Description

  The present invention relates to a system and a program for informing when an alarm condition is satisfied.

  In recent years, many speed measuring devices for measuring the speed of an automobile have been installed around the road. As an example of a speed measuring device, a microwave of a predetermined frequency band is emitted toward a vehicle, and the reflected wave is received to measure the traveling speed of the vehicle.

  On the other hand, in order to detect the presence of such a speed measuring device, a microwave detector configured to detect a microwave emitted from the speed measuring device and output an alarm is conventionally known. However, depending on the installation location of the speed measurement device, road conditions, and other surrounding environments, conventional microwave detectors can be detected from a relatively long distance, and can be detected only after a relatively close distance. .

Also, some velocity measuring devices cannot be detected by conventional microwave detectors.
As an example, there is a type in which a loop-shaped coil is embedded in the ground and a vehicle speed is determined while detecting the vehicle passing over the coil, as called a loop type. Others detect the speed of the vehicle using light other than microwaves.

Therefore, recently, the installation position information of the speed measuring device is stored in advance, and GPS (Global
Positioning System) In-vehicle electronic devices that issue a warning regardless of the presence or absence of microwave detection when the current position approaches the stored installation position using information (when a predetermined relationship is reached) Yes (Patent Document 1).

  For example, when the current position is within 1000 m from the installation position of the speed measurement device, the first warning is given, and when the current position is within 500 m from the installation position of the speed measurement device. Do a second warning, etc.

  As specific notification modes, for example, “Left direction 1 km ahead expressway H system”, “Immediately ahead general road N system” and the contents specifying the target content as voice information Outputting from a speaker or displaying characters or images directly representing those alarm targets on a display unit is performed. The image directly representing the alarm target includes an actual photograph obtained by capturing the alarm target such as a speed measuring device, and an image imitating the photograph.

  Further, since the screen size of the display unit becomes larger and the screen becomes a color screen, the types and amounts of information output using the display unit are also increasing. As an example of the information to be output, there is a map around the vehicle position, and by displaying a mark indicating the vehicle position and a mark (2D, 3D) indicating the alarm target on the map, a specific example is displayed. The positional relationship can be recognized. Furthermore, the background color is changed depending on the type of the alarm target being notified, and the background color is changed to red when the distance from the alarm target is closer than the reference value.

JP 2008-64588 A

  Conventional devices increase the amount of information provided by using the display unit as the screen size of the display unit increases. However, since the driver who is driving needs to look around the vehicle ahead and other vehicles, he / she pays attention to the display unit. It can be difficult, and it can be difficult to instantly understand the content of the information provided. For example, when a large amount of information is output to the display unit at a time, the user cannot see all the displayed information and may miss important information. Further, when a map is displayed on the display unit, it is difficult to see the map if the distance between the current position and the alarm target is less than the reference distance and the background color is changed to red or the like. In particular, in the case of a map, roads and the like are displayed in different colors, and there are various problems that it becomes more difficult to see if the color of the road and the changed background color are the same color system.

In order to solve the above-described problems, the system according to the present invention has (0) a function for displaying information on the display screen and, when an alarm condition is satisfied, controls the light emission state of the light emitting unit to notify the alarm. And a function of causing the display screen to emit light in a luminescent color corresponding to an alarm target that satisfies the alarm condition, and when the alarm condition is satisfied. The light emitting unit has a function of displaying a color similar to the light emission color of the light emitting unit, and the light emitting unit is configured to emit a logo in the light emitting color. A system having a function of displaying information on a display screen and a function of controlling a light emitting state of a light emitting unit to notify an alarm when an alarm condition is satisfied, and as the light emitting state control, A light emitting color corresponding to an alarm target that satisfies an alarm condition, and a function that causes the display screen to display a color similar to the light emitting color of the light emitting unit when the alarm condition is satisfied, the light emission The part has a configuration in which a peripheral region including a logo emits light in the emission color.
(1) A system comprising control means for controlling a light emission state of a light emitting unit using an LED as a light source to notify an alarm when an alarm condition is satisfied, wherein the control of the light emission state is based on the alarm condition. It was made to emit light with a light emission color corresponding to the alarm target that was satisfied.

  A light emitting unit equipped with an LED means that the light source of the light emitting unit is an LED. When the LED is exposed, the LED itself becomes a light emitting part, and when the LED is built in the case main body (housing) of the apparatus, an area where it can be seen that light is emitted from the outside of the case main body is the light emitting part. It becomes. In the latter case, for example, a predetermined region on the surface of the case main body is the light emitting unit. For example, the predetermined region is made of a member that thins the wall surface of the case body so that light from the LED is transmitted, or a member that opens a window hole in the wall surface of the case body and transmits light such as translucent to the window hole. It may be configured by attaching a cover.

