Description

  The present invention relates to an in-vehicle electronic device such as a radar detector or a car navigation system that includes display means such as a liquid crystal display device and gives predetermined information to a driver of a vehicle.

  2. Description of the Related Art Conventionally, there are in-vehicle electronic devices equipped with a liquid crystal display device that displays various types of information and a voice synthesizer that outputs various types of information as speech. For example, a radar detector, which is an in-vehicle electronic device, detects a microwave emitted from a speed measurement device, or stores the installation position information of the speed measurement device in advance, and uses GPS (Global Positioning System) or the like. When the acquired current position approaches the memorized installation position (when a predetermined approach relationship is reached), the alarm content indicating the approach to the speed measurement device is displayed on the liquid crystal display device using pictures, photographs, characters, etc. In addition to displaying, the content of the alarm is output by voice by the voice synthesizer. For example, an alarm is issued when the detected microwave intensity exceeds a predetermined level, or the first alarm is issued when the current position is within 1000 m from the installation position of the speed measurement device. Further, when the position is within 500 m from the installation position of the speed measuring device, a second alarm is given.

  As a conventional example of a radar detector having these functions, there is one disclosed in Patent Document 1, for example. In the apparatus described in Patent Document 1, as a display mode of an alarm, a target that matches an alarm condition such as a speed measuring device is displayed with a mark, or a distance to the target is displayed with a number.

JP 2009-9546 A

  However, in the conventional vehicle-mounted electronic device, since the display mode of the alarm is common, there has been a problem that the driver of the vehicle cannot be sufficiently alerted. That is, in the conventional in-vehicle electronic device, the mark indicating the target and the number indicating the distance to the target are continuously displayed from the start of the alarm to the cancellation of the alarm, or continuously from, for example, 1000 m and 500 m points. One alarm was displayed. However, in such a general alarm display mode, the same alarm is continuously displayed between the alarm start and the alarm release, so if the driver misses the screen change at the alarm start After that, it is difficult to notice the warning display.

  In addition, the closer the vehicle is to the target, the stronger the driver's attention must be drawn. However, in the conventional general alarm display mode, only the same alarm is continuously displayed from the alarm start to alarm cancellation, so the alarm display mode changes according to the situation that changes every moment. The degree of the driver's attention was always constant, and the alarm display mode was monotonous.

  The present invention has been made in view of the above problems, and an object thereof is to provide an in-vehicle electronic device capable of attracting the driver's attention more strongly than in the past.

  In order to achieve the above object, an in-vehicle electronic device according to the present invention includes (1) an in-vehicle electronic device including a display unit and an alarm unit that displays a predetermined alarm on a screen of the display unit. The alarm means is configured to display a plurality of alarms one after another on the screen in at least a part of the period from the alarm start to the alarm cancellation.

  According to the above configuration, since the display operation of overlapping the alarm displayed later on the already displayed alarm is continuously repeated, the display mode of the series of alarms is dynamic, and the display contents on the screen over time Changes significantly, and a visual effect that strongly attracts the driver's attention can be obtained. Eventually, a large number of alarms will generally occupy the display area on the screen, and the driver's attention will concentrate on the latest updated alarm. As a result, it is possible to alert the driver continuously from the start of the alarm to the cancellation of the alarm. As a result, the monotonousness of the conventional alarm display mode can be eliminated, and the problem that it is difficult to notice the alarm display after the change of the screen is overlooked at the start of the alarm can be solved.

  Here, the “display unit” in the present invention includes, for example, a display capable of displaying information such as an organic ELD (Organic Electroluminescent Display) or a CRT (Cathode Ray Tube) in addition to an LCD (Liquid Crystal Display). Display devices are widely included. The “screen of the display means” refers to a displayable area on the display of the display means.

  The “alarm” in the present invention broadly includes the display on the screen of the display means for alerting the driver, and means both this display itself and a series of display modes in which a plurality of displays are successively stacked. Including. Further, “displaying a plurality of alarms one after another on the screen” means that at least a part of the display area of two or more alarms is displayed in an overlapping manner.

  (2) Preferably, a plurality of different types of predetermined alarm objects are set in the alarm means, and the alarm means includes a plurality of alarm objects on the screen for at least one of the alarm objects. It is preferable that the alarms be displayed one after another.

  According to the above configuration, for example, a plurality of warnings are displayed one after another for one alarm target such as approach to the speed measuring device, so that the driver's attention to this one alarm target can be surely evoked. it can.

  Note that the in-vehicle electronic device of the present invention does not exclude a mode in which different alarms for a plurality of different types of alarm targets are displayed on top of each other, and the alarm means detects a plurality of alarm targets at the same time. In this case, it is possible to adopt a mode in which different alarms for each alarm target are displayed one after the other.

  Here, the “predetermined alarm target” is an object that is set in advance so that the alarm means displays an alarm. For example, a general radar detector has functions such as a GPS alarm function, a radar wave alarm function, and a radio alarm function, and a predetermined alarm target is set for each function. Specific examples of the “predetermined alarm target” will be described in detail in the embodiment of the invention.

  (3) Preferably, the alarm has a display area defined by a contour of a predetermined shape, and the alarm means displays a plurality of alarms on the screen with a time difference, and the alarm already displayed It is preferable that a part of the alarm displayed later is displayed in an overlapping manner.

  According to the above configuration, by defining the alarm display area with a predetermined shape, it is easy to visually recognize the overlap between alarms. For example, the contents of alarms that have already been displayed can be visually recognized by overlapping alarms that are displayed later. Only the contents of the alarm displayed later can be visually recognized. As described above, in the present invention, the content of the alarm is updated by superimposing the alarm displayed later on the already displayed alarm. The already displayed alarm remains on the screen of the display means as it is, and as time passes, the ratio of the plurality of alarms occupying the display area on the screen increases, and the driver's attention is strongly attracted.

