Description

The present invention relates to electronic devices and programs.

There is known an in-vehicle electronic device that evaluates how much an environment-friendly driver has driven according to the efforts of a user (eco-driving evaluation) and displays the evaluation contents in characters (Patent Document 1).

Japanese Unexamined Patent Publication No. 2005-016443

However, in such an in-vehicle electronic device, since the driver concentrates on driving, the driver rarely sees the display of the evaluation content, and it is not possible to naturally raise the driver's awareness of eco-driving. There was a problem.

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

Therefore, the present invention has been made to solve such a problem, and it is possible to raise the driver's awareness of eco-driving more naturally than before, and the driving operation to become eco-driving is sensuous and intuitive. The purpose is to provide electronic devices and programs that can be acquired by.

In order to achieve the above-mentioned object, the in-vehicle electronic device according to the present invention is (1) in an in-vehicle electronic device that displays a predetermined event occurrence screen when a predetermined event occurs, at least when the event occurrence screen is not displayed. A standby screen display means for displaying a standby screen, which is a screen to be displayed, is provided, and the standby screen display means is characterized in that it displays eco-driving information.

As the eco-driving information, for example, advice on eco-driving may be simply displayed (drawn). For example, "Are you checking the tire pressure?""Is there any unnecessary luggage left in the trunk?""Driving can reduce fuel consumption by planning." By doing this, eco-driving can be promoted.
Predetermined events include, for example, a radar approach warning in a radar detector and the like. Further, for example, intersection guidance in a navigation device and the like can be mentioned.

For example, normally, as a standby screen of a radar detector, a graph display screen, which will be described later, is displayed, and a target POI (point of interest) such as Orbis approaches at the time of radar wave reception alarm or at a predetermined distance. When a predetermined event such as time occurs, it is preferable to automatically switch to a predetermined event occurrence screen such as an alarm screen or a radar scope screen.

In this way, when an event occurs, information about the event can be obtained, 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 paid attention to by the user, the content of the standby screen is often naturally paid attention to 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, the eco-driving information by utilizing the attention to the event occurrence screen. Therefore, it is possible to raise the driver's awareness 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 finished, and to stop the output of the alarm sound when switching to the standby screen displaying the eco-driving information. .. In this way, it is possible to easily raise awareness of the driver regarding eco-driving.

(2) It is further preferable that the standby screen display means includes the drive state detecting means for detecting the drive state, and displays the eco-driving information based on the drive state detected by the drive state detecting means. For example, it is particularly preferable to change the content of the eco-driving information based on the drive state detected by the drive state detecting means.

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

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

If you follow the steps (3) and (4) above, you can see the state and change of velocity and acceleration just by looking at the 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, when sudden start, sudden acceleration, sudden braking, etc. are applied, a graph appears. In addition, the graph is displayed in a wavy manner when sudden start, sudden acceleration, sudden braking, etc. are repeated.
If this display unit is installed at a position where the driver can see it while driving, and the driver looks at it and drives so that the graph is as flat and gentle as possible, it becomes eco-driving.

For example, the first axis may be a horizontal axis and the second axis may be a vertical axis, or conversely, the first axis may be a vertical axis and the second axis may be a horizontal axis. Further, by arranging each axis at an angle rather than parallel to the top, bottom, left, and right sides of the screen, a pseudo three-dimensional display graph may be obtained.

(5) Further, the standby screen display means may display the economic running speed as the eco-driving information. As a display related to the economic driving speed, for example, when displaying the economic driving speed numerically or displaying the vehicle speed as a graph as shown in (3), a guideline is displayed at a position corresponding to the economic speed in the graph. It is good to do it (see (15) below).

In addition to the speed, it is advisable to display the guideline at the position corresponding to the value that becomes eco-driving on the graph. For example, a line of economic acceleration may be drawn in the acceleration graph (see (15) below).

In this way, it is possible to see at a glance how much the speed and acceleration of oneself deviates from the speed and acceleration of eco-driving. Therefore, eco-driving can be realized more easily.

(6) Further, the drive state detecting means includes an idling time detecting means for detecting the idling time of the engine, and the standby screen display means is the idling of the engine detected by the idling time detecting means as the eco-driving information. It is advisable to display the time. As the idling time detecting means, for example, it is preferable to detect the time when the speed of the vehicle detected by the speed detecting means is 0. Further, as the display regarding 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 representing the number of seconds of the idling time).

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

The drive state detecting means can also be configured as, for example, a means for detecting various information flowing on the in-vehicle LAN existing in the vehicle. Further, the drive state detecting means may be, for example, a temperature detecting means for detecting the temperature outside the vehicle. For example, if the temperature outside the vehicle is a predetermined temperature (in the temperature range where people feel comfortable without using the air conditioner), the indication that eco-driving is possible when the air conditioner is stopped is displayed as eco-driving information. It may be displayed. At this time, it may be determined whether or not this display is performed in consideration of the operating state of the air conditioner, the temperature inside the vehicle, and the like. Further, as the drive state detecting means, a means for detecting the engine speed, the vehicle vibration state, and the gear shift state may be used as described later.

Then, as the drive state detecting means, for example, various means described above can be used in combination. Further, for example, it may be decided whether or not to use the detection state of the other means based on the detection state of any of the various means described above.