The light emitting unit emits light with a light emission color corresponding to the alarm target that satisfies the alarm condition. For example, the relationship information that associates the alarm target with the emission color information is stored and held in a predetermined storage unit. The light emission color information is information for specifying what the light emission color is. When the alarm condition is satisfied, the control means acquires the emission color information corresponding to the alarm target satisfying the alarm condition from the relation information stored by accessing the storage means and specified by the emission color information. The light emission of the LED is controlled so as to obtain a light emission color. Alarm conditions are based on location information, for example, the positional relationship between the alarm target and the current location is a predetermined approach relationship, or are not based on location information such as reception of predetermined radio waves / radio signals, vehicle status / driving status, etc. There is. As the one not based on the position information, as shown in the above example, the one based on information from the outside of the vehicle such as reception of a predetermined radio wave, and the sudden start / steep handle (the sensor value of the acceleration sensor exceeds the reference value) ) Based on information in the vehicle (vehicle itself / driver), such as driving with poor fuel efficiency, such as dangerous driving.

  The emission color corresponding to the alarm target, but in the case of an alarm target based on position information, for example, the emission color may be set (associated) for each alarm target for which position information is registered. You may set a luminescent color for every. Also, when each type of alarm target is set, as shown in some examples in the embodiment, it is set for each type such as a fixed speed measurement device (radar), N system, traffic monitoring point, inspection area, road station, etc. Alternatively, it may be divided into a plurality of groups according to the importance (risk level), and the emission color may be set for each group, and the alarm targets belonging to the same group may have the same emission color. The correspondence of emission colors based on importance is, for example, red for those with high importance such as speed measuring devices, blue for those with medium importance (giving attention) such as N system, demand for roadside stations, etc. The one with low degree (the degree of information provision) should be green.

  The driver needs to be careful about the front and other surroundings while driving. In the present invention, when the alarm condition is satisfied, the light emitting unit emits light with the light emission color corresponding to the alarm target, so that the driver emits light even if the system device (light emitting unit) is not in view. The light emission part can be caught in the field of view and the emission color can be confirmed by shifting the line of sight a little. Thereby, it is possible to know that there is an alarm target that satisfies the alarm condition, what the alarm target is, and the like. A large number of alarm information is not reported, and since it is a simple alarm that emits light with a predetermined emission color, the driver can understand the alarm contents without gazing at the light emitting part for a long time. Focus on collecting information necessary for driving.

  (2) The LED is a color LED, and the control means may change the emission color step by step according to an alarm level. By using a color LED, a variety of colors can be expressed with a single LED. For example, using RGB primary color LEDs and color intensity control using PWM, if R is 5 bits, G is 5 bits, and B is 5 bits in total, 32,768 colors can be controlled. If R is 8 bits, G is 8 bits, and B is 24 bits in total, that is, 24 bits in total, 16,777,216 colors can be controlled. Therefore, it is possible to give an alarm that the emission color gradually changes by performing gradation control smoothly from a low alarm level to a high alarm level. When notifying the information about the alarm level on the conventional display screen, for example, in order to notify the signal level of the received radio wave, the alarm level is divided into, for example, five levels, and light is emitted every time the level increases by one. The level meter was used to increase (extend) by one, but by performing a control that gradually changes the emission color according to the alarm level, the alarm level can be expressed in analog form, A sense of quality increases. For example, the emission color may be changed from blue to red as the alarm level increases.

  (3) The control means may change the light emission intensity of the LED according to an alarm level. The light emission intensity can be changed by changing the lightness and brightness of the light emission color, for example. For example, the luminance can be changed by using the luminance PWM, and the color and brightness of the LED can be set by other known methods (methods specified by the LED manufacturer). Further, the light emission amount itself may be changed by adjusting the voltage applied to the LED. The effect similar to the above can be expected by changing the emission intensity instead of changing the emission color as in the invention of (2). Further, the change of the emission color and the change of the emission intensity may be performed together. For example, the emission intensity may be changed from a dark color to a bright color or the emission amount may be increased (increased) as the alarm level increases.

  (4) The alarm condition may be reception of radio waves, and the alarm level may be a signal level of the received radio waves. For example, when a radio wave of a predetermined frequency that is an alarm target, such as a microwave emitted from a speed measuring device, is received, an inorganic color can be changed by changing the emission color or emission intensity in accordance with the signal level of the received radio wave. Instead of using a digital radar level meter, the received signal level can be expressed in analog form.

  (5) The alarm condition is that the current position and the alarm target are in an approach relationship, and the alarm level may be the degree of the approach relationship. The degree of the approach relationship is controlled such that, for example, the alarm level becomes higher as the distance gets closer. This is preferable because the approximate remaining distance to the alarm target can be understood.

  For example, the alarm level may include, for example, the level of dangerous driving (the higher the sensor value of the acceleration sensor, the higher the level of dangerous driving), There are various types such as high fuel consumption per unit time, rapid acceleration, etc.).