  Here, the “display area” of the alarm in the present invention refers to a display area of a single alarm, and the “display area” of the alarm has an area compared to the “display area” of the screen of the display means described above. It can be set small or large. For example, if the alarm “display area” is set smaller than the “display area” area of the screen, the entire or part of the alarm is displayed on the screen. Only a part of is displayed on the screen. When only a part of the alarm is displayed on the screen, the driver is given an impression that the part where the alarm is not displayed is virtually outside the “display area” of the screen. Since it is possible to arouse the desire to know the contents outside the “display area”, it is possible to attract the driver's attention strongly. Moreover, as shown in (4) below, the display areas can be mixed on the screen by changing the areas of the “display areas” of the plurality of alarms.

  (4) Preferably, it is good to set it as the structure which made the outline of all or one part of several said alarms a mutually similar shape.

  According to the above configuration, by using alarms having similar shapes with different sizes, it is possible to elaborate a series of display modes in which a plurality of alarms are successively stacked, and attract the driver's attention. For example, the visual effect of the alarm according to the present invention can be improved by expressing a sense of perspective by overlaying a large alarm on a small alarm, or changing the size of the alarm according to the type of alarm target. .

  Further, for example, the alarms for different types of alarm targets may have different shapes, and the alarm contours for the same type of alarm targets may have similar shapes. According to such a configuration, based on the outline of the alarm, it is possible to determine at a glance the type of the alarm target notified, and a plurality of alarms that overlap one another on the screen are the same type of alarm target. It is possible to easily discriminate which type of alarm object, whether it is for a different type of alarm target.

  (5) Preferably, the alarm may include alarm information including characters, symbols, graphics, still images or moving images, or a combination thereof for notifying the content of the alarm.

  The alarm in the present invention is a display on the screen of a display means for alerting the driver. By including the alarm information, the driver can be notified of the alarm content straight. Furthermore, the present invention is characterized by a series of display modes in which alarms that are displayed later are superimposed on alarms that are already displayed, and alarm information of alarms that have already been displayed is hidden by the alarms that are displayed later. As a result, in order to know the content of the alarm, the driver visually recognizes the alarm with a certain amount of attention, and on the other hand, the driver is interested in knowing the content of the alarm. .

  (6) Preferably, the alarm means displays a plurality of the alarms one after another in a time interval where at least a part of the alarm information is not visible, and then displays one or more alarms. The time may be configured such that all the alarm information is visible.

  According to the above configuration, it is possible to attract a driver's attention or interest strongly by displaying a plurality of warnings one after another at a time interval in which the warning information is not visible. By making it possible, the driver can be made sure of the content of the alarm.

  In other words, by attracting the driver's attention by changing the screen when multiple alarms are displayed one after another, the alarms that are displayed one after another are overlapped, and part of the alarm information is intentionally invisible. This causes the driver to have an active psychological state of wanting to know the content of the alarm information. This is a factor that strongly attracts the driver's attention or interest, and then the driver's attention or interest lasts until all of the alarm information is visible. And the driver | operator who visually recognized alarm information with the active psychological state to want to know for himself will recognize the content reliably. Therefore, when the above-described configuration is adopted, the effect of the alarm that prompts the driver to pay attention is significantly improved as compared with the conventional alarm display mode.

  (7) Preferably, the alarm includes at least the alarm information and a background, and the background has a red color.

  According to the above configuration, it is possible to visually attract the driver's attention by setting the background constituting the alarm to a red color. In particular, the present invention is characterized by a series of display modes in which an alarm that has been displayed is superimposed on an already displayed alarm, and the already displayed alarm remains on the screen of the display means. As a result, the screen of the display means is occupied by a plurality of red alarms as time passes, producing the same visual or psychological effect as the alarm light (alarm light), and increasing the driver's attention. Can be aroused.

  Here, “red color” in the present invention includes red and intermediate colors of red and other colors. For example, “R (red)” and “YR (yellow) classified on the Munsell color system. All colors belonging to “red)” and “RP (red purple)” are included.

  (8) Preferably, a storage unit that stores map information is provided, the display unit displays a map on the screen based on the map information, and the alarm unit includes a period between alarm start and alarm release. It is good to set it as the structure which piles up and displays a plurality of the above-mentioned warnings one after another on at least a part of the period.

  According to the above configuration, in an in-vehicle electronic device such as a radar detector or a car navigation system, the position of an alarm target or the position of a vehicle can be displayed on a map on the screen, and the alarm can be displayed overlaid on the map. it can. As a result, as the display mode in which a plurality of alarms are displayed one after another progresses, a crisis image as if the existing display map is eroded by alarms that multiply one after another on the screen. The warning effect that alerts the driver is greatly improved.

  (9) Preferably, among the plurality of alarms, at least the first alarm displayed may include a moving image that appears to expand from a predetermined point on the screen.

  According to the above configuration, by adopting an unprecedented display operation in which the first warning appears to expand from a predetermined point on the screen, a visual impact is given at the start of the warning and the driver's attention is strengthened. Can be attracted. After that, the display operation of superimposing the subsequently displayed alarm on the already displayed alarm is continuously repeated, and it is possible to continuously alert the driver until the alarm is released. Further, by adopting the above configuration, it is possible to visually convey to the driver the position on the screen where the alarm appears and the relationship between the alarm.

  (10) Preferably, the map is displayed on the screen, and among the plurality of alarms, at least the first alarm to be displayed includes a moving image that appears to expand from a predetermined point on the map; Good.

  According to the above configuration, at the start of an alarm, a visual impact can be given and the driver's attention can be strongly attracted, and the relationship between the predetermined point on the map and the alarm can be visually communicated to the driver. It becomes possible. For example, if a warning about the approach to the speed detection device from a predetermined point on the map appears to expand, the driver recognizes at a glance that the speed detection device is installed at the predetermined point on the map. can do.

  (11) Preferably, the alarm includes a background, and the background is an enlarged map around the predetermined point.

  According to the above configuration, the alarm that appears to expand from a predetermined point on the map not only conveys the position of the alarm target, but the alarm itself includes an enlarged map around the predetermined point. Information can be conveyed to the driver. In addition, the display mode in which the enlarged map appears from a predetermined point on the map is an unprecedented novel display that can strongly attract the driver's attention or interest.

