Description

  The present invention relates to an electronic device and a program.

  There is known an on-vehicle electronic device that evaluates how environmentally friendly the driver has been driving according to the user's effort (eco-drive evaluation), and displays the content of the evaluation in characters (Patent Document 1).

JP, 2005-016443, A

However, in such an on-vehicle electronic device, since the driver concentrates on driving, the driver hardly sees the display of the evaluation content, and it is not possible to naturally make the driver aware of the eco-drive There was a problem that.

Further, when displaying the contents of evaluation in characters, there is a problem that the driver needs to read the characters, and it is difficult to intuitively and intuitively acquire the driving operation to be an eco-drive.

Therefore, the present invention has been made to solve such a problem, and the driver can be made more conscious of eco-drive more naturally than before, and the driving operation to be eco-drive is sensuous and intuitive. To provide electronic devices and programs that can be acquired.

  In order to achieve the above-described object, the on-vehicle electronic device according to the present invention is (1) a vehicle-mounted 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 by displaying eco-drive information.

As eco-drive information, for example, advice (eco-drive) related to eco-drive may be displayed (drawn). For example, "Are you checking the tire pressure?""Are you leaving unnecessary luggage in the trunk?""The drive will save you fuel if you plan." Can promote eco-driving.
As a predetermined event, for example, a radar approach warning in a radar detector, etc. may be mentioned. Another example is intersection guidance in a navigation device.

  For example, a graph display screen to 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 Orbis approaches a radar wave reception alarm or a predetermined distance. When a predetermined event such as time occurs, it may be automatically switched to a predetermined event generation screen such as an alarm screen or a radar scope screen.

In this way, when an event occurs, it is possible to obtain information about the event, while in a standby state where no event has occurred, eco-drive information is displayed, so eco-drive can be noticed from a day by day . In particular, since the user often pays attention to the event generation screen, the content of the standby screen may naturally be taken care of when switching from the event generation screen to the standby screen. Therefore, it is possible to make a deep impression on the contents of the standby screen, that is, the eco-drive information, by using the attention to the event occurrence screen. Therefore, it is possible to make the driver conscious about eco-driving more naturally than before. In particular, it is preferable to output a sound (for example, an alarm sound according to the event) until the display of the event generation screen is ended, and to end the output of the alarm sound when switching to a standby screen displaying ecodrive information. . In this way, it is possible to easily make the driver aware of eco-driving.

  (2) It is further preferable to include drive state detection means for detecting a drive state, and the standby screen display means display eco-drive information based on the drive state detected by the drive state detection means. For example, it is particularly preferable to change the content of the eco-drive information 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 speed of the vehicle, and the first axis is detected by the time axis and the second axis is detected by the vehicle speed detection means as the ecodrive information. It is recommended to include a graph of the speed of the vehicle being

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

According to the above (3) and (4), the state and change of the velocity and the acceleration can be known only by looking at the graph. For example, a bar graph (or line graph) in which the horizontal axis is a time axis and the vertical axis is a speed is displayed on the liquid crystal screen. The flatter the graph, the better the fuel consumption. On the other hand, the graph stands up when applying sudden start, sudden acceleration, sudden braking, etc. Also, when the sudden start, the rapid acceleration, the sudden braking, etc. are repeated, the graph is displayed as being waved.
This display unit is placed at a position where the driver can see while driving, and if the driver looks at it and drives so as to make the graph as flat and as smooth as possible, it becomes eco-drive.

For example, the first axis may be the horizontal axis and the second axis may be the vertical axis, or conversely, the first axis may be the vertical axis and the second axis may be the horizontal axis. In addition, the respective axes may be arranged in an inclined manner without being parallel to the upper, lower, left, and right sides of the screen, so that a graph of pseudo three-dimensional display may be obtained.

  (5) Further, the standby screen display means may display as the eco-drive information the economic traveling speed. For example, the economic traveling speed is displayed numerically as a display related to the economic traveling speed, or when displaying the vehicle speed graphically as shown in (3), a guideline is displayed at a position corresponding to the economic speed in the graph. You should do (see (15) below).

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

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

  (6) Further, the drive condition detection means includes idling time detection means for detecting an idling time of the engine, and the idle screen display means is an idling of the engine detected by the idling time detection means as the ecodrive information. It is good to display the time. As the idling time detection means, for example, it is preferable to detect a time during which the speed of the vehicle detected by the speed detection means is zero. Further, as a display related to the idling time, for example, the idling time may be displayed numerically as "idling time n seconds" (n is a numerical value representing the number of seconds of the idling time).

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

The drive state detection means can also 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, for example, a temperature detection means for detecting the temperature outside the vehicle. For example, when the temperature outside the vehicle is a predetermined temperature (within a temperature range where people feel comfortable without using the air conditioner), displaying that eco-driving can be performed by stopping the air conditioner is used as eco-drive information. It may be displayed. At this time, whether the display is to be performed may be determined in consideration of the operating state of the air conditioner, the temperature in the vehicle, and the like. Further, as the drive state detection means, means for detecting an engine rotational speed, a vehicle vibration state, and a gear shift state may be used as described later.

