Description

  The present invention relates to an in-vehicle electronic device and a program that provide eco-drive information.

  There is known an in-vehicle electronic device that evaluates how eco-friendly a driver has driven (eco-drive evaluation) according to the user's efforts and displays the evaluation content in characters (Patent Document 1).

Japanese Patent Laid-Open No. 2005-016443

  However, in such an in-vehicle electronic device, since the driver is concentrated on driving, the driver rarely sees the display of evaluation contents, and the driver cannot be naturally conscious about eco-driving. There was a problem.

  Further, if the evaluation contents are displayed in characters, the driver needs to read the characters, and there is a problem that it is difficult to acquire a driving operation that becomes an eco-drive sensuously and intuitively.

  Therefore, the present invention has been made to solve such a problem, and can make the driver aware of eco-driving more naturally than before, and driving operation to become eco-driving is sensual and intuitive. It is an object of the present invention to provide an in-vehicle electronic device and a program that can be acquired.

In order to achieve the above-described object, an in-vehicle electronic device according to the present invention includes: (a) a drive state detecting unit that detects a drive state in an in-vehicle electronic device that displays a predetermined event occurrence screen when a predetermined event occurs; Standby screen display means for displaying eco-drive information based on the drive status detected by the drive status detection means as a standby screen which is a screen to be displayed at least when the event occurrence screen is not displayed, and the drive status Engine speed detection means for detecting engine speed and vehicle speed detection means for detecting vehicle speed are provided as detection means, and the standby screen display means has a predetermined vehicle speed detected by the vehicle speed detection means. If it is less than the speed, the engine speed detected by the engine speed detecting means is detected. The eco-drive information is displayed based on the gin rotation speed, and when the vehicle speed detected by the vehicle speed detection means is equal to or higher than a predetermined speed, the eco-drive information is displayed based on the vehicle speed detected by the vehicle speed detection means. It is characterized by displaying eco-drive information.
(B) The engine speed detecting means may detect a change in the engine speed based on the superimposed power supply noise.
(C) The standby screen display means may display the ratio between the speed and the engine speed as the eco-drive information.
(D) It is preferable that the drive state detection unit includes a vibration detection unit that detects a vibration of the vehicle, and the standby screen display unit displays the eco-drive information based on the vibration state detected by the vibration detection unit.
(E) In a vehicle-mounted electronic device that displays a predetermined event occurrence screen when a predetermined event occurs, a drive state detection unit that detects a drive state, and a standby screen that is a screen displayed at least when the event occurrence screen is not displayed A standby screen display means for displaying eco-drive information based on the drive state detected by the drive state detection means, and a vibration detection means for detecting vehicle vibration as the drive state detection means and a vehicle speed detection And a standby screen display means, when the vehicle speed detected by the vehicle speed detection means is less than a predetermined speed, based on the vibration state detected by the vibration detection means. A vehicle that displays eco-drive information and is detected by the vehicle speed detecting means If the speed is higher than the predetermined speed may be displayed the eco-driving information on the basis of the speed of the vehicle detected by said vehicle speed detecting means.
(F) In a vehicle-mounted electronic device that displays a predetermined event occurrence screen when a predetermined event occurs, a drive state detection unit that detects a drive state, and a standby screen that is displayed at least when the event occurrence screen is not displayed A standby screen display means for displaying eco-drive information based on the drive state detected by the drive state detection means, and a vibration detection means for detecting vehicle vibration as the drive state detection means, and the standby screen The display means may display the eco-drive information based on the vibration state detected by the vibration detection means.
(G) On the premise of (d) to (f) above, the standby screen display means may display the eco-drive information based on the engine speed obtained from the vibration state detected by the vibration detection means.
(H) The program of this invention is realizable as a program for making a computer implement | achieve the function as each means in the vehicle-mounted electronic device as described in any of (a)-(g).
Each of the above inventions may be the inventions described in the following (8) and (9). Moreover, there exist the following as an in-vehicle electronic device relevant to this invention.
(1) In the in-vehicle electronic device that displays a predetermined event occurrence screen when a predetermined event occurs, the vehicle-mounted electronic device includes a standby screen display unit that displays a standby screen that is a screen that is displayed at least when the event occurrence screen is not displayed. The standby screen display means displays eco-drive information.

As the eco-drive information, for example, advice on eco-drive or the like may be simply displayed (drawn). For example, "Do you check the tire pressure?""Is there any unnecessary luggage left on the trunk?""The drive can save fuel if you make a plan" To promote eco-driving.
Examples of the predetermined event include a radar approach warning in a radar detector. Moreover, for example, intersection guidance in a navigation device can be mentioned.

  For example, a graph display screen, which will be described later, is usually displayed as a standby screen of a radar detector, and a target POI (position information: Point Of Interest) such as an orvis approached at the time of radar wave reception warning or at a predetermined distance When a predetermined event such as a time occurs, it may be automatically switched to a predetermined event occurrence screen such as an alarm screen or a radar scope screen.

  In this way, information about the event can be obtained when the event occurs, while eco-driving information is displayed in the standby state where no event has occurred, so that eco-driving can be conscious on a daily basis. . In particular, since the event occurrence screen is often noticed by the user, there are many cases where attention is paid to the contents of the standby screen naturally even when switching from the event occurrence screen to the standby screen. Therefore, it is possible to deeply impress the contents of the standby screen, that is, eco-drive information, by using the attention to the event occurrence screen. Therefore, it is possible to make the driver aware of eco-driving more naturally than before. In particular, it is preferable to output a sound (for example, an alarm sound corresponding to the event) until the display of the event occurrence screen is ended, and to end the output of the alarm sound when switching to the standby screen displaying the eco-drive information. . In this way, the driver can be easily made aware of eco-driving.

(2) Drive status detection means for detecting a drive status is provided, and the standby screen display means may display eco-drive information based on the drive status detected by the drive status detection means. For example, the eco-drive information is particularly preferably changed in content based on the drive state detected by the drive state detection means.

  (3) For example, the drive state detection means includes vehicle speed detection means for detecting the vehicle speed, and the eco-drive information is detected by the vehicle speed detection means as a first axis for a time axis and a second axis. It is preferable to include a graph showing the vehicle speed.

  (4) Further, for example, the drive state detection means includes vehicle acceleration detection means for detecting vehicle acceleration, and the eco-drive information includes a first axis as a time axis and a second axis as the vehicle acceleration detection means. It is preferable to include a graph showing the detected vehicle speed.