  (12) Preferably, the vehicle includes a position detection unit that detects a position of the vehicle, and a position storage unit that stores position information of a predetermined alarm target. The alarm unit includes the position of the vehicle and the position of the alarm target. Based on the information, it is detected that the vehicle has approached the alarm target up to a predetermined distance, and a plurality of the alarms are successively issued in at least a part of the period from the alarm start based on the approach detection to the alarm cancellation. It is good to make it the structure which overlaps and displays.

  According to the above configuration, for example, in an in-vehicle electronic device having a GPS alarm function such as a radar detector or a car navigation system, in order to notify the approach of the vehicle to the alarm target on the map, The alarm display mode can be applied. As a result, compared with conventional in-vehicle electronic devices, the warning effect that alerts the driver is greatly improved, and the possibility of missing an approach warning to the alarm target Can be greatly reduced.

  (13) Preferably, the warning means may be configured to shorten a time interval when the plurality of warnings are displayed one after another as the distance from the vehicle to the warning target becomes shorter.

  According to the above configuration, as the vehicle approaches the alarm target, the display speed and number of alarms that overlap one after another and the change on the screen increase. As a result, a special visual effect that gives the driver a sense of crisis can be obtained according to the degree of approach to the alarm target, and the driver can be alerted as the vehicle approaches the alarm target. .

  Here, the structure for shortening the time interval when displaying a plurality of alarms one after another is not particularly limited. For example, the time intervals of the alarms displayed one after another may be continuously shortened in conjunction with the distance from the vehicle to the alarm target that changes every moment. In addition, a plurality of predetermined distances to the alarm target that triggers the control process may be set, and each time the vehicle reaches the predetermined distance, the time intervals of the alarms to be displayed one after another are shortened step by step. Good. In this configuration, it is also possible to set only one predetermined distance to the alarm target that triggers the control process. For example, the alarm is started based on the approach detection of the vehicle to the alarm target, and before the vehicle approaches the alarm target to a predetermined distance, a plurality of alarms are displayed one after another at a relatively long time interval, and then When the vehicle approaches the alarm target up to a predetermined distance, a plurality of alarms may be displayed one after another with a relatively short time interval.

  (14) Preferably, the warning means may be configured to display a plurality of the warnings one after another at a time interval according to the speed at which the vehicle approaches the warning target.

  According to the above configuration, as the vehicle rapidly approaches the alarm target, the display speed and number of overlapping alarms and changes on the screen increase. As a result, a special visual effect that gives the driver a sense of crisis can be obtained according to the degree of approach to the alarm target, and the driver can be alerted as the vehicle approaches the alarm target. .

Again, the configuration for shortening the time interval when displaying a plurality of alarms one after another is not particularly limited. For example, in conjunction with acceleration / deceleration of the vehicle, the time intervals of the alarms that are displayed one after another may be continuously shortened. Alternatively, a plurality of predetermined speeds that trigger the control process may be set, and the time intervals of the alarms that are displayed one after another may be shortened step by step each time the vehicle reaches the predetermined speed. In this configuration, it is also possible to set only one predetermined speed to the alarm target that triggers the control process. For example, an alarm is started based on detection of approach of a vehicle to an alarm target, and a plurality of alarms are displayed one after another at relatively long time intervals until a predetermined speed, and then the vehicle reaches a predetermined speed. Then, a plurality of alarms may be displayed one after another with a relatively short time interval. It should be noted that a plurality of predetermined speeds for triggering the control processing are set, and a time interval between alarms to be displayed one after another is gradually increased every time the vehicle falls below the predetermined speed. Good.

  (15) Preferably, the alarm means may be configured to cancel the alarm when the vehicle passes the alarm target and erase all the alarms displayed on the screen.

  According to the above configuration, even if the vehicle is as close as possible to the alarm target and a plurality of alarms occupy the screen of the display means, all alarms on the screen are erased when the alarm target is passed. Return to the display state before the alarm started. As a result, the crisis image formed by displaying multiple warnings one after the other is reversed and the driver is given a psychological state that seems to have been released from the current tension. Can do.

  (16) Preferably, the alarm target is a vehicle speed measuring device. According to such a configuration, for example, in a radar detector having a GPS alarm function, the series of alarm display modes of the present invention is applied to notify the approach of the vehicle to the vehicle speed detection device on the map. can do.

  (17) Preferably, a plurality of different types of predetermined alarm targets are set in the alarm means, and each alarm object is prioritized in accordance with its type, and the alarm means It is preferable that a plurality of the alarms are displayed one after the other on the screen with a higher priority than a predetermined order.

  According to the said structure, the display mode of an alarm can be distinguished according to the priority order of an alarm target, and it becomes possible to call a driver | operator's attention especially about the alarm target with a high priority. That is, for alarm targets with a low priority, a conventional display mode that displays the mark indicating the alarm target and the distance to the alarm target as in the past is used continuously or intermittently, and the driver's attention is generally Arouse. On the other hand, for alarm targets with high priority, the visual effect of attracting the driver's attention can be obtained by adopting the display mode of the present invention in which a plurality of alarms are displayed one after the other on the screen. It is possible to call attention especially. Specific examples of “a plurality of alarm targets” and “priorities” will be described in detail in the embodiments of the present invention.

  (18) Preferably, the in-vehicle electronic device according to (1) to (17) includes a sound output unit, and the alarm unit synchronizes with an alarm sound from the sound output unit in synchronization with a timing of displaying the plurality of alarms. May be configured to output.

  According to the above configuration, an alarm sound is added to the series of display modes of the alarm of the present invention, and an auditory effect that attracts the driver's attention can be further added to the above-described visual effect of the present invention. Here, “timing for displaying a plurality of alarms” includes all timings related to all or part of a series of alarm display modes of the present invention. In addition, the “alarm sound” includes sounds of all aspects such as sound effects, BGM, and voice related to all or part of a series of display forms of the alarm of the present invention.

