other than the map screen (Map screen), the screen is switched to the map screen, a predetermined special alarm is issued, and the screen returns to the original screen when the alarm is completed. The order of priority is 1. Orbis group, 2. Radar group, 3. Inspection control group, 4. Radio group, 5. Other POI group.

Since the alarm by interlocking the optical tube 20 and the display unit 5 is a special alarm, the control unit 18 fuses the display unit 5 and the optical tube 20 when a plurality of predetermined alarm conditions are satisfied. It is advisable to issue an alarm. The predetermined plurality of warning conditions include warning conditions based on position information such that the relative positional relationship between the position of the warning target stored as map information in the database 19 and the current position information of the vehicle becomes a predetermined setting condition, and the speed. There are some that satisfy different types of alarm conditions, such as alarm conditions based on predetermined radio wave reception, such as receiving microwaves in a frequency band emitted from a measuring device by a microwave receiver 14. As a specific example of satisfying this different type of alarm condition, for example, when the alarm target is a speed measuring device and the alarm condition based on the position information is satisfied, the microwave of the frequency band emitted from the speed measuring device is used. In some cases, the alarm conditions based on the reception of radio waves are satisfied at the same time.

Further, when a plurality of alarm conditions are satisfied, a plurality of alarm conditions of the same type may be satisfied at different times. For example, the warning condition is the warning condition based on the position information as described above, and the relative positional relationship with the same warning target is the first distance (for example, 2000 m), the second distance shorter than the first distance (for example, 1000 m), and the second. Assuming that the warning conditions based on the position information are satisfied when the distance is shorter than the distance (for example, 500 m), the order determined by the traveling of the vehicle, for example, the first distance → the second distance → the third The distance may be met in order.

Further, it is further preferable to provide both a case where a plurality of types of the above alarm conditions are satisfied and a case where a plurality of the same type of alarm conditions are satisfied at different times. For example, it is assumed that a plurality of specific alarm conditions are satisfied when microwaves having a predetermined frequency are received and the first distance → the second distance → the third distance are satisfied in this order.

By issuing a fused alarm when a plurality of specific alarm conditions are satisfied, the chance of generating the fused alarm is reduced. Therefore, when the fused alarm is generated, the surprise property is high and the impact on the driver is large, so that the alarm can be notified to the driver more reliably.

Further, the above-mentioned microwave reception condition may be such that the microwave is received at each position when the position conditions of the first distance, the second distance, and the third distance are satisfied. By doing so, it is good that a plurality of specific alarm conditions are less likely to be satisfied and the chance of occurrence is smaller. When the above-mentioned plurality of alarm conditions are not satisfied, it is preferable not to issue an alarm in which the display unit 5 and the optical tube 20 are fused. For example, if a plurality of predetermined alarm conditions are not satisfied, but other alarm conditions are satisfied, an alarm is given by either the display unit 5 or the optical tube 20, and the alarm is displayed when the predetermined plurality of alarm conditions are satisfied. It is preferable to issue an alarm in which the unit 5 and the optical tube 20 are fused. As a result, the alarm in which the display unit 5 and the optical tube 20 are fused is positioned as a special alarm.

When a plurality of predetermined warning conditions are not satisfied, for example, a warning target suddenly appears in front of the vehicle in the traveling direction due to a change in the course of the vehicle, and the approach is started from a state where the relative distance is shorter than 2000 m. When the conditions of the second distance → the third distance are satisfied in order or the third distance is satisfied without satisfying the conditions of the first distance, it is assumed that the microwave is received when the conditions of each distance are satisfied. Will not meet a plurality of predetermined alarm conditions. Further, even if the position conditions of the first distance, the second distance, and the third distance are satisfied in order, the predetermined plurality of alarm conditions are not satisfied even if the microwave is not received. In these cases, the display unit 5 and the optical tube 20 do not give a fused alarm, and for example, when the conditions for each distance are satisfied, a notification for outputting a message for notifying the passage of the distance is output to the display unit 5. conduct.

* Specific examples of special alarms ** Orbis group (using location information) **
FIG. 17 shows an example of a screen transition of a special alarm that is output when the distance to the alarm target (Orbis) is the first reference distance (long distance: for example, about 2000 m before) while traveling on a highway. .. While driving on a highway, "1. Drive above the speed limit", "2. The distance between the vehicle and the target is 2100 m or less", "3. The direction of the vehicle as seen from the warning target (Orbis) is a predetermined angle ( For example, when all the conditions of "within ± 40 degrees" and "4. the target direction seen from the traveling direction of the own vehicle is within a predetermined angle (for example, ± 20 degrees)" are satisfied, the special alarm shown in FIG. 17 is notified. In the database 19, the monitoring direction is registered for each alarm target (Orbis). The control unit 18 sets a predetermined angle range with reference to the monitoring direction, and determines whether or not the condition 3 is satisfied.

