Embodiments of a display device according to the present invention will be described in detail below with reference to the accompanying drawings. Of course, the present invention is not limited to the following examples, and it goes without saying that various changes can be made without departing from the spirit of the present invention.

[Example 1]
The configuration of a display device according to Example 1 of the present invention will be described with reference to FIG. 1 and FIGS. 2A to 2C.

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

The driving mode of the hybrid vehicle 10 is a first mode (where the engine 12 is stopped and priority is given to driving using the motor 11 (driving the drive wheels) (giving priority to driving using the motor 11 over driving using the engine 12). The vehicle has two modes: an electric motor output mode) and a second mode (internal combustion engine output mode) in which the engine 12 is operated and, for example, the motor 11 and the engine 12 are used to travel (drive the drive wheels).

Further, the hybrid vehicle 10 includes an ECU (Electronics Control Unit) 20 that is a control section. The ECU 20 has a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), an input/output circuit, etc., is electrically connected to the motor 11 and the engine 12, and supplies power to the motor 11. It is also electrically connected to a driving battery 13 that supplies the vehicle speed, a vehicle speed sensor 14 that detects the vehicle speed, and an accelerator opening sensor 15 that detects the accelerator opening.

Therefore, signal values from the motor 11 (motor rotation speed, etc.) and signal values from the engine 12 (on/off, engine rotation speed, etc.) are input to the ECU 20, and also signal values from the battery 13 (SOC (State of Charge, battery output, etc.) and signal values of the vehicle speed sensor 14 and accelerator opening sensor 15 are also input.

The hybrid vehicle 10 further includes a display device 30A that displays one of a plurality of outputs (driving output) related to the traveling of the hybrid vehicle 10, and the display device 30A is electrically connected to the ECU 20. has been done. The driving output of the hybrid vehicle 10 is determined by arithmetic processing performed in the ECU 20 based on the above-mentioned signal values, and the calculated value (driving output) thus processed is input to the display device 30A.

As shown in FIGS. 2A to 2C, the display device 30A has a circular instrument panel 35 in which a first area 31A (including a third area 33A), a second area 32A, and a fourth area 34A are arranged. are doing. In the following description, the direction on the instrument panel 35 will be expressed as the time of a clock with the topmost position T of the instrument panel 35 at 0 o'clock (=12 o'clock), or with the topmost position T of the instrument panel 35 as 0 o'clock (=12 o'clock). Either or both of the angles at the position of 360° (=360°) are used.

The first area 31A is an area that indicates the driving output (first output) when the engine 12 is stopped and the motor 11 is used to drive, that is, in the first mode. They are arranged in a fan or arc shape between positions of about 270° to 360° (9 o'clock to 12 o'clock). In the first area 31A, a first display section 36 that changes depending on the driving output (first output) in the first mode is displayed.

The first display section 36 is a band-shaped image indicating a value corresponding to the running output (first output) in the first mode in the first area 31A (between the 9 o'clock and 12 o'clock positions). Specifically, the first display section 36 changes the length of the strip shape (length from the 9 o'clock position) according to the running output (first output) in the first mode, and displays the strip shape. The length of the figure (the position of the end point (tip) starting from the 9 o'clock position) indicates the value corresponding to the running output (first output) in the first mode.

In this way, by making the first display section 36 a band-shaped image, the driver can be informed of the running state of the vehicle and whether the engine 12 is started or not when driving in the first mode without starting the engine 12. The stop state can be notified more clearly, and visibility is improved. Note that the first display section 36 is not limited to an image of a band-shaped figure, and may be, for example, a pointer similar to a second display section 37 described later, as shown in FIG. 3.