  For example, an alarm sound such as a sound effect, BGM, or voice may be output before or after the first alarm display or simultaneously with the first alarm display. In any case, the screen can be turned to the driver who has heard the alarm sound, and the alarm displayed on the screen can be surely seen. In addition, a pseudo sound (sound effect) when the second, third,... Alarms appear is output at each display timing, or a sound effect such as a siren or BGM continuously from the alarm start to the alarm release. Can also be output.

  As described above, according to the present invention, it is possible to provide an in-vehicle electronic device that can attract the driver's attention more strongly than in the past.

Further, on the left side of the rear surface of the housing 11 in the drawing, a through hole 18 through which sound output from a speaker 17 as sound output means is transmitted to the outside and an insertion hole 19 for a DC power jack are formed. In addition, although illustration is abbreviate | omitted, in this embodiment, the power supply of the main body side of the radar detection apparatus 10 is acquired from a cigar socket (namely, secondary battery which is a battery of a vehicle). Further, a microwave receiver 22 and a wireless receiver 23 are built in the center of the back surface of the housing 11.

  A slot 20 for inserting a memory card 25 as a storage medium into the memory card reader 24 is formed on the left side surface of the housing 11 shown in FIG. The memory card reader 24 can take in data stored in the memory card 25 and write the contents of the memory of the database 27 and the control unit 26 into the memory card 25. More specifically, if the data stored in the memory card 25 includes update information about new alarm target information (position information including longitude / latitude, type information, etc.), the update information is sent to the control unit 26. Is stored (downloaded) in the database 27 built in the apparatus, and the data in the database 27 is updated.

  The database 27 is a nonvolatile memory (for example, EEPROM) in the microcomputer of the control unit 26 or externally attached to the microcomputer. In the database 27, information related to a certain alarm target is registered at the time of shipment, and information on a new alarm target added after that can be updated as described above.

  The wireless receiver 23 receives incoming radio waves having a predetermined frequency. The infrared light receiving unit 15 performs data communication with a remote controller (portable device: slave device) 28 by infrared rays and performs various settings for the apparatus. The remote controller 28 includes a standby switch button, a first setting button, a second setting button, a selection button, a cancel button, a determination button, and up / down / left / right cross buttons (not shown).

  The control unit 26 is a microcomputer including a CPU, a ROM, a RAM, a nonvolatile memory, an I / O, and the like. The control unit 26 executes predetermined processing based on information input from the various input devices, and outputs an output device. Use it to output predetermined alarms, messages and information. Note that these basic configurations can be basically the same as the conventional ones.

  The functions of the radar detector of the present embodiment are stored as a program on the EEPROM of the control unit 26 and are implemented by the CPU of the control unit 26 executing this program. Functions executed by the CPU according to the program include a GPS log function, a standby screen display function, a radar scope display function, a GPS alarm function, a radar wave alarm function, a wireless alarm function, and the like. It is embodied as a function of the CPU.

  The GPS log function is a function in which the control unit 26 stores the current position detected by the GPS receiver 21 every second in association with the detected time and speed (vehicle speed) in a nonvolatile memory as a position history. This location history is a function of recording in, for example, the NMEA (National Marine Electronics Association) format.

  The standby screen display function is a function for displaying the speed 141, latitude 142, and longitude 143 of the host vehicle detected by the GPS receiver 21 on the display unit 14, as shown in FIG.

  Here, the screen display area 140 of the display unit 14 when the standby screen display function, the GPS alarm function, the radar wave alarm function, and the wireless alarm function are executed is divided into a main display area 140A and an icon display area 140B.

On the other hand, a azimuth magnetic needle icon 144, a road selection icon 145, a radar reception sensitivity mode icon 146, and a mode selection icon 147 are displayed in the icon display area 140B. Further, the current time 148 is displayed at the right end of the icon display area 140B in the figure.

  As shown in FIG. 3 (b), the radar scope display function is configured to store alarm targets within a predetermined range (for example, within a range of about 1 km) from the current position detected by the GPS receiver 21 in the database 27. This is a function of searching based on information and displaying the relative positional relationship between the host vehicle and the alarm target on the display unit 14.

  During execution of the radar scope display function, a map 151 based on the map information stored in the database 27 is displayed in the main display area 140A, and an arrow-shaped own vehicle icon 152 indicating the position of the own vehicle is displayed on the map 151. indicate. Further, when an event occurs during execution of the radar scope display function (when a predetermined condition for alerting is met), “L”, “RD”, “P”, “N” are displayed on the map 151. An alarm target icon 153 having characters such as “” is displayed to indicate the type and position of the alarm target. Further, during execution of the radar scope display function, the legal speed 154 of the road on which the host vehicle is traveling and the current speed 155 of the host vehicle are displayed in the lower right of the main display area 140A in the figure.

  If the pressing of the standby switching button provided on the remote controller 17 is detected during the execution of the standby screen display function shown in FIG. 3A, the control unit 26 switches to the radar scope display function shown in FIG. Further, when pressing of the standby switch button provided on the remote controller 17 is detected during execution of the radar scope display function, processing for switching to the standby screen display function is performed.

  The GPS alarm function is a process executed at a predetermined time interval (1 second interval) by an event from a timer included in the control unit 26, and is detected by the latitude and longitude of the alarm target stored in the database 27 and the GPS receiver 21. Based on the current latitude and longitude of the host vehicle, the distance between the two is calculated, and when the calculated distance reaches a predetermined approach distance (for example, within 2 km), an alarm (for example, FIG. 8) is displayed. (See reference numeral 30 in (a)), and a warning sound such as a sound effect, BGM, or voice is output from the speaker 17.

  Examples of the alarm target of the GPS alarm function include a speed measuring device (loop coil, LH system, H system, radar-type orvis, etc.), mouse catching area, moving orvis area, tracking type control area, temporary stop control area, intersection control Area, other control area, seat belt inspection area, drinking inspection area, mobile phone inspection area, other inspection area, intersection monitoring point, signal ignore suppression system, expressway traffic police corps, N system, traffic monitoring system, police station, accident There are many areas, service areas, parking areas, highway oasis, highway length / continuous tunnels, highway radio reception areas, road stations, viewpoint parking, parking lots, public toilets, etc. Latitude / longitude information indicating A schematic view or photograph data displayed on the 4, stored in the database 27 in association with the voice data.