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

(8) For example, the drive state detecting means includes an engine rotational speed detecting means for detecting an engine rotational speed and a vehicle speed detecting means for detecting the speed of the vehicle, and the idle screen display means is detected by the vehicle speed detecting means If the speed of the determined vehicle is less than a predetermined speed, the eco-drive information is displayed based on the engine rotational speed detected by the engine rotational speed detection means, and the speed of the vehicle detected by the vehicle speed detection means If the vehicle speed is equal to or higher than a predetermined speed, the eco-drive information may be displayed based on the speed of the vehicle detected by the vehicle speed detection means. In this way, accurate eco-drive information can be provided even when the vehicle speed detection means is configured by a GPS or the like which is difficult to obtain sufficient accuracy in a low speed state (state less than a predetermined speed). . How to accelerate without depressing the accelerator at the time of the start of the car greatly affects the eco. 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, if the speed is lower than a predetermined speed, the change in engine speed is detected by the superimposed power supply noise, the eco-driving judgment or the eco-alarm is issued, and the GPS is measured by GPS or higher. You should use GPS measurement data.
Further, for example, the standby screen display means may display the ratio of the speed and the number of revolutions of the engine as eco-drive information or may use it for determination of eco-drive.

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

  (10) Further, the drive state detection means includes gear shift state detection means for detecting a gear shift state, and the standby screen display means displays the eco-drive information based on the gear shift state detected by the gear shift state detection means. You may do so. 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. Also, the gear shift state may be detected from the speed data by GPS and the engine speed.

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

  (11) In addition, the drive condition detection means includes vehicle acceleration detection means for detecting the acceleration of the vehicle, and the standby screen display means uses the acceleration of the vehicle detected by the vehicle acceleration detection means as the ecodrive information. It is good to display by the inclination of a straight line. For example, it is preferable to draw and display a straight line such that the acceleration is zero if it is horizontal, during acceleration when it is rising to the right, and during deceleration when it is falling to the right. For example, it may be displayed like an analog meter. This makes it possible to instantly know the state of acceleration. Further, it is easier to understand if the color and thickness of a straight line are changed within acceleration and deceleration or within a predetermined acceleration range. The straight line may be displayed superimposed on a graph displaying a history by speed and acceleration. In this case, it is easy to understand if the graph is displayed tangent to the current speed point.

  (12) As described above, the display mode of the eco-drive information can be displayed as a graph or a numerical value, but the drive may be displayed together with the eco-drive information or as the eco-drive information. The drive status detected by the status detection means may be displayed in the form of an analog needle meter. The analog needle type meter can sense the movement of the touch sensuously, and can learn eco driving (eco driving) without looking at the meter. For example, it is good to display as a sports meter style eco meter.

  (13) The analog needle type meter is provided with a scale at a position indicated by the analog needle type meter, and the scale is displayed in different colors for each predetermined zone, and the color of the scale of the zone indicated by the analog needle type meter Is preferably displayed 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 Each zone may be displayed in a different color, and the color of the scale of the zone indicated by the analog needle meter may be associated with the color of the digital meter.

  (15) Further, for example, a vehicle acceleration detection means for detecting the acceleration of the vehicle is provided as the drive state detection means, and the analog needle type meter is a needle in the vertical direction when the acceleration is zero. At the time of acceleration, the needle may be inclined from the vertical direction to the right, and at the time of deceleration, the needle may be displayed to be inclined from the vertical to the left.

  (16) Also, for example, the analog needle meter may display a needle that indicates the speed of the vehicle and a guide needle that indicates the eco-speed. For example, an indication is made to move a needle representing the velocity clockwise according to the increase of the velocity of the vehicle and to move the needle representing the velocity counterclockwise according to the decrease of the velocity. It is good to display the guide needle which shows eco-speed separately from the needle to represent. The guide needle (eco speed display needle) detects, for example, that the vehicle speed has changed from 0 (in the case where a vehicle acceleration detection means is provided, for example, when an acceleration of a predetermined value or more is detected), 5 It moves to 60 km / h at a rate of 20 km / h at a rate of 20 km / h in seconds and moves so as to overlap with a hand (real speed haul) representing the speed when the vehicle travels at a constant speed for 5 seconds. In this way, eco-driving can be performed only by increasing the vehicle speed so as to follow the movement of the guide needle. Note that the speed limit of the road currently traveled may be acquired, and the guide needle may be moved at a predetermined rate up to the acquired speed limit. For example, position information and speed limit information may be associated and stored, 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 an indicator of the eco-drive state. For example, as described above, it is preferable to display numerical values and lines (lines) of speed and acceleration in the eco-drive state in a graph or in an analog needle type meter.

The eco-drive state refers to a drive state that results in eco-drive. The eco-drive state is, for example, driving the vehicle while recording the drive state detected by the drive state detection means, recording of the drive state obtained by traveling equivalent to the eco-drive, and non-eco-drive (for example, economy It is preferable to obtain based on the difference from the recording of the drive state obtained by traveling away from the traveling speed, sudden acceleration, sudden deceleration, etc.).