(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 speed of the vehicle, and the standby screen display means detects by the vehicle speed detecting means. When the speed of the vehicle is less than a predetermined speed, the eco-driving information is displayed based on the engine speed detected by the engine speed detecting means, and the speed of the vehicle detected by the vehicle speed detecting means is displayed. When is equal to or higher than a predetermined speed, the eco-driving information may be displayed based on the speed of the vehicle detected by the vehicle speed detecting means. In this way, accurate eco-driving information can be provided even when the vehicle speed detecting means is configured by GPS or the like, which is difficult to obtain sufficient accuracy in a low speed state (a state of less than a predetermined speed). .. How to accelerate without depressing the accelerator at the start of the car has a great effect on eco. Therefore, with such a configuration, low-speed state detection can be performed with high accuracy, and a particularly excellent effect is exhibited. For example, if the speed is lower than the specified speed, the change in the engine speed is detected by the superimposed power supply noise, the eco-driving is judged, the eco-warning is issued, and the speed is measured by GPS. It is advisable to use GPS measurement data.
Further, for example, the standby screen display means may display the ratio of the speed to the engine speed as eco-driving information, or may be used for determining eco-driving.

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

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

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

(11) Further, the drive state detecting means includes a vehicle acceleration detecting means for detecting the acceleration of the vehicle, and the standby screen display means displays the acceleration of the vehicle detected by the vehicle acceleration detecting means as the eco-driving information. It is recommended to display with the inclination of a straight line. For example, if it is horizontal, the acceleration is zero, if it rises to the right, it is accelerating, if it falls to the right, it is decelerating, and if the angle is steeper, the acceleration may increase by drawing a straight line. For example, it may be displayed like an analog meter. As a result, the acceleration state can be known instantly. It is easier to understand by accelerating and decelerating, or by changing the color and thickness of the straight line within a predetermined acceleration range. The straight line may be overlaid on a graph displaying the history by speed and acceleration. In this case, it is easy to understand if it is displayed so as to be in contact with the current speed point (tangent line) of the graph.

(12) As the display mode of the eco-driving information, as described above, it can be displayed as a graph or numerically, but the drive can be displayed together with the eco-driving information or as the eco-driving information. The drive state detected by the state detecting means may be displayed in the form of an analog needle type meter. The analog needle type meter can intuitively judge the movement of tension, and you can learn eco-driving (eco-driving) without watching the meter. For example, it may be displayed as a sports meter-like ecometer.

(13) The analog needle type meter is provided with a scale at a position indicated by the analog needle type 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 type meter is displayed. It is preferable to display the color based on the above as the background color of the standby screen.

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

(15) Further, for example, the drive state detecting means includes a vehicle acceleration detecting means for detecting the acceleration of the vehicle, and the analog needle type meter is a vertical needle when the acceleration is 0. When accelerating, the needle may be tilted from the vertical direction to the right, and when decelerating, the needle may be tilted from the vertical direction to the left.

(16) Further, for example, the analog needle type meter may display a needle indicating the speed of the vehicle and a guide needle indicating the eco-speed. For example, the hand indicating the speed is moved clockwise according to the increase in the speed of the vehicle, and the hand indicating the speed is moved counterclockwise according to the decrease in the speed. It is advisable to display a guide needle indicating the eco-speed separately from the indicating needle. The guide needle (eco-speed display needle) is, for example, when it detects that the vehicle speed has changed from the state of 0 (for example, when it detects an acceleration of a predetermined value or more when the vehicle acceleration detecting means is provided), 5 It is moved to a speed of 60 km / h at a rate of 20 km / h in seconds, and when the vehicle speed runs at a constant speed for 5 seconds, it is moved so as to overlap with the needle (actual speed tension) indicating the speed. In this way, eco-driving can be performed simply by increasing the vehicle speed so as to follow the movement of the guide needle. It should be noted that the speed limit of the road currently traveling 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 based on the drive state detected by the drive state detection means and a display indicating an index of the eco-drive state. For example, as described above, it is preferable to display numerical values and lines of speed and acceleration in the eco-driving state in a graph or an analog needle type meter.

The eco-driving state means a driving state that becomes eco-driving. The eco-driving state is, for example, the recording of the driving state obtained by driving the vehicle while recording the driving state detected by the driving state detecting means and driving equivalent to the eco-driving, and the non-eco-driving driving (for example, economy). It is advisable to obtain it based on the difference from the drive state record obtained by traveling deviating from the traveling speed, sudden acceleration, sudden deceleration, etc.

(18) Further, the standby screen display means changes the display mode based on the drive state detected by the drive state detecting means as the eco-driving information based on the degree of coincidence between the drive state and the eco-driving state. Good.

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

Further, for example, the display mode may be changed based on the drive state by enlarging / reducing. For example, while displaying a graph, if it becomes a non-eco-driving state, it is advisable to enlarge the part of the graph. For example, the method of magnifying the display is to smoothly move the entire screen around the part and magnify it, or to display the picture of the magnifying glass and magnify the graph in the picture of the magnifying glass (non-eco-friendly points). ) It is advisable to take a mode of putting it in the center and expanding it. Also, after a certain period of time has passed, or when the eco-driving state is restored, the expansion is canceled. Release should be done smoothly. In addition, at the time of expansion, it is advisable to notify the alarm sound and the reason for expansion (reason for non-eco).