  The radar wave alarm function displays an alarm on the display unit 14 and an alarm sound from the speaker 17 when a radio wave corresponding to a microwave of a predetermined frequency band emitted from the speed measuring device is detected by the microwave receiver 22. Is an alarm function that outputs. For example, when a microwave of a predetermined frequency band emitted from the speed measuring device is detected by the microwave receiver 22, a schematic diagram or a photograph of a radar stored in the database 27 is displayed on the display unit 14 as an alarm. Then, the voice data stored in the database 27 is read out and a voice “Radar. Speed attention” is output from the speaker 17.

  The wireless alarm function is a function for issuing an alarm so that the wireless receiver 23 does not interfere with traveling or the like when a radio wave emitted by an emergency vehicle or the like is received. In the radio alarm function, the control radio, car radio, digital radio, special radio, police radio, police phone, police activity radio, wrecker radio, heli tele radio, fire helicopter radio, fire fight radio, emergency radio, expressway radio When a radio frequency is scanned at the scanned frequency and a radio frequency is received, a schematic diagram indicating that the radio frequency corresponding to the frequency stored in the database 27 for each radio type is received is used as an alarm screen. While being displayed on the display unit 14, voice data stored in the database 27 for each wireless type is read out, and an alarm sound indicating the wireless type is output from the speaker 17. For example, when a control radio is received, a voice is output like “control radio. Speed attention”.

  Here, the radar scope display function, the GPS alarm function, the radar wave alarm function, and the radio alarm function are set with a plurality of different types of alarm targets as described above, and the priority order according to the type of each alarm target Is defined. The priority order of each alarm target is, for example, that the color of the alarm target icon 153 shown in FIG. 3B is color-coded into “red”, “yellow”, “blue” or “green” groups in descending order of priority. It is visualized with. For example, for the alarm target belonging to the “red” group with the highest priority, the alarm is notified in a characteristic display mode of the present embodiment described below, and the “yellow” with the second lowest priority is displayed. "," Blue "or" green ", alarms are notified in the same general display mode (not shown) as before.

<Alarm display mode for in-vehicle electronic devices>
Next, an alarm display mode that is a feature of the in-vehicle electronic device will be described in detail with reference to FIGS.

  In the embodiment described below, the GPS alarm function during execution of the radar scope display function described above is taken as an example, and alarm objects with high priority to which the display mode of this alarm is applied are a loop coil, an LH system, A speed measuring device such as H system or radar type Orvis. The control unit 26 shown in FIG. 2 stores the latitude / longitude of the speed measuring device (see, for example, the reference numeral 153 in FIG. 3B) stored in the database 27 and the current latitude of the host vehicle detected by the GPS receiver 21. Based on the longitude (see, for example, reference numeral 152 in FIG. 3B), the distance between the two is calculated, and when the calculated distance reaches a predetermined approach distance, an alarm configured as described below is issued. Information is displayed on the screen 14 in a display manner described below.

<< Alarm configuration itself >>
First, a specific example of an alarm according to the present embodiment will be described with reference to FIGS. In these drawings, the alarm 30 has a display area defined by a contour 32 having a predetermined shape, and alarm information 33 for informing the contents of the alarm 30 is included in the display area.

  The display area of the alarm 30 may be, for example, a background 31 colored in a predetermined color as shown in FIG. 5A, and preferably the background 31 is a red color and the driver is imaged of urgency. It is good to do so. Moreover, as shown in the figure (b), the background 31 may display the schematic diagram or photograph of the speed measuring device which is a warning object. Furthermore, as shown in FIG. 5C, the background 31 may be an enlarged map around the point where the speed measuring device is installed. As described above, the schematic diagram, photograph, or enlarged map of the speed measuring device included in the background 31 serves as alarm information 33 for informing the contents of the alarm 30.

  The alarm information 33 is composed of characters, symbols, figures, still images or moving images, or a combination thereof for informing the content of the alarm 30. For example, as shown in FIGS. Characters such as “alarm”, “loop coil”, and “2 km” are displayed, indicating that these displays are alarms, the type of speed measuring device that is the target of alarm, and the distance from the vehicle to the speed measuring device. Inform.

  The background 31 of the alarm 30 described above includes, for example, a flat two-dimensional computer graphics as shown in FIG. 4A, a shadow 31a and a thickness 32a in the two-dimensional computer graphics as shown in FIG. In addition, a three-dimensional drawing may be used. Further, as shown in FIG. 5B, the entire alarm 30 may be three-dimensional computer graphics. Here, “computer graphics” broadly includes visual information created using a computer or processed by a computer.

  Furthermore, the alarm 30 may be either transparent or non-transparent, and as shown in FIG. 5C, the background 31 (and alarm information 33) of the alarm 30 may be drawn as a transparent body such as glass. As shown in FIGS. 4A and 4B, when the alarm 30 is made non-transparent, the contents of the alarm 30 that has already been displayed cannot be seen because the alarm 30 that is displayed later overlaps, and the alarm that is displayed later Only 30 contents are visible. On the other hand, when the alarm 30 is transparent, the content of the alarm 30 displayed before can be visually recognized through the alarm 30 displayed later.

  As shown in FIG. 6, the outlines 32 of the plurality of alarms 30, 30, 30,... May be similar to each other. By using the alarms 30 having similar shapes of different sizes, it is possible to elaborate a series of display modes in which a plurality of alarms 30, 30, 30. For example, a perspective can be expressed by overlapping a large alarm 30 on a small alarm 30, or the size of the alarm 30 can be changed according to the type of alarm target such as a loop coil, LH system, H system, radar type orvis, etc. Thus, the visual effect of the alarm 30 in the present embodiment can be improved.