FIG. 3 is an explanatory diagram showing another example of the embodiment of the display device for a hybrid vehicle. The display devices 30A shown in FIGS. 2A to 2C and the display device 30A shown in FIG. 3 have the same components other than the first display section 36 in FIG. 3. Identical components other than the first display section 36 are given the same reference numerals and their explanations will be omitted.
The first display section 36 in FIG. 3 is a pointer that indicates a value corresponding to the traveling output (first output) in the first mode in the first area 31A (between 9 o'clock and 12 o'clock positions). Specifically, the first display section 36 changes its indicated direction (rotation angle from the 9 o'clock position) according to the driving output (first output) in the first mode, and the indicated direction (rotation angle from the 9 o'clock position) changes. (clockwise rotation angle starting from the hour position) indicates a value corresponding to the running output in the first mode (first output).
In this way, since both the first display section 36 and the second display section 37 (to be described later) are shown as pointers, that is, the first display section 36 and the second display section 37 are shown in the same display format, it is possible to In this case, when both the first display section 36 and the second display section 37 move, displays of the same type move in conjunction with each other, so visibility is improved and the design is improved.

As the running output (first output) in the first mode, for example, an output parameter such as the battery output of the battery 13 can be used.

Further, a third region 33A is provided in the first region 31A. The third region 33A is provided in the first region (31A) at a location close to the second region (32A). A dividing line (boundary) L1 indicating the starting point of the third area 33A is provided in the first area 31A. The dividing line L1 is a display indicating a limit position (a value corresponding to the traveling output) in which the engine 12 is stopped and traveling using the motor 11 is prioritized in the first mode.

Here, a state where the engine 12 is stopped and priority is given to traveling using the motor 11 is a state where all of the plurality of conditions for starting the engine 12 are not satisfied. On the other hand, a state in which there is a possibility (high probability) that the engine 12 will start is a state in which at least one of the plurality of conditions for starting the engine 12 is satisfied. A dividing line L1 indicates a boundary between these states, that is, a limit region in which the engine 12 is stopped and travel using the motor 11 is prioritized. Note that, depending on conditions, the engine 12 may start at a counterclockwise position (within the first region 31A) with respect to the dividing line L1.

In other words, the third region 33A included in the first region 31A is activated when at least one of the plurality of conditions for starting the engine 12 is satisfied and the possibility that the engine 12 will start is increased, that is, from the first mode. This is an engine start tight region that indicates the driving output when there is a possibility (high possibility) of shifting to the second mode. Further, the third region 33A is arranged in a fan shape or an arc shape between the position of the dividing line L1 and the position of 0° (0 o'clock) (a place close to the second region 32A) within the first region 31A. There is.

Therefore, in the first mode, if there is no possibility (low possibility) that the engine 12 will start, the first display section 36 will be displayed within the range of the first region 31A excluding the third region 33A. On the other hand, when there is a possibility (high possibility) that the engine 12 will start, that is, immediately before the engine 12 starts, the first display section 36 displays the third area within the first area 31A. It remains within the range of 33A.

By providing such a third area 33A within the first area 31A, it is possible to indicate on the first display section 36 that there is a possibility that the engine 12 will start. You can know that it is easy. Therefore, the driver can easily understand the running state of the hybrid vehicle 10 and the operating state of the motor 11, correctly grasp the running output, and easily realize the intended driving.

Further, the first region 31A may include a region indicating the output of the motor 11 (motor output) when the engine 12 is operated and the vehicle is traveling, that is, in the second mode. At this time, the dividing line L1 is hidden, and the first display section 36 indicates the value corresponding to the motor output (second output) in the first area 31A (between the 9 o'clock and 12 o'clock positions). It turns out. Specifically, in the first display section 36, the length of the band-like figure (length from the 9 o'clock position) changes according to the motor output (second output), and the length of the band-like figure (length from the 9 o'clock position) changes. The value corresponding to the motor output (second output) is indicated by the position of the end point (tip end) starting from the 9 o'clock position.

Here, the motor output (second output) is the output due to the operation of the motor 11, and the motor output (second output) includes the rotation speed of the motor 11, the power (power) due to the operation of the motor 11, the battery Output parameters such as No. 13 battery output (assist power of motor 11) can be used.

In this way, by hiding the marking line L1 in the second mode, the change in the display in the first area 31A becomes noticeable when the first mode shifts to the second mode, and the driver can easily control the hybrid vehicle 10. It is possible to more easily determine the driving state, especially whether the vehicle is traveling in the second mode.