Further, the display mode may be changed based on the drive state by changing the character to be displayed. For example, if you do eco-driving (when the degree of agreement between the detected driving state and the eco-driving state is high), you may change the character so that the creature evolves, or if you do not eco-drive (detected) If the degree of agreement 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, not just by displaying points or displaying graphs. For example, the drive state may be detected by speed monitoring by GPS and sudden start or steering by an acceleration sensor. The evolution of living things is, for example, displaying an amoeber in the initial state, and in the case of eco-driving, it becomes a daphnia. Alternatively, you may want to be a cute girl or a good cat. On the other hand, if it is not eco-driving, you may try to become a dinosaur, a monkey, or a bad cat. In this way, you can enjoy eco-driving as if you were playing a game.
As described above, the display mode may be changed based on the drive state by at least one of color change, enlargement / reduction, and change of the character to be displayed.

(20) Further, the standby screen display means may calculate and display points as the eco-drive information based on the degree of coincidence between the drive state and the eco-drive state detected by the drive state detecting means. For example, it is advisable to increase the points when a drive state corresponding to eco-driving is detected, and to decrease points when a drive state contrary to eco-driving is detected. In this way, the driver can be motivated to drive toward eco-driving aiming at a high point.

(21) Further, when the degree of agreement between the drive state and the eco-drive state detected by the drive state detecting means is equal to or more than a predetermined value, it is preferable to notify the driver of the content to praise the driver. By "praising if you like" the driving condition, you will be able to enjoy eco-driving.

(22) Further, it is provided with a function of notifying when the degree of coincidence between the drive state and the eco-driving state detected by the drive state detecting means reaches a predetermined state, and the notification is during the event occurrence or the event occurrence. It is advisable not to do this in at least one of the cases within a predetermined time. For example, when the eco-driving state is lost (when the degree of matching is less than or equal to a predetermined value), a warning may be notified, or as shown in (21), the degree of matching between the driving state and the eco-driving state is predetermined. When the value is equal to or higher than the value, the content of complimenting the driver may be notified. Then, by not performing this notification during the event occurrence or within a predetermined time from the event occurrence, the notification when the event occurs (for example, when the event occurrence screen shown in (1) is displayed or the event occurrence is generated. It is possible to prevent the driver and the like from feeling annoyed by being notified when the degree of coincidence between the driving state and the eco-driving state becomes a predetermined state during or immediately after this notification (such as output of a notification sound). .. For example, when a sudden acceleration / deceleration is detected as a driving state, an eco-alarm is issued, but when a sudden deceleration is detected during an approach warning to the speed measuring device or within a predetermined time after the approach warning, a sudden deceleration is detected. Since it is a sudden deceleration due to approaching the speed measuring device, it is advisable not to give an eco-warning.

(23) Further, it is preferable to output the sound based on the drive state detected by the drive state detecting means. In particular, the sound output may be performed in proportion to the degree of disagreement between the drive state and the eco-drive state detected by the drive state detecting means. For example, in (11) to (14), when the speed or acceleration of the vehicle is displayed by the inclination of the line (needle), it is preferable to output the sound at the pitch or volume according to the magnitude of the inclination. For example, the greater the slope, the higher the pitch and the louder the volume. In this way, it is possible to intuitively understand how much the vehicle deviates from the eco-driving state by the pitch and loudness.

Further, as the sound output, for example, noise sound or the like accompanying the engine rotation may be acquired from a power supply line or the like, amplified, and output. In this way, it is possible to intuitively and intuitively learn the driving operation that is eco-driving and the driving operation that is not eco-driving from the loudness and pitch of the noise sound.

If the sound output is performed only when the degree of mismatch between the drive state and the eco-drive state detected by the drive state detecting means exceeds a predetermined degree of mismatch, the sound can be output without looking at the standby screen. You can tell whether you are in an eco-driving state by the presence or absence of. In addition, it is possible to reduce the annoyance of the user.
(24) The standby screen display means may display the eco-driving information by displaying a 3D object.

(25) At the start of displaying the eco-driving information, it is preferable to perform an animation display so that the 3D object enters the screen from outside the screen.

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

According to the present invention, it is possible to provide an electronic device that can raise the driver's awareness of eco-driving more naturally than before and can intuitively and intuitively acquire the driving operation that becomes eco-driving. Can be done.

1 and 2 show the configuration of a radar detector, which is an embodiment suitable for the in-vehicle electronic device of 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 surface side of the case body 1, and the display unit 5 is arranged on the rear surface of the case body 1. And an alarm lamp 6 and an infrared communication device 7. Further, the GPS receiver 8 is arranged inside the upper surface side of the case body 1. Further, an adapter jack 9 is arranged on one side surface of the case body 1, and a power switch 10 and a DC jack 11 are arranged on the other side surface. In addition, 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 (particularly, the height direction is widened). Along with this, 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, a display unit 5 having a larger screen than the conventional one can be provided.