When all four conditions are satisfied, the control unit 18 first outputs a wave animation from the center of the screen, like the Ten Commandments of Moses, in which the screen is broken by waves, as shown in FIG. 17 (a). The central space between the left and right waves is outlined, and the left and right navigation systems move outward. At this time, the sound effect is the sound of a waterfall. This sound effect continues until the end of the animation. At the same time as the start of the animation in which the screen is cracked by this wave, the control unit 18 blinks the full-color LED in red three times. As a result, the optical tubes 20 on both sides of the display unit 5 blink red three times.

Next, as shown in FIG. 17B, the alarm name (also referred to as “target name”) is displayed on the portion split by the wave. In the figure, "H system" is displayed, but one of radar type, H system, LH system, loop coil, and phototube type is displayed depending on the type of alarm target. In addition, the period during which this alarm name is displayed is, for example, while the central part is open to some extent due to the left and right waves. And. Then, when the left and right waves are fully opened, they gradually approach each other to narrow the space, and when the waves close as shown in FIG. 17 (c), the animation of these waves ends. The animation of this wave is, for example, about 3 seconds.

After the end of this wave animation, a live-action alarm for each alarm target is displayed (FIG. 17 (d)). As described with reference to FIG. 15, the live-action alarm gives a notification that the transparency of the live-action image is changed to blink. Therefore, when the blinking is performed a predetermined number of times (for example, 5 times), this live-action alarm is terminated. Further, the control unit 18 outputs a voice of a 2000 m alarm. This voice output informs the direction and distance of the warning target, the road distinction, and the type of the warning target. When the live-action image is blinked five times, the map is displayed as shown in FIG. 15 (e). That is, at the time of the live-action alarm, the alarm name and the remaining distance to the alarm target are output to the second character alarm unit 38. Therefore, even after the end of the live-action alarm, the lower character alarm using the second character alarm unit 38 is continued until the 1100 m alarm is issued.

The alarm of the Orbis group is notified with the highest priority. At this time, if there is an alarm target belonging to the radar group or the radio group, the radar and the radio alarm are simultaneously displayed in the alarm character using the first character alarm unit 37. It is good to do.

FIG. 18A shows a special warning output when the distance to the warning target (Orbis) is the second reference distance (distance shorter than the first reference distance: for example, about 1000 m before) while traveling on a highway. An example of the screen is shown. While driving on a highway, "1. The distance between the vehicle and the target is 1100 m or less", "2. The direction of the vehicle as seen from the warning target (Orbis) is within a predetermined angle (for example, ± 40 degrees)", "3. When all the conditions of "the target direction as seen from the traveling direction of the own vehicle is within a predetermined angle (for example, ± 90 degrees)" are satisfied, the control unit 18 notifies the special alarm shown in FIG. 18A. That is, the lower character alarm using the second character alarm unit 38 is terminated, and the process shifts to the orbis animation (animation alarm of the second embodiment) corresponding to each type of alarm target. At the same time, the control unit 18 controls the light emission of the full-color LED 22, and the optical tubes 20 on both sides blink red five times. This display continues up to 600m. In addition, sound effects and voice output set for each alarm target are also performed.

FIGS. 18 (b) and 18 (c) are output when the distance to the warning target (Orbis) is the third reference distance (distance shorter than the second reference distance: for example, about 600 m before) while traveling on a highway. An example of the screen transition of the special alarm of the normal version is shown. While driving on a highway, "1. The distance between the vehicle and the target is 600 m or less", "2. The direction of the vehicle as seen from the alarm target (Orbis) is within a predetermined angle (for example, ± 40 degrees)", "3. When all the conditions of "the target direction seen from the traveling direction of the own vehicle is within a predetermined angle (for example, ± 90 degrees)" are satisfied, the display shifts to the display of the Orbis 600m dedicated animation. That is, the control unit 18 first displays the alarm screen shown in FIG. 18B.

The concept of this warning screen is to see the warning target (Orbis) from the cockpit's point of view. This alarm screen displays an animation object 61 imitating an alarm target in the center. The animation object 61 animates an approaching Orbis that can be seen in the distance. A distance gauge 62 between targets is arranged at the upper left of the animation object 61. The inter-target distance gauge 62 is like an arc-shaped level meter, and as the distance to the alarm target becomes shorter, the meter portion of a predetermined color (for example, orange) becomes shorter. The inter-target distance display unit 63 is arranged at the upper left of the screen, and the current speed display unit 64 is arranged at the upper right of the screen. Both are digital values, and these values change linearly as the vehicle travels. On the right side of the screen, a speed limit display unit 65, a deviation speed display unit 66, and a radar level meter 67 are arranged under the current speed display unit 64. The current speed is obtained from the transition and elapsed time of the position information acquired from the GPS receiver 13. The speed limit display unit 65 may display, for example, the speed limit at the current position, but preferably the speed limit at the installation position of the alarm target (Orbis). The deviation speed display unit 66 obtains the difference between the current speed and the speed limit (for example, the speed limit of the installation position of the alarm target), and displays the speed difference numerically. At this time, if the speed limit is exceeded, the characters are red, and if the speed limit is not exceeded, the characters are blue. Specifically, the control unit 18 outputs the Delta value obtained below to the deviation speed display unit 66 in the color characters specified by the following rule.
(Current speed)-(Speed limit) = Delta
Delta ≤ 0km / h: Blue characters Delta> 0km / h: Red characters