  (6) The emission color may be changed by changing the frequency of the emission color in a stepwise manner corresponding to the alarm level. The emission color can be changed continuously by changing the frequency. In this case, smooth gradation control may be performed with the alarm level being 1 for the lower frequency and the alarm level being the maximum for the higher frequency.

  (7) It is preferable that the control unit has a function of performing an alarm by voice when the alarm condition is satisfied, and the control unit changes the light emission intensity of the LED corresponding to the strength of the voice. When the alarm condition is satisfied, for example, when the information about the alarm target such as “1 km ahead is a loop coil, the speed limit is 60 km” or “N system is immediately ahead” is spoken, the driver turned forward. It is preferable because the contents can be known in the state. In this case, by changing the light emission intensity (brightness, brightness, etc.) according to the strength of sound production (for example, volume), the device itself will feel like it is singing with will, increasing the sense of luxury and making it interesting It is good because it increases. It is preferable that the intensity of light emission be stronger (larger) as the sound is stronger (larger).

  (8) The control unit has a function of notifying information on a display screen, and the control unit emits light from the light emitting unit without changing a background color of the display screen when the alarm condition is satisfied. It is good to control. If the alarm condition is satisfied when various information is output on the display screen, for example, if the background color of the display screen is changed to red, etc. The information that was originally provided becomes difficult to see, which is not preferable. On the other hand, in the present invention, by changing the light emission state of the light emitting unit without changing the background color of the display screen, the driver is notified of the presence of the alarm target, and is inherently displayed using the display screen. It is preferable because the information that has been stored does not become difficult to see.

  (9) On the premise of the above invention (8), the information may be map information. The map information, for example, displays roads in different colors. If the background color is a color similar to the road color when the alarm condition is satisfied, the road becomes difficult to see. In particular, in the case of warning notifications, the background color is often displayed in red, and the road color is often displayed in red on the main roads such as national roads. If it changes, it will cause the problem that it becomes difficult to confirm the main road. On the other hand, the present invention does not change the background color of the display screen, which is preferable because the contents of a map such as a road can be easily and accurately understood even during an alarm (light emitting part is emitting light).

  (10) On the premise of the above invention (8) or (9), the control means may display alarm information on the display screen when the alarm condition is satisfied. By displaying the alarm information on the display screen, the user can be notified of more specific and detailed contents. In this case, it is possible to notify the user of the presence of the alarm target by the light emission of the light emitting unit provided separately from the display screen. In other words, instead of mixing multiple pieces of information on the same screen, the presence of the alarm target is performed on the display unit provided outside the display screen, and the detailed content uses the display screen. The user can achieve the object without looking at the display screen, and the user who wants to know the detailed contents can achieve the object by looking at the alarm information displayed on the display screen.

  (11) On the premise of the invention of the above (10), the alarm information is character information, and the color of the character information and the emission color of the light emitting unit may be similar colors. Using text information makes it easier to understand the content. At this time, by making the emission color of the light emitting unit and the color of the character information similar, the association between the display unit and the alarm information (character information) is strengthened, and the user can use the alarm information displayed on the display screen as the alarm information. This is preferable because the location of the character information can be easily found.

  (12) The alarm condition includes a plurality of conditions, and the control unit is configured to change a light emission state when the plurality of conditions are all satisfied and a light emission state when a part of the plurality of conditions is satisfied. Good. If some conditions are met, then all conditions may be met after that. Therefore, a warning may be given to the user by giving a warning when some conditions are satisfied. The light emission state when some of the conditions are satisfied may be less conspicuous than the light emission state when all the conditions are satisfied.

For example, as a plurality of conditions, “reception of a microwave (radio wave) of a predetermined frequency” (condition 1) and “the received signal level is equal to or higher than a reference value” (condition 2) satisfy two conditions. Then, an alarm is issued based on a predetermined light emission state (for example, red light emission) on the assumption that a radio wave emitted from an alarm target has been received. If only condition 1 is satisfied (the signal level is less than the reference value), a different light emission state (for example, Alarm by blue light emission). Even if the distance to the alarm target is long and the received signal level is less than the reference value, it is often the case that the signal level becomes higher than the reference value by further running and approaching the alarm target. In such a case, by giving a warning warning in advance, it is possible to prepare the user's mind so that even if an alarm that satisfies all the conditions is issued, safe driving can be performed without panic.

  (13) The light emitting unit may be configured to emit one color when viewed from the outside. When one color is emitted when viewed from the outside, it is sufficient that the light emitting portion seen from the outside emits only one color, and even if a plurality of light sources are incorporated, the light is not emitted simultaneously or is emitted simultaneously. In some cases, one color is obtained by emitting the same color. In addition, for example, LEDs of different colors are arranged close to each other, and the surface is covered with a cover such as white (translucent). Then, one or a predetermined number of LEDs may emit light, and the light that passes through the cover and is emitted to the outside may be one color of the combined color of the emitting LEDs. By setting the emission color to one, it is possible to easily understand what alarm target is the alarm.

