  However, in the display device of the above document, since the long and short hands are arranged coaxially and movable, the long hand and the short hand may move back and forth, particularly when the long hand and the short hand overlap. The short hand is hidden behind the long hand, and the visibility of the transmission ratio indicated by the short hand is significantly deteriorated.

  Further, in the display device of the above document, when the engine speed indicated by the long hand is constant, the fuel efficiency driving (eco-driving) is performed as the gear ratio indicated by the short hand decreases, and the degree of fuel efficiency is determined by the driver. Although it is possible to make a determination, if the long hand and the short hand move back and forth or overlap as described above, the determination cannot be easily performed.

The display control system may be an in-vehicle device, for example, and the in-vehicle device may be a display device mounted on a car. The display control system includes a case where the display control system includes a server or the like outside the vehicle. Further, the plurality of values that change as the vehicle travels may be values based on values acquired by sensors or the like, for example.

  The value based on the value acquired by the sensor or the like may be, for example, the sensor value itself or a value obtained by processing the sensor value by performing a predetermined process. The value processed by performing this predetermined process may be a value obtained from a value of one sensor or the like, or may be a value obtained from values of a plurality of sensors or the like. The plurality of values that change as the vehicle travels may be values acquired in the vehicle.

  Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the drawings. Note that the present invention is not limited thereby.

FIG. 1 is a schematic diagram illustrating an in-vehicle installation state of a vehicle-mounted display device according to Embodiment 1 of the display control system of the present invention.
As shown in FIG. 1, a center console 11 is incorporated in a dashboard 10 in the vehicle, and a connector 12 connected to the vehicle ECU is installed on the left side of the center console 11. In addition, on the upper side of the center console 11, a display device 20 for mounting on a vehicle, which is a feature of the present embodiment, is installed. An OBDII (OBD II) adapter 13 is detachably connected to the connector 12, and an output side of the OBDII adapter 13 is connected to the display device 20 via the cable 14.

  In addition, the display device 20 allows the driver to visually recognize a plurality of values that change as the vehicle travels, as a position corresponding to the magnitude of each value, so that the driver can visually recognize the change in each value. It is one aspect | mode of the display control system which performs control for making it display on the display part which can be visually recognized from. Further, in the present embodiment, as a plurality of values that change as the vehicle travels, a value related to the transmission ratio of the continuously variable transmission and a value related to the control amount of the configuration for giving rotation to the continuously variable transmission are provided. Shall. The value relating to the control amount of the configuration for applying rotation to the continuously variable transmission is, for example, the engine speed.

FIG. 2 is a block diagram illustrating an electrical configuration of the vehicle-mounted display device according to the first embodiment.
The display device 20 shown in FIG. 1 includes a control unit 21 that performs display control according to the present embodiment, a display drive circuit 31, and a display unit 32 such as an LCD having a dot matrix configuration.
The control unit 21 includes an input / output interface 21a, a CPU 21b, a ROM 21c, a RAM 21d, a graphic chip 21e, and a graphic memory 21f including a nonvolatile memory, and these modules are connected via a system bus.
The input interface 21a is a circuit that acquires, for example, the current value of the engine speed and the vehicle speed from the vehicle ECU via the OBDII adapter 13 as a plurality of values that change as the vehicle travels, and outputs the acquired value to the system bus 21g. Although not shown, various sensors such as an engine speed sensor and a vehicle speed sensor are connected to the vehicle ECU, and the input interface 21a of the control unit 21 detects the engine speed detected by the engine speed sensor and the vehicle speed sensor. And the current value of the vehicle speed is acquired via the OBDII adapter 13.

The CPU 21b executes a control program stored in the ROM 21c and controls the entire operation of the display device 20 of the present embodiment. At that time, the RAM 21d is used as a work area.
In response to a display command from the CPU 21b, the graphic chip 21e sequentially generates display image signals, temporarily draws them in the graphic memory 21f, and sends them to the display drive circuit 31 at every predetermined display timing. The display drive circuit 31 displays an image on the display unit 32 based on the display image signal from the graphic chip 21e. Specifically, the graphic chip 21e outputs a display image signal converted into an RGB color signal or the like to the X driver and the Y driver in the display drive circuit 31. Then, the display image signal is sent to each pixel of the display unit 32 in synchronization with the respective synchronization signals by the X driver and the Y driver, and the pixel at the intersection of the X driver and the Y driver enters the display state. Further, by scanning the X driver and the Y driver for a certain time, one display image is displayed on the screen of the display unit 32 having a dot matrix configuration.

Next, an aspect of the display image displayed on the display unit 32 of the display device 20 will be described with reference to FIG. FIG. 3 is a screen display diagram illustrating an example of a bar graph display mode according to the first embodiment.
The display image of the bar graph mode illustrated in FIG. 3 corresponds to a display as a position corresponding to the magnitude of the engine speed (referred to as “engine speed bar display”), from a substantially rectangular display area. A plurality of instruction units 41 (15 in the example of FIG. 3) having the same width (size in the horizontal direction of the screen) are arranged at regular intervals on the horizontal straight line. Similarly, in correspondence with the display as a position corresponding to the size of the gear ratio (referred to as “gear ratio bar display”), a plurality of instruction units 42 having the same width as each instruction unit 41 (in the example of FIG. 3). 15) are arranged on the horizontal straight line at the same fixed interval as that between the respective instruction units 41. The engine speed bar display and the gear ratio bar display are arranged on a horizontal straight line facing each other with a predetermined interval. This empty interval is set wider than the interval between the instruction units 41 and 42 in each bar display (in the example of FIG. 3, about eight of the instruction units 41 or 42). It is set wider than the height of the instruction units 41 and 42 (size in the vertical direction of the screen). As a result, the engine speed bar display and the gear ratio bar display are arranged on a horizontal straight line without overlapping.

  In addition, a character string display indicating the names of the engine speed bar display and the gear ratio bar display is arranged on the upper left side of each of them as “engine speed” and “speed ratio”. A character string display of “[rpm]” indicating the unit is also arranged on the right side of the character string. Furthermore, as a character string display indicating the scale of the engine speed bar display, “0” is arranged at a position corresponding to the upper left portion of the instruction section 41, and “7000” is arranged at a position corresponding to the upper right portion. Has been placed. In addition, as a character string display indicating the scale of the gear ratio bar display, “L” indicating the lowest value is arranged at the position corresponding to the upper right portion of the instruction unit 42, and at the position corresponding to the upper left portion. “H” indicating the highest value is arranged.