The radar level meter 67 displays the reception intensity of the received radar wave on a five-point scale. Further, a sub-display 68 is arranged at the lower left of the screen. This sub-display shows the relative position of the vehicle position (red arrow) and the alarm target (red circle). The animation object 61 and the sub-display 68 display 10 levels with respect to the distance. Along with this screen display, the control unit 18 controls the light emission of the full-color LED 22, and starts blinking the light tubes on both sides. This blinking is performed until the alarm has passed and the alarm has ended. Further, the control unit issues an alarm by voice output at a predetermined distance (for example, at 600 m and 300 m).

Then, when the alarm target is passed and the radar wave is no longer received, the control unit 18 returns the display of the display unit 5 to the original screen as shown in FIG. 18 (c), and passes such as "passed". Output the phrase by voice and end the special alarm.

FIG. 19 shows a special version of the special warning that is output when the distance to the warning target (Orbis) is the third reference distance (distance shorter than the second reference distance: for example, about 600 m before) while driving on a highway. An example of screen transition is shown. While driving on a highway, "1. The distance between the vehicle and the target is 600 m or less", "2. The direction of the vehicle as seen from the alarm target (Orbis) is within a predetermined angle (for example, ± 40 degrees)", "3. In addition to "the target direction seen from the direction of travel of the vehicle is within a predetermined angle (for example, ± 90 degrees)", "4. Pass the first reference distance and the second reference distance in order", "between 2000 and 600 m". When all the conditions of "receive radar wave at least once" are satisfied, the display shifts to the Orbis 600m special animation display.

That is, the control unit 18 first displays the alarm screen shown in FIG. 19A. This alarm screen shows a state in which noise is generated in the entire map screen. Further, at this time, the control unit 18 outputs a noise-like sound, for example, an alarm sound of "roughness". Next, after outputting the sound effect that the CRT television disappears, the backlight is turned off in all black as shown in FIG. 19B. Next, the control unit 18 outputs a predetermined dedicated sound effect, controls the full-color LED 22 to emit light at 100% red, causes the optical tube 20 to emit light in red, and displays the screen shown in FIG. 19 (c). For example, the character of ∞ is expressed by the cooperation of the optical tube 20 and the display unit 5 described with reference to FIG. Since the red color represents the image of burning flames, the control unit 18 outputs a sound effect of burning flames at the same time.

After that, the animation for exclusive use of Orbis 600m shown in FIG. 19D is displayed. This Orbis 600m dedicated animation is the same as that of the above-mentioned normal version. In addition, the optical tube is turned off with the display of this Orbis 600m dedicated animation. By displaying FIGS. 19 (a) to 19 (c) prior to displaying the Orbis 600m dedicated animation in this way, it is possible to make the user imagine and expect something special to happen, which is exciting. It can be demonstrated and entertained by the user.

Up to the latest of the alarm target (Orbis), the animation dedicated to Orbis 600m is displayed as in the normal version. Then, at the passing point of the alarm target, the control unit 18 cuts in three images, FIG. 19 (e) → FIG. 19 (f) → FIG. 19 (g). Further, when cutting in these three pictures, the control unit 18 outputs the sound effect of releasing the shutter together with the sound effect of the shutter. This cut-in is displayed one by one in a short time (for example, every 0.3 seconds). By cutting in three pictures in this way, it is good because it has an impact and looks cool. For example, "1. The distance between the own vehicle and the target is 100 m or less", "2. The direction of the own vehicle as seen from the warning target is within a predetermined angle (± 40 degrees))", "3. It is preferable that all the conditions of "the direction of the alarm target viewed from the traveling direction is within a predetermined angle (± 90 degrees)" are satisfied. If the judgment of passage before the cut-in is set to the installation position (0 m point) of the alarm target, the cut-in is performed after passing the actual alarm target, and there is a risk that there will be a gap, but before a predetermined distance. By setting it (for example, within 100 m), there is a sense of presence and the cut-in can be performed at an appropriate timing. Further, even if the GPS accuracy error or the like causes a deviation from the actual position, by cutting in within a predetermined distance, it is possible to suppress the occurrence of a situation in which the cut-in is made after actually passing the alarm target.

Then, the control unit 18 determines the situation at the time of passing, and displays the determination result screen according to any one of FIGS. 19 (h) to 19 (l) according to the determination result. The situation was the speed difference between the running speed and the speed limit. Further, "at the time of passing" was set immediately before passing (for example, 50 m before). By using the speed immediately before passing in this way, the determination result screen can be displayed according to the actual timing of passing.