  (14) The program of the present invention is a program for causing a computer to realize the function as the control means in the system according to any one of (1) to (13).

  According to the present invention, when the alarm condition is satisfied, the light emitting unit using the LED as the light source emits an alarm with a predetermined emission color corresponding to the alarm target, so that the user does not have to watch the light emitting unit. The presence / absence of the light emission and the light emission state (light emission color) can be recognized to know the presence of the alarm target.

More specifically, when the control unit 18 has update information such as new alarm target information (position information such as longitude / latitude, type information, etc.) as data stored in the memory card 11, the update is performed. Data is updated by storing (downloading) the information in the database 19.

  The database 19 can be realized by a nonvolatile memory (for example, EEPROM) in the microcomputer of the control unit 18 or externally attached to the microcomputer. The database 19 stores map data and information related to a certain alarm target at the time of shipment, and data and the like regarding the alarm target added thereafter are updated as described above.

  A GPS receiver 13 is arranged in the upper center of the back side of the case body 2, and a microwave receiver 14 and a radio receiver 15 are arranged next to the GPS receiver 13. The GPS receiver 13 receives GPS signals from GPS satellites and outputs current position (longitude / latitude) information. The microwave receiver 14 receives a microwave having a predetermined frequency emitted from the velocity measuring device. The wireless receiver 15 receives incoming radio waves having a predetermined frequency. A speaker 16 is also built in the lower part of the case body 2. The speaker port is provided on the bottom surface of the case body 2.

  A DC jack 17 is disposed below the back side of the case body 2. The DC jack 17 is for connecting a cigar plug cord (not shown), and is connected to a cigar socket of the vehicle via the cigar plug cord so that power can be supplied.

  The GPS log function is a function in which the control unit 18 stores the current position detected by the GPS receiver 8 every second in association with the detected time and speed (vehicle speed) in the nonvolatile memory as a position history. This position history is recorded in the NMEA format, for example.

  The standby screen display function is a function for displaying a predetermined standby screen on the display unit 5. FIG. 3A shows an example of a standby screen. Here, the speed, latitude, longitude, and altitude of the host vehicle detected by the GPS receiver 13 are shown.

  As shown in FIG. 3B, the MAP display function is a function for accessing the database 19 based on the current position detected by the GPS receiver 13, and reading and displaying the map data stored therein. In addition, the MAP display function searches the alarm target around the current position based on the position information stored in the database 19, and indicates the alarm target at a corresponding position on the map when there is an alarm target around. A function of displaying information (such as the target icon 112) in an overlapping manner is also provided. The specific display mode is as follows.

  The control unit 18 displays a map in the main display region R1 on almost the entire surface of the display unit 5 so that the traveling direction of the vehicle is always directed upward. The control unit 18 displays the map so that the lower center of the main display region R1 is the current vehicle position, and displays the vehicle icon 111 at the position.

  The control unit 18 displays status information in the status area R2 set above the main display area R1. Status information displayed in the status area R2 includes, in order from the left, the current time 121 (“15:10” in the figure), the GPS radio wave reception level display icon 122 (three straight lines of different lengths in the figure in parallel). Standing maximum reception level), parking prohibited area icon 123 (displayed when parking is in the highest priority area, parking priority area), and reception sensitivity mode display icon 124 (in the figure, “SE” having the highest sensitivity) indicating the reception sensitivity of the radar. ), Vehicle speed 125 (“30 km / h” in the figure), and azimuth magnetic needle 126. The status area R2 is a transparent area and is arranged using a layer above the layer of the main display area R1. As a result, even in the status area R2, the map located on the lower side can be visually recognized at the place where the status information is not displayed.

  The control unit 18 displays the current scale information (scale) in the scale display region R3 set on the left side of the main display region R1. The scale displays the distance from the vehicle position to the middle position in the vertical direction of the main area R1 ("500" in the figure) and the distance to the upper position ("1000" in the figure). To do. The unit is “m”. When detecting 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 (position along the scale display area R3) in the main display area R1 (illustrated). (Omitted), the map scale is changed according to the touch on 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 changed scale of the map scale, and also changes the scale information displayed in the scale display area R3.

  While executing the standby screen display function as shown in FIG. 3A, the control unit 18 that has detected a single touch on the display unit 5 displays a predetermined menu screen. Upon detecting that the screen switching button prepared in the menu screen has been touched, the control unit 18 switches to the MAP display function as shown in FIG. Similarly, the control unit 18 that detects a single touch on the display unit 5 during execution of the MAP display function displays a predetermined menu screen.

The priority of each function is set in the order of radar wave warning function, radio alarm function, and GPS alarm function from the highest.