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

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

Further, for example, the change of the display mode based on the drive state may be performed by enlargement / reduction. For example, when the state is not eco-drive while the graph is displayed, the portion of the graph may be enlarged. The way of enlarging the display is, for example, an aspect in which the whole screen is smoothly moved while moving the center of the screen, or a picture of a magnifying glass is displayed and a point to be enlarged of the graph in the drawing of the magnifying glass ) It is good to adopt a mode of centering and expanding. In addition, when a predetermined time has passed or when the eco-drive state is returned, the enlargement is canceled. It is good to release it smoothly. In addition, at the time of enlargement, it is preferable to notify an alarm sound and a reason for the enlargement (reason for not being eco).

Further, the change of the display mode based on the drive state may be performed by a change of the character to be displayed. For example, if you drive eco (if the degree of agreement between the detected driving status and the eco driving status is high), you may change the character so that the creature evolves, or if you do not 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-drive while having fun by changing the characters to be displayed (in addition to mere display of scores and graphs or the like). For example, in the drive state, it is preferable to monitor the speed by GPS, and to detect a sudden start, a sharp steering wheel or the like by an acceleration sensor. With the evolution of living things, for example, the ameber is displayed in the initial state, and if it is an eco-drive, it becomes a dwarf. 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-drive can be enjoyed as a game.
Thus, 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 a 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 detection means. For example, points may be increased when a drive state corresponding to eco-drive is detected, and points may be reduced when a drive state against eco-drive is detected. In this way, the driver can be motivated to drive for eco-driving with the aim of achieving high points.

  (21) Further, when the degree of coincidence between the drive state detected by the drive state detection means and the eco-drive state is equal to or more than a predetermined value, notification of the content of giving up the driver may be performed. By giving up if you like, you will be able to enjoy eco-driving while having fun.

  (22) Further, it has a function to notify when the degree of coincidence between the drive state and the eco-drive state detected by the drive state detection means has reached a predetermined state, and the notification is during the event or during the event It is preferable not to carry out in the case of at least any one within a predetermined time from. For example, when it is not in the eco-drive state (when the matching degree is equal to or less than the predetermined value), a warning may be notified, or as shown in (21), the matching degree of the driving state and the eco-drive state is predetermined. In the case of a state of being greater than or equal to the value, notification of the content of giving up the driver may be performed. Then, by not performing this notification during the occurrence of the event or within a predetermined time from the occurrence of the event, notification at the time of the occurrence of the event (for example, at the time of displaying the event occurrence screen shown in (1) or During output of a notification sound, etc.) or immediately after this notification, notification is made when the degree of coincidence between the drive state and the eco-drive state becomes a predetermined state, and the driver or the like can be prevented from feeling bothersome . For example, when a sudden acceleration or sudden deceleration is detected as a drive state, an eco-alarm is issued, but when a rapid deceleration is detected within a predetermined time after an approaching alarm to the speed measuring device or after an approaching alarm, Since it is a rapid deceleration for the approach to the speed measuring device, it is better not to give an eco-alarm.

  (23) Further, it is preferable to output a sound based on the drive state detected by the drive state detection means. In particular, the sound output may be performed in proportion to the degree of mismatch between the drive state and the eco-drive state detected by the drive state detection means. For example, in (11) to (14), when displaying the speed or acceleration of the vehicle by the inclination of the line (needle), it is preferable to output the sound at a pitch or volume according to the size of the inclination. For example, the higher the inclination, the higher the pitch and the higher the volume. In this way, it is possible to sense how much it deviates from the eco-drive state by the pitch and the size of the sound.

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

In addition, if the output of the sound is performed only when the mismatch between the drive status and the eco-drive status detected by the drive status detection means exceeds a predetermined mismatch, the sound can be output without looking at the standby screen. You can tell if you are in an eco-drive state by the presence or absence of In addition, it can be reduced that the user feels bothersome.
(24) The standby screen display means may display the eco-drive information by displaying a 3D object.

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

(26) The idle screen display unit may display the eco-drive information as a plurality of objects, and display at least a part of the objects overlapping one of the plurality of objects as a transparent color object. .
(27) It is realizable as a program for making a computer implement | achieve the function as each means in the vehicle-mounted electronic device in any one of (1)-(26).

  According to the present invention, it is possible to provide the driver with greater awareness regarding the eco-drive more naturally than before, and to provide the electronic device capable of intuitively and intuitively acquiring the driving operation to be the eco-drive. Can.

1 and 2 show the configuration of a radar detector which is a preferred embodiment of the on-vehicle electronic device of the present invention. As shown in FIG. 1, the solar panel 2 and the switch 3 are disposed on the upper surface of the case main body 1, the microwave receiver 4 is disposed inside the front side of the case main body 1, and the display 5 on the rear surface of the case main body 1. And the alarm lamp 6 and the infrared communication device 7 are arranged. Further, a GPS receiver 8 is disposed inside the upper surface side of the case main body 1. Furthermore, an adapter jack 9 is disposed on one side of the case main body 1, and a power switch 10 and a DC jack 11 are disposed on the other side. In addition, a speaker is also incorporated in the case main body 1. In the present embodiment, the dimensional shape of the display unit 5 is made larger than in the prior art (in particular, the height direction is expanded). Along with this, the height H on the rear side of the case main body 1 on which the display unit 5 is mounted is made sufficiently larger than the height H0 of the other parts. With this configuration, the display unit 5 with a larger screen can be provided as compared to the prior art.

