  By the way, as the information display for supporting the driving skill improvement described above, instantaneous information based on the driving operation at the present time, that is, instantaneous information display for displaying the quality of the driving operation immediately before including the current time may be performed. This is effective for allowing the driver to judge whether the driving operation performed this time is good or bad. On the other hand, it is effective to determine whether the driving operation is good or bad throughout the current driving by performing the comprehensive information display that displays the quality of the overall driving operation for the continuous driving operation for a long time. .

  On the other hand, displaying the instantaneous information display and the comprehensive information display related to the driving operation described above together, for example, in the meter panel takes a considerable display space, and the display information becomes too much. Therefore, there is room for improvement in terms of concentrating on driving.

The present invention has been made in consideration of the above circumstances, and its purpose is to concentrate on driving by performing both instantaneous information display and general information display regarding the quality of driving operation , and display of a comprehensive information display. An object of the present invention is to provide a vehicle display device that can analyze and look back on its own driving based on the contents.

In order to achieve the above object, the following solution is adopted in the present invention. That is, as described in claim 1,
A first display area for displaying score information indicating the quality of the driving operation of the driver for a short period up to the present time ;
A second display area for displaying accumulated information obtained by accumulating score information for the short period over a long period of time;
With
The first display area is located within the driving field of view,
The second display area is spaced from the driving field of view and is positioned within a visible range of the driver ,
In the second display area, comprehensive accumulated information indicating the quality of driving operation accumulated from when the ignition switch is turned on until it is turned off and accumulated information about individual operation items are displayed together. ,
The accumulated information related to the individual operation items is score information indicating the quality of each operation of the brake, accelerator, and steering wheel,
The comprehensive accumulated information is score information indicating whether the driving operation is good or bad based on the front / rear / left / right acceleration generated based on the driving operation of the driver,
It is like that.

According to the above-described solution technique , the score information display within a short period regarding the quality of the current driving operation can be easily and clearly observed by observing the first display area within the driving field of view while concentrating on driving. I can know. In addition, when there is no need to concentrate on driving or when the driving is stopped, such as when the vehicle is stopped or after driving is stopped, the comprehensive information display regarding the quality of driving operation is clearly confirmed by observing the second display area. be able to. Further, for example, a passenger who does not need to concentrate on driving, such as a passenger on the passenger seat, can always see the second display area, so the driver can check the contents of the comprehensive information display via the passenger. . Thus, by checking the information displayed in each display area, it becomes possible to improve the driving skill while having fun.
Furthermore, it is possible to learn how to perform a comprehensive driving operation based on accurate information accumulated over a long period of time from when the ignition switch is turned on to when it is turned off. It is possible to learn how to operate for each operation and handle operation.

A preferred mode based on the above solution is as described in claim 2 and the following. That is,
The first display area is provided in a meter located in front of the driver and in the upper half of the meter (corresponding to claim 2). In this case, the driver can easily and clearly confirm the information displayed in the first display area while keeping his / her eyes on the front or slightly lowering his / her line of sight.

  In the first display area, information on the level of driving based on the front / rear / right / left acceleration generated based on the driving operation is displayed as color information as the instantaneous information. Item 3). In this case, the good / bad level of the driving operation can be immediately confirmed with the color while accurately displaying the good / bad level of the driving operation based on the front / rear / left / right accelerations generated based on the driving operation.

According to the present invention, it is possible to concentrate on driving by performing both the short-term score information display and the long-term comprehensive information display regarding the quality of driving operation , and the self-driving based on the display contents of the comprehensive information display You can analyze and look back on.

  FIG. 1 shows the vicinity of a driver's seat of an automobile as a vehicle. In FIG. 1, 1 is an instrument panel, 2 is a front window glass, and 3 is a steering handle. In FIG. 1, a left-hand drive vehicle is shown.