As shown in FIG. 2, the infrared communication device 7 transmits / receives data to / from a communication device having 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, the data stored in the memory card 14 mounted on the memory card reader 13 can be taken in inside. More specifically, the data stored in the memory card 14 includes update information such as new target information (position information including longitude / latitude, type information, etc.), and the update information is transmitted via the control unit 18. It is stored (downloaded) in the database 19 built in the device and the data is updated. The database 19 can be realized by a non-volatile memory (for example, EEPROM) inside the microcomputer of the control unit 18 or externally attached to the microcomputer. Information about a certain target object is registered in the database 19 at the time of shipment, and data and the like about the target object added after that are updated as described above. Further, the data can be updated 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 a vehicle via the cigar plug cord so that power can be supplied. Further, the radar detector of the present embodiment includes a wireless receiver 15 and a remote control receiver 16. The radio receiver 15 receives the incoming radio of a predetermined frequency. The remote controller receiver 16 communicates data with the remote controller (portable device: slave unit) 17 and makes various settings for the device. Further, the switch unit 3 is also connected to the control unit 18 (not shown) so that the same settings as the remote controller 17 can be performed.

Further, the control unit 18 executes a predetermined process based on the information input from the various input devices (GPS receiver 8, microwave receiver 4, 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.). It should be noted that these basic configurations can basically be the same as those of the conventional ones.

The function of the radar detector of the present embodiment is realized by being stored in 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 having the control unit 18.

FIG. 3 is a diagram showing 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. Further, FIG. 4 is a diagram showing an alarm screen 60 as an event generation 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 from the GPS receiver 8 every second, and as a predetermined event, the current position is the position of the target and the predetermined position stored in the database 19. When the distance is (for example, 1 km or less), an approach warning to the target object is output from the speaker 20, and the warning screen 60 is displayed on the display unit 5.

When the microwave receiver 4 receives the microwave emitted by the speed measuring device as a predetermined event, the alarm screen of the microwave reception alarm is displayed as the 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 an 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, the process of drawing the standby screen 40 is performed. That is, the radar detector of the present embodiment starts 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 row, a point and graph display area in the middle row, and a total point / time / speed display area in the lower row. In the icon display area 41, an icon indicating the current setting state (for example, various modes) and information on the traveling location (for example, whether it is a parking prohibition monitoring area) is displayed as in the conventional radar detector.
The point and graph display areas have a point display area on the left side and a graph display area on the right side.

The graph display area is an area in which the speed graph 43 is drawn in the upper row and the acceleration graph 47 is drawn in the lower row. The speed graph 43 is a graph showing speed in the vertical direction and time in the horizontal direction, 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 by the size of a bar (line in the vertical direction). That is, when the power is turned on, the drawing of the bar is started from the position on the right side in contact with the vertical axis 46, and the next bar is drawn at the position adjacent to the previously drawn bar. In this way, the 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 completed, the first drawn bar is erased, the bar is moved to the left by one bar, and then the bar is drawn. In this way, the graph is subsequently drawn while scrolling. Regarding the size of the bar, the size of the bar is set to 0 at 0 km / h, the drawing is drawn at a speed of 60 km / h up to the position of the economic speed reference line 44, and the vertical axis is 46 at 110 km / h. Draw in a size that reaches the same height as the top edge. When the speed exceeds 110 km / h, the drawing is performed in a size similar to that of the upper end of the vertical axis 46. Further, the acceleration is calculated based on the history of the speed information acquired from the GPS receiver 8. Of course, an acceleration sensor or the like may be independently mounted, and the value of the acceleration sensor may be read from the control unit 18 to calculate the acceleration. The acceleration graph 47 is a graph showing acceleration in the vertical direction and time in the horizontal direction, and has a vertical axis 46, a horizontal axis 42, and a line 45 having zero acceleration. In the present embodiment, the velocity graph 43 and the acceleration graph 17 use the vertical axis 46 and the horizontal axis 42 in common, but of course, the axes may be displayed separately. Further, in that case, the line 45 having zero acceleration 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 by the size of a bar (line in the vertical direction). That is, when the obtained acceleration indicates acceleration, a bar corresponding to the magnitude of acceleration is drawn above the line 45 of 0 acceleration, and when indicating deceleration, the acceleration is below the line 45 of 0 acceleration. Draw a bar according to the size of. In addition, the method of drawing the bar is the same as that of the speed graph 43 described above.

The point display area has, in order from the top, a point display area 48a for sudden acceleration, a point display area 48b for sudden deceleration, a point display area 48c for idling time, and a point display area 48d for economic running speed. In each point display area 48 (48a to 48d), the initial value is 70, the maximum value is 100, the minimum value is 0, and when the state corresponding to eco-driving continues for a predetermined time, +1 (additional points) and eco-driving This is an area where the result of -1 (point deduction) is displayed numerically when the state that does not correspond to is continued for a predetermined time. That is, the point of sudden acceleration is deducted when it is judged that the acceleration corresponds to the sudden acceleration, the point of sudden deceleration is deducted when it is judged that it is sudden deceleration due to sudden braking, etc., and the point of idling time is after the engine is started. If the stopped time exceeds a predetermined time (for example, 2 minutes), points will be deducted every predetermined time (for example, 1 minute), and the points of economic driving speed will be from 60 km / h to a predetermined range (for example, 60 / h plus). Points will be deducted if the vehicle is not running in the range of -5 km / h for a predetermined time (for example, 5 minutes). For each point, if a state other than the above continues for a predetermined time (for example, 2 minutes), each point is added. The state in which points are deducted or added may be determined based on the actual measurement results by creating a non-eco-driving state. The idling time may be detected when the speed acquired from the GPS receiver 8 is 0.