If it carries out like said (3) and (4), the state and change of speed and acceleration will be understood only by seeing a graph. For example, a bar graph (or line graph) with the horizontal axis as the time axis and the vertical axis as the speed is displayed on the liquid crystal screen. The flatter the graph, the better the fuel economy. On the other hand, if you start suddenly, accelerate, brake, etc., a graph will appear. In addition, when sudden start, sudden acceleration, sudden braking, etc. are repeated, the graph is displayed so as to wave.
This display unit is installed at a position where the driver can see it while driving, and if the driver looks at it and drives it so that the graph is as flat and smooth as possible, it becomes an eco-drive.

  For example, the first axis can be the horizontal axis and the second axis can be the vertical axis, or conversely, the first axis can be the vertical axis and the second axis can be the horizontal axis. Moreover, it is good also as a graph of pseudo | simulation three-dimensional display by arrange | positioning each axis inclining, without making it parallel with the upper and lower sides, and the left and right sides of a screen.

  (5) Further, the standby screen display means may display the economy traveling speed as the eco-driving information. As the display related to the economic travel speed, for example, when the economic travel speed is displayed numerically or when the vehicle speed is displayed in a graph as shown in (3), the guideline is displayed at a position corresponding to the economic speed in the graph. (Refer to (15) described later).

  In addition, it is good to display a guideline in the position corresponding to the value used as an eco-drive not only on speed but on a graph. For example, a line of economic acceleration may be drawn in the acceleration graph (see (15) described later).

  In this way, it can be seen at a glance how much the own speed and acceleration deviate from the speed and acceleration at which eco-drive is achieved. Therefore, eco-driving can be realized more easily.

  (6) In addition, an idling time detecting means for detecting an idling time of the engine is provided as the drive state detecting means, and the standby screen display means detects the idling of the engine detected by the idling time detecting means as the eco-drive information. It is good to display about time. As the idling time detection means, for example, the time when the vehicle speed detected by the speed detection means is 0 may be detected. Further, as the display relating to the idling time, for example, the idling time may be displayed as a numerical value such as “idling time n seconds” (n is a numerical value indicating the number of seconds of idling time).

  (7) When the speed detection means is provided as the drive state detection means, for example, GPS can be used as the speed detection means. However, when speed measurement is performed by GPS, there is a problem that it is difficult to measure stopping or low speed travel. Therefore, the engine speed may be used as the drive state detection means. As a method for detecting the engine speed, for example, a method for detecting the engine speed from alternator noise or ignition noise superimposed on the power line of the vehicle may be used.

  In addition, the drive state detecting means can be configured as means for detecting various information flowing on the in-vehicle LAN existing in the vehicle, for example. The drive state detection means may be a temperature detection means for detecting the temperature outside the vehicle, for example. For example, when the temperature outside the vehicle is a predetermined temperature (in a temperature range in which people feel comfortable even without using an air conditioner), an indication that eco driving can be performed when the air conditioner is stopped is displayed as eco driving information. You may make it display. At this time, it may be determined whether this display is performed in consideration of the operating state of the air conditioner, the temperature in the vehicle, and the like. As the drive state detection means, means for detecting the engine speed, the vehicle vibration state, and the gear shift state may be used as will be described later.

  And as a drive state detection means, the various means mentioned above can be used in combination, for example. Further, for example, based on the detection state of any of the various means described above, it may be determined whether to use the detection state of another means.

(8) For example, the drive state detecting means includes an engine speed detecting means for detecting the engine speed and a vehicle speed detecting means for detecting the vehicle speed, and the standby screen display means is detected by the vehicle speed detecting means. When the vehicle speed is less than a predetermined speed, the eco-drive information is displayed based on the engine speed detected by the engine speed detecting means, and the vehicle speed detected by the vehicle speed detecting means is displayed. When the vehicle speed is equal to or higher than a predetermined speed, the eco-drive information may be displayed based on the vehicle speed detected by the vehicle speed detecting means. In this way, even when the vehicle speed detecting means is configured by a GPS or the like in which the vehicle speed detecting means is in a low speed state (less than a predetermined speed) and it is difficult to obtain sufficient accuracy, it is possible to provide highly accurate eco-drive information. . How to accelerate without depressing the accelerator at the start of the car has a big impact on ecology. Therefore, with such a configuration, the detection of the low speed state can be performed with high accuracy, so that a particularly excellent effect is exhibited. For example, when the speed is below a predetermined speed, a change in the engine speed is detected by the superimposed power supply noise, and an eco-driving judgment or an eco-warning is issued. It is better to use GPS measurement data.
Further, for example, the standby screen display means may display the ratio between the speed and the engine speed as eco-drive information, or may be used for determination of eco-drive.

  (9) The drive state detection means includes a vibration detection means for detecting the vibration of the vehicle instead of the engine speed detection means or together with the engine speed detection means, and the standby screen display means includes the vibration detection means. The eco-drive information may be displayed based on the vibration state detected by the means.

  (10) Further, the drive state detection unit includes a gear shift state detection unit that detects a gear shift state, and the standby screen display unit displays the eco-drive information based on the gear shift state detected by the gear shift state detection unit. You may do it. As the gear shift detection means, for example, a sensor for detecting a shift position or information flowing through the in-vehicle LAN can be used. Further, the shift state of the gear may be detected from the speed data by GPS and the engine speed.

  For example, the idling time and other various times can be detected more accurately when detected using GPS. As eco-drive information, the engine speed may be added to the speed and acceleration in the graph display.

  (11) Further, the drive state detection means includes vehicle acceleration detection means for detecting vehicle acceleration, and the standby screen display means uses the vehicle acceleration detected by the vehicle acceleration detection means as the eco-drive information. It is good to display with the inclination of a straight line. For example, a straight line may be drawn and displayed so that the acceleration is zero if it is horizontal, is accelerating if it is right, and is decelerating if it is right, and the acceleration increases as the angle is steep. For example, it may be displayed like an analog meter. As a result, the acceleration state is instantly known. It is easier to understand if the color or thickness of the straight line is changed within a predetermined acceleration range. The straight line may be superimposed on a graph that displays the history by speed and acceleration. In this case, it is easy to understand if it is displayed so as to touch the current speed point of the graph (tangent line).

  (12) As described above, the eco-drive information can be displayed in a graph or numerically as described above. The eco-drive information can be displayed together with the eco-drive information or as the eco-drive information. The drive state detected by the state detection means may be displayed in the form of an analog needle meter. Analog needle type meter can judge the movement of elasticity sensuously and can learn eco-driving (eco-driving) without gazing at the meter. For example, it may be displayed as a sports meter-like ecometer.

  (13) The analog needle meter is provided with a scale at a position indicated by the analog needle meter, the scale is displayed in a different color for each predetermined zone, and the color of the scale of the zone indicated by the analog needle meter It is preferable to display a color based on the background color of the standby screen.

  (14) The standby screen display means displays a digital meter together with the analog needle meter, the analog needle meter is provided with a scale at a position indicated by the analog needle meter, and the scale has a predetermined scale. Different colors may be displayed for each zone, and the scale color of the zone indicated by the analog needle meter and the color of the digital meter may be displayed in association with each other.