Note that the driving output in the first mode (first output) and the motor output in the second mode (second output) described above may be configured to be selectable by the driver. For example, a selection switch (not shown) is provided on the display device 30A, and by operating this selection switch, the traveling output in the first mode (first output) and the motor output in the second mode (second output) can be set. , one output parameter may be selected from among the output parameters described above. Here, if the first display section 36 is configured to change according to the same output parameter in the first mode and the second mode, control can be simplified.

Further, the first area 31A indicates the output of the motor 11 or the output of the battery 13 in the second mode, and the first display section 36 indicates the output of the motor 11 or the output of the battery 13 in the second mode. If it changes, the driver can obtain information on the assist output of the motor 11 as appropriate information according to the driving state of the hybrid vehicle 10. More specifically, the assist output of the motor 11 and the battery 13 can be changed. You can check the surplus output.

The second region 32A is a region indicating the traveling output (third output) when the engine 12 is operated and traveling, that is, in the second mode. They are arranged in a fan or arc shape between the ° positions. A second display section 37 is displayed in the second area 32A, which is provided separately from the first display section 36 and changes depending on the running output (third output) in the second mode.

The second display section 37 is a pointer that indicates a value corresponding to the engine output within the second region 32A (between positions from 0° to approximately 135°). Specifically, the second display section 37 changes the indicated direction (from the direction of 0 o'clock (0°) with the approximate center of the instrument panel 35 as the base point) according to the driving output (third output) in the second mode. (rotation angle) changes, and the indicated direction (direction based on approximately the center of the instrument panel 35) indicates a value corresponding to the running output (third output) in the second mode.

In this way, by using the second display section 37 as a pointer, when driving in the second mode starts, the pointer moves dynamically, making it clearer to the driver that driving in the second mode is in progress. can be notified.

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

Note that the driving output (third output) in the second mode described above may be configured to be selectable by the driver. For example, a selection switch (not shown) is provided on the display device 30A, and by operating this selection switch, one output parameter from the above-mentioned output parameters is selected as the running output (third output) in the second mode. You should choose.

Here, when the second display section 37 displays the number of revolutions of the engine 11, the driver can display such (driving It is possible to easily understand the operation of the engine 11 (for purposes other than the above).

The fourth region 34A is a region indicating the charging output of the battery 13 by regenerated energy, and is arranged in a fan shape or an arc shape between approximately 225° and 270° on the outer peripheral portion of the instrument panel 35. A regenerative energy display section (not shown) that changes depending on the power generation output of the motor 11 using regenerative energy is displayed in the fourth area 34A.

The regenerative energy display section (not shown) is a band-shaped image indicating a value corresponding to the power generation output of the motor 11 due to regenerative energy in the fourth region 34A (between approximately 225° and 270° positions). Specifically, in the regenerative energy display section (not shown), the length of the band-shaped figure (length from the 270° position) changes depending on the power generation output of the motor 11 due to the regenerative energy, and the length of the band-shaped figure The length (the position of the end point (tip) with the 270° position as the starting point) indicates a value corresponding to the power generation output of the motor 11 due to regenerative energy.

In the instrument panel 35 described above, the first area 31A (including the third area 33A) and the fourth area 34A do not have scale numbers written on them, and the second area 32A has scale numbers written on them. . Of course, scale numbers may be written in the first area 31A (including the third area 33A) and the fourth area 34A, and it is not necessary to write scale numbers in the second area 32A.

Further, in the above-mentioned instrument panel 35, the first display section 36 and the regenerative energy display section (not shown) are images of band-shaped figures, and the second display section 37 is a pointer of an analog meter. Of course, for example, as shown in FIG. 3, the first display section 36 may be used as a guide, the regenerative energy display section (not shown) may be used as a guide, and the second display section 37 may be an image of a band-shaped figure. At this time, it is preferable that the first display section 36 and the second display section 37 are shown in different display formats. Note that the different display formats may be any display format that allows the driver to clearly distinguish between the two display sections, and is not limited to the above-mentioned band-shaped image and pointer.

Further, the first region 31A (including the third region 33A), the second region 32A, and the fourth region 34A described above are each arranged in a fan shape or an arc shape in a predetermined range, and are arranged in a fan shape or an arc shape in a similar fan shape or They are arranged independently in a predetermined range in a circular arc shape, and are arranged in a fan shape or a circular arc shape as a whole. Note that the first region 31A (including the third region 33A) and the second region 32A are provided in a continuous arc shape with the boundary at the 12 o'clock position.

