Hereinafter, embodiments of the display device according to the present invention will be described in detail with reference to the accompanying drawings. Needless to say, the present invention is not limited to the following examples, and various modifications can be made without departing from the spirit of the present invention.

The configuration of the display device according to the first embodiment of the present invention will be described with reference to FIGS. 1 and 2A to 2C.

As shown in FIG. 1, the hybrid vehicle 10 has a motor 11 (electric motor) and an engine 12 (internal combustion engine) as driving force sources for traveling. The motor 11 may be configured to drive the front wheels or the rear wheels, or a plurality of motors 11 may be provided to drive the front wheels and the rear wheels, respectively. Further, the engine 12 may be configured to drive the front wheels or the rear wheels, or may be configured to drive the front wheels and the rear wheels. The hybrid vehicle 10 may also include a generator (not shown) that is driven by the engine 12 to generate power.

The hybrid vehicle 10 has a traveling mode in which the engine 12 is stopped and traveling using the motor 11 (driving the drive wheels) is prioritized (priority is performed in the motor 11 over traveling in the engine 12). It has a mode (electric motor output mode) and a second mode (internal combustion engine output mode) in which the engine 12 is operated and the vehicle travels using the motor 11 and the engine 12 (drives drive wheels).

The hybrid vehicle 10 also includes an ECU (Electronics Control Unit) 20 that is a control unit. The ECU 20 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), an input/output circuit, and the like, is electrically connected to the motor 11 and the engine 12, and supplies electric power to the motor 11. The drive battery 13 to be supplied, a vehicle speed sensor 14 for detecting a vehicle speed, and an accelerator opening sensor 15 for detecting an accelerator opening are also electrically connected.

Therefore, a signal value (motor rotation speed, motor output, etc.) from the motor 11 and a signal value (ON/OFF, engine rotation speed, engine output, etc.) from the engine 12 are input to the ECU 20, and the battery 13 is further supplied. Signal values (SOC (State of Charge), battery output, etc.) and signal values of the vehicle speed sensor 14 and the accelerator opening sensor 15 are also input.

The hybrid vehicle 10 further includes a display device 30 that displays an output (travel output) related to traveling of the hybrid vehicle 10, and the display device 30 is electrically connected to the ECU 20. The traveling output of the hybrid vehicle 10 is obtained by performing an arithmetic processing on the basis of the signal value described above in the ECU 20, and the arithmetically operated value (traveling output) is input to the display device 30.

As shown in FIGS. 2A to 2C, the display device 30 has a circular instrument panel 31 in which a first region 32-1, a second region 33, and a third region 32-2 are arranged. In the following description, as a representation of the orientation on the instrument panel 31, the time of a clock with the uppermost position T of the instrument panel 31 at 0 o'clock (=12 o'clock) or the uppermost position T of the instrument panel 31 is 0. Either one or both of the angles defined as the position of ° (=360°) is used.

The first region 32-1 is a region that indicates the traveling output in the first mode when the engine 12 is stopped and the motor 11 is used for traveling, that is, about 270° in the outer peripheral portion on the instrument panel 31. Are arranged in a fan shape or an arc shape between the positions of 360° (9 o'clock to 12 o'clock). The 1st field 32-1 is provided with the 1st indicator 32A which changes according to the run output in the 1st mode.

The first display portion 32A is a level bar indicating a value corresponding to the traveling output in the first mode in the first area 32-1 (between the positions from 9 o'clock to 12 o'clock). Specifically, the first display unit 32A changes the length (length from the 9 o'clock position) of the strip-shaped figure according to the traveling output in the first mode, and the length of the strip-shaped figure ( The value corresponding to the traveling output in the first mode is indicated by the level bar by the end point (the position of the tip end) with the position at 9 o'clock as the starting point.

As described above, by using the first display unit 32A as the level bar, it is possible to more clearly inform the driver of the state when traveling without starting the engine 12 in the first mode. The property is improved.

As the traveling output in the first mode, for example, the motor rotation speed of the motor 11, the motor output of the motor 11, the battery output of the battery 13, the vehicle speed, the accelerator opening, and other outputs related to the motor 11 can be used.