  The engine speed bar display is an instruction display to a position at a distance from the reference position (0 [rpm]), and the gear ratio bar display is an instruction display to a position at a distance from the reference position (L). is there. These instruction displays are instruction displays to positions on a straight line connecting the reference positions, and the movement ranges of the instruction displays are set so as not to overlap.

  Specifically, in the screen display of FIG. 3, the reference position of the engine speed bar display is the left end of the instruction unit 41, and the maximum extension position of the instruction display in the engine speed bar display is the right end of the instruction unit 41. is there. That is, the engine speed bar display is expanded by sequentially turning on the indicator 41 from the left end of the screen toward the right as the engine speed increases, and the maximum extension position is indicated by the indicator 41. The right end of On the other hand, the reference position of the gear ratio bar display is the right end of the instruction unit 42, and the maximum extension position of the instruction display in the gear ratio bar display is the left end of the instruction unit 42. In other words, the gear ratio bar display expands by sequentially lighting the indicator 42 from the right end side to the left side of the screen as the gear ratio increases, and the maximum extension position is the left end of the indicator 42. It becomes.

Thus, the engine speed bar display and the gear ratio bar display are displayed so that the direction of increase / decrease of the value is different. That is, as shown in FIG. 3, the engine speed is displayed from 0 [rpm] to 7000 [rpm] so as to increase from the left side to the right side with respect to the front of the display screen, and the gear ratio is changed from the right side to the left side. In order to increase, it is displayed from “L” indicating a low value to “H” indicating a high value.

  The instruction display is performed by changing the display mode of the instruction units 41 and 42 provided at regular intervals on the straight line. That is, the display mode of the instruction units 41 and 42 existing from each reference position to the position of the instruction display is changed. Here, as the change in the display mode of the instruction units 41 and 42, in this example, the indication units 41 and 42 are turned on / off. However, the present invention is not limited to this. It may be. In the example of FIG. 3, in the engine speed bar display, among the plurality of instruction units 41, the portion 41 a is in the lit state and the remaining portion 41 b is in the unlit state. In the gear ratio bar display, among the plurality of instruction units 42, the portion 42a is in the lit state and the remaining portion 42b is in the unlit state.

  This makes it easier for the driver to understand the change in the magnitude of each value from each reference position to the indication display position. For example, it is possible to easily grasp the magnitudes of the values of the engine speed and the gear ratio from the number of instruction units 41 and 42 whose display modes are changed.

  Arrows 43 and 44 indicating the direction in which the fuel consumption state is improved are also arranged above the engine speed bar display and the gear ratio bar display, respectively. The engine speed and the gear ratio as a plurality of values that change as the vehicle travels increase in fuel efficiency as the value increases, and improve as the value decreases. In this example, as shown in FIG. The bar display is displayed in such a manner that the fuel consumption improves as the current value of the bar display moves in the direction of arrows 43 and 44. Therefore, as shown in the example of FIG. 3, the degree of eco-driving can be easily grasped as the size of the interval between the turn-off display areas 41b and 42b. In addition, although the turn-off display areas 41b and 42b are in a turn-off state, the rectangular frames of the instruction units 41 and 42 are displayed, and thus the degree of eco-driving can be determined by the number of rectangular frames.

  Next, display control processing of the display device 20 of the present embodiment for realizing the display mode as described above will be described with reference to FIG. In this example, for example, real-time fluctuations in engine speed and gear ratio are represented as a plurality of values by a display image in the form of a bar graph. FIG. 4 is a flowchart illustrating an example of the display control process of the display device according to the first embodiment. This display control process is realized by the CPU 21b executing a control program stored in the ROM 21c.

  When the state of the ignition switch is acquired from the vehicle ECU via the OBDII adapter 13 and the ignition switch is turned on (step S11), the CPU 21b starts processing and proceeds to step S12. In step S12, the CPU 21b obtains the current engine speed and vehicle speed values from the vehicle ECU via the OBDII adapter 13. Subsequently, in step S13, the CPU 21b, based on the final reduction ratio and the outer diameter of the tire, A gear ratio is calculated from the acquired engine speed and vehicle speed value. The speed ratio is calculated by the following equations (1) and (2).

Axle rotation speed = vehicle speed / tire outer diameter (1)
Gear ratio = rotational speed / (axle rotational speed * final reduction ratio) (2)

An example calculation is as follows:
When the speed is 60 [km / h], the engine speed is 2000 [rpm], the final reduction ratio is 5.0, and the tire outer diameter is 2.0 [m], the following calculation is performed. It is assumed that the tire outer diameter in this example is a tire width of 195 [mm], a flatness ratio of 65 [%], and 15 inches.

Speed per minute = 60 * 1000/60 = 1000 [m / min]
Axle speed / min = 1000/2 = 500
Gear ratio = 2000 / (5 * 500) = 0.8

In the next step S14, the CPU 21b codes the engine speed acquired in step S12 and the gear ratio calculated in step S13.
Specifically, with respect to the engine speed, the range from 0 [rpm] to 7000 [rpm] is equally divided into 15 sections according to the number of instruction units 41 in FIG. 3, for example, and the code data for each section. Is allocated. Similarly, with respect to the gear ratio, the range from “L” to “H” is equally divided into 15 sections, and code data is assigned to each section. Here, the code data is data for identifying each division, and may be, for example, number data, symbol data, numerical data, or data combining these.

To describe a specific example, when the engine speed is equally divided into 15 sections from 0 [rpm] to 7000 [rpm], the first section is from 467 [rpm] to 933 from 0 [rpm] to 466 [rpm]. [Rpm] is the second division, and thereafter, the third division to the fifteenth division are equally divided. However, the remainder shall be included in the 15th division. For example, code data “A001” is assigned to the first division, code data “A002” is assigned to the second division, and thereafter, code data is assigned in ascending order from the third division to the fifteenth division. . The gear ratio is also equally divided into 15 sections from the minimum value to the maximum value. For example, code data “B001” is assigned to the first section, code data “B002” is assigned to the second section, and so on. The code data is assigned in ascending order from the third section to the fifteenth section.

The relationship between these classifications and code data is stored in advance in the ROM 21c as a data table. The CPU 21b applies the current engine speed acquired in step S12 to the data table and converts it into corresponding code data. Similarly, the gear ratio calculated in step S13 is also converted into corresponding code data. The CPU 21b writes the code data corresponding to the current value thus obtained in the RAM 21d, and proceeds to step S15.