Specifically, the control unit 18 obtains V50 (traveling speed at 50 m before-limit speed), determines one of the determination result screens in relation to the set reference speed, and displays the speed difference. do. FIG. 19 (h) is a screen to be displayed when passing through in the best condition, and draws an image of running away and the characters of "Congratulations" against the background of the setting sun. It also outputs a voice saying "Congratulations". The specific conditions were | V50 | ≦ 2 km / h. In this way, the best situation is that the speed difference is small and the vehicle passes at a running speed near the speed limit.

FIG. 19 (i) is a screen to be displayed when the vehicle passes through in the second best condition, and the characters “Good” are drawn against the background of the setting sun. It also outputs a voice saying "Good". The specific conditions were 2 km / h << V50 | ≦ 5 km / h. If it becomes slower than necessary with respect to the speed limit, it may not be possible to ride on a smooth traffic flow due to the balance with the running speed of other vehicles, so even if it is slower than the speed limit, the rank will be lowered if the deviation becomes large. I made it.

FIG. 19 (j) is a screen to be displayed when the vehicle passes through in the third best condition, and the character "OK" is drawn against the background of the setting sun. It also outputs a voice saying "OK". The specific conditions were V50 <-5 km / h or + 5 km / h <V50 ≦ + 10 km / h. Even if the speed limit is too slow, it is not desirable to make a bad judgment, so I tried to separate the range of the auntie who is below the speed limit and the range of overspeed.

FIG. 19 (k) is a screen to be displayed when passing through in the fourth best (actually bad) situation, and the character "BAD" is drawn against the background of a cloudy sky. In addition, the voice of "BAD" is output. The specific conditions were 10 km / h <V50 ≦ 20 km / h.

FIG. 19 (l) is a screen to be displayed when the vehicle passes through in the worst situation, and the characters "JESUS" are drawn against the background of lightning. Also, the voice of "JESUS" is output. The specific condition was 20 km / h <V50.

In this way, the determination result screen is output when passing through the alarm target (Orbis), which makes it more game-like and more interesting. In addition, by driving carefully so that a better screen is output, the driver will also proceed in the direction of keeping in mind safe driving in the flow without decelerating more than necessary while suppressing overspeed. Can be urged.

FIG. 20A shows an example of a screen transition of a special alarm that is output when the distance to the alarm target (Orbis) is the second reference distance (for example, about 1000 m before) while traveling on a general road. .. While driving on a general road, "1. The distance between the vehicle and the target is 1100 m or less", "2. The vehicle orientation as seen from the warning target (Orbis) is within a predetermined angle (for example, ± 40 degrees)", "3. When all the conditions of "the target direction as seen from the traveling direction of the own vehicle is within a predetermined angle (for example, ± 90 degrees)" are satisfied, the control unit 18 notifies the special alarm shown in FIG. 18A. That is, the control unit 18 freezes the standby screen of the map, displays the alarm name (“loop coil” in the figure), and then performs an animation of breaking ice. The beginning of ice cracking is, for example, from the center of the screen. At this time, the sound effect is the sound of the glass breaking. At the same time as the animation starts, the control unit 18 blinks the full-color LED in red three times. As a result, the optical tubes 20 on both sides of the display unit 5 blink red three times.

Next, the control unit 18 shifts to the orbis animation (animation alarm of the second embodiment) corresponding to each type of alarm target. This display continues up to 600m. In addition, sound effects and voice output set for each alarm target are also performed.

FIGS. 20 (c) and 20 (d) are output when the distance to the warning target (Orbis) is the third reference distance (distance shorter than the second reference distance: for example, about 600 m before) while traveling on a general road. An example of the screen transition of the special alarm to be performed is shown. While driving on a highway, "1. The distance between the vehicle and the target is 600 m or less", "2. The direction of the vehicle as seen from the warning target (Orbis) is within a predetermined angle (for example, ± 40 degrees)", "3. When all the conditions of "the target direction as seen from the traveling direction of the own vehicle is within a predetermined angle (for example, ± 90 degrees)" are satisfied, the control unit 18 terminates the animation warning shown in FIG. Move to alarm. At the same time as switching, the control unit 18 controls the light emission of the full-color LED 22, and starts blinking the light tubes on both sides in red. This blinking is performed until the alarm has passed and the alarm has ended. Further, the control unit issues an alarm by voice output at a predetermined distance (for example, at 600 m and 300 m).

** Inspection control group (using location information) **
FIGS. 20 (e) and 20 (f) show an example of the screen transition of the special alarm to be output when the distance to the alarm target (inspection control) is the second reference distance (for example, about 1000 m before). "1. The distance between the vehicle and the target is 1100 m or less", "2. The direction of the vehicle as seen from the warning target (Orbis) is within a predetermined angle (for example, ± 40 degrees)", "3. When all the conditions of "the target orientation is within a predetermined angle (for example, ± 90 degrees)" are satisfied, the control unit 18 outputs the alarm screen shown in FIG. 20 (e). That is, the control unit 18 displays an animation in which an image like a black hole appears in the center of the standby screen of the map and the target name is displayed in the image. The black hole performs an animation that gradually increases in about 2 seconds, for example. At this time, the sound effect is a deep bass sound that echoes from the bottom of the ground. At the same time as the animation starts, the control unit 18 blinks the full-color LED in yellow three times. As a result, the optical tubes 20 on both sides of the display unit 5 blink in yellow three times.