In addition, the first display unit 32A changes the color attribute as the possibility of starting the engine increases, in other words, as the degree of tightness of the engine starting, which is the allowance of the battery 13, increases. The color attributes mentioned here mean hue, lightness, and saturation.
Hue refers to a hue, and is a property that can be distinguished by words such as red, yellow, green, blue, and purple. However, they are not independent of each other, and they are continuously connected to each other to form a hue.
Lightness refers to the degree of brightness of a color. Physically, the larger the amount of light reflected by a certain surface, the higher the brightness, and the smaller the amount, the lower the brightness. For example, white and yellow have high light reflectance and thus high lightness, while black and blue have low light reflectance and thus low lightness.
Saturation refers to a difference in properties such as “vividness” or “strength”. For example, even with reddish colors, the red Hinomaru is bright red, while the color of bricks is dull red.
For example, the first display unit 32A has different reference numerals 32A-1, 32A-2, and 32A-3 in FIGS. 2A, 2B, and 2C, and thus the first display unit 32A increases with increasing engine starting tightness. The hue of 32A is intermittently (stepwise) or continuously changed from a blue color or a green color to a red color, or displayed, or the lightness of the first display unit 32A is intermittently changed from a light color to a dark color. It is displayed by changing (stepwise) or continuously.
In this way, by changing the color attribute of the first display unit 32A, the driver can accurately grasp in advance the degree of urgency of starting the internal combustion engine, and the usability is improved.

Note that the engine start tightness is related to at least one of a plurality of conditions for starting the engine 12, and there is no margin until the condition is satisfied, the possibility of starting the engine 12 increases, and the engine 12 can start. ECU20 based on the SOC of the battery 13, the vehicle speed detected by the vehicle speed sensor 14, the accelerator opening detected by the accelerator opening sensor 15, the motor rotation speed of the motor 11, the motor output of the motor 11, and the like. Is calculated by performing arithmetic processing.

Further, in the display device 30 according to the present embodiment, when the output in the first mode exceeds a predetermined value, for example, when the engine start tightness exceeds a limit value (a predetermined value lower than the limit value may be used). Alternatively, part or all of the first display section 32A may be displayed by blinking (not shown). By blinking part or all of the first display portion 32A in this manner, the driver can be more aware (recognized) that the engine 12 is likely to be started.

Furthermore, the first region 32-1 may include a region that shows the output of the motor 11 when the engine 12 is operated to travel, that is, in the second mode. At this time, the first display unit 32A indicates the value corresponding to the output related to the motor 11 in the first region 32-1 (between the positions from 9:00 to 12:00). Specifically, the first display unit 32A changes the length (length from the 9 o'clock position) of the band-shaped figure, that is, the display amount, according to the output related to the motor 11, and the length of the band-shaped figure. The value corresponding to the motor output is indicated by (the position of the end point (tip portion) with the 9 o'clock position as the starting point).

Here, the output related to the motor 11 is the output due to the operation of the motor 11, and the motor output includes the rotation speed of the motor 11, the power (power) due to the operation of the motor 11, and the battery output of the battery 13 (the motor 11). Output parameters such as (assist power of) can be used.
The first display unit 32A has different color attributes in the first mode and the second mode. For example, a cold color system is used in the first mode, a warm color system is used in the second mode, the density is low in the first mode, and the density is high in the second mode.
As a result, the driver can obtain appropriate information suitable for the driving mode.

The traveling output in the first mode and the output related to the motor 11 in the second mode may be configured to be selectable by the driver. For example, the display device 30 is provided with a selection switch (not shown), and by operating this selection switch, one of the output parameters described above is output as the traveling output in the first mode and the output related to the motor 11 in the second mode. It suffices to select one output parameter from Here, when the first display unit 32A is changed according to the same output parameter in the first mode and the second mode, simplification of control can be achieved.

Thus, the first region 32-1 indicates the output of the motor 11 or the output of the battery 13 in the second mode, and the first display unit 32A displays the output of the motor 11 or the output of the battery 13 in the second mode. When it is assumed that the output changes depending on the output, the driver can obtain information on the assist output of the motor 11 as appropriate information according to the traveling state of the hybrid vehicle 10. And the surplus output of the battery 13 can be confirmed.

The third area 32-2 is an area for displaying the state of charge of the battery 13, and is arranged at a position of approximately 230° to 270° on the left side of the instrument panel 31. The third area 32-2 includes a level bar (not shown) that indicates the charge state of the battery 13.
The first area 32-1 and the third area 32-2 configure a digital meter 32 including a liquid crystal panel or the like. A section line L1 is arranged as a boundary at a position of about 270° on the left side of the instrument panel 31, which is between the first region 32-1 and the third region 32-2.

The second region 33 is an analog meter that indicates the traveling output in the second mode when the engine 12 is operated, that is, the analog region is provided on the instrument plate 31 so as to be provided side by side with the first region 32-1. The outer peripheral portion is arranged in a fan shape or an arc shape between the positions of 0° and about 130°. The 2nd field 33 has the 2nd indicator 33A which changes according to the run output in the 2nd mode.