In step S15, the CPU 21b displays one bar graph form corresponding to the engine speed bar display and the gear ratio bar display described above based on the code data corresponding to the current value obtained in step S14. Generate image data.
More specifically, in the control program stored in the ROM 21c, the engine speed bar display is turned on from the “0” side to the number of the instruction unit 41 corresponding to each code data. Control processing such as whether to do is programmed. Specifically, for example, if the current value of the engine speed is in the range of the second segment from 467 [rpm] to 933 [rpm], the code data “A002” is designated. As a result, the instruction unit 41 is turned on from the first to the second at the left end, and is turned off from the remaining third to the fifteenth at the right end. Similarly, with respect to the gear ratio bar display, control processing is programmed such as the number of indication units 42 from the “L” side to the lighting state corresponding to each code data. Specifically, for example, if the current shift value is within the range of the fifth section, code data “B005” is designated. As a result, the first to fifth items on the right end of the instruction unit 42 are turned on, and the remaining six items to the fifteenth item on the left end are turned off.

  Thus, according to the control program, the CPU 21b turns on the instruction units 41 and 42 according to the code data corresponding to the current value and turns off the instruction units 41 and 42 having a value larger than the current value. Perform lighting control. This lighting control is performed when the CPU 21b issues a display command to the graphic chip 21e.

  In subsequent step S16, the graphic chip 21e performs display processing of a display image in the form of a bar graph based on the display command. That is, the display image data for one bar graph form corresponding to the above-described engine speed bar display and gear ratio bar display is once rendered in the graphic memory 21f and then displayed under the control of the graphic chip 21e. The image is displayed on the display unit 32 via the drive circuit 31.

  Then, the CPU 21b repeatedly executes the processes from step S12 to step S16 until the ignition switch is turned off (step S17). Here, whether or not the ignition switch is in the OFF state is determined by acquiring the state of the ignition switch from the vehicle ECU via the OBDII adapter 13. The processes from step S12 to step S16 are repeated at predetermined time intervals (for example, about 200 ms) that the driver can recognize that the driving operation of the driver is reflected in real time, and the display is sequentially updated. .

  As described above, in the display device 20 according to the present embodiment, for example, the engine speed and the gear ratio are displayed as a plurality of values that change as the vehicle travels, and each value can be visually recognized by the driver. Control for displaying on the display unit 32 visible from inside the vehicle is performed so as to be visible as a position corresponding to the size of the vehicle. At that time, the degree of eco-driving is determined as the degree of quality of the state relating to the running of the vehicle, and the distance between the positions corresponding to the magnitude of each value (in the example of FIG. 3, the unlit display areas 41b and 42b are matched. Control to display as indicated by (interval).

By such display control, the display control system of the first embodiment has the following advantages.
(1) The driver visually recognizes, for example, the engine speed and the gear ratio as a plurality of values that change as the vehicle travels, and the position according to the magnitude of each value so that the change in each value can be visually recognized. In addition, it is possible to easily grasp the degree of eco-driving as the degree of quality of the state relating to the traveling of the vehicle from the size of the interval between the positions that change as the vehicle travels. For example, when driving, it is necessary to always look at the situation in front of and around the vehicle, and the display unit 32 cannot be stared. According to such a configuration, the driver looks at the display unit 32. As a result, the engine speed and the ratio of the gear ratio can be visually recognized and the change can be visually recognized, and the degree of eco-driving can be easily set as the distance between the unlit display areas 41b and 42b as shown in the example of FIG. Can grasp.

  (2) Since the positions corresponding to the engine speed and the speed ratio are displayed so as not to overlap each other, the visibility of the values of the engine speed and the speed ratio is further improved. Thereby, the driver can visually recognize the magnitudes of the values of the engine speed and the gear ratio without staring at the display unit 32, and can easily grasp the degree of eco-driving.

  (3) In a vehicle equipped with a continuously variable transmission, for example, whether the speed change that occurs when the accelerator is depressed as one driving operation is a speed change caused by a change in the speed change state of the continuously variable transmission. Although it is difficult for the driver to recognize whether it is a speed change due to a change in the number of revolutions given to the transmission, according to the display configuration as in this embodiment, it is easy to determine which value changes. From the size of the displayed position interval, for example, the degree of eco-driving can be easily determined as the degree of quality of the state relating to traveling.

-Example 2-
In this embodiment, in the bar graph display mode of the first embodiment, the instantaneous fuel consumption and the average fuel consumption can be displayed in a bar graph in addition to the engine speed and the gear ratio.
FIG. 5 is a screen display diagram illustrating an example of a bar graph display mode according to the second embodiment. Elements common to those in FIG. 3 are denoted by the same reference numerals, and description thereof is omitted.
In this embodiment, instantaneous fuel efficiency and average fuel efficiency are used as values evaluated at different predetermined times. As a plurality of values that change as the vehicle travels, the instantaneous fuel efficiency is a value that is recognized as a value indicating a state related to real-time travel for the driver, and the average fuel efficiency indicates a state related to cumulative travel. A value that is recognized as a value.

  The display image in the form of a bar graph illustrated in FIG. 5 is displayed as a position corresponding to the magnitude of instantaneous fuel consumption (“instant fuel consumption” in addition to the engine speed bar display and the gear ratio bar display shown in FIG. 3. And a display as a position corresponding to the average fuel consumption (referred to as “average fuel consumption bar display”).

  In the instantaneous fuel consumption bar display, a plurality of instruction units 51 (15 in the example of FIG. 5) having the same width (size in the vertical direction of the screen) composed of a substantially rectangular display area are arranged on a vertical line at regular intervals. . Similarly, a plurality of instruction units 52 (15 in the example of FIG. 5) having the same width as the respective instruction units 51 are arranged on the vertical line at regular intervals corresponding to the average fuel consumption bar display. These instantaneous fuel efficiency bar display and average fuel efficiency bar display are arranged on a vertical straight line facing each other with a predetermined interval. This empty interval is set wider than the interval between the instruction units 51 and 52 in each bar display (in the example of FIG. 5, about eight of the instruction units 51 or 52). It is set wider than the height of the instruction units 51 and 52 (size in the horizontal direction of the screen). Thereby, the instantaneous fuel consumption bar display and the average fuel consumption bar display can be arranged on the vertical straight line without overlapping.