In the lower overall point display area 49, the average value of each point displayed in the sudden acceleration point display area 48a, the sudden deceleration point display area 48b, the idling time point display area 48c, and the economic running speed point display area 48d. Is displayed.
Further, 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 when a predetermined event occurs, that is, whether, for example, the current position is at a predetermined distance (for example, 1 km or less) from the position of the target object stored in the database 19. When it is determined that the above is true, an approach warning to the target object is output from the speaker 20, and the warning screen 60 shown in FIG. 4 is displayed on the display unit 5 as an event occurrence 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 warning screen 60 has a distance display area 66 from the alarm object in the upper right side, a radar scope display area 67 in the middle right side that displays the relationship between the position 67a of the alarm object and the vehicle position 67b as a bird's-eye view, and a lower right side. It has a time display area 68 for displaying the current time acquired from the GPS receiver 8.

The control unit 18 determines whether or not the current position acquired from the GPS receiver 8 is substantially the same as the position of the target object stored in the database 19 (for example, the distance between the two is 10 m or less). When it is determined, the speaker 20 outputs a sound to the effect that the approach warning to the target object is terminated. That is, the control unit 18 outputs a voice saying, for example, "passes the position of the speed measuring device". After the audio output, the control unit 18 performs display processing on the standby screen 40 on the display unit 5.

In this way, when an alarm is generated, information about the alarm can be obtained, but in the standby state where the alarm is not generated, eco-driving information is displayed as a graph or a point on the standby screen 40. You can be aware of eco-driving on a daily basis.

In particular, since the alarm screen 60 is often paid attention to by the user, the content of the standby screen 40 is often naturally paid attention to when switching from the alarm screen 60 to the standby screen 40. Therefore, by utilizing the attention to the alarm screen 60, it is possible to deeply impress the contents of the standby screen 40, that is, the eco-driving information. Therefore, it is possible to raise the driver's awareness of eco-driving more naturally than before. In particular, since the voice is output when the display of the alarm screen 60 is terminated, it is possible to efficiently and effectively raise the awareness of the driver regarding eco-driving.

In addition, eco-driving information changes graphs and points over time. If the driver looks at the display unit 5 and drives while the vehicle is stopped so that each point is high so that the graph is as flat and gentle as possible, eco-driving is achieved.

In this embodiment, the time axis is taken in the horizontal direction and the physical quantity of velocity / acceleration is taken in the vertical direction for drawing. For example, the time axis is taken in the vertical direction and the physical quantity of velocity / acceleration is taken in the horizontal direction. It may be taken and drawn.

Since the economic speed reference line 44, which serves as a guideline, is displayed at the position corresponding to the economic speed, you can see at a glance how much your speed deviated from the speed and acceleration of eco-driving, and when it deviated. I understand. Therefore, it is possible to determine 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 point display area 48c of the idling time. For example, "idling time n seconds" (n is the seconds of the idling time) on the standby screen 40. It may be displayed as a numerical value, such as (a numerical value representing a number).

In this embodiment, the GPS receiver 8 is used for speed detection, but when speed measurement is performed by GPS, there is a problem that it is difficult to measure a stop or low speed running. Therefore, it is advisable to use the engine speed. As a method of detecting the engine speed, for example, a method of detecting the engine speed from the alternator noise or the ignition noise superimposed on the power supply line of the car may be used. For example, when power is supplied from the DC jack 11, the power is supplied from the cigar socket of the vehicle via the cigar plug cord, so that the alternator noise of this power supply or the ignition noise is the engine speed. It is good to detect. As this method, various known methods can be used.

If the speed of the vehicle detected by the GPS receiver 8 is less than the predetermined speed, eco-driving information is displayed based on the engine speed, and the speed of the vehicle detected by the GPS receiver 8 is the predetermined speed. In the above case, it is preferable to display the graph and points of FIG. 3 based on the speed of the vehicle detected by the GPS receiver 8.

In this way, even when the vehicle speed detecting means is configured by the GPS receiver 8 in a low speed state (a state of less than a predetermined speed) and it is difficult to obtain sufficient accuracy, accurate graphs and points can be obtained. Can be provided. How to accelerate without depressing the accelerator at the start of the car has a great effect on eco. Therefore, with such a configuration, low-speed state detection can be performed with high accuracy, and a particularly excellent effect is exhibited. Further, for example, the standby screen 40 may further display the ratio of the speed and the engine speed as eco-driving information.

In addition, for example, it may be configured to detect various information flowing on the in-vehicle LAN existing in the vehicle. Further, for example, a temperature sensor for detecting the temperature outside the vehicle is connected to the control unit 18, and for example, the temperature outside the vehicle is a predetermined temperature (in a temperature range in which a person feels comfortable without using an air conditioner). In this case, a display indicating that eco-driving can be performed 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 or not this display is performed in consideration of the operating state of the air conditioner, the temperature inside 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 vehicle vibration in place of the engine speed or together with the engine speed is connected to the control unit 18, and the standby screen 40 shows 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 for detecting the engine speed from the vibration.