  Further, the size of the display area of the alarm 30 is not particularly limited, and the area may be set smaller or larger than the display area 140 of the screen 14 shown in FIG. Is possible. For example, as shown in FIG. 7, the display areas of the plurality of alarms 30 </ b> A to 30 </ b> C can be made different in size and mixed on the screen 14. When the display area is set smaller than the area of the display area 140 of the screen 14 as in the alarms 30A and 30B, the entire or part of the alarms 30A and 30B is displayed on the screen 14, When the vertical width or horizontal width of the display area is larger than the vertical width or horizontal width of the display area 140 of the screen 14 as in the alarm 30C shown in the figure, only a part of the alarm 30C is displayed on the screen 14. It becomes the mode to do. Although illustration is omitted, even when the alarm display area is set larger than the area of the display area 140 of the screen 14, only a part of the alarm is displayed on the screen 14. As described above, when only a part of the alarms 30A to 30C or the like is displayed on the screen 14, the part that is not displayed such as the alarms 30A to 30C is virtually outside the display area 140 of the screen 14. This makes it possible to give the driver a strong impression and to urge the driver to know the contents outside the display area 140, thereby attracting the driver's attention strongly.

<<< Action and effect >>>
By defining the display area of the alarm 30 with the contour 32 having a predetermined shape, the overlapping of the alarms 30 can be easily seen. For example, as shown in FIGS. 5 (a), 5 (b) and 6, the alarm 30 has already been displayed. The contents of the alarm 30 are not visible due to overlapping of the alarms 30 displayed later, and only the contents of the alarm 30 displayed later can be visually recognized. Thus, in this embodiment, the content of the alarm 30 is updated by superimposing the alarm 30 displayed later on the alarm 30 already displayed. The alarm 30 that has already been displayed remains on the screen 14 as it is, and the proportion of the plurality of alarms 30, 30, 30... Will attract.

  Further, the alarm 30 in the present embodiment is a display on the screen 14 for prompting the driver to pay attention. By including various types of alarm information 33, the driver can be informed of the contents of the alarm 30 straight. . Further, since the alarm information 33 of the already displayed alarm 30 is hidden by the alarm 30 displayed later, the driver must visually recognize the alarm 30 with a certain degree of caution in order to know the contents of the alarm 30. On the other hand, the driver is also interested in knowing the contents of the alarm 30.

  Further, by using alarms 30, 30, 30... Having similar shapes with different sizes as shown in FIG. 6, a series of display modes in which a plurality of alarms 30 are successively stacked are elaborated, and the driver's attention is given. It becomes possible to attract. For example, the visual effect of the alarm 30 in the present embodiment can be obtained by expressing perspective by overlapping the large alarm 30 on the small alarm 30 or changing the size of the alarm 30 according to the type of the alarm target. Can be improved.

<< Display mode of a series of alarms >>
Next, a series of alarm display modes according to the present embodiment will be described with reference to FIGS. FIGS. 8A to 8C and FIGS. 9A and 9B are diagrams showing a display mode of a series of alarms according to the present embodiment. FIGS. 10A to 10C are diagrams illustrating an example of a countdown alarm displayed at the end of a series of alarm display modes. FIG. 15 is a flowchart showing a flow of control processing of a series of alarm display modes. Furthermore, in the following description of the control processing, the reference numerals in FIG.

  In step S <b> 1 of FIG. 15, first, the control unit 26 detects the latitude and longitude of the alarm target having the high priority described above among the alarm targets stored in the database 27 and the current host vehicle detected by the GPS receiver 21. Based on the latitude and longitude, it is determined whether or not the host vehicle has approached the alarm target up to a predetermined distance (for example, 3 km). When the control unit 26 determines that it has not approached the predetermined distance (NO), the control process shown in FIG. 15 is terminated. On the other hand, if it is determined that the control unit 26 has approached the predetermined distance (YES), the process proceeds to step S2, and the first alarm 30 is displayed on the screen 14 shown in FIG. A sound effect (alarm sound) 17a is output.

  Subsequently, it progresses to step S3 and the control part 26 judges whether the own vehicle reached | attained 2 km point to the warning object. When it is determined that the control unit 26 has not reached the 2 km point (NO), the process proceeds to step S4, and the time interval of 20 seconds after the display of the previous alarm 30 (the time interval of the sound effect 17a is also the same). The same shall apply hereinafter), and the next alarm 30 is displayed over the previous alarm 30. Thereafter, the determination in step S3 is repeated.

  On the other hand, if it is determined in step S3 that the control unit 26 has reached the 2 km point (YES), the process proceeds to step S5, and the time interval for displaying the alarms 30 one after another is displayed as 20 seconds, 15 seconds, 10 seconds. And stepwise acceleration (see FIG. 8B). For example, when the control process of step S5 is executed for the first time, the alarm 30 is given at a time interval of 20 seconds, when the control process of step S5 is executed for the second time, 15 seconds, and when step S5 is executed for the third time, the alarm 30 is given every 10 seconds. Are displayed one after another, and thereafter, the alarm 30 is displayed one after another while maintaining an interval of 10 seconds until the point of 1 km is reached to the alarm target (YES in step S6). In step S5, instead of accelerating the time intervals for displaying the alarms 30 one after another, the time intervals may be continuously accelerated to 20 seconds, 19 seconds, 18 seconds,... 10 seconds.

  Subsequently, it progresses to step S6 and the control part 26 judges whether the own vehicle reached | attained 1 km point to the warning object. When it is determined that the control unit 26 has not reached the 1 km point (NO), the determination in step S5 is repeated. On the other hand, when it is determined that the control unit 26 has reached the 1 km point (YES), the process proceeds to step S7, and the time interval for displaying the alarms 30 one after another is shortened to 5 seconds (see FIG. 8C). ).

  Subsequently, it progresses to step S8 and the control part 26 judges whether the own vehicle reached | attained the 500 m point to alarm object. If the control unit 26 determines that the 500 m point has not been reached (NO), the process returns to step S7, and the alarms 30 are displayed one after another while maintaining a time interval of 5 seconds. On the other hand, if it is determined that the control unit 26 has reached the 500 m point (YES), the process proceeds to step S9, and the control unit 26 shortens the time interval for displaying the alarms 30 one after another to 0.5 seconds. (See FIGS. 9A and 9B).