Then, the engine speed bar display and the gear ratio bar display and the horizontal array bar graph composed of the above-mentioned empty areas, and the instantaneous fuel economy bar display and average fuel economy bar display and the vertical array bar graph composed of the above-mentioned empty areas intersect. To be arranged. In other words, if the central axes of the horizontal array bar graph and the vertical array bar graph are straight lines, they are arranged so as to intersect at right angles in the positions where the straight lines are equally divided, that is, in the empty areas. Thus, the engine speed bar display, the gear ratio bar display, the instantaneous fuel consumption bar display, and the average fuel consumption bar display are arranged without overlapping each other.

  The instantaneous fuel consumption bar display is an instruction display to a position at a distance from the reference position (0 [km / L]), and the average fuel consumption bar display is a distance from the reference position (1 [km / L] or less). It is an indication display to the position of. These instruction displays are instruction displays to positions on a straight line connecting the reference positions, and the movement ranges of the instruction displays are set so as not to overlap.

  Specifically, in the screen display of FIG. 5, the reference position of the instantaneous fuel consumption bar display is the lower end of the instruction unit 51, and the maximum extension position of the instruction display in the instantaneous fuel consumption bar display is the upper end of the instruction unit 51. That is, as the instantaneous fuel consumption increases, the instantaneous fuel consumption bar display is expanded by sequentially turning on the instruction unit 51 from the lower end side to the upper side of the screen, and the maximum extension position is the upper end of the instruction unit 51. It becomes. On the other hand, the reference position of the average fuel consumption bar display is the upper end of the instruction unit 52, and the maximum extension position of the instruction display in the average fuel consumption bar display is the lower end of the instruction unit 52. That is, as the average fuel consumption increases, the average fuel consumption bar display is expanded by sequentially turning on the instruction unit 52 from the upper end side to the lower side of the screen. It becomes the lower end.

  The instruction display is performed by changing the display mode of the instruction units 51 and 52 provided at regular intervals on the straight line. That is, the display mode of the instruction units 51 and 52 existing from the respective reference positions to the instruction display positions is changed. Here, as the change in the display mode of the instruction units 51 and 52, in this example, the indication units 51 and 52 are turned on / off, but the present invention is not limited to this. It may be. In the example of FIG. 5, in the instantaneous fuel consumption bar display, among the plurality of instruction units 51, the portion 51 a is in the lit state and the remaining portion 51 b is in the unlit state. Further, in the average fuel consumption bar display, among the plurality of instruction units 52, the portion 52a is in the lit state and the remaining portion 52b is in the unlit state.

This makes it easier for the driver to understand the change in the magnitude of each value from each reference position to the indication display position. For example, the magnitude of each value of the instantaneous fuel consumption and the average fuel consumption can be easily grasped from the number of instruction units whose display modes are changed.
Arrows 53 and 54 indicating the direction in which the fuel economy state is improved are also arranged on the side of the instantaneous fuel efficiency bar display and the average fuel efficiency bar display, respectively. The instantaneous fuel economy and the average fuel economy indicate that the fuel economy is better as the value becomes larger. In this example, as shown in FIG. 5, if the current value of the bar graph display shifts in the direction of arrows 53 and 54. Displayed to improve fuel efficiency. Moreover, the display as a position according to the magnitude of the instantaneous fuel consumption and the average fuel consumption is displayed so that the increase / decrease directions are different from each other. That is, as shown in FIG. 5, the instantaneous fuel consumption is displayed from “1 or less” to “100 or more” so as to increase from the upper side to the lower side with respect to the front of the display screen, and the average fuel consumption is from the lower side to the upper side. It is displayed from “0” to “50” so as to increase.

  Next, display control processing of the display device 20 of the present embodiment for realizing the above display mode will be described with reference to FIG. FIG. 6 is a flowchart illustrating the display control process of the display device 20 according to the second embodiment. This display control process is realized by the CPU 21b executing a control program stored in the ROM 21c.

  When the state of the ignition switch is acquired from the vehicle ECU via the OBDII adapter 13 and the ignition switch is turned on (step S21), the CPU 21b starts processing and proceeds to step S22. In step S22, the CPU 21b acquires the current engine speed and vehicle speed values from the vehicle ECU via the OBDII adapter 13, and also acquires the ignition cycle and fuel injection amount values.

Subsequently, in step S23, the CPU 21b calculates the gear ratio from the values of the engine speed and the vehicle speed by the same calculation method as in step S13 of FIG.
In the next step S24, the CPU 21b calculates the instantaneous fuel consumption by, for example, 1 second by a known calculation method based on the travel distance obtained from the vehicle speed acquired in step S22 and the fuel injection amount between the travel distances. As in the following (for example, 0.2 seconds), it may be calculated based on the travel distance during a very short time compared to the average fuel consumption and the fuel injection amount during that time. Further, based on the obtained instantaneous fuel consumption, for example, the average fuel consumption from the time when the ignition switch is turned on until the present time is calculated, and the process proceeds to step S25.

  In step S25, the CPU 21b codes the engine speed acquired in step S22, the gear ratio calculated in step S23, and the instantaneous fuel efficiency and average fuel efficiency calculated in step S24. Specifically, encoding is performed by the same method as that described in step S14 in FIG. The CPU 21b writes the code data corresponding to the current value thus obtained in the RAM 21d, and proceeds to step S25.

  In step S26, the CPU 21b, based on the code data obtained in step S25, displays the bar corresponding to the above-described engine speed bar display, gear ratio bar display, instantaneous fuel consumption bar display, and average fuel consumption bar display. Display image data in the form of a graph is generated. Specifically, display image data for one sheet is generated by a method similar to that described in step S15 in FIG.

  In subsequent step S27, the graphic chip 21e performs display processing of a display image in the form of a bar graph based on a display command from the CPU 21b. That is, the display image data for one bar graph form corresponding to the above-described engine speed bar display, gear ratio bar display, instantaneous fuel efficiency bar display, and average fuel efficiency bar display is once drawn in the graphic memory 21f. Then, the image is displayed on the display unit 32 via the display drive circuit 31 under the control of the graphic chip 21e.

  Then, the CPU 21b repeatedly executes the processes from step S22 to step S27 until the ignition switch is turned off (step S28). That is, the processing from step S22 to step S27 is repeated at predetermined time intervals that allow the driver to recognize that the driving operation of the driver is reflected in real time, and the display is sequentially updated.