Further, the gear shift state detector for detecting 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, if the gear shift state is in the neutral or parking state, the speed is 0, and vibration is detected by the vibration sensor, it is determined to be in the idling state, and if this state continues for 1 minute or more, the idling time point. It is recommended to subtract and display. As the gear shift detector, for example, a sensor for detecting the 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. Further, the standby screen 40 may also display the engine speed as eco-driving information.

Further, on the standby screen 40, the acceleration of the vehicle may be displayed as the inclination of a straight line as eco-driving 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 tangent to the right end (that is, the latest speed) point of the speed graph 43. In this way, for example, if it is horizontal, the current acceleration is zero, if it rises to the right, it is currently accelerating, if it falls to the right, it is currently decelerating, and the steeper the angle, the greater the acceleration. As a result, the acceleration state can be instantly known. It is easier to understand by accelerating and decelerating, or by changing the color and thickness of the straight line within a predetermined acceleration range.

As described above, the eco-driving information can be displayed in a graph or numerically, but the speed and acceleration can be displayed together with the eco-driving information or as the eco-driving information by analog needle type. It may be displayed in the form of a meter. The analog needle type meter can intuitively judge the movement of tension, and you can learn eco-driving (eco-driving) without watching 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. The standby screen 40 displays the analog needle type accelerometer 80 on the left side. In the analog needle type acceleration meter 80, as eco-driving 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 sudden deceleration guideline 83 which is an index of the eco-driving state is displayed. The sudden acceleration guideline 84 is displayed. When the acceleration is 0, it is displayed as a vertical acceleration needle 82 as shown in FIG. 5, the acceleration needle 82 is tilted to the right as shown in FIG. 6 when accelerating, and the acceleration needle 82 is tilted to the left when decelerating. Display so that 82 is tilted. The sudden deceleration guideline 83 is displayed at the boundary position between the normal deceleration state and the sudden deceleration state that does not result in eco-driving, and the sudden acceleration guideline 84 indicates the boundary position between the normal acceleration state and the sudden acceleration state that does not result in eco-driving. It is displayed in. To determine the position to display the sudden deceleration guideline 83 and the sudden acceleration guideline 84, the appropriate position should be determined by performing sudden deceleration / acceleration with the radar detector mounted on the actual vehicle. ..

Further, as shown in FIGS. 5 and 6, the standby screen 40 displays the analog needle type speedometer 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 an eco speed, and a minimum value (for example, 80 km / h) of an economic speed when traveling on a highway. The high-speed running economic speed minimum value guideline 94a and the high-speed running economic speed maximum value guideline 94b indicating the maximum value of the economic speed when driving 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 is displayed to move clockwise as the speed of the vehicle increases, and to move counterclockwise as the speed decreases. Further, the analog needle type speedometer 90 displays an eco-speed guide needle 92 indicating an eco-speed separately from the speed hand 93.

When the eco-speed guide needle 92 detects that the speed acquired from the GPS receiver 8 has changed from the state of 0, the eco-speed guide needle 92 moves the speed up to 60 km / h at a rate of 20 km / h in 5 seconds. At this time, the eco-speed guide needle 92 may be drawn so that the instructed speed increases smoothly (gradually). The eco-speed guide needle 92 serves as an index for eco-driving, especially when starting. That is, when the speed needle 93 increases faster than the degree of increase of the eco-speed guide needle 92 (the actual acceleration of the vehicle speed is large), it is estimated that the vehicle starts suddenly and is not in the eco-driving state. it can. Therefore, it can be understood that the driver should drive (step on the accelerator) so that the current speed of the vehicle (the speed indicated by the speed hand 93) is slower or about the same as that of the eco-speed guide needle 92.

In addition, as one of the eco-driving, the vehicle may run 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 it is also in the eco-driving state. Therefore, the eco-speed guide needle 92 is moved so as to overlap the speed needle 93. .. As a result, 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 accelerates on the road. There is a risk of repeated acceleration and deceleration, such as deceleration without being able to maintain 60 km / h due to traffic conditions, etc., but when traveling at a constant speed, it is stable at a 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), so the current constant speed (speed indicated by the speed hand 93) and the eco-speed guide needle 92 are superimposed and drawn. By doing so, constant speed driving can be promoted.

Further, even if the speed of constant speed traveling exceeds 60 km / h, there is a possibility that the vehicle is traveling on an expressway, for example. Therefore, when traveling at a constant speed, the speed needle 93 and the eco-speed guide needle 92 may be traveling. And draw on top of each other.

The maximum speed indicated by the eco-speed guide needle 92 may be set, and when the vehicle is traveling at the maximum speed or higher, 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 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. 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 different depending on the type of road.