  The GPS alarm function is a process executed at predetermined time intervals (1 second intervals) by an event from a timer included in the control unit 18 and detected by the latitude and longitude of the alarm target stored in the database 19 and the GPS receiver 13. When the distance between the two is obtained from the latitude and longitude of the current position, and the obtained distance becomes a predetermined approach distance, a GPS alarm display 130 (a schematic diagram of an alarm target) as shown in FIG. The remaining distance, etc.) is output, and an approach warning sound indicating that is output from the speaker 16.

For example, when a control radio is received, a voice is output like “control radio. Speed attention”.

[Alarm function using color LED]
The alarm function using the color LED, which is a feature of the present invention, will be described below. A light emitting unit 21 is provided at a predetermined position on the front surface of the case body 2. The installation position of the light emitting unit 21 is set at a central portion further above the display screen of the display unit 5. A color LED 22 is disposed inside the case body 2 facing the light emitting unit 21. The color LED 22 is an RGB three-primary-color LED, that is, an LED incorporating a chip of three primary colors. If R is 5 bits, G is 5 bits, and B is 5 bits in total, the color control of 32,768 colors is performed. For example, the light emitting unit 21 can make the light emission color of the built-in color LED 22 visible from the outside by thinning a corresponding region of the front wall surface constituting the case body 2 or fitting a translucent member. Further, the light emitting unit 21 emits one color as viewed from the outside.

  The control unit 18 controls the light emission state of the color LED 22. That is, the database 19 stores and holds relationship information that associates the alarm target with the emission color information. This related information is registered at the time of shipment as one piece of information related to the alarm target. In the present embodiment, the emission color information is not related to each alarm target, but is related to each type of alarm target. That is, the light emission color to be displayed for each type such as the fixedly installed speed measuring device (radar), N system, traffic monitoring point, inspection area, road station, etc., enumerated above as the alarm target in the GPS alarm function is specified. The emission color information to be related is related. Furthermore, emission color information that identifies the emission color corresponding to the speed measurement device (the alarm condition is signal detection corresponding to microwaves in a predetermined frequency band) that is the alarm target in the radar wave alarm function, and the detection target in the radio alarm function The emission color information for specifying the emission color corresponding to each wireless type is related.

  FIG. 5 shows the function of the control unit 18 that controls the light emission state of the light emitting unit 21 (color LED 22). In the control of the light emission state for the light emitting unit 21 (color LED 22) in the control unit 18, when there is an alarm target that satisfies the alarm condition, the color LED 22 is caused to emit light with the emission color corresponding to the alarm target, and the alarm target that satisfies the alarm condition is satisfied. When there are a plurality of the LED's, one of them is set as an alarm target (target) to be notified, and the color LED 22 is caused to emit light with the emission color corresponding to the alarm target as the target. Specifically, the control unit 18 executes the flowchart shown in FIG.

  First, the control unit 18 determines whether or not a predetermined microwave is received by the microwave receiver 14 (S1). When the control unit 18 receives the microwave (S1 is Yes), the control unit 18 accesses the database 19 to the speed measurement device associated with the reception of the microwave recorded in the relation information that associates the alarm target and the emission color information. The corresponding emission color information is acquired, and the color LED 22 is controlled to emit light with the emission color A specified by the emission color information. The light emission color A is preferably a color such as red that can be seen to have a high degree of urgency.

  On the other hand, when the predetermined microwave is not received (S1 is No), the control unit 18 determines whether or not the predetermined radio signal is received by the radio receiver 15 (S3). When the control unit 18 receives a predetermined radio signal (S3 is Yes), the control unit 18 accesses the database 19, and the radio type of the received radio signal recorded in the relation information that associates the alarm target and the emission color information. The color LED 22 is controlled to emit light with the light emission color B specified by the light emission color information. The emission color B actually differs depending on the wireless type, and for example, an appropriate color is set according to the level of urgency of the wireless type.

  In addition, depending on the type of radio, a color such as red that indicates a high degree of urgency is associated, but in this case, the urgency is lower than the emission color associated with the speed measurement device associated with the microwave reception described above. It should be a color that can be understood. For example, the color that shows that the degree of urgency is low may be, for example, less reddish or reduced in brightness and / or brightness.

  On the other hand, when the predetermined radio signal is not received (No in S3), the control unit 18 acquires the current position information detected by the GPS receiver 13, and whether there is an alarm target that has a predetermined approach relationship around it. It is determined whether or not (S5). That is, the control unit 18 accesses the database 19 based on the acquired current position, and determines whether or not a target alarm target exists around the current position. The target alarm target is the surroundings of the vehicle (for example, within a predetermined angle range with respect to the traveling direction (for example, an angle of 90 degrees or less on each of the left and right with respect to the traveling direction, and particularly preferably 45 degrees or less) In the case where there is one alarm target in a fan-shaped area having a radius Xm (X is a reference distance, etc.), the alarm target is the target. Become a target. Such a condition is within a predetermined angle range with respect to the traveling direction and is the closest.