The second embodiment has the following advantages in addition to the advantages of the first embodiment.
The driver can visually recognize the instantaneous fuel consumption and the average fuel consumption as positions corresponding to the magnitudes of these values so that changes in these values can be visually recognized, and the interval between the positions of these values (FIG. 5). In this example, from the size of the interval between the turn-off display areas 51b and 52b), for example, the degree of quality of the fuel consumption can be easily grasped as the degree of quality of the state relating to the running of the vehicle. In other words, the quality of fuel consumption based on both the instantaneous fuel efficiency recognized as a value indicating a state relating to real-time driving for the driver and the average fuel efficiency indicating the cumulative driving state that changes as the vehicle travels. Can be easily grasped from the size of the interval between the positions of these values.

-Example 3-
In the bar graph display mode of the second embodiment, the present embodiment displays the instantaneous fuel consumption state with respect to the average fuel consumption so as to be comparable.
FIG. 7 is a screen display diagram illustrating an example of a bar graph display mode according to the third embodiment, and FIGS. 8A, 8B, and 8C show details of the bar graph display mode of FIG. FIG. In these drawings, elements common to those in FIG. 5 are denoted by the same reference numerals, and description thereof is omitted.
In the present embodiment, in the display image in the bar graph form shown in FIG. 5, a threshold line 61 indicating the current value of the average fuel consumption is displayed in parallel with the indication unit 51 of the instantaneous fuel consumption bar display. is there. Therefore, the threshold line 61 moves in the vertical direction according to the current value of average fuel consumption. If the current instantaneous fuel consumption is the same or smaller than the average fuel consumption (the upper end of the lighting display area 51a is equal to or less than the threshold line 61), the lighting display area 51a of the instantaneous fuel consumption bar display is shown in FIG. Displayed in blue as shown in (a). If the current instantaneous fuel consumption is slightly larger than the average fuel consumption (the upper end of the lighting display area 51a exceeds the threshold line 61, for example, up to two instruction units), the lighting display area 51a is yellow as shown in FIG. Is displayed. Then, if the current instantaneous fuel consumption is considerably larger than the average fuel consumption (the upper end of the lighting display area 51a is the threshold line 61, for example, three or more indicating parts), the lighting display area 51a is red as shown in FIG. Is displayed.

  Next, display control processing of the display device 20 of the present embodiment for realizing the above display mode will be described with reference to FIGS. FIG. 9 is a flowchart showing the instantaneous fuel consumption color-specific display process in the display control process of the display device 20 according to the third embodiment. In this instantaneous fuel consumption color-specific display process, the CPU 21b executes a control program stored in the ROM 21c. It is realized by doing.

  The CPU 21b performs processing similar to the processing from step S21 to step S25 in FIG. 6, and then in step S26, based on the code data obtained in step S25, the above-described engine speed bar display and gear ratio are described. Display image data in the form of a bar graph corresponding to the bar display for instantaneous fuel consumption, the bar display for instantaneous fuel consumption, and the bar display for average fuel consumption is generated. This generation is performed by a method similar to that described in step S15 in FIG. Furthermore, the display image data of the threshold line 61 indicating the current value of the average fuel consumption, which is displayed in parallel with the indication unit 51 of the instantaneous fuel consumption bar display, is also generated. Then, in the generation of the display image data of the instantaneous fuel consumption bar display, display processing for each instantaneous fuel consumption color for displaying the instantaneous fuel consumption by color corresponding to the threshold line 61 is performed.

  This instantaneous fuel consumption color-specific display process is performed, for example, according to the process flow shown in FIG. That is, first, in step S41, the CPU 21b compares the current instantaneous fuel consumption with the average fuel consumption to determine whether or not the instantaneous fuel consumption is equal to or less than the average fuel consumption. If it is equal to or less than the average fuel efficiency, the process proceeds to step S42, and the lighting display area 51a of the instantaneous fuel efficiency bar display is displayed in blue as shown in FIG. If the instantaneous fuel consumption exceeds the average fuel consumption, the process proceeds to step S43 to determine whether or not the instantaneous fuel consumption greatly exceeds the average fuel consumption. If it does not greatly exceed, the process proceeds to step S44, the lighting display area 51a is displayed in yellow as shown in FIG. 8B, and the present process is terminated. If so, the process proceeds to step S45 where the lighting display area 51a is displayed in red as shown in FIG.

When the display image data generation process for one sheet including the instantaneous fuel consumption color display process is completed, the CPU 21b advances the process to step S27.
In step S27, the graphic chip 21e performs display processing of a display image in the form of a bar graph based on a display command from the CPU 21b. That is, one sheet obtained by adding a threshold line 61 display to the bar graph form corresponding to the above-described engine speed bar display, gear ratio bar display, color-specific instantaneous fuel consumption bar display, and average fuel consumption bar display. The display image data for one minute is once drawn in the graphic memory 21f and then displayed on the display unit 32 via the display drive circuit 31 under the control of the graphic chip 21e.

  Then, the CPU 21b repeatedly executes the processes from step S22 to step S27 until the ignition switch is turned off (step S28). That is, the processing from step S22 to step S27 is repeated at predetermined time intervals that allow the driver to recognize that the driving operation of the driver is reflected in real time, and the display is sequentially updated.

  According to the third embodiment, in addition to the advantages of the second embodiment described above, the instantaneous fuel consumption as a value evaluated in a relatively short time with respect to the average fuel consumption as a value evaluated in a relatively long time. Based on the degree of deviation, the instantaneous fuel consumption can be displayed, for example, by color, and the driver can more easily grasp the degree of eco-driving.

Example 4
In the present embodiment, as a plurality of values that change as the vehicle travels, for example, the magnitude of the speed ratio value is displayed by a change in the shape of the continuously variable transmission, and as a plurality of values, for example, the engine speed, the axle The magnitude of the value of the rotation number is displayed by an animation operation.
10A and 10B are screen display diagrams illustrating an example of an animation display mode according to the fourth embodiment.
The display images of the animation display modes illustrated in FIGS. 10A and 10B have a top view display area 70 that simulates the change in the gear ratio of the continuously variable transmission by the state change of the gear portion 71 of the continuously variable transmission. I have. Further, a side view display area 80 is arranged in parallel corresponding to the top view display area 70. The side view display area 80 simulates fluctuations in the value of the engine rotation speed by the rotation speed of the rotation area 73 indicating a gear joined to the engine drive shaft 72, and further displays fluctuations in the value of the axle rotation speed. 74 is an animation display area imitating the rotation speed of the rotation area 75 indicating the gear joined to 74.