The second display portion 33A is a pointer that indicates a value corresponding to the engine output in the second region 33 (between the position of 0° and about 130°). Specifically, the second display unit 33A displays the indication direction (the rotation angle from the direction of 0 o'clock (0°) with the approximate center of the instrument panel 31 as a reference point) according to the traveling output in the second mode. A value corresponding to the traveling output in the second mode is changed and indicated by the pointer according to the indicated direction (direction with the approximate center of the instrument panel 31 as a base point).

As described above, by using the second display portion 33A as a pointer, when the vehicle starts traveling in the second mode, the dynamic movement of the pointer causes the driver to more clearly understand the traveling in the second mode. Can be notified. Of course, the second area 33 may be a digital meter including a liquid crystal panel or the like.

As the traveling output in the second mode, for example, output parameters such as the rotation speed of the engine 12 and the power (power) by the operation of the engine 12 can be used.

The travel output in the above-described second mode may be selectable by the driver. For example, by providing a selection switch (not shown) on the display device 30 and operating the selection switch, one output parameter may be selected from the above-mentioned output parameters as the traveling output in the second mode. Good.
On the instrument panel 31, the display area including the first area 32-1, the second area 33, and the third area 32-2 is circular, and the first area 32-1 and the second area 33 are the display areas. It is provided in a fan-shaped or arc-shaped manner with the uppermost position as a boundary.

Further, the digital meter 32 and the second area 33, which is an analog meter, are provided bilaterally in the outer peripheral portion on the instrument panel 31, with the 12 o'clock position (the uppermost position T) of the instrument panel 31 as a boundary.

The operation of the display device according to the first embodiment of the present invention will be described with reference to FIGS. 1 and 2A to 2C.
When the driver starts the hybrid vehicle 10, the hybrid vehicle 10 starts traveling in the first mode, and the ECU 20 outputs the traveling output in the first mode to the digital meter 32 using the predetermined parameter (for example, the motor rotation speed). It is displayed in one area 32-1 (see FIGS. 1 and 2A).

At this time, the engine 12 is not started, the traveling output in the second mode (for example, engine speed) is “0”, and the second display unit 33A does not shake and the scale is “0” (instrument plate 31). 12 o'clock position).

Then, the first display portion 32A of the digital meter 32 changes its length (transitions within the range of the first region 32-1) according to the traveling output (for example, the motor rotation speed) in the first mode. ), the color attributes change depending on the degree of tightness of the engine start.

For example, when the traveling output in the first mode is increased by depressing the accelerator pedal or the like, the degree of tightness of the engine start is also increased. Therefore, the length (display amount) of the first display unit 32A in the digital meter 32 is As it changes (becomes longer), its hue or lightness also changes. Even when the running output in the first mode is not increased or decreased, the SOC of the battery 13 is decreased to increase the engine start tightness. Therefore, the first display portion 32A of the digital meter 32 is , Its hue or lightness is changed without changing its length (see FIGS. 1, 2A and 2B).

Then, when the engine start tightness approaches the limit value (maximum value), the first display portion 32A of the digital meter 32 further changes its hue or lightness, and when the engine start tightness reaches the limit value, The first display portion 32A blinks, the engine 12 starts, and the hybrid vehicle 10 shifts from traveling in the first mode to traveling in the second mode (see FIGS. 1 and 2C). At this time, the ECU 20 displays the traveling output in the second mode in the second region 33 with a predetermined parameter (for example, engine speed) (indicated by the second display section 33A).

At this time, the first display unit 32A is switched so that the traveling output in the second mode is displayed and the hue or brightness is different from that in the first mode.

Then, from the time the engine 12 starts to the time it stops, the second display portion 33A in the second area 33 is in full range (second display portion 33A) in the second area 33 according to the traveling output in the second mode. Of the digital meter 32, and the first display unit 32A of the digital meter 32 moves within the entire range of the first region 32-1 according to the traveling output (for example, battery output) in the first mode. ..

As described above, according to the display device 30, the running output in the first mode is displayed on the first display section 32A in the first area 32-1 of the digital meter 32, and the engine 12 may start. By changing the color attribute of the first display unit 32A according to (engine starting tightness), it is possible to clearly show to the driver that the hybrid vehicle 10 can travel in the first mode. Therefore, the driver can continue traveling in the first mode without anxiety.

In addition, the driver can operate the hybrid vehicle 10 based on the color or shade of the first display portion 32A in the first area 32-1. By operating the opening degree or the like, the first display unit 32A can be operated so as to return from the hue or lightness with which the engine 12 may start to the hue or lightness with which the engine 12 may not start.