  (15) Further, for example, the drive state detection means includes vehicle acceleration detection means for detecting vehicle acceleration, and the analog needle meter is a vertical needle when the acceleration is 0, It may be displayed so that the needle is tilted from the vertical direction to the right during acceleration and the needle is tilted from the vertical to the left during deceleration.

  (16) Further, for example, the analog needle meter may display a needle indicating the speed of the vehicle and a guide needle indicating the eco speed. For example, a display that moves a needle representing the speed clockwise according to an increase in the speed of the vehicle and a hand that represents the speed counterclockwise according to a decrease in the speed is performed. A guide needle indicating the eco speed may be displayed separately from the needle to be displayed. The guide needle (eco-speed display needle) is, for example, 5 when detecting that the vehicle speed has changed from 0 (when the vehicle acceleration detecting means is provided, for example, when detecting an acceleration of a predetermined value or more), 5 When moving at a rate of 20 km / h per second up to 60 km / h and the vehicle speed is constant speed running for 5 seconds, it is moved so as to overlap the needle (actual speed tension) representing the speed. In this way, it is possible to perform eco-driving simply by increasing the vehicle speed along the movement of the guide needle. Note that the speed limit of the currently traveling road may be acquired, and the guide needle may be moved at a predetermined rate up to the acquired speed limit. For example, the position information and the speed limit information may be stored in association with each other, the current position may be detected by GPS or the like, and the speed limit corresponding to the current position may be acquired based on these.

  (17) In particular, the standby screen display means may display, as the eco-drive information, a display indicating an eco-drive status index together with a display based on the drive status detected by the drive status detection means. For example, as described above, the values and lines (lines) of the speed and acceleration in the eco-drive state may be displayed in a graph or an analog needle meter.

  The eco-drive state refers to a drive state that is an eco-drive. The eco-driving state is, for example, a record of the driving state obtained by running the vehicle while recording the driving state detected by the driving state detecting means, and running corresponding to the eco-driving, and driving that is not eco-driving (for example, economy) It may be obtained based on a difference from a drive state record obtained by traveling deviating from the traveling speed, sudden acceleration, sudden deceleration, or the like.

  (18) When the standby screen display unit changes the display mode based on the drive state detected by the drive state detection unit as the eco-drive information based on the degree of coincidence between the drive state and the eco-drive state. Good.

  (19) For example, the display mode based on the drive state may be changed by changing the color. For example, the speed color of the speed display may be changed steplessly depending on the instantaneous fuel consumption factor.

  Further, for example, the display mode based on the drive state may be changed by enlargement / reduction. For example, when the graph is displayed, if the state is not eco-driving, the graph portion may be enlarged. How to zoom in, for example, a mode in which the entire screen is smoothly moved around that part, or a picture of a magnifier is displayed and the graph should be magnified in the picture of the magnifier ) It is good to take an aspect of enlarging it in the center. In addition, the enlargement is canceled when a certain time elapses or when the state returns to the eco-driving state. The release should be done smoothly. Moreover, at the time of expansion, it is good to alert | report an alarm sound and the reason for expansion (reason which is not ecological).

Further, the display mode based on the drive state may be changed by changing the character to be displayed. For example, when eco-driving is performed (when the degree of coincidence between the detected driving state and the eco-driving state is high), the character may be changed so that the creature evolves, or when the eco-driving is not performed (detected) If the degree of coincidence between the driving state and the eco-driving state is low), the character may be changed so that the creature degenerates. That is, it is possible to learn eco-driving while having fun by changing the character to be displayed instead of (not only) displaying a score or displaying a graph or the like. For example, as for the drive state, it is preferable to detect a sudden start or a sudden handle with a speed monitor by GPS and an acceleration sensor. Biological evolution is, for example, displaying an amoeba in the initial state, and if it is an eco-drive, it becomes a daphnia. Alternatively, it may be a cute girl or a good cat. On the other hand, if it is not eco-driving, it may be a dinosaur, a monkey, or a bad cat. In this way, eco-driving can be enjoyed like a game.
As described above, the change of the display mode based on the drive state may be performed by at least one of color change, enlargement / reduction, and change of character to be displayed.

  (20) The standby screen display means may calculate and display points as the eco-drive information based on the degree of coincidence between the drive status detected by the drive status detection means and the eco-drive status. For example, the points may be increased when a drive state corresponding to an eco drive is detected, and the points may be decreased when a drive state contrary to the eco drive is detected. In this way, the driver can be motivated to drive for an eco-drive aiming at a high point.

  (21) In addition, when the degree of coincidence between the drive state detected by the drive state detection means and the eco-drive state is a predetermined value or more, it is preferable to notify the content of giving up the driver. By “giving up when it ’s good”, you can try eco-driving while having fun.

  (22) In addition, a function is provided for notifying when the degree of coincidence between the drive state detected by the drive state detection means and the eco-drive state reaches a predetermined state, and the notification is made during the occurrence of the event or the occurrence of the event It is good not to carry out in at least one of the cases within a predetermined time. For example, when the eco-drive state is lost (when the degree of coincidence is equal to or less than a predetermined value), a warning may be notified, or as shown in (21), the degree of coincidence between the drive state and the eco-drive state is predetermined. In the case where the value is greater than or equal to the value, a notification of the content of giving up the driver may be given. This notification is not performed during the occurrence of the event or within a predetermined time from the occurrence of the event, so that the notification at the time of the event occurrence (for example, when the event occurrence screen shown in (1) is displayed, It is possible to prevent the driver from feeling bothered when the degree of coincidence between the driving state and the eco-driving state becomes a predetermined state during the output of the notification sound) or immediately after the notification. . For example, when sudden acceleration / deceleration is detected as the drive state, an eco warning is issued.However, if sudden deceleration is detected during an approach alarm to the speed measurement device or within a predetermined time after the approach alarm, Since it is a sudden deceleration to approach the speed measuring device, it is better not to use the eco warning.

  (23) It is preferable to output a sound based on the drive state detected by the drive state detection means. In particular, sound output is preferably performed in proportion to the degree of inconsistency between the drive state detected by the drive state detection means and the eco-drive state. For example, in (11) to (14), when the speed and acceleration of the vehicle are displayed with the inclination of a line (needle), the sound may be output with a pitch or volume corresponding to the magnitude of the inclination. For example, as the inclination increases, the pitch is increased and the volume is increased. In this way, it is possible to sensuously understand how far the eco-driving state is deviated from the pitch and loudness.

  The sound output may be obtained by, for example, acquiring a noise sound accompanying engine rotation from a power supply line or the like and amplifying it. In this way, it is possible to sensuously and intuitively learn driving operations that are eco-driving and driving operations that are not eco-driving from the loudness and pitch of noise.