Next, after the black hole animation is completed, the control unit 18 displays a live-action alarm for each alarm target in the figure (FIG. 20 (d)). The live-action alarm is a notification that changes the transparency of the live-action image to make it blink. This display continues up to 600m.

FIG. 20 (g) shows the screen transition of the normal version of the special alarm that is output when the distance to the alarm target (inspection control) is the third reference distance (distance shorter than the second reference distance: for example, about 600 m before). An example is shown. While driving on a highway, "1. The distance between the vehicle and the target is 600 m or less", "2. The direction of the vehicle as seen from the warning target (Orbis) is within a predetermined angle (for example, ± 40 degrees)", "3. When all the conditions of "the target direction as seen from the traveling direction of the own vehicle is within a predetermined angle (for example, ± 90 degrees)" are satisfied, an animation warning (Example 2) corresponding to the type of warning target is performed.

21 (a) to 21 (d) are special versions of special alarms that are output when the distance to the alarm target (inspection control) is the third reference distance (distance shorter than the second reference distance: for example, about 600 m before). An example of the screen transition of is shown. The condition for transition to the special version is that the radio alarm is received between 1100 and 600 m. When switching to the special version or later, the control unit 18 first displays the alarm screen shown in FIG. 21 (a). This alarm screen shows a state in which noise is generated in the entire map screen. It expresses the state of being broken by noise and attracts the user's attention. Further, at this time, the control unit 18 outputs a noise-like sound, for example, an alarm sound of "roughness". Next, after outputting the sound effect that the CRT television disappears, the backlight is turned off in all black as shown in FIG. 20 (b). Next, the control unit 18 outputs a predetermined dedicated sound effect, controls the full-color LED 22 to emit light in green and blue 100%, causes the optical tube 20 to emit light in a pale color, and displays the screen shown in FIG. 21 (c). indicate. For example, the character of ∞ is expressed by the cooperation of the optical tube 20 and the display unit 5 described with reference to FIG. Since the pale color represents the image of the lightning shining, the control unit 18 outputs a lightning sound effect at the same time. After that, an animation alarm corresponding to the type of alarm target shown in FIG. 21 (d) is output.

** Other POI group (using location information) **
FIG. 21 (e) shows an example of the alarm screen of the alarm target (other POI group). After animating the map screen with fog, the control unit 18 issues an animation alarm corresponding to the type of alarm target according to the reference distance of the alarm condition.

** Radar group **
FIG. 21 (f) shows an example of an alarm screen of an alarm target (radar group). The control unit 18 performs an animation in which the screen burns for a moment like a backdraft. The sound effect is a burning sound. After that, an animation warning corresponding to the type of warning target is performed according to the reference distance of the warning condition.

** Wireless group **
FIG. 21 (g) shows an example of an alarm screen of an alarm target (radio group). The control unit 18 performs an animation in which a blue lightning bolt is generated on a map screen. The sound effect is the sound of lightning falling. After that, an animation alarm corresponding to the type of alarm target is issued.

[Public control information display function]
The police in each prefecture announce the place and date of the crackdown as traffic disclosure crackdown information. Therefore, it is acquired in advance by data update processing. For example, the latest public control information data is downloaded to the database 19 or the like using the memory card 11. Then, since the control unit 18 has a function of notifying that the public control information has been announced at the current location, the control unit 18 accesses the public control information data downloaded based on the current position and publishes it at the current location. If the crackdown information has been announced, we will notify you to that effect. For such notification, for example, the display unit 5 is used. The display unit 5 may be used to output a mark or character meaning to notify that the public control information has been announced, or to emit light at a predetermined position of the display unit 5. Then, as light emission at a predetermined position, in the present embodiment, for example, as shown in FIG. 22A, the icon display unit 32b is illuminated in red to notify the light emission. More specifically, the control unit 18 arranges the warning lamp unit 71 in the background portion of the display area of the icon display unit 32b, and the warning lamp unit 71 blinks red radially to flush.

When it is detected that the display area of the icon display unit 32b and the warning lamp unit 71 is touched, the control unit 18 maps (Map) the public control information display unit 72 of the balloon-type text screen shown in FIG. 22 (b). Display on top of the screen). The public control information display unit 72 displays one control information per page. If there are multiple crackdown information, page it to display the next public crackdown information. That is, the left page move button 72c and the right page move button 72b are arranged on the left and right sides of the public control information display unit 72, and the return button 72a is arranged in the center of the upper side of the public control information display unit 72. .. The control unit 18 displays the page movement button in the direction with data, and hides the button in the direction without pages. Then, when the control unit 18 detects that the page movement buttons 72b and 72c are touched, the color of the pressed movement button is momentarily changed (for example, "purple"), and the page on the pressed side is displayed. ..