In this way, the display area consisting of the first area 31A and the second area 32A is circular, and the first area 31A and the second area 32A are formed into a fan-shaped or By arranging them in a continuous arc, the driver can easily grasp the information displayed on the display device 30A (the operating state of the hybrid vehicle 10) intuitively.

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

When the driver starts the hybrid vehicle 10, the hybrid vehicle 10 starts running in the first mode.

At this time, on the instrument panel 35 of the display device 30A, the first display section 36 and the dividing line L1 are displayed in the first area 31A, and the first display section 36 shows the driving output in the first mode (the first output), the output changes within the range of the first region 31A (see FIGS. 2A and 2B). Note that in the first mode, the engine 12 is not started, and the second display section 37 does not swing within the second area 32A (points at "0" on the scale).

Here, the first display section 36 and the dividing line L1 indicate a predetermined output parameter or an arbitrary output parameter selected by a selection switch (not shown) (for example, engine starting displayed in terms of severity).

Therefore, on the instrument panel 35 of the display device 30A, the driver can confirm that the hybrid vehicle 10 is in the first mode because the second display section 37 is not oscillating within the second area 32A (pointing at "0" on the scale). It is possible to easily recognize that the hybrid vehicle 10 is traveling in the same state (the driving state of the hybrid vehicle 10).

The driver also knows that the hybrid vehicle 10 is running in the first mode (hybrid vehicle 10 (driving condition) can be easily recognized.

Then, while the running output (first output) in the first mode is a running output that does not exceed the dividing line L1, that is, a running output that has no possibility of starting the engine 12, the first display unit 36 Depending on the traveling output (first output) in the first mode, the vehicle changes within the range of the first region 31A excluding the third region 33A (see FIG. 2A).

Therefore, the driver can check the display of the first display part 36 and the dividing line L1 in the first area 31A (the first display part 36 is moving within the range of the area excluding the third area 33A in the first area 31A). Therefore, the driver can easily recognize that the vehicle can travel in the first mode, and can continue traveling in the first mode with peace of mind.

On the other hand, when the traveling output (first output) in the first mode exceeds the dividing line L1, that is, reaches a traveling output at which there is a possibility that the engine 12 will start, the first display will be displayed until the engine 12 starts. The portion 36 moves within the range of the third region 33A within the first region 31A depending on the driving output in the first mode (see FIG. 2B).

Therefore, the driver can operate the hybrid vehicle 10 while grasping the positional relationship between the first display section 36 and the marking line L1 (the third area 33A within the first area 31A). If you do not want to start the engine 12, operate the accelerator opening or the like so that the first display section 36 returns to the range of the first region 31A excluding the third region 33A. I can do it.

Then, when the running output (first output) in the first mode exceeds, for example, the maximum output of the battery 13, the engine 12 is started and the hybrid vehicle 10 starts running in the second mode.

At this time, on the instrument panel 35 of the display device 30A, the second display section 37 swings (displays/moves) from the scale "0" within the second area 32A, and the second display section 37 is in the second mode. The vehicle changes within the second region 32A according to the running output (third output) (see FIG. 2C).

Here, the second display section 37 displays a predetermined output parameter or an arbitrary output parameter (for example, the rotation speed of the engine 12) selected by a selection switch (not shown) as the running output (third output) in the second mode. In addition, the first display section 36 displays a predetermined output parameter or an arbitrary output parameter selected by a selection switch (not shown) (for example, of the motor 11) as the motor output (second output) in the second mode. (rpm). Note that the dividing line L1 is not displayed.

Therefore, on the instrument panel 35 of the display device 30A, the driver can see that the hybrid vehicle 10 changes from the first mode to the second mode by the dynamic movement of the second display section 37 when driving in the second mode starts. It is easy to recognize that the transition has been made, and the second display section 37 is oscillating within the second area 32A (pointing at a value other than "0" on the scale), indicating that the hybrid vehicle 10 is in the second mode. It is possible to easily recognize that the vehicle is running (driving state of the hybrid vehicle 10).