Then, in the top view display area 70 and the side view display area 80, the shape shown in FIG. 10A shows a state where the gear ratio is high (close to the first speed) as shown in FIG. A continuous change in display shape to a shape representing a low gear ratio (distant from the first gear) state shown in (b), or from the shape shown in FIG. 10 (b) to the shape shown in FIG. 10 (a). The display shape is continuously changed.
In the present embodiment, in addition to the configuration of the third embodiment described above, a screen displayed by an animation operation is provided. The screen of the third embodiment (FIGS. 5 and 7) and the screen displayed by the animation operation (FIG. 10) are simultaneously displayed at different positions on the same screen.

Next, a display control process of the display device 20 of the present embodiment for realizing the display mode will be described with reference to FIG.
FIG. 11 is a flowchart illustrating the display control process of the display device 20 according to the fourth embodiment. This display control process is realized by the CPU 21b executing a control program stored in the ROM 21c.

  When the ignition switch is turned on (step S51), the CPU 21b starts processing and proceeds to step S52. In step S52, the CPU 21b acquires the current engine speed and vehicle speed values in the same manner as in step S12 in FIG. 4, and subsequently in step S53, the CPU 21b performs the same operation as in step S13 in FIG. Calculate the speed and gear ratio.

  In the next step S54, the CPU 21b codes the acquired engine speed, the calculated axle speed, and the gear ratio. Specifically, as for the engine speed, for example, the range from 0 [rpm] to 7000 [rpm] matches the number of a plurality of patterns (described later) used to display the rotation area 73 shown in FIG. The code data is assigned to each division. Similarly, code data is assigned to the axle rotation speed. Regarding the gear ratio, a range from a low value “L” to a high value “H” is divided according to the number of a plurality of patterns (described later) used for display in the top view display area 70, and for each division. Code data is allocated. These are stored in advance in the ROM 21c as a data table.

The CPU 21b applies the acquired current engine speed to the data table and converts it into corresponding code data. Similarly, the calculated axle rotation speed and gear ratio are also converted into corresponding code data. The CPU 21b writes the code data corresponding to the current value thus obtained in the RAM 21d, and proceeds to step S55.
In step S55, the CPU 21b generates display image data for one sheet of the display form shown in FIG. 10 described above, based on the code data corresponding to the current value obtained in step S54.

  More specifically, in the top view display area 70 and the side view display area 80, for example, the shape shown in FIG. 10A is continuously changed from the shape shown in FIG. 10A to the shape shown in FIG. The display shape is changed. Among the continuous image patterns displayed along with the continuous shape change, a plurality of patterns are selected step by step and stored in advance. Further, in the rotation areas 73 and 75 of the side view display area 80, a continuous display change in which the pattern of the fan-shaped pair moves in the rotation direction is performed in accordance with fluctuations in the values of the engine speed and the axle speed. Among the continuous image patterns displayed along with the continuous display change, a plurality of patterns are selected and stored in advance.

  In the control program stored in the ROM 21c, the top view display area 70 and the side view display area 80 are selected from among a plurality of patterns corresponding to individual code data corresponding to the change in the speed ratio value. Control processing such as which pattern is used is programmed. As for the animation display areas of the rotation areas 73 and 75, a plurality of patterns are displayed in a frame-by-frame manner. However, a plurality of patterns corresponding to individual code data corresponding to fluctuations in the values of the engine speed and the axle speed A process for controlling the degree of the frame advance amount (pattern shift amount) is programmed.

The CPU 21b performs lighting control according to such a control program. This lighting control is performed when the CPU 21b issues a display command to the graphic chip 21e.
In the subsequent step S56, the graphic chip 21e performs display image display processing as shown in FIG. 10 based on the display command. That is, the display image data for one sheet in the above-described form is once drawn in the graphic memory 21f and then displayed on the display unit 32 via the display drive circuit 31 under the control of the graphic chip 21e.

  Then, the CPU 21b repeatedly executes the processes from step S52 to step S56 until the ignition switch is turned off (step S57). That is, the processing from step S52 to step S56 is repeated at a predetermined time interval that allows the driver to recognize that the driving operation of the driver is reflected in real time, and the display is updated sequentially. With respect to the animation display areas 73 and 75, fluctuations in the values of the engine speed and the axle speed can be expressed by the speed of rotation of the rotation areas 73 and 75.

According to the present embodiment, the driver can visually recognize the magnitude of the speed ratio as a plurality of values that change as the vehicle travels, and can also recognize the values of the engine speed and the axle speed. Can be grasped by an animation display of a part accompanied by a movement related to each value.
In the above description, the screen of the third embodiment (FIGS. 5 and 7) and the screen displayed by the animation operation (FIG. 10) are simultaneously displayed at different positions on the same screen. Instead of displaying, you may switch and display.

Is lit on. Further, in a state where the gear ratio is low and the engine speed is large, as shown in FIG. 12 (b), the circular area 81 is largely missing and is displayed in a crescent shape, and the direction of the arrow in the arrow area 82 is clockwise. It is lit and displayed in a shape that has been greatly rotated.

In the circular area 81, the shape changes continuously from the shape shown in FIG. 12 (a) to the shape shown in FIG. 12 (b) as the speed ratio changes, and in the arrow area 82, the engine speed changes. The display shape is changed, or the display shape is continuously changed from the shape shown in FIG. 12B to the shape shown in FIG.
This embodiment includes a needle meter display mode screen in addition to the configuration of the third embodiment described above. The screen of the third embodiment (FIGS. 5 and 7) and the needle meter display mode screen (FIG. 12) are simultaneously displayed at different positions on the same screen.

  Next, regarding the display control processing of the display device 20 of the present embodiment for realizing the display mode, the top view display area 70 and the side view display area 80 described with reference to FIG. For example, the display control method is the same as the display control method related to the continuous display shape change from the shape shown in FIG. 10A to the shape shown in FIG. That is, the display object is merely changed to a circular area 81 and an arrow area 82, and other display controls are the same.

According to the present embodiment, in addition to the advantages of the third embodiment, the driver can easily recognize the speed ratio and the value of the engine speed as a plurality of values that change as the vehicle travels. it can.
In the above description, the screen of the third embodiment (FIGS. 5 and 7) and the screen of the needle meter display mode (FIG. 12) are simultaneously displayed at different positions on the same screen. Instead of displaying, you may switch and display.