By doing so, the user can see the public control information one by one in a state of being displayed on the entire screen. That is, for example, if the side-scrolling method is used near the lower end of the display screen of the display unit 5 to notify the opening control information, if the first character is overlooked and viewed from the middle, until the first character appears again. It is necessary to keep looking at the display unit 5, which is not preferable. On the other hand, since the public control information for one case is displayed in a stationary state on the public control information display unit 72 as in the present embodiment, the user does not miss it because the viewing timing is bad. In addition, if the side-scrolling display is configured to automatically output public control information when, for example, there is public control information at the current location, users who do not want to see the information or are not interested in it or For users who already know the information, information that they do not want to read is output to the display unit 5, and the scrolling causes movement, which is annoying. On the other hand, in the present embodiment, the user who does not want to see the information does not have to touch the warning lamp unit 71, so that it is possible to prevent the output of unpleasant information.

Further, when it is detected that the return button 72a is touched in the state of FIG. 22B, the control unit 18 erases the public control information display unit 72 and displays the original Map screen. When the public control information is browsed once and then returned by the back button 72a, the icon displayed on the icon display unit 32b is displayed in red and white characters as shown in FIG. 22 (c) until the public control information is released. Change to 71'. Also, if the public control information is canceled, the icon will be returned to normal blue and white characters. In addition, when new public control information is received, it will be flushed again.

Further, for example, as shown in FIG. 22D, in the case of a screen without an icon display unit, the control unit 18 arranges a warning lamp unit 71 in the background portion of the character display area of the map scale, for example, at the current location. If there is public control information, the warning lamp unit 71 blinks red and radiates and flushes.

When it is detected that the display area of the warning lamp unit 71 is touched in this state, the control unit 18 displays the public control information display unit 72 of the balloon-type text screen shown in FIG. 22 (b) in FIG. 22 (d). ) Display Overlaid on the screen. Then, when it is detected that the back button 72a is touched, the control unit 18 erases the public control information display unit 72 and displays the original display screen. At this time, as shown in FIG. 22 (e), the map scale is changed to red and white characters 71'.

[Example of standby screen display function]
** Speed display standby screen **
FIG. 23 shows an example of a standby screen displayed by the standby screen display function of the control unit 18. FIG. 23A shows an example of the “speed display standby screen”. On this standby screen, an object 81 showing a running situation such as speed is displayed in the center of the screen. The object 81 has a configuration in which a compass 81b is arranged around the speedometer 81a. The speedometer 81a is an animation imitating a circular analog meter, and the needle 81c of the speedometer is moved according to the current speed. Further, a warning lamp 81d for notifying the overspeed is arranged at a predetermined position in the speedometer 81a. The warning lamp 81d indicates whether or not the current traveling speed is equal to or higher than the reference speed (for example, 120 km / h). The control unit 18 lights the warning lamp 81d in green when the traveling speed is less than the reference speed (for example, 120 km / h), and turns the warning lamp 81d in red when the traveling speed is equal to or higher than the reference speed (for example, 120 km / h). Light. The compass 81b has the initials of "N, NE, E, SE, S, SW, W, NW" indicating the surroundings arranged on the ring at intervals of 45 degrees, and the compass display unit 32d displayed on another display screen. Similarly, the vehicle is rotated and displayed so that the direction of travel of the vehicle is upward. The compass 81b is based on silver or metallic, and the characters "N" are red characters and the other characters are black characters. Since the traveling speed and the traveling direction (direction) can be known from this object 81, the own vehicle speed display unit 32c and the compass display unit 32d displayed on other screens are not displayed. According to this standby screen, the speedometer 81a and the compass 81b are displayed in a large size on the entire screen, so that they may be easy to see. Further, the ring-shaped compass 81b is fitted around the speedometer 81a to be integrated, and the compass 81b is drawn so as to be glossy like metal, which makes it cool.

** Acceleration standby screen **
FIGS. 23 (b-1) and 23 (b-2) show an example of the “acceleration standby screen”. This standby screen displays the state of acceleration applied to the vehicle with numbers and gradation. On this standby screen, an object 82 showing a situation such as the magnitude and direction of acceleration is displayed in the center of the screen, and a numerical display unit 83 for displaying the state of acceleration numerically is displayed on both the left and right sides. The object 82 displays the acceleration gauge 82b at a predetermined position around the vehicle 82a drawn in 3D.

The acceleration gauge 82b displays the direction in which the acceleration of the vehicle is applied based on the output of the built-in acceleration sensor 25. In the figure, since it is arranged on the front side (front grill side) of the vehicle 82a, the acceleration shows a state in which the acceleration is applied to the front of the vehicle, that is, a state in which the brake is applied and the vehicle is decelerating. Although not shown, an acceleration gauge 82b is placed on the rear side of the vehicle during acceleration, and around the vehicle 82a depending on the direction in which the vehicle turns and the speed state (acceleration, deceleration, constant speed) at that time. The acceleration gauge 82b is arranged at an appropriate position of.