As shown in FIG. 2, the infrared communication device 7 transmits and receives data to and from a communication device having an infrared communication device such as a cellular phone 12 built-in. 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 inside. More specifically, the data stored in the memory card 14 includes update information such as new target information (position information including longitude and latitude, type information, etc.), and the update information is transmitted via the control unit 18 Are stored (downloaded) in the database 19 built in the device, and data is updated. The database 19 can be realized by a non-volatile memory (for example, an EEPROM) externally connected to the microcomputer in the controller 18 or the microcomputer. In the database 19, information on a certain target is registered at the time of shipment, and data and the like 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 of the present embodiment includes a wireless receiver 15 and a remote control receiver 16. The wireless receiver 15 receives an incoming wireless signal of a predetermined frequency. The remote control receiver 16 performs data communication with the remote control (portable device: child device) 17 and performs various settings for the device. The switch unit 3 is also connected to the control unit 18 (not shown), and can perform the same setting as the remote controller 17.

In addition, the control unit 18 executes predetermined processing based on the information input from the above-described various input devices (GPS receiver 8, microwave receiver 4, radio receiver 15, etc.) corresponding to the drive state detection means. And outputs a predetermined alarm / message using an output device (display unit 5, alarm lamp 6, speaker 20, etc.). The basic configuration of these can be basically the same as the conventional one.

  The function of the radar detector according to the present embodiment is stored in the EEPROM of the control unit 18 as a program executed by a computer of the control unit 18, and is implemented by execution of the program by the computer of the control unit 18.

FIG. 3 is a view 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. Moreover, FIG. 4 is a figure which shows the warning screen 60 as an event generation | occurrence | production screen which the control part 18 in the radar detector of this embodiment makes the display part 5 display.

  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, velocity, altitude, and current time from the GPS receiver 8 every second, and the current position corresponds to the position of the target stored in the database 19 and the predetermined position as a predetermined event. When the distance (for example, 1 km or less) is reached, an alarm for approaching the target is output from the speaker 20 and the alarm screen 60 is displayed on the display unit 5.

Also, when the microwave receiver 4 receives the microwave emitted by the speed measurement device as a predetermined event, the alarm screen of the microwave reception alarm is displayed as a predetermined event occurrence 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 alarm screen for approaching the emergency vehicle is displayed as a predetermined event generation screen.

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

The standby screen 40 has an icon display area in the upper part, a display area for points and graphs in the middle part, and a display area for integrated points, time, and hour speed in the lower part. In the icon display area 41, an icon indicating the current setting state (for example, various modes etc.) and information on the traveling location (for example, whether it is a parking prohibition monitoring area or not) 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.

In the graph display area, the upper part is a speed graph 43, and the lower part is an area for drawing an acceleration graph 47. The velocity graph 43 is a graph showing velocity 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 an interval of one second, and expresses the acquired value by the size of a bar (vertical direction line). That is, when the power is turned on, drawing of a bar is started from the position on the right adjacent to the vertical axis 46, and the next bar is drawn at a position adjacent to the previously drawn bar. Thus, in four minutes, the bar is drawn to the right end of the graph display area. When drawing to the right end of the graph display area is performed, the first drawn bar is erased and moved to the left by one bar, and then the bar is drawn. After this, the graph is drawn while being scrolled. With regard to the size of the bar, the size of the bar is 0 at a speed of 0 km / h, the size of the bar is 60 km / h, and the drawing reaches the position of the economic speed reference line 44. The vertical axis 46 is 110 km / h at a speed of 110 km / h. Draw in the same size as the top edge. When the velocity exceeds 110 km / h, the image is drawn with the same height as 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 mounted uniquely, 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 of acceleration 0. In the present embodiment, although the velocity graph 43 and the acceleration graph 17 use the vertical axis 46 and the horizontal axis 42 in common, axes may of course be displayed separately. Also, in this case, the line 45 of acceleration 0 and the horizontal axis can be made common. The control unit 18 acquires velocity information from the GPS receiver 8, obtains acceleration from the history of the acquired velocity information, and expresses the acquired value by the size of a bar (vertical line). That is, when the determined acceleration indicates acceleration, a bar corresponding to the magnitude of the acceleration is drawn above the line 45 of acceleration 0, and when indicating deceleration, the acceleration below the line 45 of acceleration 0 Draw a bar according to the size of the. In addition, the drawing method of the bar is the same as the case of the velocity 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 traveling 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 +1 (adding point) when the state corresponding to the eco-drive continues for a predetermined time, the eco-drive When the state which does not correspond to is continued for a predetermined time, it is an area which displays the result which carried out -1 (deduction) by a numerical value. That is, the point of sudden acceleration is deducted when it is determined that the acceleration corresponding to the sudden acceleration, the point of rapid deceleration is deducted when it is determined that the sudden deceleration due to sudden braking etc., and the point of idling time is after the engine is started When the stopping time becomes more than a predetermined time (for example, 2 minutes), points are deducted every predetermined time (for example, one minute) thereafter, and the economic traveling speed point is in a predetermined range (for example, 60 / h plus) from 60 km / h. If the time not traveling in the range of minus 5 km / h continues for a predetermined time (for example, 5 minutes), the point is deducted. When the state other than the above continues for a predetermined time (for example, 2 minutes) for each point, each point is added. It is sufficient to create a non-eco-drive condition, measure it, and determine it based on the measurement result as to under what condition the point deduction and addition will occur. The idling time may be detected by detecting the time when the speed obtained from the GPS receiver 8 is zero.