As shown in FIG. 13, the magnitude of the engine speed is displayed in the vertical axis direction, and the magnitude of the vehicle speed is displayed in the horizontal axis direction. Lines L1 and L2 in the figure indicate the maximum and minimum speed ratios calculated from the vehicle specification table. A curve CL on the left side of the line L1 indicates a change in the gear ratio corresponding to the slip of the torque converter (corresponding to the slip of the clutch of the manual vehicle) when the vehicle starts running. If there is no slip of the torque converter, the gear ratio basically changes in the range inside the lines L1 and L2 (WO in FIG. 13). In the example of FIG. 13, the tire has an outer diameter of 724 mm (225/65 R17), a gear ratio of 2.396 to 0.428, and a final reduction ratio of 5.470.
In this embodiment, in addition to the configuration of the third embodiment described above, a screen for displaying a graph of the gear ratio log is provided. The screen of the third embodiment (FIGS. 5 and 7) and the screen for displaying the graph of the gear ratio log (FIG. 13) are simultaneously displayed at different positions on the same screen.

Next, the display control processing of the display device 20 of the present embodiment will be described with reference to FIG. FIG. 14 is a flowchart illustrating the display control process of the display device 20 according to the sixth embodiment. This display control process is realized by the CPU 21b executing a control program stored in the ROM 21c.
As shown in FIG. 14, the processing from step S61 to step S63 is the same as the processing from step S11 to step S13 in FIG. In step S64, a gear ratio log is obtained based on the calculated gear ratio, and in step S65, a graph as shown in FIG. 13 is displayed using the engine speed, vehicle speed, and gear ratio log values.

  Specifically, the graphic chip 21e displays a graph while keeping the change of the gear ratio log in accordance with the display command of the CPU 21b for displaying the graph as shown in FIG. The display image data for one sheet in the above-described graph form is once drawn in the graphic memory 21f and then displayed on the display unit 32 via the display drive circuit 31 under the control of the graphic chip 21e.

  Thereafter, the CPU 21b repeatedly executes the processes from step S62 to step S65 until the ignition switch is turned off (step S66). That is, the processes from step S62 to step S65 are repeated at predetermined time intervals that allow the driver to recognize that the driving operation of the driver is reflected in real time, and the display is sequentially updated.

  According to the fifth embodiment, the change in each of these values and the shift state can be grasped by the graph of the gear ratio log with the engine speed and the vehicle speed as different axes. In the above description, the screen of the third embodiment (FIGS. 5 and 7) and the screen for displaying the gear ratio log graph (FIG. 13) are simultaneously displayed at different positions on the same screen. However, the display may be switched instead of displaying simultaneously.

-Modification-
The present invention is not limited to the illustrated embodiment, and various modifications are possible. Examples of such modifications include the following.

  (1) Although the display control system is a display device mounted on a vehicle in each of the above embodiments, the display control system includes a case where the display control system is configured by a server or the like outside the vehicle.

  (2) In each of the above embodiments, the value of the sensor connected to the vehicle ECU is used for the engine speed and the vehicle speed data. However, the sensor value may be a value obtained by performing a predetermined process. . The value processed by performing this predetermined process may be a value obtained from a value of one sensor or the like, or may be a value obtained from values of a plurality of sensors or the like. Moreover, it is good also as a value based on the value acquired from the sensor etc. which were attached in the vehicle accompanying the display control system. The sensor or the like retrofitted in the vehicle accompanying the display control system may be configured to be stored in one housing together with a part having at least some components of the display control system.

  (3) In the above embodiment, the engine speed, the vehicle speed, the gear ratio, the instantaneous fuel consumption, and the gear ratio log are taken as a plurality of values that change as the vehicle travels. It may be another value recognized as a value indicating. The value recognized as a value indicating a state relating to real-time driving for the driver may be, for example, a value that is updated at intervals at which the driver can recognize that the driving operation of the driver is reflected in real time. The interval at which the driver can recognize that the driving operation of the driver is reflected in real time usually varies depending on the type of the value. If this value is, for example, the accelerator opening, it is necessary to update at a time interval necessary for the change in the accelerator opening, and the order of the update interval is, for example, several hundred ms or less. On the other hand, if the value is, for example, the temperature of engine cooling water, it is set to about several minutes or less, for example.

  (4) In the first, second, and third embodiments, a value recognized as a value indicating a state related to real-time driving for the driver is set as the engine speed, the gear ratio, or the instantaneous fuel consumption, and the vehicle travels. The value recognized as a value indicating the state relating to the changing cumulative running is defined as the average fuel consumption, but these values are not limited to the above.

  (5) In the first, second, and third embodiments, it can be seen that the fuel efficiency increases as the interval between the positions corresponding to the engine speed and speed ratio, or the instantaneous fuel efficiency and the average fuel efficiency (current value) increases. I did it. On the other hand, you may comprise so that a fuel consumption may be improved, so that the space | interval of the positions according to the magnitude | size of each of these values becomes narrow. Specifically, in the screen display of FIGS. 3, 5, and 7, the engine speed is displayed from 0 [rpm] to 7000 [rpm] so as to increase from the right side to the left side with respect to the front of the display screen. The gear ratio is displayed from “L” to “H” so as to increase from the left side to the right side. The instantaneous fuel consumption is displayed from “0” to “50 or more” so as to increase from the upper side to the lower side with respect to the front of the display screen, and the average fuel consumption is “1 or less” so as to increase from the lower side to the upper side. ”To“ 100 or more ”.

  (6) In the first, second, and third embodiments, the current value of the bar graph display is displayed in the direction of the arrows 43, 44, 53, and 54 so that the fuel economy is improved. In the screen display of FIG. 7, the direction of these arrows may be changed in the opposite direction, and the current value of the bar graph display may be displayed in the direction of the arrow so that the fuel consumption is deteriorated. With such a display, it can be easily understood that the fuel efficiency is worsened as the interval between the positions corresponding to the magnitude of each value (current value) becomes narrower.

  (7) The display as the position corresponding to the magnitude of each value may be a form in which the magnitude of each value is indicated by the motion of a moving image of a different display object. As a result, since the magnitude of each value is indicated by the motion of the moving image of the different display object, it is possible to easily recognize the value indicating the value from the moving image of the display object. For example, in the screen display of FIG. 3, the gear ratio side is set as a gear mark and the engine speed side is set as a piston mark for each indicator portion of the bar that is lit. In this way, it is easy to grasp the magnitude of the gear ratio from the number of lights on the gear mark, and it is easy to grasp the magnitude of the engine speed from the number of lights on the piston mark. The level of eco-driving can be easily grasped from the distance between both ends of the non-lighting portion between the two.