Note that the sound is output only when the discrepancy between the drive status detected by the drive status detection means and the eco-drive status exceeds a predetermined discrepancy, so that the sound can be output without looking at the standby screen. You can tell if you are in an eco-driving state with or without. Moreover, it can reduce that a user feels troublesome.
(24) The standby screen display means may display the eco-drive information by displaying a 3D object.

  (25) At the start of displaying the eco-drive information, an animation may be displayed so that the 3D object enters the screen from outside the screen.

(26) The standby screen display means may display the eco-drive information as a plurality of objects, and for overlapping objects among the plurality of objects, display at least a part of the overlapping objects as a transparent color object. .
(27) It can be realized as a program for causing a computer to realize the function as each means in the in-vehicle electronic device according to any one of (1) to (26).

  According to the present invention, it is possible to provide a vehicle-mounted electronic device that can make a driver aware of eco-driving more naturally than before, and can acquire a driving operation to become an eco-drive sensuously and intuitively. be able to.

  1 and 2 show the configuration of a radar detector which is a preferred embodiment as an in-vehicle electronic device according to the present invention. As shown in FIG. 1, the solar panel 2 and the switch unit 3 are arranged on the upper surface of the case body 1, the microwave receiver 4 is arranged inside the front side of the case body 1, and the display unit 5 is arranged on the rear surface of the case body 1. An alarm lamp 6 and an infrared communication device 7 are arranged. A GPS receiver 8 is disposed inside the upper surface of the case body 1. Further, an adapter jack 9 is disposed on one side surface of the case body 1, and a power switch 10 and a DC jack 11 are disposed on the other side surface. A speaker is also built in the case body 1. In the present embodiment, the size and shape of the display unit 5 are made larger than before (in particular, the height direction is widened). Accordingly, the height H on the rear side of the case body 1 on which the display unit 5 is mounted is made sufficiently larger than the height H0 of other parts. With this configuration, it is possible to provide the display unit 5 having a larger screen than in the past.

  As shown in FIG. 2, the infrared communication device 7 transmits and receives data to and from a communication device incorporating an infrared communication device such as a mobile phone 12. The adapter jack 9 is a terminal for connecting the memory card reader 13. By connecting the memory card reader 13 to the adapter jack 9, data stored in the memory card 14 attached to the memory card reader 13 can be taken in. More specifically, the data stored in the memory card 14 includes update information such as information on a new target (position information including longitude and latitude, type information, etc.), and the update information passes through the control unit 18. Thus, the data is stored (downloaded) in the database 19 built in the apparatus, and the data is updated. 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 information related to a certain target at the time of shipment, and data on the target added after that is updated as described above. Data update can also be performed via the infrared communication device 7.

  The DC jack 11 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. Furthermore, the radar detector according to the present embodiment includes a wireless receiver 15 and a remote control receiver 16. The wireless receiver 15 receives incoming radio waves having a predetermined frequency. The remote control receiver 16 performs data communication with a remote control (portable device: handset) 17 and performs various settings for the device. The switch unit 3 is also connected to the control unit 18 (not shown) so that the same setting as the remote controller 17 can be performed.

  Further, the control unit 18 executes predetermined processing based on information input from the various input devices (the GPS receiver 8, the microwave receiver 4, the wireless receiver 15, etc.) corresponding to the drive state detecting means. Then, a predetermined alarm / message is output using an output device (display unit 5, alarm lamp 6, speaker 20, etc.). 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 realized by being stored on the EEPROM of the control unit 18 as a program executed by the computer included in the control unit 18 and executed by the computer included in the control unit 18.

  FIG. 3 is a diagram illustrating a drawing example of the standby screen 40 displayed on the display unit 5 by the control unit 18 in the radar detector of the present embodiment. FIG. 4 is a diagram showing an alarm screen 60 as an event occurrence screen displayed on the display unit 5 by the control unit 18 in the radar detector of the present embodiment.

  The GPS receiver 8 outputs the current position, speed, altitude, and current time to the control unit 18. The control unit 18 acquires the current position, speed, altitude, and current time every second from the GPS receiver 8, and as a predetermined event, the current position is determined according to the target position stored in the database 19 and the predetermined position. When it is a distance (for example, 1 km or less), an approach warning to the target is output from the speaker 20 and an alarm screen 60 is displayed on the display unit 5.

  When the microwave receiver 4 receives a microwave emitted by the speed measuring device as a predetermined event, a microwave reception alarm screen is displayed as a predetermined event generation screen, and the wireless receiver is displayed as the predetermined event. When 15 receives a radio wave of a predetermined frequency emitted by the emergency vehicle, an emergency vehicle approach warning screen is displayed as a predetermined event occurrence screen.

  Except when such a predetermined event occurs and the predetermined event occurrence screen is displayed, processing for drawing the standby screen 40 is performed. That is, the radar detector of the present embodiment starts the operation when the power switch 10 is turned on, and performs a process of drawing the standby screen 40 except when a predetermined event occurs.

The standby screen 40 includes an icon display area in the upper part, a display area for points and graphs in the middle part, and a display area for total points, time, and speed in the lower part. In the icon display area 41, an icon indicating the current setting state (for example, various modes) and information on the travel location (for example, whether the vehicle is a parking prohibition monitoring area) is displayed as in the conventional radar detector.
The point and graph display area has a point display area on the left side and a graph display area on the right side.

  The graph display area is an area for drawing the speed graph 43 in the upper stage and the acceleration graph 47 in the lower stage. The speed graph 43 is a graph in which the vertical direction indicates speed and the horizontal direction indicates time, and has a vertical axis 46, a horizontal axis 42, and an economic speed reference line 44. The control unit 18 acquires speed information from the GPS receiver at intervals of 1 second, and represents the acquired value as the size of a bar (vertical line). That is, when the power is turned on, drawing of a bar is started from a position adjacent to the right side of the vertical axis 46, and the next bar is drawn at a position adjacent to the previously drawn bar. In this way, a bar is drawn to the right end of the graph display area in 4 minutes. When the drawing to the right end of the graph display area is made, the first drawn bar is erased and moved to the left by one bar, and then the bar is drawn. In this way, the graph is drawn while scrolling thereafter. The bar size is 0 km / h per hour, the bar size is 0, the speed is 60 km / h, and the speed reaches the position of the economic speed reference line 44. The speed of the vertical axis 46 is 110 km / h. Draw at the same height as the top edge. In addition, when exceeding 110 km / h, it draws with the magnitude | size which reaches the height similar to the upper end of the vertical axis | shaft 46. FIG. Further, acceleration is calculated based on a history of speed information acquired from the GPS receiver 8. Needless to say, an acceleration sensor or the like may be mounted independently, and the acceleration may be calculated by reading the value of the acceleration sensor from the control unit 18. The acceleration graph 47 is a graph in which the vertical direction indicates acceleration and the horizontal direction indicates time, and includes a vertical axis 46, a horizontal axis 42, and a line 45 of acceleration 0. In the present embodiment, the speed graph 43 and the acceleration graph 17 use the vertical axis 46 and the horizontal axis 42 in common, but the axes may be displayed separately. In this case, the acceleration zero line 45 and the horizontal axis can be shared. The control unit 18 acquires speed information from the GPS receiver 8, obtains acceleration from the history of the acquired speed information, and represents the acquired value as the size of a bar (vertical line). That is, when the obtained acceleration indicates acceleration, a bar corresponding to the magnitude of the acceleration is drawn above the acceleration zero line 45, and when the acceleration indicates deceleration, the acceleration is below the acceleration zero line 45. Draw a bar according to the size of the. In addition, the bar drawing method is the same as that of the speed graph 43 described above.