In the lower-side integrated point display area 49, an average value of each point displayed in the point display area 48a for rapid acceleration, the point display area 48b for rapid deceleration, the point display area 48c for idling time, and the point display area 48d for economic traveling speed Display
Further, the current time acquired from the GPS receiver 8 is displayed in the time display area 51, and the hour-speed acquired from the GPS receiver 8 is displayed in the hour-speed display area 50.

  As described above, when a predetermined event occurs, that is, for example, the control unit 18 determines whether the current position is at a predetermined distance (for example, 1 km or less) from the position of the target stored in the database 19. When it is determined that the target object is approaching, an alarm for approaching the target 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 occurrence screen.

  The alarm screen 60 has an icon display area 61 and an alarm object name display area 62 in the upper left side, an alarm object icon display area 63 in the middle left side, and a current speed display area 64 and a speed limit display area 65 in the lower left side. The alarm screen 60 has a distance display area 66 from the alarm object in the upper right, a radar scope display area 67 for displaying the relationship between the position 67a of the alarm object and the vehicle position 67b in the middle on the right as a bird's eye view, 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 obtained from the GPS receiver 8 substantially matches the position of the target 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 of ending the approach warning to the target. That is, the control unit 18 outputs an audio as, for example, “passes the position of the velocity measurement device”. After voice output, the control unit 18 performs display processing of the standby screen 40 on the display unit 5.

In this way, when an alarm occurs, information on the alarm can be obtained, while in the standby state where no alarm occurs, the eco-drive information is displayed as a graph or point on the standby screen 40, You can be conscious of eco-driving on a daily basis.

  In particular, the user often pays attention to the alarm screen 60, so even when switching from the alarm screen 60 to the standby screen 40, the contents of the standby screen 40 naturally tend to be noted. Therefore, it becomes possible to make a deep impression on the contents of the standby screen 40, that is, the eco-drive information, by using the attention on the alarm screen 60. Therefore, it is possible to make the driver conscious about eco-driving more naturally than before. In particular, when the display of the alarm screen 60 is ended, a voice is output, so that the driver can be efficiently and effectively aware of the eco-drive.

In addition, eco-drive information is designed to change graphs and points as time passes. If the driver looks at the display unit 5 and drives while the vehicle is stopped or the like so that the points become high so that the graph is as flat and as smooth as possible, eco-driving is achieved.

In the present embodiment, the time axis is taken in the horizontal direction and the physical quantities of velocity and acceleration are taken in the vertical direction for drawing, but for example, the time axes are taken in the vertical direction and the physical quantities of velocity and acceleration are taken in the horizontal direction. It may be taken and drawn.

  In order to display the economic speed reference line 44, which serves as a guideline, at a position corresponding to the economic speed, how much the user's speed deviated from the speed and acceleration at which the eco-drive was made 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 the present embodiment, the eco-drive information related to idling is displayed as a numerical value of points in the point display area 48c of the idling time. For example, “idle time n seconds” (n is an idle time second) on the idle screen 40 A numerical value may be displayed, such as a numerical value representing a number.

  Although the GPS receiver 8 is used for speed detection in this embodiment, there is a problem that it is difficult to measure stop or low speed travel when speed is measured by GPS. Therefore, it is better to use the engine speed. As a method of detecting the number of revolutions of the engine, for example, a method of detecting the number of revolutions of the engine from alternator noise superimposed on a power supply line of a car or ignition noise may be used. For example, when power is supplied from the DC jack 11, the power is supplied from the vehicle's cigar socket through the cigar plug cord, so the engine speed from the alternator noise or ignition noise of this power supply Should be detected. Various known methods can be used as this method.

If the speed of the vehicle detected by the GPS receiver 8 is less than a predetermined speed, eco-drive information is displayed based on the engine speed, and the speed of the vehicle detected by the GPS receiver 8 is a predetermined speed In the above case, the graph or point of FIG. 3 may be displayed based on the speed of the vehicle detected by the GPS receiver 8.

In this way, even when the vehicle speed detection means is configured by the GPS receiver 8 in which it is difficult to obtain sufficient accuracy in a low speed state (state less than a predetermined speed), accurate graphs and points can be obtained. Can be provided. How to accelerate without depressing the accelerator at the time of the start of the car greatly affects the eco. 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. Further, for example, the ratio between the speed and the number of revolutions of the engine may be displayed on the standby screen 40 as eco-drive information.

In addition, for example, various information flowing on the in-vehicle LAN existing in the vehicle may be detected. Further, for example, a temperature sensor for detecting 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 where people feel comfortable without using the air conditioner) In this case, a display may be displayed on the standby screen 40 as eco-drive information indicating that eco-drive can be performed when the air conditioner is stopped. At this time, whether the display is to be performed may be determined in consideration of the operating state of the air conditioner, the temperature in the vehicle, and the like. Further, means for detecting the engine rotational speed, the vehicle vibration state, and the gear shift state may be used.