  A front end portion of the center console 4 extending in the vehicle body front-rear direction is connected to a center portion in the vehicle width direction of the instrument panel 1. On the center console 4, an operation knob 5 for operating the transmission, a switch panel unit 6, and an armrest 7 are sequentially arranged from the front side to the rear side. A parking brake lever 8 is provided on the steering wheel 3 side of the center console 4. In the switch panel unit 6, a dial switch 10 and a volume control switch 20 are disposed in the vicinity thereof.

  A meter panel 30 is disposed on the instrument panel 1 immediately before the steering handle 3. In the instrument panel 1, a display screen 40 made of a thin panel such as a liquid crystal screen is disposed at a substantially central portion in the vehicle width direction. Further, a display screen 41 composed of a head-up display is arranged in the instrument panel 1 immediately before the meter panel 30.

  Details of the meter panel 30 portion are shown in FIG. In FIG. 2, an analog display type engine tachometer (tachometer) 31 is arranged in a circular arc shape at the center of the meter panel 30, its pointer is indicated by reference numeral 31a, and its circular scale is indicated by reference numeral 31b. Indicated. A digital display type speedometer 32 is arranged in a circular frame shape constituting the engine tachometer 31.

  A small display (for example, a thin display such as a liquid crystal screen) 33 is disposed on the inner upper portion of the scale 31 b of the engine tachometer 31. As will be described later, the display 33 forms a first display area, and the display 40 described above forms a second display area. In the embodiment, the display 33 has an arc shape and is disposed so as to be positioned above the upper half of the meter panel 30. The display 33, including its area setting and shape setting, is visible to the driver who is gazing forward for driving, and can be clearly recognized at least by slightly lowering his line of sight. Yes. In particular, as will be described later, the display 33 has a display form that can instantaneously determine whether the driving operation is good or bad by “color (color coding)”.

  In the meter panel 30, a gear stage display unit 34 that displays the current gear stage of the transmission is arranged on the upper part of the left side of the engine tachometer 31 and the speedometer 32, and an odometer display unit 35 is arranged on the lower part thereof. Is arranged. Further, in the meter panel 30, a temperature display unit 36 is disposed at the upper part of the right side of the engine tachometer 31 and the speedometer 32, and a fuel consumption display unit 37 indicating the current fuel consumption is disposed at the lower part thereof. A fuel gauge 38 is disposed in the lower part.

  FIG. 3 shows a controller (control unit) configured using a microcomputer for performing display control of the displays 40 and 33. Signals from various sensors S1 to S6 are input to the controller U. S1 is a brake sensor that detects a brake operation amount. S2 is an accelerator sensor that detects the accelerator opening. S3 is a steering angle sensor that detects the steering angle of the steering wheel. S4 is a longitudinal acceleration sensor that detects longitudinal acceleration acting on the vehicle body. S5 is a lateral acceleration sensor that detects lateral acceleration acting on the vehicle body. S6 is a vehicle speed sensor that detects the vehicle speed.

  Based on signals from various sensors S1 to S6 (including processing signals obtained by differentiating input signals, for example), the controller U displays on the displays 40 and 30 the determination results regarding the good and bad driving operations as will be described later. Take control.

  Next, the contents of control by the controller U will be described with reference to FIG. First, the quality of driving based on the driving operation of the driver (driving level) is classified into three levels of “friendly driving”, “simple driving”, and “swaying driving” in the embodiment. is there. In terms of image, gentle driving does not move the occupant's body, and all operations of the brake, accelerator, and steering wheel are slow, and although it is preferable for fuel-saving driving, it is called slow or slow driving Thus, the driving is such that other vehicles in the vicinity feel annoying. This easy operation is indicated by “green (G)” when identified by “color”.

  On the other hand, the driving that shakes the body is like an image that repeats the rough and rough operation of blowing and loosening the accelerator, and the passenger's accelerator operation is rough and the passenger leaves or sticks. Even when turning at an intersection, the body is held by the support part on the seat side, but the image is a mixture of strength and weakness. In any case, the operation of any one of the brake, the accelerator, and the steering wheel is too rapid, and the longitudinal, left, and right accelerations generated in the vehicle body are greatly or suddenly changed, resulting in so-called rough driving (or dangerous driving). When the operation that the body shakes is identified by “color”, the display is “white (W)”.