  When there is a target alarm target based on the position information (Yes in S5), the control unit 18 accesses the database 19 and records the target recorded in the relationship information that associates the alarm target with the emission color information. The emission color information corresponding to the type of the alarm target is acquired, and the color LED 22 is controlled to emit light with the emission color C specified by the emission color information. This emission color C actually differs depending on the type of alarm target. Highly important devices such as speed measuring devices are red, those with medium importance (giving attention) such as N system are blue, and demand for roadside stations is low (information provision degree) ) Good things like green.

  The driver needs to be careful about the front and other surroundings while driving. In the present embodiment, when the alarm condition is satisfied, the light emitting unit 21 emits light with a predetermined light emission color corresponding to the alarm target. Therefore, even if the radar detector (light emitting unit 21) is not in view, It can be seen that the light has been emitted, and the light emission part 21 can be caught in the field of view and the color of the light emission can be confirmed by slightly shifting the line of sight. Thereby, it is possible to know that there is an alarm target that satisfies the alarm condition, what the alarm target is, and the like. The alarm by the predetermined emission color uses a light emitting unit 21 having the color LED 22 as a light source, so that a large number of alarm information is not notified and is a simple alarm of light emission in a predetermined emission color. Therefore, since the driver can understand the alarm contents without gazing at the light emitting part for a long time, the driver can concentrate on collecting information necessary for driving inside and outside the vehicle.

[Alarm sharing with display]
As described above, when the alarm is performed by the color LED 22 (light emitting unit 21), the alarm by the display unit 5 may not be performed or may be performed in combination. When used together, the target icon 112, the GPS alarm display 130, and the alarm screen 131 displayed on the display unit 5 are displayed and notified, and an alarm using a predetermined emission color by the color LED 22 (light emitting unit 21) is displayed. Set the same alarm target (target).

  And the control part 18 controls to make it a predetermined | prescribed light emission state, without changing the background color of the display part 5, when warning conditions are satisfy | filled. Since the background color is not changed in this way, the map information or the like displayed on the display unit 5 does not become difficult to see, and the information originally displayed on the display unit 5 and provided to the user can be notified as it is.

  Furthermore, in the present embodiment, the control unit 18 displays various types of alarm information on the display unit 5 when the alarm condition is satisfied, so that the user can be notified of more specific and detailed contents. In this case, it is possible to notify the user of the presence of the alarm target by light emission of the light emitting unit 21 provided separately from the display screen. In other words, instead of mixing multiple pieces of information on the same screen, the presence of the alarm target is performed on the display unit provided outside the display screen, and the detailed content uses the display screen. Can achieve the purpose from the light emission state of the light emitting unit 21 without looking at the display screen, and the user who wants to know the detailed contents can achieve the purpose by also viewing the alarm information displayed on the display screen. .

  Furthermore, the control unit may use character information when performing an alarm using the display unit 5. In this case, the color of the character information and the light emission color of the light emitting unit 21 may be similar colors. Using text information makes it easier to understand the content. At this time, by making the light emission color of the light emitting unit 21 and the color of the character information similar, the association between the light emitting unit 21 and the alarm information (character information) is strengthened. Therefore, it is preferable because the user can easily find the location of the character information as the alarm information displayed in the display unit 5.

[Other examples of changing the emission color depending on the alarm target]
In the embodiment described above, the emission color is changed corresponding to the type of alarm target. However, the present invention is not limited to this. For example, in the case of an alarm target based on position information, the alarm target in which position information is registered. The emission color may be set (associated) for each group, or divided into a plurality of groups according to importance (risk level), and the emission color is set for each group. Also good.

  In the above-described embodiment, when red is used in the emission color B by the wireless alarm function, the urgency is lower than the red color of the emission color B by the radar wave alarm function. However, the same color may be used. .

[Changing the lighting status depending on the alarm level]
In the embodiment described above, the emission state is controlled by changing the emission color corresponding to the alarm target. However, the present invention is not limited to this, and the emission state may be changed according to the alarm level. By using a color LED, a variety of colors can be expressed with a single LED. Therefore, it is possible to give an alarm that the emission color gradually changes by performing gradation control smoothly from a low alarm level to a high alarm level. Then, the change in the light emission state depending on the alarm level may be changed to the change in the emission color as described above, or the emission intensity of the color LED 22 may be changed along with the change. The light emission intensity is changed by, for example, the control unit 18 changing the lightness or brightness of the light emission color (for example, using a PWM for brightness) or adjusting the applied voltage of the LED to change the light emission amount itself. When changing the light emission intensity, for example, as the alarm level increases, it is preferable to change from a dark color to a bright color, or to increase (increase) the light emission amount.

  For example, when the alarm condition is reception of radio waves, the signal level of the received radio waves may be used. When a radio wave of a predetermined frequency that is an alarm target, such as a microwave emitted from a speed measurement device, is received, an inorganic digital radar is changed by changing the emission color or intensity of the emission in accordance with the signal level of the received radio wave. The received signal level can be expressed in analog form instead of a level meter.