  When the own vehicle reaches the point of 500m to the alarm target (steps S10 and S11), the alarms 30 are displayed one after another at an extremely short time interval of 0.5 seconds. ), The content of the screen 14 changes in a busy manner, and the existing map 151 has a crisis image as if it is eroded by the alarm 30 that is successively propagated on the screen 14. Form. At this time, the sound effect 17a output from the speaker 17 is changed to a continuous sound of “pea” in accordance with the alarm 30 displayed at an extremely short time interval, and the driver no longer has alarm information 33 of the alarm 30 that changes rapidly. Cannot be accurately recognized.

  Subsequently, it progresses to step S10 and the control part 26 judges whether the own vehicle reached | attained the 300-m point to alarm object. If the control unit 26 determines that the 300m point has not been reached (NO), the process returns to step S9, and the alarms 30 are displayed one after another while maintaining the time interval of 0.5 seconds. On the other hand, if it is determined that the control unit 26 has reached the 300 m point (YES), the process proceeds to step S11, and the countdown alarm 40 shown in FIGS. 10 (a) to 10 (c) is displayed before the alarm 30.

  When the host vehicle reaches the 300 m point to the alarm target (steps S10 and S11), it is a situation that is not in time unless the speed of the host vehicle is decelerated immediately, and the countdown shown in FIGS. The alarm 40 notifies the time limit until reaching the alarm target, such as “10 seconds to the loop coil”, “5 seconds to the loop coil”, and “1 second to the loop coil”. The number of seconds displayed by the countdown alarm 40 is calculated based on the current speed and position of the host vehicle acquired from the GPS receiver 21 and the position of the alarm target stored in the database 27. At this time, behind the countdown alarm 40 on the screen 14, the alarms 30 are displayed one after the other at a time interval of 0.5 seconds continuously from the 500 m point, and the sound effect 17a of “Peep” is output. .

  Thereafter, the process proceeds to step S12, where the control unit 26 compares the current position of the host vehicle acquired from the GPS receiver 21 with the position of the alarm target stored in the database 27, and the host vehicle has passed the alarm target. Determine whether or not. When the control unit 26 determines that the alarm target has not been passed (NO), the process returns to step S11 and the display of the countdown alarm 40 is maintained. On the other hand, if the control unit 26 determines that the alarm target has been passed (YES), the process proceeds to step S13, where all the alarms 30 and the countdown alarm 40 on the screen 14 are erased, and a series of alarms according to the present embodiment. The control process related to the display mode is terminated. As a result, the screen 14 returns to the standby state shown in FIG.

<<< Action and effect >>>
In the above-described vehicle-mounted electronic device of the present embodiment, the display operation of overlapping the alarm 30 that is displayed later on the alarm 30 that has already been displayed is continuously repeated, so the display mode of the series of alarms 30 is dynamic. The display contents on the screen 14 change greatly with time, and a visual effect that strongly attracts the driver's attention can be obtained. Eventually, a large number of alarms 30, 30, 30... Generally occupy the display area on the screen 14, and the driver's attention is concentrated on the latest updated alarm 30. As a result, it is possible to alert the driver continuously from the start of the alarm to the cancellation of the alarm. As a result, the monotonousness of the conventional alarm display mode can be eliminated, and the problem that it is difficult to notice the alarm display after the change of the screen is overlooked at the start of the alarm can be solved.

  For example, since a plurality of alarms 30, 30, 30... Are displayed one after another for one alarm object such as approach to a loop coil, the driver's attention to this one alarm object can be reliably evoked. . Further, as the vehicle approaches the alarm target, the display speed and number of the alarms 30 that overlap one after another and the change on the screen 14 increase. As a result, a special visual effect that gives the driver a sense of crisis can be obtained according to the degree of approach to the alarm target, and the driver can be alerted as the vehicle approaches the alarm target. .

  Furthermore, even if the vehicle approaches the alarm target as much as possible, and a plurality of alarms 30 (including the countdown alarm 40) are in a state of almost occupying the screen 14, all alarms on the screen 14 are passed when the alarm target is passed. 30 is deleted, and the standby state before the alarm starts is restored. As a result, the crisis image formed by displaying a plurality of alarms 30 one after the other is reversed and the driver is given a psychological state as if he had been released from the tension he had so far. be able to.

  In addition to this, it is possible to distinguish the display mode of the alarm according to the priority order of the alarm target, and the driver's attention should be paid to the alarm target with high priority such as loop coil, LH system, H system, radar type orvis, etc. It can be aroused. In other words, for alarm targets with a low priority, such as a control area, an inspection area, a parking area, etc., a general display mode for continuously or intermittently displaying a conventional mark indicating the alarm target and the distance to the alarm target And generally alert the driver. On the other hand, for alarm targets with high priority, such as a speed measurement device, the display mode of the present embodiment in which a plurality of alarms 30 are displayed one after the other on the screen 14, thereby attracting the driver's attention. Effects can be obtained, and the driver's attention can be particularly raised.

  As described above, for example, in a vehicle-mounted electronic device having a GPS alarm function such as a radar detector or a car navigation system, a series of the present embodiment is used to notify the approach of the vehicle to the alarm target on the map 151. The display mode of the alarm 30 can be applied, and as a result, the effect of the alarm for alerting the driver is significantly improved as compared with the conventional on-vehicle electronic device, and the approach alarm to the alarm target is overlooked. The possibility can be greatly reduced.

<< About the display area on the screen that displays the alarm >>
Here, in the above-described embodiments of FIGS. 8 to 10, an example in which a plurality of alarms 30, 30, 30... Are displayed one after another in the main display area 140 </ b> A of the screen 14 is illustrated. The display mode of the alarm is not limited to this. For example, as shown in FIG. 11, using all the display areas 140 on the screen 14, a plurality of alarms 30, 30, 30,... May be displayed in a manner that extends from the main display area 140A to the icon display area 140B. .