  The supple driving is an intermediate driving between the gentle driving and the driving that shakes the body. By judging the traffic situation accurately and grasping the performance of the car on board, it accelerates to what speed. , It can be properly judged in the situation of the situation if it decelerates, or even at cornering to minimize energy loss (not too fast, not too slow) It becomes the driving of the image that turns smoothly with the speed and handle operation . When this supple operation is identified by "color", it is displayed as "blue (B: blue)".

  FIG. 8 schematically illustrates a gentle operation, a supple operation, and a swaying operation with respect to a brake operation and an accelerator operation that generate acceleration in the front-rear direction, such as during acceleration and deceleration. In addition, FIG. 9 shows an image of a gentle operation, a supple operation, and a swaying operation with respect to the steering wheel operation when the vehicle starts to turn and generates straight acceleration. FIG. 10 shows the situation of FIGS. 8 and 9 together.

  FIG. 11 schematically illustrates an easy operation, a supple operation, and a swaying operation with respect to an accelerator operation and a steering wheel operation that generate accelerations in the forward / backward and left / right directions during acceleration and turning. FIG. 12 collectively shows the situation of FIG. 11 including the brake operation.

  FIG. 13 shows an example of a case where easy driving and flexible driving are separated from driving where the body shakes, using the change width of acceleration generated in the vehicle body and the speed of change of acceleration as parameters. Further, FIG. 14 shows a case where gentle driving and flexible driving are separated from each other by using acceleration (magnitude) and body shaking at a moved position (for example, as a change in acceleration) as parameters. An example of doing this is shown.

  Here, the display 33 serving as the first display area arranged on the meter panel 30 described above corresponds to the gentle driving and the flexible driving determined according to the driving operation immediately before including the current time and the driving where the body shakes. Color display is performed. That is, when it is determined that the driving is easy, the display 33 is lit in “green”. In addition, when it is determined that the body is shaken, the display 33 is lit in “white”. Further, when it is determined that the driving is supple, the display 33 is lit in “blue”.

  The determination result of the gentle driving and the flexible driving according to the color displayed on the display 33 and the driving that shakes the body is a determination based on the driving operation in a short period of time, for example, 10 seconds before the current time, This is a determination result for an instantaneous driving operation. Moreover, the determination result of the driving operation corresponding to the color display on the display 33 is, for example, a result obtained by integrating the determination results obtained by the determination methods as illustrated in FIGS. 10 and 12 to 14. For example, each determination result can be weighted for final determination, or a determination result with a large number of determination results within a certain time can be used as final determination. The characteristics as shown in FIGS. 10 and 12 to 14, the determination logic for obtaining the determination result, and the like are stored in advance in storage means (memory) equipped in the controller U.

  On the display 40 serving as the second display area, stored information (including information obtained by processing the stored information) is displayed that stores the result of determining whether the driving operation is good or bad over a long time (period). . The display on the display 40 can be switched between two types of display modes, a simple mode and a drive mode. FIG. 4 shows an example of a display mode in the simple mode. As the display content, the stage display unit 51 indicating how many times the driver has reached the stage is set. In the embodiment, “3rd STAGE” is displayed and the third stage is reached. It is shown.

  In the display 40, for example, a score display indicating whether the driving operation is good or bad with respect to the driving operation every minute is displayed in a bar graph type for 10 pieces (that is, for the past 10 minutes), and the bar graph type score display section is displayed. This is indicated by reference numeral 52. The score display is a five-level display, where “0” means the worst driving operation, “5” means the best driving operation, and “3” indicates an intermediate driving operation state (in FIG. 4 and the like). The scale from 0 to 5 indicating the score is not shown). In general, when the score is between 2.5 and 3.5, it is regarded as an average driving operation, and when the score exceeds 3.5, it is above average, and when the score is below 2.5, it is below average. It is said.