  Further, when the alarm condition is that the current position and the alarm target are in an approach relationship, the alarm level may be the degree of the approach relationship. The control based on the degree of the approach relationship is, for example, a control in which the alarm level becomes higher as the distance gets closer. In this way, the approximate remaining distance to the alarm target can be understood. That is, when emitting the emission color C in FIG. 5, the control unit 18 performs control to change the emission color based on the remaining distance to the alarm target based on the emission color based on the alarm target.

  Further, there are various alarm levels such as the degree of dangerous driving and fuel consumption, in addition to the above-described reception and approach relation of the predetermined radio wave. The degree of dangerous driving is set such that, for example, an acceleration sensor is provided, and the degree of dangerous driving is higher, that is, the alarm level is higher as the sensor value of the acceleration sensor is larger. In addition, since the fuel consumption becomes worse as the vehicle accelerates more rapidly, it is determined based on the sensor value of the acceleration sensor that the fuel consumption is worse as the sensor value is larger. The fuel consumption may be obtained from vehicle information provided from the vehicle. The OBD-II (II is the Roman numeral “2”, hereinafter “OBD-II” is referred to as “OBD2”) connector mounted on the vehicle is also referred to as a failure diagnosis connector and is connected to the ECU of the vehicle. Various vehicle information is output. Therefore, the connection cable connected to the OBD2 connector is attached to the case body, such as MAF value (mass air flow), injection opening time, throttle opening, fuel flow, instantaneous fuel consumption, remaining fuel amount, accelerator opening, etc. Get vehicle information. For example, the control unit 18 obtains the fuel consumption from the MAF value, or obtains the current fuel consumption based on the instantaneous fuel consumption output as the vehicle information.

  On the other hand, the light emission state corresponding to the alarm level is changed. For example, the light emission color may be changed by changing the frequency of the light emission color stepwise. The emission color can be changed continuously by changing the frequency. In this case, smooth gradation control may be performed with the alarm level being 1 for the lower frequency and the alarm level being the maximum for the higher frequency.

[Combination with alarm by voice]
The control hand unit has a function of issuing an audio alert from the speaker 16 when the alarm condition is satisfied. And a control part is good to change the emitted light intensity of LED corresponding to the strength of an audio | voice. When the alarm condition is satisfied, for example, when the information about the alarm target such as “1 km ahead is a loop coil, the speed limit is 60 km” or “N system is immediately ahead” is spoken, the driver turned forward. It is preferable because the contents can be known in the state. In this case, by changing the light emission intensity (brightness, brightness, etc.) according to the strength of sound production (for example, volume), the device itself will feel like it is singing with will, increasing the sense of luxury and making it interesting It is good because it increases. It is preferable that the intensity of light emission be stronger (larger) as the sound is stronger (larger).

[Alarm by complex condition]
The alarm condition may be a plurality of conditions (combined conditions). In this case, the control unit 18 may make the light emission state when the plurality of conditions are all satisfied different from the light emission state when a part of the plurality of conditions is satisfied. If some conditions are met, then all conditions may be met after that. Therefore, a warning may be given to the user by giving a warning when some conditions are satisfied. The light emission state when some of the conditions are satisfied may be less conspicuous than the light emission state when all the conditions are satisfied.

  For example, as a plurality of conditions, “reception of a microwave (radio wave) of a predetermined frequency” (condition 1) and “the received signal level is equal to or higher than a reference value” (condition 2) satisfy two conditions. Then, an alarm is issued based on a predetermined light emission state (for example, red light emission) on the assumption that a radio wave emitted from an alarm target has been received. If only condition 1 is satisfied (the signal level is less than a reference value), Alarm by blue light emission). Even if the distance to the alarm target is long and the received signal level is less than the reference value, it is often the case that the signal level becomes higher than the reference value by further running and approaching the alarm target. In such a case, by giving a warning warning in advance, it is possible to prepare the user's mind so that even if an alarm that satisfies all the conditions is issued, safe driving can be performed without panic.

<Others>
In the above-described embodiment, the LED is described in which the color control is performed by 15 bits in total of 5 bits for R, 5 bits for G, and 5 bits for B. However, the number of bits is not limited to this, and the number of bits is not limited. Is good or small. As the number of bits increases, the number of colors to be controlled increases. For example, if R is 8 bits, G is 8 bits, and B is 8 bits, a total of 24 bits, 16,777,216 colors Color control is possible.

  In the above-described embodiment, the display unit 5 is provided and a map is displayed on the display unit 5. However, the map may not be displayed, or may not be displayed.

  Moreover, although the color LED 22 is built in the case body 11, the present invention is not limited to this, and the color LED 22 may be exposed to the outside. The number of color LEDs installed is arbitrary. In short, it is only necessary that the light emitting unit 21 looks as if it emits one color when viewed from the outside.