Acceleration gauge 82b. As shown in FIG. 22 (b-2), five small sectors are arranged next to each other. The small fan shape in the center is the part that displays the acceleration value applied to the current vehicle. Each small sector is divided into a plurality of (for example, 11) blocks from the center to the periphery. Each block constitutes a memory of an acceleration gauge, and a color to be displayed is set for each block. The control unit 18 colors the small fan shape in the center up to the memory block corresponding to the acquired acceleration value, and makes the memory exceeding the acceleration value transparent. For example, in order from the center side, the color of this gauge is "white" for the 0th, "blue" for the 1st to 3rd, "yellow" for the 4th to 7th, and "red" for the 8th to 10th. In FIG. 22 (b-2), predetermined colors are displayed up to the maximum 10th scale (center is 0th). The first color on the center side is transparent, and is transparent regardless of the acceleration value. This is because the center side overlaps with the vehicle 82a, so that the display of the vehicle 82a is prioritized.

Further, the control unit 18 reduces the scale of the gauge by 2 on the small fan-shaped portion adjacent to the left and right of the central small fan, and further reduces the scale of the adjacent gauge by 4 on the scale. In the example of FIG. 22 (b-2), since the center is colored up to the 10th block, the small sector next to it is colored up to the 8th block, and the small sector next to it is colored up to the 6th block.

By using the acceleration gauge 82b, it becomes easy to intuitively recognize the direction in which the acceleration of the vehicle is applied and the magnitude of the acceleration value. Since the small fan shape is placed adjacent to the left and right of the central small fan shape that indicates the magnitude of acceleration, a certain width can be secured, making it easier to see, and the scale of the adjacent small fan shape is reduced, resulting in a pointed shape. The size is easy to understand, and the appearance is also novel. In addition, the acceleration gauge is drawn with a gradation that gradually changes the color, which makes it more beautiful and interesting. Further, for example, as the acceleration value becomes larger, the blue system is changed to the red system, so that the user can intuitively recognize that dangerous driving or non-eco-driving is performed due to a large acceleration.

Further, since the specific acceleration value is displayed on the numerical display unit 83, it can be understood accurately. Further, the maximum acceleration displays the maximum acceleration in a predetermined period. The predetermined period includes, for example, the period from the start of the engine to the present, the period up to a predetermined time before the present as a reference, the period from the present to the predetermined mileage, and the like. For example, it is preferable to provide a log function, record information on the current position and the acceleration at that time (output value of the acceleration sensor, etc.) at predetermined time intervals, and obtain and display the maximum value from the recorded history. When the target start point (for example, when the engine is started) is determined, for example, from the start of the engine to the present, the current acceleration value is compared with the recorded maximum acceleration value from the start point, and the current acceleration value is obtained. If is large, the maximum acceleration value may be updated.

** Positioning information standby screen **
FIG. 23 (c) shows an example of the “positioning information standby screen”. This standby screen displays the satellite position, satellite number, and reception level. On this standby screen, an object that displays the position of a satellite is displayed on the left side of the screen, and a graph is displayed on the right side of the screen. The object displays the satellite position with a "+" mark on the picture that imitates the earth. The control unit 18 obtains the position in the sky on the earth from the information of each GPS satellite acquired from the GPS receiver 13, indicates a "+" mark at the corresponding position, and further, the quasi-zenith satellite system (QZSS). ) Is displayed for two types of satellites, the quasi-zenith satellite "MICHIBIKI" and the meteorological satellite "Himawari", so that the relevant character information and the corresponding "+" mark are connected by a straight line. This makes it possible to see at a glance the existence of "Michibiki" and "Sunflower" and where they are. Further, it is preferable to have a function of displaying the numerical value of the satellite number of each received satellite having a high CN value and displaying the numerical value and the corresponding "+" mark so as to be connected by a straight line.

The graph is displayed from the left in order from the smallest satellite number of the captured satellite, and the CN value of each satellite is displayed as a bar graph. When 8 or more satellites are captured, the top 8 satellites are selected in order from the one with the highest CN value, and a graph in order of satellite number is created and displayed.

Further, in the present embodiment, when the CN value is 30 or more, the bar graph is green, when the CN value is 20 or more, the bar graph is yellow, and when the CN value is less than 20, the bar graph is red. It is preferable because the level of the CN value can be recognized not only by the height of the graph but also by the color. For example, if the entire graph is green, it can be confirmed that the CN values of all eight satellites are good.

** Driver's point standby screen **
FIGS. 23 (d-1) and 23 (d-2) show an example of the “driver's point standby screen”. This standby screen displays the result of scoring each item based on the driving data and obtaining the comprehensive evaluation of driving from the points of the items. For these driver's points, points for a predetermined determination item are obtained from the accumulation of running conditions for a certain period of time in the past, and a comprehensive evaluation is performed. The past fixed time to be determined is, for example, one hour. Even if it is less than one hour, such as at the beginning of operation, the judgment is made within the traveled range. Then, in this standby screen, the driver's point graph 84a is arranged on the left side of the screen, and the layout is such that the total points 84b, the rank badge 84c, and the title 84d are displayed in order from the top on the right side of the screen.