A vibration sensor is connected to the control unit 18 to detect the vibration of the vehicle instead of or together with the engine rotational speed, and the standby screen 40 has the graph shown in FIG. 3 based on the engine rotational speed detected by the vibration sensor. Or you may make it display a point. A known method can be used as a method of detecting the engine speed from the vibration.

Alternatively, a gear shift state detector for detecting a gear shift state may be connected to the control unit 18, and the standby screen 40 may display the graph or point of FIG. 3 based on the gear shift state detected by the gear shift state detector. . For example, if it is determined that the gear shift state is a state of speed 0 with the neutral or parking state and vibration is detected by the vibration sensor, it is determined that the idling state is continued, and if this state continues for 1 minute or more It is good to subtract and display. As the gear shift detector, for example, a sensor that detects a shift position, or information flowing in the in-vehicle LAN can be used. Also, the gear shift state may be detected from the speed data from the GPS receiver 8 and the number of revolutions of the engine. Further, the number of rotations of the engine may be displayed on the standby screen 40 as eco-drive information.

Further, on the standby screen 40, the acceleration of the vehicle may be displayed as a slope of a straight line as eco-drive information. That is, for example, it is preferable to display the latest acceleration thus obtained as a slope in the drawing area of the velocity graph 43 of the graph display area as a tangent line tangent to a point on the right end (that is, the latest velocity) of the velocity graph 43. In this way, for example, if the level is horizontal, the current acceleration is zero, if it is rising to the right, acceleration is currently occurring, and if it is falling to the right, deceleration is currently occurring. This makes it possible to instantly know the state of acceleration. Further, it is easier to understand if the color and thickness of a straight line are changed within acceleration and deceleration or within a predetermined acceleration range.

As described above, eco-drive information can be displayed as a graph or numerically displayed, but the speed and acceleration can be analog needle type with eco-drive information or as eco-drive information. It may be displayed in the form of a meter. The analog needle type meter can sense the movement of the touch sensuously, and can learn eco driving (eco driving) without looking at the meter. For example, it is good to display as an eco meter of the sports meter style shown in FIG.

5 and 6 show another embodiment of the idle screen 40. As shown in FIG. The standby screen 40 displays the analog needle type acceleration meter 80 on the left side. In the analog needle type acceleration meter 80, as the eco-drive information, the acceleration of the vehicle calculated from the amount of change in the history of the speed acquired from the GPS receiver 8 is displayed and The rapid acceleration guidelines 84 are displayed. When the acceleration is 0, it is displayed as an acceleration needle 82 in the vertical direction as shown in FIG. 5, and when accelerating, the acceleration needle 82 is inclined to the right as shown in FIG. Display to tilt 82. The rapid deceleration guideline 83 is displayed at the boundary between the normal deceleration condition and the rapid deceleration condition which is not an eco-drive, and the rapid acceleration guideline 84 is the boundary location between the normal acceleration condition and the rapid acceleration not being an eco-drive It is displayed on. You can determine the appropriate position by checking the position where the rapid deceleration guideline 83 and the rapid acceleration guideline 84 are to be displayed by performing the rapid deceleration and acceleration in the actual vehicle equipped with this radar detector. .

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

When it is detected that the speed acquired from the GPS receiver 8 has changed from the state of 0, the eco-speed guide hand 92 moves up to 60 km / h at a rate of 20 km / h in 5 seconds. At this time, it is preferable to draw the eco-speed guide needle 92 so that the indicated speed smoothly (progressively) increases. The eco-speed guide needle 92 is particularly an index of eco-drive at the time of start. That is, if the speed needle 93 is increasing faster than the increase in the eco-speed guide needle 92 (the acceleration of the actual vehicle speed is large), it is estimated that the vehicle is not in the eco-drive state due to a sudden start. it can. Therefore, the driver can understand that it is preferable to drive (press the accelerator) such that the current speed of the vehicle (the speed indicated by the speed needle 93) is lower than or equal to that of the eco-speed guide needle 92.

In addition, as one of the eco-drives, the vehicle may travel at a constant speed without changing the speed. Therefore, for example, when it can be considered that the vehicle travels at a constant speed for 5 seconds by the speed acquired from the GPS receiver 8, it is also in the eco-drive state, so the eco-speed guide needle 92 is moved to overlap the speed needle 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 and accelerates to approach 60 km / h. Acceleration and deceleration may be repeated as if you are decelerating without maintaining 60km / h from traffic conditions etc., but if you are traveling at a constant speed, it will be stable at the speed according to 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 speed (the speed indicated by the speed needle 93) and the eco-speed guide needle 92 are overlapped and drawn By doing this, constant speed driving can be promoted.

In addition, even if the speed of constant speed driving exceeds 60 km / h, there is also a possibility that, for example, you are traveling on a freeway, so if you are traveling at constant speed, speed needle 93 and eco speed guide needle 92 And draw.

Note that the maximum speed indicated by the eco-speed guide needle 92 may be set, and when traveling at or above the maximum speed, the eco-speed guide needle 92 may be drawn 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 an expressway, the eco-speed guide needle 92 By pointing it, it is possible to encourage constant speed driving at economic speeds. The type of road in which the vehicle is traveling may be determined, and the maximum speed indicated by the eco-speed guide needle 92 may be different according to the type of road.