In FIG. 5, since the speed acquired from the GPS receiver 8 is 0 km / h, the speed hand 93 points to 0 km / h, and the eco-speed guide needle 92 also points to 0 km / h. Therefore, both are displayed overlapping. In FIG. 6, since the speed acquired from the GPS receiver 8 is 34 km / h, the speed hand 93 points to 34 km / h, and the eco-speed guide needle 92 changes from the state where the speed acquired from the GPS receiver 8 is 0. It is in a state 5 seconds after the detection of, and indicates a speed of 20 km / h. In the state of FIG. 6, since the eco-speed guide hand 92 is in the counterclockwise direction (leftward) of the speed hand 93, it can be seen at a glance that the speed is too high (sudden start). Further, in the state of FIG. 6, the acceleration needle 82 of the analog needle type acceleration meter 80 is on the right side of the sudden acceleration guideline 84, and it can be seen at a glance that it is in the sudden acceleration state.

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

The eco-speed guide needle 92 was moved up to 60 km / h. For example, the position and the 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. The eco-speed guide needle 92 may be moved to the acquired speed limit by acquiring the speed limit of the current traveling location from the position stored in.

Further, the display mode of the standby screen 40 as eco-driving information may be changed based on the degree of coincidence between the driving state and the eco-driving state. For example, the display mode may be changed by changing the color. For example, it is preferable to change the display color of the speed obtained from the GPS receiver 8 displayed in the speed display area 50 depending on whether or not it is eco-driving. For example, if the speed is in the range of 60 km / h plus or minus 10 km / h, the color may be green, and if the speed is other than that, the speed may be 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 they are eco-driving.

Further, for example, during graph display, if the state is not eco-driving, the graph portion may be enlarged and displayed. For example, the method of magnifying the display is to smoothly move the entire screen around the part and magnify it, or to display the picture of the magnifying glass and enlarge the graph in the picture of the magnifying glass (eco). It is good to magnify it by putting it in the center. Also, after a certain period of time has passed, or when the eco-driving state is restored, the expansion is canceled. Release should be done smoothly. In addition, at the time of expansion, it is advisable to notify the alarm sound and the reason for expansion (reason for non-eco).

Further, for example, when a character is displayed on the standby screen 40 and eco-driving is performed (when the detected speed is in the range of economic running speed (for example, 60 km / h) and plus or minus 10 km / h), the organism evolves. If you do not eco-drive (when the detected speed is not in the range of economic running speed (for example, 60 km / h) and plus or minus 10 km / h), the creature will be degenerated. May be displayed so as to change the character. That is, it is possible to learn eco-driving while having fun by changing the character to be displayed, not just by displaying points or displaying graphs. The evolution of living things is, for example, displaying an amoeber in the initial state, and in the case of eco-driving, it becomes a daphnia. Alternatively, you may want to be a cute girl or a good cat. On the other hand, if it is not eco-driving, you may try to become a dinosaur, a monkey, or a bad cat. In this way, you can enjoy eco-driving as if you were playing a game.

In addition, when the total points exceed 90 points, it is advisable to notify the driver of the content of praise. By "praising if you like," you will be able to enjoy eco-driving while having fun.

Further, for example, the acceleration is obtained based on the speed history acquired from the GPS receiver 8, and when the acceleration corresponding to the sudden acceleration / deceleration is obtained, the speaker 20 gives a voice eco-alarm for the sudden acceleration / deceleration. It may be notified. For example, an eco-warning is announced by voice such as "sudden acceleration" or "sudden 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. By doing so, if a sudden deceleration is detected during the approach warning to the speed measuring device or within a predetermined time after the approach warning, the eco-warning is given because the sudden deceleration is due to the approach to the speed measuring device. It disappears and the user does not feel annoyed.

Further, when an acceleration corresponding to sudden acceleration / deceleration is obtained, that is, when the acceleration needle 82 exceeds the sudden acceleration guideline 84 and is further to the right as shown in FIG. 6, the inclination thereof is increased. Outputs sound at the appropriate pitch and volume. For example, the greater the slope, the higher the pitch and the louder the volume. In this way, it is possible to intuitively understand how much the vehicle deviates from the eco-driving state by the pitch and loudness. In addition, since the relationship between the acceleration needle 82 displayed on the standby screen 40 and the sudden acceleration guideline 84 and the relationship between the pitch and the volume can be learned, the acceleration needle 82 can be adjusted according to the pitch and volume without paying attention to the acceleration needle 82. You can imagine the position and learn eco-driving more intuitively. When the acceleration of the vehicle is displayed as the inclination of a straight line as the eco-driving information, it is preferable to output the sound at the pitch and volume according to the magnitude of the inclination.

Further, when the power is supplied from the DC jack 11, the power is supplied from the cigar socket of the vehicle via the cigar plug cord, so that the alternator noise sound of this power supply is amplified and output as sound. You may do so. In this way, the relationship between the engine state and eco-driving can be known from the loudness and pitch of the noise sound, and the driving operation that is eco-driving and the driving operation that is not eco-driving can be sensuously determined by the sound state.・ You can learn intuitively.

According to the radar detector of each embodiment as described above, it is possible to raise the driver's awareness of eco-driving more naturally than before, and to acquire the driving operation that becomes eco-driving sensuously and intuitively. be able to.