  The point display area includes, in order from the top, a point display area 48a for rapid acceleration, a point display area 48b for rapid deceleration, a point display area 48c for idling time, and a point display area 48d for economic travel speed. Each point display area 48 (48a to 48d) has an initial value of 70, a maximum value of 100, a minimum value of 0, and +1 (additional points) if the state corresponding to the eco-drive continues for a predetermined time. This is an area where the result of -1 (decrease) is displayed numerically when a state not corresponding to is continued for a predetermined time. That is, the point of sudden acceleration is deducted if it is determined that the acceleration is equivalent to sudden acceleration, the point of sudden deceleration is deducted if it is determined that the vehicle is suddenly decelerated due to sudden braking, etc., and the idling time point is When the stopping time exceeds a predetermined time (for example, 2 minutes), points are deducted every predetermined time (for example, 1 minute), and the point of the economic running speed is a predetermined range (for example, 60 / h / hour plus) The points are deducted when the time during which the vehicle is not traveling in the range of minus 5 km / h continues for a predetermined time (for example, 5 minutes). When the state other than the above continues for each point for a predetermined time (for example, 2 minutes), the respective points are added. The state in which points are deducted / added may be determined based on the actual measurement results after creating a state that is not eco-driving. The idling time may be detected by detecting a time when the speed acquired from the GPS receiver 8 is zero.

The lower total point display area 49 includes a point display area 48a for rapid acceleration, a point display area 48b for sudden deceleration, a point display area 48c for idling time, and an average value of points displayed in the point display area 48d for economic travel speed. Is displayed.
The time display area 51 displays the current time acquired from the GPS receiver 8, and the hourly speed display area 50 displays the hourly speed acquired from the GPS receiver 8.

  As described above, the control unit 18 determines whether a predetermined event occurs, that is, for example, whether the current position is a predetermined distance (for example, 1 km or less) from the position of the target stored in the database 19. 4 is output from the speaker 20 and an alarm screen 60 shown in FIG. 4 is displayed on the display unit 5 as an event generation screen.

  The alarm screen 60 includes an icon display area 61 and an alarm object name display area 62 on the upper left side, an alarm object icon display area 63 on the middle left side, and a current speed display area 64 and a speed limit display area 65 on the lower left side. The alarm screen 60 includes a distance display area 66 from the alarm object on the upper right side, a radar scope display area 67 for displaying the relationship between the position 67a of the alarm object and the vehicle position 67b as a bird's eye view on the right middle, and a lower right area. A time display area 68 for displaying the current time acquired from the GPS receiver 8 is provided.

  The control unit 18 determines whether or not the current position acquired from the GPS receiver 8 is substantially coincident with the position of the target stored in the database 19 (for example, the distance between the two is 10 m or less). If it is determined, the speaker 20 outputs a sound indicating that the approach warning to the target is to be ended. In other words, the control unit 18 outputs a voice, for example, “passes the position of the speed measuring device”. After outputting the sound, the control unit 18 performs display processing of the standby screen 40 on the display unit 5.

  In this way, information about the alarm can be obtained at the time of alarm occurrence, while eco-drive information is displayed as a graph or points on the standby screen 40 in the standby state where no alarm has occurred, You can be aware of eco-driving on a daily basis.

  Particularly, since the user often pays attention to the alarm screen 60, the content of the standby screen 40 is often naturally taken care of even when switching from the alarm screen 60 to the standby screen 40. Therefore, it is possible to deeply impress the contents of the standby screen 40, that is, eco-drive information, by using the attention to the alarm screen 60. Therefore, it is possible to make the driver aware of eco-driving more naturally than before. In particular, since the sound is output when the display of the alarm screen 60 is terminated, the driver can be efficiently and effectively aware of the eco-driving.

  In addition, the eco-drive information changes the graphs and points as time passes. If the driver looks at the display unit 5 and drives when the vehicle is stopped so that each point becomes high so that the graph is as flat and smooth as possible, the vehicle becomes eco-driving.

  In this embodiment, the time axis is taken in the horizontal direction and the physical quantity of speed / acceleration is taken in the vertical direction. For example, the time axis is taken in the vertical direction and the physical quantity of speed / acceleration is taken in the horizontal direction. You may make it draw and draw.

  Since the economic speed reference line 44 serving as a guideline is displayed at a position corresponding to the economic speed, it is possible to see at a glance how much the self speed has deviated from the speed and acceleration to become an eco-drive and when it has deviated. I understand. Therefore, it can be determined what kind of driving should be performed in the future, and eco-driving can be easily realized.

  In this embodiment, the eco-driving information related to idling is displayed as a numerical value of points in the idling time point display area 48c. For example, the idling time n seconds (n is the idling time seconds) is displayed on the standby screen 40. It may be displayed numerically as in (Numeric value representing number).

  In the present embodiment, the GPS receiver 8 is used for speed detection. However, when speed measurement is performed using GPS, there is a problem that it is difficult to measure stopping or traveling at low speed. Therefore, it is preferable to use the engine speed. As a method for detecting the engine speed, for example, a method for detecting the engine speed from alternator noise or ignition noise superimposed on the power line of the vehicle may be used. For example, when power is supplied from the DC jack 11, power is supplied from the cigar socket of the vehicle via the cigar plug cord. Therefore, the engine speed is detected from the alternator noise or ignition noise of the power supply. Should be detected. Various known methods can be used as this method.

  When the vehicle speed detected by the GPS receiver 8 is less than the predetermined speed, the eco-drive information is displayed based on the engine speed, and the vehicle speed detected by the GPS receiver 8 is the predetermined speed. In the above case, the graphs and points in FIG. 3 may be displayed based on the vehicle speed detected by the GPS receiver 8.