In FIG. 5, since the speed acquired from the GPS receiver 8 is 0 km / h, the speed needle 93 points at 0 km / h, and the eco-speed guide needle 92 also indicates 0 km / h. Therefore, both are displayed overlapping each other. FIG. 6 shows that the speed hand 93 points to 34 km / h because the speed obtained from the GPS receiver 8 is 34 km / h, and the speed obtained from the GPS receiver 8 has changed from the state of 0 5 seconds after the detection of, and points at 20 km / h per hour. In the state of FIG. 6, since the eco-speed guide needle 92 is in the counterclockwise direction (left direction) of the speed needle 93, it can be seen at a glance that the speed is too high (a 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 rapid acceleration guideline 84, and it can be seen at a glance that it is in a rapid acceleration state.

Thus, from the difference between the positions of the eco-speed guide needle 92 and the speed needle 93, it can be recognized at a glance whether it is eco-drive or not. Further, eco-drive can be performed only 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. When driving on an expressway, eco-drive can be easily performed by driving so that the speed needle 93 comes between the high speed traveling economic speed minimum value guideline 94a and the high speed traveling economic speed maximum value guideline 94b.

Although the eco-speed guide hand 92 is moved to 60 km / h per hour, for example, the current position acquired from the GPS receiver 8 and the database 19 are stored by associating the position and the speed limit in the database 19. The speed limit needle of the eco-speed guide may be moved to the acquired speed limit by acquiring the speed limit of the portion currently traveled from the position stored in.

In addition, 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, it is preferable to change the display mode by changing the color. For example, it is preferable to change the display color of the hour speed acquired from the GPS receiver 8 displayed in the hour speed display area 50 depending on whether it is eco-drive or not. 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 in the case of other speeds, it may be red. Similarly, the color of the bars of the velocity graph 43 and the acceleration graph 47 may be changed depending on whether or not the vehicle is eco-drive.

Also, for example, when the state is not eco-drive while the graph is displayed, the portion of the graph may be enlarged and displayed. The way to magnify the image is, for example, to make the whole screen move smoothly around the part while enlarging it, or to display the picture of the magnifying glass and to enlarge the graph in the picture of the magnifying glass (Eco It is good to put it in the center and expand it. In addition, when a predetermined time has passed or when the eco-drive state is returned, the enlargement is canceled. It is good to release it smoothly. In addition, at the time of enlargement, it is preferable to notify an alarm sound and a reason for the enlargement (reason for not being eco).

In addition, for example, when the character is displayed on the standby screen 40 and eco-driving is performed (in the case where the detected speed is in the range of economic traveling speed (for example, 60 km / h) and plus or minus 10 km / h), organisms evolve Display the character to change as you go, and if the eco-drive is not performed (if the detected speed is not within the range of the economic running speed (for example 60km / h) and plus or minus 10km / h), the creature will be degraded May be displayed to change the character. That is, it is possible to learn eco-drive while having fun by changing the characters to be displayed (in addition to mere display of scores and graphs or the like). With the evolution of living things, for example, the ameber is displayed in the initial state, and if it is an eco-drive, it becomes a dwarf. 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-drive can be enjoyed as a game.

In addition, when the integrated points reach a value exceeding 90 points, it is preferable to give a notification of the contents of giving up the driver. By giving up if you like, you will be able to try eco-driving while having fun.

Further, for example, the acceleration is obtained based on the history of the speed acquired from the GPS receiver 8, and when the acceleration corresponding to the rapid acceleration or the rapid deceleration is obtained, the eco-alarm You may make it alert | report. For example, an eco-alert is notified by voice like "It is a sudden acceleration" or "a 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 end of the display of the alarm screen 60. In this way, when the rapid deceleration is detected within the predetermined time after the approaching alarm to the speed measuring device or within the predetermined time after the approaching alarm, since the rapid deceleration for approaching the speed measuring device, the eco alarm is It disappears and the user does not feel bothersome.

When an acceleration corresponding to rapid acceleration or rapid deceleration is obtained, that is, as shown in FIG. 6, when the acceleration needle 82 is further to the right beyond the rapid acceleration guideline 84, the magnitude of the inclination is Outputs the sound with the corresponding pitch and volume. For example, the higher the inclination, the higher the pitch and the higher the volume. In this way, it is possible to sense how much it deviates from the eco-drive state by the pitch and the size of the sound. 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 obtained, the velocity of the acceleration needle 82 can be You can imagine the position, you can get more intuitive eco-drive. When the acceleration of the vehicle is displayed as a straight slope as the eco-drive information, it is preferable to output the sound with a pitch or volume according to the size of the slope.

In addition, when power is supplied from the DC jack 11, power is supplied from the vehicle's cigar socket through the cigar plug cord, so the alternator noise of this power is amplified and output as sound. You may do so. In this way, the relationship between the state of the engine and the eco-drive can be known from the size and pitch of the noise noise, etc., and the driving operation that becomes the eco-drive or the driving operation that does not become the eco-drive can be sensuous・ Can be intuitively understood.

  According to the radar detector of each embodiment as described above, awareness of the driver regarding the eco-drive can be made more naturally than before, and the driving operation to become the eco-drive is intuitively acquired intuitively be able to.