Then, when the engine 12 is started, the first display unit 32A is switched so as to be different from the first mode in terms of color, and the traveling output in the second mode is displayed in the second region 33 on the second display unit 33A. By doing so, the driver can be made aware that the engine 12 is operating.

With the display device 30 having such a configuration, the traveling state of the hybrid vehicle 10 and the operating states of the motor 11 and the engine 12 can be easily understood, the driver can correctly understand the traveling state, and the intended driving can be performed. It will be easier.

The display device according to the present invention is not limited to the one that integrally changes and displays the hue or the brightness of the entire first display unit 32A like the display device 30 according to the present embodiment, and at least a part of the hue Alternatively, the brightness may be changed and displayed, or only the digital meter may be provided.

For example, as in the modified example shown in FIGS. 3A to 3C, the color or shade of the first display portion 132A is displayed while being intermittently (stepwise) or continuously changed in the longitudinal direction of the first display portion 132A. It may be the display device 130.

Specifically, when the running output and the engine start tightness in the first mode are low, the first display unit 132A displays two types of first display units 132A− that differ in hue or brightness. 1, 132A-2 (the degree of change is two steps) (see FIG. 3A). Next, when the running output and the engine starting tightness in the first mode are medium, the first display unit 132A displays three types of first display units 132A-1 and 132A having different colors or shades. -2, 132A-3 (the degree of change is three levels) (see FIG. 3B). Then, when the traveling output and the engine starting tightness in the first mode become high and reach the limit value, the first display portion 132A displays four types of first display portions having different hues or lightnesses. After being configured with 132A-1, 132A-2, 132A-3, and 132A-4 (the degree of change is four levels), the second display unit 33A will shake (see FIG. 3C).

Here, for example, when the SOC of the battery is low as in the modified example shown in FIGS. 4A to 4C, the battery output also decreases, so the length (maximum length) of the first display portion 232A corresponds to the output decrease. The display device 230 may be configured such that the hue or the brightness of the first display portion 232A is intermittently (stepwise) or continuously changed and displayed in the longitudinal direction of the first display portion 232A.

Specifically, when the traveling output and the engine starting tightness in the first mode are low, the first display portion 232A displays two types of first display portions 232A− that have different hues or lightnesses. 1, 232A-2 (the degree of change is two levels) (see FIG. 4A). Next, when the traveling output and the engine start tightness in the first mode are medium, the first display portion 232A displays three types of first display portions 232A-1 and 232A having different hues or lightnesses. 2, 232A-3 (the degree of change is three levels) (see FIG. 4B). Then, when the traveling output and the engine starting tightness in the first mode become high and reach the limit value, the first display portion 232A displays the four kinds of first display portions having different hues or lightnesses. After being configured with 232A-1, 232A-2, 232A-3, and 232A-4 (the degree of change is four steps), the second display unit 33A is shaken (see FIG. 4C).

In addition, for example, as in the modified example shown in FIGS. 5A to 5C, a part (tip portion) of the first display portion 332A has a hue or lightness corresponding to the limit value of the engine start tightness, and the other portion has the engine start. It may be the display device 330 that changes the hue or brightness according to the degree of tightness and displays.

Specifically, when the running output and the engine starting tightness in the first mode are low, the first display portion 332A has a hue or lightness corresponding to the limit value of the engine starting tightness. The display unit 332A-4 and the first display unit 332A-1 having a hue or a lightness corresponding to a low engine start tightness (see FIG. 5A). Next, when the traveling output and the engine starting tightness in the first mode are medium, the first display portion 332A is in accordance with the first display portion 332A-4 and the medium engine tightness. And a first display portion 332A-2 having different hue or brightness (see FIG. 5B). Then, when the running output and the degree of engine start tightness in the first mode reach an upper limit and reach the limit value, the first display portion 332A causes the first display portion 332A-4 and the engine start tightness of the altitude described above. After being configured with the first display portion 332A-3 having the hue or the lightness according to the degree, the second display portion 33A is shaken (see FIG. 5C).

Further, for example, as in the modified examples shown in FIGS. 6A to 6C, the display device 430 may be provided in which only the digital meter 432 having the first display portion 432A is provided on the instrument panel 431. In this case, the second region indicating the traveling output in the second mode is omitted.

Specifically, when the traveling output and the engine starting tightness in the first mode are low, the first display portion 432A has the first hue or the lightness corresponding to the limit value of the engine starting tightness. The display unit 432A-4 and the first display unit 432A-1 having a hue or lightness corresponding to a low engine starting tightness (see FIG. 6A), the running output in the first mode and the engine starting tightness.