  In this way, even when the vehicle speed detection means is in a low speed state (less than a predetermined speed) and is configured by the GPS receiver 8 that is difficult to obtain sufficient accuracy, a highly accurate graph or point can be obtained. Can be provided. How to accelerate without depressing the accelerator at the start of the car has a big impact on ecology. Therefore, with such a configuration, the detection of the low speed state can be performed with high accuracy, so that a particularly excellent effect is exhibited. For example, the standby screen 40 may further display a ratio between the speed and the engine speed as eco-drive information.

  In addition, for example, various types of information flowing on the in-vehicle LAN existing in the vehicle can be detected. Further, for example, a temperature sensor that detects the temperature outside the vehicle is connected to the control unit 18, and the temperature outside the vehicle is, for example, a predetermined temperature (in a temperature range in which a person feels comfortable without using an air conditioner). In this case, an indication that eco-driving is possible when the air conditioner is stopped may be displayed on the standby screen 40 as eco-driving information. At this time, it may be determined whether this display is performed in consideration of the operating state of the air conditioner, the temperature in the vehicle, and the like. Further, a means for detecting the engine speed, the vehicle vibration state, and the gear shift state may be used.

  A vibration sensor that detects the vibration of the vehicle instead of the engine speed or together with the engine speed is connected to the control unit 18, and the standby screen 40 is a graph shown in FIG. 3 based on the engine speed detected by the vibration sensor. Or points may be displayed. A known method can be used as a method of detecting the engine speed from the vibration.

  In addition, a gear shift state detector that detects the gear shift state may be connected to the control unit 18, and the standby screen 40 may display the graph and points of FIG. 3 based on the gear shift state detected by the gear shift state detector. . For example, when the gear shift state is neutral or parking and the speed is zero, and vibration is detected by the vibration sensor, it is determined that the engine is in the idling state. It is good to display by subtracting. As the gear shift detector, for example, a sensor for detecting a shift position or information flowing through the in-vehicle LAN can be used. Further, the gear shift state may be detected from the speed data obtained by the GPS receiver 8 and the engine speed. The standby screen 40 may also display the engine speed as eco-drive information.

  The standby screen 40 may display the acceleration of the vehicle as a slope of a straight line as eco-drive information. That is, for example, it is preferable to display the obtained latest acceleration as a slope in the drawing area of the speed graph 43 in the graph display area as a tangent line that touches the right end of the speed graph 43 (that is, the latest speed). In this way, for example, the current acceleration is zero if it is horizontal, is currently accelerating if it rises to the right, is currently decelerating if it is right, and the acceleration is increased as the angle gets sharper. As a result, the acceleration state is instantly known. It is easier to understand if the color or thickness of the straight line is changed within a predetermined acceleration range.

  As described above, the display mode of the eco-drive information can be displayed in a graph or numerical value. However, the speed and acceleration can be displayed together with the eco-drive information or as eco-drive information using an analog needle type. It may be displayed in the form of a meter. Analog needle type meter can judge the movement of elasticity sensuously and can learn eco-driving (eco-driving) without gazing at the meter. For example, it may be displayed as a sports meter-like ecometer shown in FIG.

  5 and 6 are diagrams showing another embodiment of the standby screen 40. FIG. The standby screen 40 displays an analog needle accelerometer 80 on the left side. In the analog needle type accelerometer 80, as the eco-drive information, the acceleration of the vehicle calculated from the change amount of the speed history acquired from the GPS receiver 8 is displayed, and the rapid deceleration guideline 83 serving as an indicator of the eco-drive state and The rapid acceleration guideline 84 is displayed. When the acceleration is zero, it is displayed as a vertical acceleration needle 82 as shown in FIG. 5, and when accelerating, the acceleration needle 82 is tilted to the right as shown in FIG. Display is made so that 82 is tilted. The rapid deceleration guideline 83 is displayed at the boundary position between the normal deceleration state and the rapid deceleration state that is not eco-drive, and the rapid acceleration guideline 84 is the boundary position between the normal acceleration state and the rapid acceleration state that is not eco-drive Is displayed. To determine the position where the rapid deceleration guideline 83 or rapid acceleration guideline 84 is displayed, it is only necessary to determine the appropriate position by performing rapid deceleration and rapid acceleration while the radar detector is mounted on an actual vehicle. .

  Further, as shown in FIGS. 5 and 6, the standby screen 40 displays an analog needle speed meter 90 on the right side. The analog needle type speed meter 90 shows a speed hand 93 indicating the speed of the vehicle, an eco speed guide needle 92 indicating the eco speed, and a minimum value of the economic speed when traveling on the highway (for example, 80 km / h). A high-speed traveling economic speed minimum value guideline 94a and a high-speed traveling economic speed maximum value guideline 94b indicating the maximum value of the economic speed when traveling on a highway (for example, 90 km / h) are displayed. FIG. 5 shows a display state when the speed is 0, and FIG. 6 shows a display state when the speed is 34 km / h. As shown in FIGS. 5 and 6, the speed hand 93 moves clockwise as the vehicle speed increases and displays counterclockwise as the speed decreases. In addition, the analog needle type speed meter 90 displays an eco speed guide needle 92 indicating the eco speed separately from the speed hand 93.

  The eco-speed guide needle 92 moves to 60 km / h at a rate of 20 km / h in 5 seconds when detecting that the speed acquired from the GPS receiver 8 has changed from 0. At this time, the eco speed guide needle 92 may be drawn so that the instructed speed increases smoothly (gradually). This eco-speed guide needle 92 is an indicator of eco-driving at the start. That is, when the speed hand 93 is increasing faster than the extent of the increase in the eco speed guide needle 92 (the actual acceleration of the vehicle speed is large), it is estimated that the vehicle is suddenly started and is not in the eco drive state. it can. Therefore, it can be understood that the driver should drive (step on the accelerator) such that the current vehicle speed (speed indicated by the speed hand 93) is slower than or equal to the eco speed guide needle 92.

  In addition, as one of eco-drives, there is a case of traveling at a constant speed without changing the speed. Therefore, for example, when it can be considered that the vehicle has traveled at a constant speed for 5 seconds based on the speed acquired from the GPS receiver 8, it can be said that the vehicle is in the eco-drive state, so the eco-speed guide needle 92 is moved so as to overlap the speed hand 93. . Thus, for example, when traveling at a constant speed of 50 km / h, if the eco-speed guide needle 92 indicates 60 km / h, the driver accelerates to approach 60 km / h and There is a risk of repeated acceleration and deceleration, such as slowing down without being able to maintain 60 km / h due to traffic conditions, etc., but when driving at a constant speed, it is stable at the speed that matches the traffic conditions of the road. (As a result, it can be said that the vehicle is traveling at the economic speed at that time), and the current speed that has become constant (speed indicated by the speed hand 93) and the eco speed guide needle 92 are drawn in an overlapping manner. By doing so, constant speed driving can be promoted.