The display mode of the eco-driving information is not limited to these, and various modes can be adopted. For example, as shown in FIG. 7, on the graphs (speed graph 43, acceleration graph 47) and numerical values (point display area 48, total point display area 49, numerical values displayed in the speed display area 50) shown in FIG. A display mode in which the acceleration hands 82 shown in FIG. 5 are superimposed and displayed may be adopted. In this way, the current state of acceleration can be known from the movement of the acceleration needle 82, and the state of speed and acceleration up to now can be known from the acceleration graph 47 over the speed graph 43, and the point display area 48 And various points displayed in the total point display area 49 can also be known at the same time. Further, as can be seen by comparing FIGS. 3 and 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 code of) has a corresponding code).

Further, as another display mode of the eco-driving information, as shown in FIG. 8, the display of the 3D object may be performed. On the standby screen 40 of FIG. 8, the acceleration needle 82, which is an analog needle type meter, drawn as a 3D object, the scale 102 provided at the point indicated by the acceleration needle 82, and the reduction provided on the left side of the analog needle type meter, respectively. The deceleration digital meter 104b, which is a digital meter that digitally displays the speed, the acceleration digital meter 104a, which is a digital meter that digitally displays the acceleration provided on the right side of the analog needle meter, and the acceleration digital meter 104a provided under these meters. The speed graph 43, the speed display area 50, the total point display area 49, the point display area 48, and the like are drawn. The acceleration needle 82, which is an analog needle type 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), FIG. 8B ), Draw to the right so that it moves smoothly (analog) according to the magnitude of acceleration. Similarly, when the acceleration is negative (during deceleration), the drawing is drawn to the left side so as to move smoothly (analog type) according to the magnitude of deceleration.

As shown in FIG. 8A, with respect to the overlapping objects among these 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 internal region of the speed graph 43 is drawn in a semi-transparent color, and the speed graph 43 is overlaid on the scale 102. By doing so, when a plurality of objects are displayed on the screen, the size of each object can be increased, the visibility of the displayed contents can be ensured, and a plurality of eco-driving information can be obtained. 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 0, a predetermined number of regions (referred to as the origin; the portion pointed by the acceleration needle 82 in FIG. 8A corresponds to the origin) to the left and right (example of FIG. 8) Then, 5 areas on both the left and right sides from the origin are blue, a predetermined number of areas (5 areas in the example of FIG. 8) are yellow, and the areas beyond that are red.

The acceleration needle 82 points to the range of the blue scale 102 when the acceleration is in the safe area, and points to the range of the yellow scale 102 when the acceleration is in the caution area, and the acceleration is dangerous. When the value corresponds to the area, it is displayed so as to indicate the range of the red scale 102. It is advisable to adjust which region the acceleration hits by accelerating or decelerating while mounted on an actual vehicle.

Further, the same color as the scale color of the zone pointed to by the acceleration needle 82 is mixed with the background color and displayed in gradation as the background color of the standby screen 40. That is, as shown in FIG. 8A, when the acceleration hand 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 hand 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 a red gradation display.

Furthermore, the color of the zone scale indicated by the analog needle type meter is displayed in association with the color of the digital type meter. In the present embodiment, the acceleration digital meter 104a and the deceleration digital meter 104b are drawn as a rectangular display area associated with a spherical 3D object on the scale 102. That is, the acceleration digital meter 104a and the deceleration digital meter 104b each consist of 20 rectangular display areas, each of which has five rectangles from the bottom in blue, five rectangles above it in yellow, and 15 above them. The rectangles are the red display area. Then, as shown in FIG. 8A, when the acceleration is 0, each rectangle is not filled with these colors and is displayed in gray. On the other hand, as shown in FIG. 8B, when the acceleration needle 82 points to a scale 102 other than 0, the rectangular area corresponding 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, the rectangular region has five blue regions from the bottom and three yellow regions above it. Fill. In this way, the digital meter is displayed together with the analog needle meter, and the color of the zone scale indicated by the analog needle meter is displayed in association with the color of the digital meter, so that the state of acceleration is safe. It is possible to easily and intuitively know whether or not it is.

The acceleration needle 82 and the filling of each rectangular area of the acceleration digital meter 104a and the deceleration digital meter 104b may be completely linked, but after the filling, the absolute value of the acceleration is lower than that of the filled portion. In this case, it is advisable to draw so as to return to the gray display in order from the rectangular area located above after a predetermined time (for example, 1 second) has elapsed from the lowering. 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 change in acceleration can be known from the movement of the acceleration needle 82, and the state of maximum acceleration within a predetermined time can be known from the displays of the acceleration digital meter 104a and the deceleration digital meter 104b.
Further, each 3D object may be moved or a virtual camera for photographing the 3D object may be moved according to the state of acceleration.

At the start of displaying the eco-driving information, it is advisable to perform an animation display so that the 3D object enters the screen from outside the screen. For example, the 3D object and the camera position for shooting the 3D object may be moved and drawn in the order shown in FIGS. 9 to 12. That is, while a part of the scale 102 is enlarged and gradually reduced, the total point display area 49, the speed display area 50, the graph display area 43, the acceleration digital meter 104a, and the deceleration digital meter 104b are slid in from above. While doing so, slide in the point display area 48 from the right side. By doing so, it can be easily seen that the standby screen 40 has been switched to the display of eco-driving information.