  For example, for the above-described high priority alarm target, a plurality of alarms 30, 30, 30... Are changed from the main display area 140A to the icon display area 140B using all the display areas 140 of the screen 14 shown in FIG. It is good to use a display mode in which a plurality of alarms 30, 30, 30,... Do not protrude from the main display area 140A, as in FIGS. .

<< About the outline of the alarm >>
As shown in FIGS. 12A to 12C, the contours 32 and 52 of the alarms 30 and 50 may have different shapes depending on the type of the alarm target. For example, the outline 32 of the alarm 30 that notifies the approach to the loop coil is a square, and the outline 52 of the alarm 50 that notifies the approach to the H system is a circle. By adopting such a configuration, it is possible to determine at a glance the type of the alarm target notified based on the contours 32 and 52 of the alarms 30 and 50, and a plurality of alarms that overlap one after another on the screen 14 It is possible to easily discriminate which type of alarm object 30 or 50 is for the same type of alarm target, different alarm type or not.

<< About the appearance of warnings >>
Preferably, as shown in FIGS. 13A to 13C, a moving image that appears so that the alarm 60 expands from a predetermined point on the screen 14 may be included. As an example, first, a predetermined point on the map 151 shown in FIG. 13A, for example, a red dot 60 ′ blinking at the position of the loop coil stored in the database 27 (see FIG. 2) is displayed for a very short time. . Next, as shown in FIG. 13B, a rectangular outline 60 ″ that rapidly expands from the point where the red dot 60 ′ on the map 151 blinks is displayed. In the region surrounded by the rectangular outline 60 ″ The display contents gradually become clear during the enlargement process, and finally a square alarm 60 as shown in FIG. 13C appears on the map 151. In the present embodiment, the alarm 60 is an enlarged map around the point indicated by the red dot 60 ′ in FIG.

  Next, as shown in FIG. 14A, when the host vehicle further approaches the loop coil, a rectangular outline 60 ″ rapidly expands from the map 151, and the next alarm 60 appears. A plurality of alarms 60, 60, 60... Appear one after another and overlap on the screen 14.

  Further, in FIG. 14A, when approaching a new alarm target other than the loop coil, for example, a radar type orbit stored in the database 27 (see FIG. 2), the radar type orbit on the map 151 is displayed. A new red dot 70 'flashes at the position of. Next, as shown in FIG. 14B, a circular outline 70 ″ that rapidly expands from the point where the red dot 70 ′ on the map 151 blinks is displayed. Also in the enclosed area, the display content gradually becomes clear as it is enlarged, and finally a circular alarm 70 as shown in FIG. 14C appears on the map 151. The alarm 70 of the present embodiment is a schematic diagram or a photograph showing a radar type orvis.

  In this way, a plurality of different alarms 60, 60, 60... And 70, 70, 70... Appear one after another and overlap on the screen 14, but the driver is based on different contour shapes. Thus, the alarms 60 and 70 can be distinguished at a glance.

  As described above, in the case of including an animation in which the alarms 60 and 70 appear so as to expand from a predetermined point on the screen 14, when the alarms 60 and 70 appear, a visual impact is given to the driver. Attention can be strongly attracted, and the relationship between the predetermined points on the map 151 and the alarms 60 and 70 can be visually communicated to the driver. As a result, the driver can recognize at a glance that the loop coil or the radar-type orvis is installed at a predetermined point on the map 151.

<< About the control process of the time interval to display the alarm >>
In the control processing illustrated in FIG. 15, the distance to the alarm target is set in advance as “2 km”, “1 km”, “500 m”, and “300 m”, and when the own vehicle has reached these distances, The time interval when displaying the alarms 30 in succession one after another was shortened. However, the control process for shortening the time interval of the alarm 30 is not limited to FIG.

  For example, it is possible to set only one distance to the alarm target that triggers the control process. After the own vehicle approaches the alarm target up to 3 km and starts the alarm according to the present embodiment, a plurality of alarms are successively issued at relatively long time intervals while the distance between the own vehicle and the alarm target exceeds “1 km”. Then, when the distance between the host vehicle and the alarm target reaches “1 km”, a plurality of alarms 30 may be displayed one after the other at relatively short time intervals. Also, without setting the distance to the alarm target that triggers the control process, the time intervals of the alarms 30 that are displayed one after another are continuously linked in conjunction with the distance from the own vehicle to the alarm target that changes every moment. It is good also as a structure shortened.

  Furthermore, it is also possible to display a plurality of alarms 30 one after another at a time interval corresponding to the speed at which the host vehicle approaches the alarm target. In the case of such a control process, the display speed, the number, and changes on the screen of the alarms 30 that overlap one after another increase as the host vehicle approaches the alarm target rapidly. As a result, a special visual effect that gives the driver a sense of crisis is obtained according to the degree of approach to the alarm target, and the driver's attention can be raised as the host vehicle approaches the alarm target. Become.

  As a method of control processing according to the speed of the host vehicle, for example, the time intervals of the alarms 30 that are displayed one after another may be continuously shortened in conjunction with acceleration / deceleration of the host vehicle. Alternatively, a plurality of predetermined speeds that trigger the control process may be set, and the time intervals of the alarms 30 that are displayed one after another each time the host vehicle reaches the predetermined speed may be shortened step by step. In this case, it is also possible to set only one predetermined speed to the alarm target that triggers the control process. For example, when the host vehicle is traveling at “50 km / h” or less, a plurality of alarms 30 are displayed one after the other at relatively long time intervals, and then when the host vehicle exceeds “50 km / h”, A plurality of alarms 30 may be displayed one after another at short time intervals. It should be noted that a plurality of predetermined speeds that trigger the control process are set, and the time interval of the alarms 30 to be displayed one after another is gradually increased each time the vehicle becomes lower than the predetermined speed. Also good. Further, even when an approach to a high priority alarm target is detected, if the speed of the host vehicle at that time is equal to or lower than the speed limit, the control process shown in FIG. An alarm may be displayed in the manner described above.