  Further, when the speed of constant speed travel exceeds 60 km / h, for example, there is a possibility of traveling on a highway. Therefore, when traveling at a constant speed, the speed hand 93 and the eco speed guide needle 92 are used. And draw over.

  Note that when the maximum speed indicated by the eco speed guide needle 92 is set and the vehicle travels at or above the maximum speed, the eco speed guide needle 92 may be drawn so as to indicate the maximum speed. In this way, for example, when traveling at a constant speed exceeding the maximum value of the economic speed (for example, 90 km / h) when traveling on a highway, the eco speed guide needle 92 sets the maximum value. By pointing, it is possible to promote constant speed running at economic speed. Note that the type of road on which the vehicle is traveling may be determined, and the maximum speed indicated by the eco-speed guide needle 92 may be varied according to the road type.

  In FIG. 5, since the speed acquired from the GPS receiver 8 is 0 km / h, the speed hand 93 indicates 0 km / h, and the eco speed guide needle 92 also indicates 0 km / h. Therefore, they are displayed overlapping each other. 6 shows that the speed acquired from the GPS receiver 8 is 34 km / h, so the speed hand 93 points to 34 km / h, and the eco speed guide needle 92 has changed from the state where the speed acquired from the GPS receiver 8 is zero. Is detected after 5 seconds, indicating a speed of 20 km / h. In the state of FIG. 6, since the eco speed guide needle 92 is in the counterclockwise direction (left direction) of the speed hand 93, it can be seen at a glance that the speed is excessively increased (starts suddenly). Further, in the state of FIG. 6, the acceleration needle 82 of the analog needle type accelerometer 80 is on the right side of the rapid acceleration guideline 84, and it can be seen at a glance that it is in the sudden acceleration state.

  In this way, it can be seen at a glance whether or not the vehicle is eco-driving from the difference in position between the eco-speed guide needle 92 and the speed hand 93. Further, the eco-driving can be performed only by increasing the vehicle speed (stepping on the accelerator) so that the speed hand 93 moves along the movement of the eco-speed guide needle 92. Further, when driving on a highway, eco-driving can be easily performed by driving so that the speed hand 93 comes between the high-speed driving economic speed minimum value guideline 94a and the high-speed driving economic speed maximum value guideline 94b.

  The eco speed guide needle 92 is moved up to 60 km / h. For example, the position and speed limit are stored in the database 19 in association with each other, and the current position acquired from the GPS receiver 8 and the database 19 are stored. It is also possible to acquire the speed limit of the location where the vehicle is currently traveling from the stored position and move the eco speed guide needle 92 to the acquired speed limit.

  The standby screen 40 may change the display mode as eco-drive information based on the degree of coincidence between the drive state and the eco-drive state. For example, the display mode may be changed by changing the color. For example, the display color of the hourly speed acquired from the GPS receiver 8 displayed in the hourly speed display area 50 may be changed depending on whether the vehicle is an eco-drive. For example, if the speed is in the range of 60 km / h plus or minus 10 km / h, the color is green, and in the case of other speeds, the color is red. Similarly, the colors of the bars of the speed graph 43 and the acceleration graph 47 may be changed depending on whether or not the vehicle is an eco drive.

  Also, for example, when the graph is being displayed, if the state is not eco-driving, the portion of the graph may be enlarged and displayed. For example, the magnified display can be enlarged by smoothly moving the entire screen around that part, or by displaying a magnifier picture and enlarging the graph in the magnifier picture (eco It is better to zoom in on the center. In addition, the enlargement is canceled when a certain time elapses or when the state returns to the eco-driving state. The release should be done smoothly. Moreover, at the time of expansion, it is good to alert | report an alarm sound and the reason for expansion (reason which is not ecological).

  Also, for example, when the character is displayed on the standby screen 40 and eco-driving is performed (when the detected speed is within the range of the economic traveling speed (for example, 60 km / h) and plus or minus 10 km / h), the living thing evolves. If you do not eco-drive (if the detected speed is not in the range of economic driving speed (for example, 60 km / h) and plus or minus 10 km / h), the creature will degenerate. The character may be displayed to change. That is, it is possible to learn eco-driving while having fun by changing the character to be displayed instead of (not only) displaying a score or displaying a graph or the like. Biological evolution is, for example, displaying an amoeba in the initial state, and if it is an eco-drive, it becomes a daphnia. Alternatively, it may be a cute girl or a good cat. On the other hand, if it is not eco-driving, it may be a dinosaur, a monkey, or a bad cat. In this way, eco-driving can be enjoyed like a game.

  In addition, when the total point exceeds 90 points, it is preferable to notify the driver of the content of giving up. By giving up if you like it, you can try eco-driving while having fun.

  In addition, for example, when acceleration is obtained based on the history of speed acquired from the GPS receiver 8 and acceleration corresponding to sudden acceleration / deceleration is obtained, the rapid warning / sudden deceleration is sounded from the speaker 20 with an audio warning. You may make it alert | report. For example, the eco alarm is notified by voice such as “rapid acceleration” or “rapid deceleration”. However, this notification is not performed during the display of the alarm screen 60 as shown in FIG. 4 and for 30 seconds after the display of the alarm screen 60 is completed. In this way, if a sudden deceleration is detected during an approach warning to the speed measurement device or within a predetermined time after the approach alert, the eco warning is issued because the sudden deceleration is due to the approach to the speed measurement device. This eliminates the user's annoyance.

  When acceleration corresponding to sudden acceleration / deceleration is obtained, that is, as shown in FIG. 6, when the acceleration needle 82 is further on the right side beyond the sudden acceleration guideline 84, the magnitude of the inclination is increased. The sound is output with the corresponding pitch and volume. For example, as the inclination increases, the pitch is increased and the volume is increased. In this way, it is possible to sensuously understand how far the eco-driving state is deviated from the pitch and loudness. In addition, since the relationship between the acceleration needle 82 and the rapid acceleration guideline 84 displayed on the standby screen 40 and the relationship between the pitch and the volume can be acquired, the acceleration needle 82 can be adjusted according to the pitch and the volume without gazing at the acceleration needle 82. You can imagine the location, and you can learn eco-driving more intuitively. In addition, when displaying the acceleration of the vehicle as the slope of the straight line as the eco-drive information, it is preferable to output the sound with a pitch or volume corresponding to the magnitude of the slope.

  In addition, when power is supplied from the DC jack 11, power is supplied from the cigar socket of the vehicle via the cigar plug cord. Therefore, the alternator noise sound of the power supply is amplified and output as sound. You may do it. In this way, the relationship between the state of the engine and eco-driving can be known from the loudness and pitch of the noise sound, and the driving operation that becomes eco-driving and the driving operation that does not become eco-driving are sensed according to the state of the sound.・ You can learn intuitively.