  Further, in the embodiment, the position of the light emitting unit 21 is the central part further above the display screen of the display unit 5, but is not limited to this, and is biased to the left or right above the outside of the display screen. The position may be the position, or the outside or the side or the lower side of the display screen.

  In addition, although the light emitting unit 21 is a rectangular region in FIG. 1, the shape thereof is arbitrary, and can take various shapes such as an ellipse, a circle, and the like. As shown in FIG. 6, the light emitting unit 21 may be a predetermined character (character string), symbol, mark, or the like. FIG. 6 illustrates an example in which the light emitting unit 21 is provided on the left side of the display screen 5, and further illustrates an example in which the light emitting unit 21 is configured with a trademark manufacturer name or other logo. And color LED22 is arrange | positioned on the back side (inside the case main body 2) of the light emission part 21 which consists of this logo. In this example, only the logo portion emits light in various colors depending on the situation. For example, the case body 2 is formed of a material that does not transmit light, such as a plastic such as black, and a slit or a hole penetrating inward and outward is provided in a logo portion. Then, a blocking member made of a material (transparent / translucent plastic or the like) through which light passes is fitted and closed. Thereby, the light from the color LED 22 passes through the blocking member to the outside while suppressing dust, dust, and the like from entering the case body 2 through the hole. Therefore, when viewed from the outside, the user looks as if the blocking member, that is, the logo portion, is emitting light.

  Here, only the part such as the logo emits light, but the entire peripheral area including the logo may emit light. For example, a logo or the like is printed on the rectangular light emitting unit 21 shown in FIG. As a result, the entire rectangular area that is the light emitting unit 21 emits light in various colors according to the situation, and the logo rises and is conspicuous by the light.

  7 and 8 show an example of the correspondence relationship between the type of alarm target and the color (LED emission color) associated therewith. As shown in the figure, the alarm target associated with the LED emission color is roughly classified into a radar (corresponding to the “radar wave alarm function” in the embodiment) and wireless (the “radio alarm function” in the embodiment). ), GPS (corresponding to “GPS alarm function” in the embodiment), and system. The system is everything else that does not correspond to any of radar, radio, and GPS, and the emission color is white. Accordingly, when the light is emitted in conjunction with the sound, the control unit 18 performs control for emitting the color LED in white as well as outputting all other sounds not corresponding to the three genres.

  Specific alarm targets belonging to the genre of radar include a normal alarm when a predetermined microwave is received, and a stealth alarm when a stealth wave having a characteristic that a strong radio wave is emitted in an instant is detected. The normal alarm is classified into five levels according to the reception level (signal strength of the received signal). The lowest reception level is “normal alarm level 1” and the emission color is “yellowish green”. As the reception level increases in order, the emission color of “normal alarm level 2” is “yellow”, the emission color of “normal alarm level 3” is “light orange”, and the emission color of “normal alarm level 4” is “orange”. The emission color of “normal alarm level 5” is associated with “red”. In this way, when the reception level is low, a yellow color is used by using a color with a relatively safe image such as green (yellowish green) and raising the level slightly (level 2). It is said. At level 3 or later, the user is warned using a color with an image representing a red-colored danger / warning. Furthermore, the stealth warning is controlled so that the emission color is gradually changed from blue to red, and then the emission color is gradually changed toward blue.

  The relationship between the type of alarm target (alarm item) and emission color in the radio genre is: “Regulatory radio: Pink”, “Car location near: Pink”, “Car location far: Yellow”, “Digital radio: Yellow” , “Outside the car location: light blue”, “Special radio: light blue”, “Station radio: light blue”, “Police wireless: light blue” “Wrecker wireless: light blue”, “Helicopter radio: yellow green”, “Fire fighting helicopter radio” : Yellow-green, Fire-fighting radio: Yellow-green, Emergency radio: Yellow-green, Highway radio: Yellow-green, Security radio: Yellow-green

  The relationship between the type of alarm target (alarm item) and the emission color in the GPS genre is “Orbis: Red”, “Overspeed: Red”, “Limited speed switching: Yellow”, “Regulation area: Yellow” , “Checking area: Yellow”, “Restricted priority area: Yellow”, “Restricted priority area: Yellow”, “High-speed traffic police team: Yellow”, “Intersection monitoring point: Yellow”, “Signal ignore suppression system: Yellow” , “My area: Yellow”, “N system: Blue”, “Traffic monitoring system: Blue”, “Police station: Blue”, “Accident-prone area: Blue”, “Vehicle-prone area: Blue”, “High speed” Steep / continuous curve: Blue, “Highway junction / branch point: Blue”, “ETC lane: Green”, “Service area: Green”, “Parking area: Green”, “Highway oasis: Green”, “High speed” Road Long, continuous tunnel: green ”,“ highway radio Reception area: green "," border: green "," Road Station: Green "," View Point Parking: was green ".