  The score display section for the current 10 minutes is indicated by reference numeral 53, and the current score is displayed as 3.9 in FIG. Also, immediately below the current score display section 53, the average score from when the ignition switch is turned on until the present is displayed on the average display section 54, and in FIG. 4, average 4.0 is displayed. The evaluation of the current score and the average score (display of evaluation) is continuously performed while being updated as appropriate from when the ignition switch is turned on to when it is turned off. When the ignition switch is turned off and then on again, the current score is stored and updated as the previous score.

  In order to identify the driver to be evaluated, the driver display unit 55 is displayed (“Driver: XXX” is displayed. Note that the driver is registered in advance. In addition, the current time is displayed on the time display unit 56 displayed directly above the driver display unit 55. Further, the drive mode is displayed below the bar graph type score display unit 52. A touch-type mode change switch unit 57 for changing is displayed.

  While driving, the driver concentrates on driving and looks at the display 33 in the meter panel 30 to determine whether the driver is currently driving gently or swinging by color coding, or You can immediately see if you are driving supple. By confirming the display result of the display 33, it is possible to immediately determine whether or not the driving operation performed immediately before is appropriate, and it is possible to improve the next driving operation.

  When it is not necessary to concentrate on driving or when it is in a low situation, such as when the vehicle is stopped, by observing the display 40, it is determined whether or not the driving operation over a long period of time is appropriate. Can do. By having passengers such as passengers in the passenger's seat inform the display contents on the display 40, the driver can check the display contents on the display 40 even during traveling.

  FIG. 5 shows a display example of an ending screen that is displayed when the ignition switch is turned OFF in the simple mode. On this ending screen, the bar graph type stretching score display is not performed, while the display on the driving advice display unit 60 displays advice for better driving operation. In FIG. 5, the display content is “Excellent driving. Let's maintain this condition and aim for the higher level”. On the other hand, for example, there may be a display in which a driving operation such as “The steering wheel operation is too rapid” or “Let the accelerator operation be performed a little more slowly” is performed.

  FIG. 6 shows the display contents of the display 40 in the drive mode (display corresponding to FIG. 4). In this drive mode, the bar graph type score display section 52 is changed to a short bar graph display in which the lower portion is omitted. Instead, the brake operation display section 76, the accelerator operation display section 77, and the handle operation display section 78 are individually displayed. It is displayed with an annular shape. Each display unit 76 to 78 is displayed in different colors. In other words, a green display corresponding to gentle driving, a white display corresponding to swinging driving, and a blue display corresponding to supple driving are shown (shown with hatching in the color display part) ) In addition, it can replace with a color-coded display and can also be set as the score display which shows the quality of the operation separately on each display part 76-78. A touch panel type mode change switch unit 75 is also displayed, and the switch to the simple mode shown in FIG.

  A display example of the ending screen in the drive mode is shown in FIG. In this ending screen, as compared with the case of the simple mode, the evaluation results for each operation on the brake, accelerator, and handle are the same as in the case of FIG. 5, the brake operation display unit 76, the accelerator operation display unit 77, the handle operation. The display unit 78 is displayed, and the evaluation result corresponding to the operation is displayed in different colors (or score display) for green, white, and blue, as in the case of FIG.

  Although the embodiments have been described above, the present invention is not limited to the embodiments, and appropriate modifications can be made within the scope of the claims. The method for evaluating the driving operation is not particularly limited, and can be selected and changed as appropriate, for example, by the method described in Patent Document 1. The color used for the color classification can be changed as appropriate, and the evaluation result of the color classification can be divided into two stages or four or more stages. As the first display area, the display 41 may be used, or a head-up display may be used. The display 40 serving as the second display area can be appropriately selected as long as it is within a range that can be viewed by the driver, for example, on the surface extending in the vertical direction of the center console 4. It is also possible not to display the ending screen. Of course, the object of the present invention is not limited to what is explicitly stated, but also implicitly includes providing what is substantially preferred or expressed as an advantage.