  (8) The position corresponding to the magnitude of each value may be obtained by putting each value in a predetermined function. For example, a position proportional to the value itself (for example, a linear function) may be used, or a position indicated by a value obtained by substituting the value into another predetermined function may be used.

  (9) The plurality of values that change as the vehicle travels are a plurality of values that are variable by automatic control of the vehicle based on the driver's one driving operation. You may make it provide the some value with which it is difficult to recognize whether the value is changing. As a result, when the driver performs one driving operation, it is possible to easily know the degree of quality of the state relating to traveling from the size of the interval between the values that are changed by the automatic control, and the variable is controlled by the automatic control. You can know the magnitude and change of values.

  (10) The value related to the control amount of the configuration for applying rotation to the continuously variable transmission is the engine speed in each of the above embodiments, but is not limited thereto, and is not limited to this value, such as the fuel flow rate, the intake manifold value, etc. May be.

  (11) The animation display according to the fourth embodiment may be performed together with or after the bar graph display according to the first embodiment. As a result, the driver can view the values of the engine speed and the gear ratio as a plurality of values that change as the vehicle travels, and the change according to each value can be visually recognized. As well as being able to easily grasp the degree of fuel efficiency as the degree of quality of the state related to the traveling of the vehicle from the size of the interval between the positions that change with the traveling of the vehicle, The magnitude of each value can be grasped by the animation display of the part accompanied by the movement related to each value.

  (12) The log graph display according to the sixth embodiment may be performed together with or after the bar graph display according to the first embodiment. As a result, the driver can change the values of the engine speed and the gear ratio, for example, as a plurality of values that change as the vehicle travels. As well as being able to easily grasp the degree of quality of the state relating to vehicle running from the size of the interval between positions that change with the vehicle running, The change of each value can be grasped by the graph.

  (13) The display mode of the instruction unit existing between the respective instruction displays is the same display mode, and the same display mode is the display mode of the instruction unit existing from each reference position to the position of the instruction display. It is good also as a different display mode. For example, in the screen display of FIG. 3, the unlit display areas 41b and 42b may be turned on and displayed in the same color (for example, blue). Further, the lighting display areas 41a and 42a may be displayed in different colors (for example, yellow and red) in a color different from that color. As a result, the magnitude of each value can be easily grasped, and the “degree of quality of the state relating to the traveling” can be easily grasped.

(14) The storage medium such as an SD card stores at least one of the engine speed and the gear ratio used for the display, the history of the instantaneous fuel consumption and the average fuel consumption, or the actual display content history. The stored data may be recorded in the same manner as the data acquired from the vehicle described in each embodiment and sequentially reproduced and displayed by a personal computer or a portable terminal. In this way, it is possible to easily confirm the degree of quality of the state related to the traveling of the vehicle after traveling with a personal computer or the like.

(15) As a combination of data to be displayed, for example, one selected from the following data may be used. For example, you may make it provide the function selected by a touchscreen and a display. The data includes "speed", "average speed", "maximum speed", "5-second speed", "average 5-second speed", "maximum 5-second speed", "rotation speed", "average rotation speed", "maximum rotation speed", "engine load". “Average load” “Maximum load” “Throttle opening” “Average throttle opening” “Maximum throttle opening” “Ignition timing” “Fuel level” “Inmani pressure” “MAF” “INJ” “Cooling water temperature” “Intake air” "Temperature" "Outside air temperature" "Remaining fuel" "Fuel flow" "Fuel consumption" "Lifetime fuel consumption" "Instant fuel consumption" "Current fuel consumption" "Lifetime fuel consumption" "Average fuel consumption" "Average fuel consumption general road" "Average fuel consumption expressway" “Running time” “Running time” “Idle time” “Idle ratio” “Running distance” “Lifetime running distance” “0-20 km / h acceleration time” “0-20 km / h average acceleration” “0-20 km / h” "Shortest acceleration" "0-40km / h acceleration time" "0- "0km / h average acceleration" "0-40km / h shortest acceleration" "0-60km / h acceleration time" "0-60km / h average acceleration" "0-60km / h shortest acceleration" "0-80km / h acceleration time “0-80 km / h average acceleration” “0-80 km / h shortest acceleration” “0-20 km / h running time” “20-40 km / h running time” “40-60 km / h running time” “60-80 km” / H travel time "," travel time of 80 km / h or more ", etc.

(16) For example, in the display configuration of FIG. 3, the right side instruction unit 42 is replaced with “speed ratio” to be “cooling water temperature”, the low cooling water temperature side is the left side, and the high cooling water temperature side is the right side. Then, the coolant temperature rises as the vehicle travels from a state where the coolant temperature at the start of travel is low. If the cooling water temperature is low, the engine speed may increase without stepping on the accelerator to raise the cooling water temperature due to air conditioner operation, etc., but the reference positions of the engine speed and the cooling water temperature respectively. Whether or not this state is present can be easily determined from the amount of displacement from the designated position to the designated position and the interval between the designated positions.
Further, for example, in the display configuration of FIG. 3, the right-side instruction unit 42 is replaced with “speed ratio” to be “motor rotation speed” in the hybrid vehicle, the motor rotation speed on the right side and the motor rotation speed on the high side. On the left side, the engine and motor speeds can be determined from the amount of displacement from each reference position to the indicated position, and the overall energy usage status can be easily determined from the distance between the specified positions. Can be. It can be seen at a glance that the wider the interval, the lower the overall energy usage, and the lower the interval, the higher the overall energy usage.

(17) Although the shape of each of the instruction units 41 and 42 is the same rectangular shape, it may be a different shape. In particular, it is better to make the shape gradually larger from the indication units 41 and 42 closer to the center to the periphery. For example, the upper and lower heights may be the same, and the left and right widths may be gradually increased. In this way, the display moves greatly from the reference position with a slight deterioration. Therefore, be careful of driving so as not to deteriorate even a little. Conversely, the shape may be made gradually smaller from the indication unit 41, 42 closer to the center to the periphery. In this way, it does not move so much from the reference position with a slight deterioration, but moves greatly from the reference position when it is operated to make it considerably worse. Therefore, it is useful for preventing driving that is considerably worsened.