Judgment and calculation of driver's points are as follows. First, there are four specific judgment items: sudden acceleration, sudden deceleration, sudden steering, and economic speed. Each item is set to 100 points at the start, and points are set according to the driving conditions according to the rules shown in FIG. 24. Increase or decrease. The range of points is 0 to 100.

The control unit 18 displays each point of the four items as a pie chart on the driver's point graph 84a, and each numerical value of the four items is displayed as "○○ pt" next to or below the item of the graph. Further, the control unit 18 obtains the average of the numerical values of the four items, sets them as total points, and displays them at predetermined positions as numerical values.

Further, the rank badge 84c and the title 84d are determined by the combination of the ranks of the points of each of the four items. The rank badge 84c is an icon that imitates the five stars (highest rank) shown in FIG. 23 (d-1) and the two types of emblems (first emblem and second emblem) shown in FIG. 23 (d-2). do. The two emblems are higher on the left side and lowest on the right side. Further, a plurality of colors are prepared for each of the icons of these three types of rank chapters 84c. In the figure, the icon is gold, but silver and copper are also available. For the same icon form, gold is the highest level, then silver, and finally copper. Therefore, there are nine types of rank insignia 84c in all. Five-star (gold) is the highest in the ranking of these nine types of class emblems 84C, and the following are five-star (silver) → five-star (copper) → first emblem (gold) → first emblem ( Silver) → 1st emblem (copper) → 2nd emblem (gold) → 2nd emblem (silver) → 2nd emblem (copper). The control unit 18 determines one of the nine types of rank insignia based on each numerical value of the four items, and displays it at a predetermined position. The determination of this rank insignia may be made based on, for example, a combination of each numerical value of four items and a correspondence relationship of the rank insignia to be used. The title to be used should also be associated. For example, divide the numerical value of each item into multiple levels.

As an example,
A: 80 <A ≤ 100 (excluding ALL 100)
B: 50 <B ≦ 80
C: 0 ≤ C ≤ 50 (excluding ALL 0)
Divide into three levels. Then, for example, the correspondence table as shown in FIG. 25 is registered in the database 19. When the numerical value of each of the four items is obtained, the control unit 18 classifies the ABC level, accesses the database 19, identifies the corresponding class insignia and title, and outputs the value to the predetermined position of the display unit 5. Further, when outputting the title, the character color of the table shown in FIG. 25 is used. In addition, the rank insignia and title will not be displayed within 10 minutes of running. Further, the data one hour or more ago is deleted. Data should be retained even when Power is turned on / off.

As for the rank insignia and title, the higher the total points, the better the user's praise and the user's mood. In line with this, in the above-described embodiment, three colors of gold, silver, and copper are prepared even in the same form, and even in the same form, the rank badge is further divided into three levels (gold is the first and copper is the third). did. Also, for example, in police and other institutions, it is advisable to imitate the emblem worn by a person with a higher position as the total points increase, according to the type of emblem that changes depending on the position. You may also try to increase the number of stars. On the contrary, the lower the total points, the better the content is that the user feels sick or depressed. In the embodiment without this, if all the items are 0, the rank insignia is omitted. In addition, the title should be such that the lower the total points, the less likely it is to be hung up, and the more disgraceful it is. In this way, the user will not feel sick or disgraceful, and will drive safely and eco-friendly so that he / she can receive a rank insignia or title that makes him / her feel better. ..

** Tilt standby screen **
FIG. 23 (e) shows an example of the “vehicle tilting standby screen”. This standby screen is displayed as an illustration of a horizontal line based on, for example, the inclination of the vehicle acquired as OBD information. Further, a tilt sensor may be mounted on the radar detector, and the tilt of the vehicle may be obtained and displayed based on the output of the tilt sensor.

[Example of setting screen]
When making various settings such as the operation mode of the radar detector, for example, when the display unit 5 displaying the main screen or other predetermined screen is touched, the control unit 18 displays the setting screen. The operation mode and the like are switched and set based on the touch of the button area prepared at the predetermined position on the displayed setting screen. Then, in the present embodiment, the input device element imitating the mechanical input device is displayed on the setting screen. Examples of the mechanical input device element include an image of a "toggle switch" as shown in FIG. 26 (a) and an image of a "volume knob" as shown in FIG. 26 (b). In particular, when the movement of an actual input device is discrete (for example, a “click” feeling) such as a “toggle switch”, the input device element is also displayed with a movement that matches the actual movement. Further, when an operation sound (for example, "click") is generated due to the operation, the operation sound is output according to the movement of the input element. By doing so, the machine / equipment-likeness is brought out, and the setting screen is full of playfulness. Therefore, for example, it is preferable for a user who likes machines because it gives a feeling of familiarity.