In addition, as a display mode of eco-drive information, not only these but various aspects can be taken. For example, as shown in FIG. 7, on the graph (velocity graph 43, acceleration graph 47) or numerical values (the numerical values displayed in the point display area 48, the integrated point display area 49, and the hour-speed display area 50) shown in FIG. A display mode may be adopted in which the acceleration needle 82 shown in FIG. 5 is superimposed and displayed. In this way, the current state of acceleration can be known by the movement of the acceleration needle 82, and the state of the speed and acceleration so far can be known from the speed graph 43 and the acceleration graph 47, and the point display area 48 Also, various points displayed in the integrated point display area 49 can be known simultaneously. Further, as can be seen by comparing FIG. 3 and FIG. 7, the display mode (arrangement, size, etc.) of each graph or numerical value can be freely set (note that the reference numerals of FIG. 3 and FIG. The symbols of denote the corresponding symbols).

Furthermore, as another display mode of eco-drive information, as shown in FIG. 8, display of a 3D object may be performed. In the idle screen 40 of FIG. 8, an acceleration needle 82 which is an analog needle type meter, a scale 102 provided at a position indicated by the acceleration needle 82 drawn as a 3D object, and a reduction provided at the left side of the analog needle type meter Deceleration digital meter 104b, which is a digital meter that digitally displays the speed, and 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 provided under these meter sections A velocity graph 43, a velocity display area 50, an integrated point display area 49, a point display area 48 and the like are drawn. The acceleration needle 82, which is an analog needle type meter, draws so as to point directly below as shown in FIG. 8A when the acceleration is 0, and when the acceleration is positive (during acceleration), FIG. Draw so that it moves smoothly (analogically) according to the magnitude of acceleration to the right as shown in). Similarly, when the acceleration is negative (during deceleration), drawing is performed so as to move smoothly (analogically) to the left according to the degree of deceleration.

As shown in FIG. 8A, among the objects overlapping with each other, 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 region of the velocity graph 43 is drawn in a semitransparent color, and the velocity 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 content can be secured, and a plurality of eco-drive information It is possible to get easily at the same time.

Further, as shown in FIG. 8A, the scale 102 arranges spherical 3D objects on the circumference at predetermined intervals, and the color of each spherical 3D object is different for each zone. That is, in the case of acceleration 0, a predetermined number of regions (example in FIG. 8) from the location where the acceleration needle 82 points (called the origin; the location where the acceleration needle 82 in FIG. In this case, the left and right five from the origin are made blue, the predetermined number of regions (five in the example of FIG. 8) are made yellow before that, and the region after that is made red.

  The acceleration needle 82 points to the range of the blue scale 102 if the acceleration is a value that falls within the safety range, and points to the range of the yellow scale 102 if the acceleration falls to a caution area, and the acceleration is dangerous. If it is a value corresponding to the area, it is displayed to indicate the range of the red scale 102. In addition, it is good to adjust by performing acceleration / deceleration in the state mounted in the actual vehicle which area the acceleration falls in.

Further, the same color as the color of the scale of the zone pointed to by the acceleration needle 82 is mixed with the background color and displayed as the background color of the standby screen 40 as a gradation. 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 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 displayed as a yellow gradation. Similarly, when the acceleration needle 82 points to the zone of the red scale 102, the background color is displayed as a red gradation.

Furthermore, the color of the scale 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 104 a and the deceleration digital meter 104 b 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, and each of the lower five rectangles is blue, the upper five rectangles are yellow, and the upper 15 Each rectangle is a red display area. Then, as shown in FIG. 8A, when the acceleration is 0, each rectangle is not filled with these colors and displayed in gray. On the other hand, as shown in FIG. 8B, when the acceleration needle 82 points to the 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. 8 (b), when the acceleration needle 82 points to the third scale 102 from the bottom of yellow, the five blue areas from the bottom and the three yellow areas above that from the rectangular area are Fill in. In this way, the digital meter is displayed together with the analog needle meter, and the color of the scale of the zone indicated by the analog needle meter is associated with the color of the digital meter, and the state of acceleration is safe. It is easy and intuitive to know whether or not.

The filling of the rectangular areas of the acceleration needle 82 and the acceleration digital meter 104a and the deceleration digital meter 104b may be completely interlocked, but the absolute value of the acceleration is lower than that after the filling. In this case, after a predetermined time (for example, one second) elapses after the image is lowered, the drawing may be performed so as to return to the gray display sequentially from the rectangular area located above. In this way, when the acceleration changes, it is possible to easily know the state of the peak value from the acceleration digital meter 104a and the deceleration digital meter 104b. That is, the movement of the acceleration needle 82 indicates the change in acceleration, and the display of the acceleration digital meter 104a and the deceleration digital meter 104b indicates the maximum acceleration within a predetermined time.
Also, each 3D object may be moved or a virtual camera for capturing a 3D object may be moved according to the state of acceleration.

At the start of displaying eco-drive information, it is preferable to perform animation display so that the 3D object enters the screen from outside the screen. For example, it is good to move and draw the camera position which image | photographs 3D object and 3D object in order shown to FIGS. 9-12. That is, while a part of the scale 102 is enlarged and gradually reduced, the general point display area 49, the hour-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 sliding the point display area 48 from the right side. By doing this, it can be easily understood that the standby screen 40 has been switched to the display of eco-drive information.