  According to the radar detectors of the embodiments as described above, the driver can be more naturally aware of eco-driving than before, and the driving operation to become eco-driving is acquired sensorially and intuitively. be able to.

  The display mode of the eco-drive information is not limited to these, and various modes can be adopted. For example, as shown in FIG. 7, on the graph (speed graph 43, acceleration graph 47) and numerical values (numerical values displayed in the point display area 48, the total point display area 49, and the hourly speed display area 50) shown in FIG. A display form in which the acceleration needles 82 shown in FIG. In this way, the current state of acceleration can be known by the movement of the acceleration needle 82, and the speed and acceleration conditions so far can be known from the acceleration graph 47 covering the speed graph 43, and the point display area 48 And various points displayed in the total point display area 49 can be known at the same time. Further, as can be seen by comparing FIG. 3 and FIG. 7, the display mode (arrangement, size, etc.) of each graph and numerical value can be freely set (note that the reference numerals in FIGS. 3 and 5 and FIG. 7). The corresponding reference numerals are attached).

  Further, as another eco-drive information display mode, as shown in FIG. 8, it may be performed by displaying a 3D object. In the standby screen 40 of FIG. 8, the acceleration needle 82, which is an analog needle meter, each drawn as a 3D object, the scale 102 provided at the location indicated by the acceleration needle 82, and the reduction provided on the left side of the analog needle meter. A deceleration digital meter 104b, which is a digital meter that displays the speed digitally, and an acceleration digital meter 104a, which is a digital meter that digitally displays the acceleration provided on the right side of the analog needle meter, are provided below these meter sections. A speed graph 43, a speed display area 50, a total point display area 49, a point display area 48, and the like are drawn. The acceleration needle 82 which is an analog needle meter is drawn so as to point directly below as shown in FIG. 8A when the acceleration is 0, and when the acceleration is positive (acceleration), the acceleration needle 82 shown in FIG. As shown in (), the image is drawn so as to move smoothly (analogly) to the right according to the magnitude of acceleration. Similarly, when the acceleration is negative (when decelerating), drawing is performed so that the left side moves smoothly (analogly) according to the magnitude of the deceleration.

  As shown in FIG. 8A, for these overlapping objects, at least a part of the overlapping objects is drawn and displayed as a transparent color object. That is, as shown in FIG. 8B, the inner area of the speed graph 43 is drawn with a semi-transparent color, and the speed graph 43 is drawn on the scale 102 so as to overlap. In this way, when a plurality of objects are displayed on the screen, the size of each object can be increased and the visibility of the display contents can be ensured. Can be easily obtained at the same time.

  Further, as shown in FIG. 8A, the scale 102 is configured by arranging spherical 3D objects on the circumference at predetermined intervals, and the color of each spherical 3D object is different for each zone. That is, when the acceleration is zero, a predetermined number of regions (examples in FIG. 8) are located on the left and right sides from the location pointed by the acceleration needle 82 (referred to as the origin, where the location indicated by the acceleration needle 82 in FIG. 8A corresponds to the origin). In FIG. 8, the left and right sides of the origin are blue), and a predetermined number of areas (5 in the example of FIG. 8) are yellow before, and further areas are red.

  The acceleration needle 82 indicates the range of the blue scale 102 when the acceleration is a value corresponding to the safety area, and indicates the range of the yellow scale 102 when the acceleration is a value corresponding to the attention area. When the value corresponds to the area, the value is displayed so as to indicate the range of the red scale 102. It should be noted that which region the acceleration is applied to may be adjusted by performing acceleration / deceleration in a state where the acceleration is mounted on an actual vehicle.

  Further, the same color as the scale of the zone indicated by the acceleration needle 82 is mixed with the background color and displayed as a gradation as the background color of the standby screen 40. That is, as shown in FIG. 8A, when the acceleration needle 82 points to the zone of the blue scale 102, the background color is a blue gradation display. On the other hand, as shown in FIG. 8B, when the acceleration needle 82 points to the zone of the yellow scale 102, the background color is a yellow gradation display. Similarly, when the acceleration needle 82 points to the zone of the red scale 102, the background color is displayed in red gradation.

  Further, the scale color of the zone indicated by the analog needle meter and the color of the digital meter are displayed in association with each other. In the present embodiment, the acceleration digital meter 104a and the deceleration digital meter 104b are drawn as a rectangular display area associated with the spherical 3D object of the scale 102. That is, the acceleration digital meter 104a and the deceleration digital meter 104b are each composed of 20 rectangular display areas, each of the five rectangles from the bottom blue, the five rectangles above it yellow, and the top 15 Each rectangle is used as a red display area. Then, as shown in FIG. 8A, when the acceleration is zero, the rectangles are not filled with these colors and are displayed in gray. On the other hand, as shown in FIG. 8B, when the acceleration needle 82 points to a scale other than 0, the corresponding rectangular area up to the position of the scale 102 is filled with the corresponding color. That is, as shown in FIG. 8B, when the acceleration needle 82 points to the third scale 102 from the bottom of yellow, five blue regions from the bottom and three yellow regions above the rectangular region Fill. In this way, a digital meter is displayed together with the analog needle meter, and the acceleration status is safe by displaying the scale color of the zone indicated by the analog needle meter in association with the color of the digital meter. It can be easily and intuitively known whether or not.

In addition, although the filling of the acceleration needle 82 and each rectangular area of the acceleration digital meter 104a and the deceleration digital meter 104b may be completely interlocked, the absolute value of acceleration is lower than the painted part after the filling. In such a case, after a predetermined time (for example, 1 second) has passed since the lowering, the drawing may be performed so as to return to the gray display in order from the rectangular region located above. In this way, when the acceleration fluctuates, the state of the peak value can be easily known from the acceleration digital meter 104a and the deceleration digital meter 104b. That is, the state of acceleration change can be found from the movement of the acceleration needle 82, and the state of maximum acceleration within a predetermined time can be seen from the display of the acceleration digital meter 104a and the deceleration digital meter 104b.
Further, each 3D object may be moved or a virtual camera that captures the 3D object may be moved according to the state of acceleration.

  It should be noted that at the start of displaying eco-drive information, animation display may be performed so that the 3D object enters the screen from outside the screen. For example, the 3D object and the camera position where the 3D object is photographed may be moved and drawn in the order shown in FIGS. In other words, a part of the scale 102 is enlarged and gradually reduced, and the overall point display area 49, the hourly speed display area 50, the graph display area 43, the acceleration digital meter 104a, and the deceleration digital meter 104b are slid in from the upper side. The point display area 48 is slid in from the right side. By doing so, it can be easily understood that the standby screen 40 has been switched to the display of eco-drive information.
