The hybrid vehicle 10 may also include a generator 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), a second mode in which the engine 12 is operated and the vehicle runs using the motor 11 and the engine 12 (drives drive wheels), and an internal combustion engine output mode.

  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 battery 13 for driving to be supplied, the vehicle speed sensor 14 for detecting the vehicle speed, and the accelerator opening sensor 15 for detecting the accelerator opening are also electrically connected.

  Therefore, a signal value from the motor 11 (motor speed, etc.) and a signal value from the engine 12 (ON / OFF, engine speed, etc.) are input to the ECU 20, and a signal value (SOC) from the battery 13 is input. (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 30A that displays an output (travel output) related to the travel of the hybrid vehicle 10, and the display device 30A is electrically connected to the ECU 20. The traveling output of the hybrid vehicle 10 is obtained by performing an arithmetic process on the ECU 20 based on the above-mentioned signal value, and the arithmetic value (travel output) thus arithmetically processed is input to the display device 30A.

  As shown in FIGS. 2A to 2E, a display device 30A is a circular instrument in which a first output display area 32A, a second output display area 31A, and a regenerative energy display area 33A are arranged adjacent to each other in the circumferential direction. It has a plate 34. In the following description, as a representation of the azimuth on the instrument panel 34, the time of the clock when the uppermost position T of the instrument panel 34 is at 0 o'clock (= 12 o'clock) or the uppermost position T of the instrument panel 34 is 0. Either one or both of the angles defined as the position of ° (= 360 °) is used.

  The second output display area 31A is an area in which the running output in the first mode, that is, the output of the motor 11 or the battery 13 is displayed when the engine 12 is stopped and the vehicle travels using the motor 11, On the outer peripheral portion on the instrument panel 34, the fan-shaped or arc-shaped arrangement is provided between the positions of about 270 ° to 360 ° (9 to 12 o'clock).

Specifically, the electric motor output display unit 35 changes its gauge length (length from the 9 o'clock position) according to the traveling output in the first mode, and the gauge length (9 o'clock position) is changed. The position corresponding to the traveling output in the first mode is indicated by the end point (the position of the tip end portion) starting from.

  As the traveling output in the first mode, for example, output parameters such as the motor rotation speed of the motor 11, the power (power) by the operation of the motor 11, the battery output of the battery 13, the vehicle speed, and the accelerator opening degree can be used. ..

  Here, in the second output display area 31A, when a plurality of conditions for starting the engine 12 are satisfied and the possibility that the engine 12 is started is increased, that is, there is a possibility of shifting from the first mode to the second mode. It may have an engine start tight region (not shown) that indicates the running output when there is a certain amount. By providing such an engine start tight area in the second output display area 31A, it is possible to indicate on the electric motor output display section 35 that the engine 12 may start, so that the running state of the hybrid vehicle 10 and The operation state of the motor 11 becomes easy to understand, and the driver can easily understand the traveling output and easily realize the intended driving.

  Further, the second output display area 31A may include an area showing the battery output of the battery 13 in the second mode when the engine 12 is operated to travel. At this time, the electric motor output display unit 35 indicates the position corresponding to the battery output in the second output display area 31A (between the positions from 9:00 to 12:00).

  Specifically, the electric motor output display unit 35 changes its gauge length (length from the 9 o'clock position) according to the battery output, and the gauge length (starting from the 9 o'clock position is the end point). The position corresponding to the battery output is indicated by (the position of the tip).

  The traveling output in the first mode and the battery output in the second mode described above may be selectable by the driver. For example, the display device 30A is provided with a selection switch (not shown), and by operating this selection switch, the traveling output in the first mode and the battery output in the second mode are set to 1 from the output parameters described above, respectively. It suffices to select one output parameter.

Specifically, the internal combustion engine output display unit 36 changes its gauge length (the length from the 0 ° position) according to the engine output, and the gauge length (the 0 ° position is set as the starting point). The position corresponding to the engine output is indicated by the end point (the position of the tip).

  The engine output is an output due to the operation of the engine 12, and as the engine output, for example, output parameters such as the engine speed of the engine 12 and the power (power) due to the operation of the engine 12 can be used.

  Here, as shown in FIG. 2C, the internal combustion engine output display unit 36 is roughly configured by a drive output display unit 36-1 and a charge output display unit 36-2 which have different display forms. In the present embodiment, the drive output display section 36-1 and the charge output display section 36-2 have different color attributes so as to have different display forms. The "color attribute" here means hue, lightness, and saturation.

  In the internal combustion engine output display unit 36, the drive output display unit 36-1 displays the traveling output of the hybrid vehicle 10 due to the operation of the engine 12, that is, the output (drive output) of the engine output required for driving the hybrid vehicle 10. Accordingly, the gauge length changes. The gauge length of the drive output display unit 36-1 is the length from the position of 0 °. Alternatively, it is the length from the position of the end point (tip portion) of the charging output display portion 36-2.

  The charge output display unit 36-2 displays the charge output of the battery 13 due to the operation of the engine 12 in the internal combustion engine output display unit 36, that is, the output (charge output) used for charging the battery 13 of the engine output. Accordingly, the gauge length changes. The gauge length of the charging output display unit 36-2 is the length from the position of the end point (tip portion) of the drive output display unit 36-1 starting from the position of 0 ° or the length from the position of 0 °. That's it.

  That is, the internal combustion engine output display unit 36 indicates the position corresponding to the engine output which is the resultant force of the drive output and the charge output, and the hue or brightness of the drive output display unit 36-1 and the charge output display unit 36-2. By distinguishing (dividing), the display ratio indicates the output ratio of the drive output and the charging output.

  The engine output described above may be configured to be selectable by the driver. For example, a selection switch (not shown) may be provided on the display device 30A, and by operating this selection switch, one output parameter may be selected from the above-mentioned output parameters as the engine output.

  The regenerative energy display area 33A is a regenerative energy display area showing the charging output of the battery 13 by the regenerative energy, and is arranged in a fan shape or an arc shape between the positions of about 225 ° to 270 ° on the outer peripheral portion on the instrument panel 34. Has been done. The regenerative energy display area 33A is provided with a regenerative energy display portion 37 that changes according to the charging output of the battery 13 by the regenerative energy.

  The regenerative energy display portion 37 is a level bar of a digital meter that indicates a position in the regenerative energy display area 33A (between the positions of about 225 ° and 270 °) corresponding to the charging output of the battery 13 by the regenerative energy. Specifically, the regenerative energy display unit 37 changes its gauge length (the length from the position of 270 °) according to the charging output of the battery 13 by the regenerative energy, and the gauge length (of 270 °) is changed. The position corresponding to the charging output of the battery 13 by the regenerative energy is indicated by the end point (the position of the tip end) with the position as the starting point.

  In the above-described instrument panel 34, the second output display area 31A and the regenerative energy display area 33A are not marked with scale numbers, and the first output display area 32A is marked with scale numbers. Of course, the scale numbers may be written on the second output display area 31A and the regenerative energy display area 33A, and the scale numbers may not be written on the first output display area 32A.

  Further, the second output display area 31A, the first output display area 32A, and the regenerative energy display area 33A described above are arranged in a fan shape or an arc shape within a predetermined range, respectively, and have a similar fan shape or arc shape. They are independently arranged in a predetermined range, and are also arranged in a fan shape or an arc shape as a whole. The second output display area 31A and the first output display area 32A are provided in an arc shape with the 12:00 position as a boundary. Further, the second output display area 31A and the first output display area 32A are not limited to having the uppermost position at 12 o'clock as a boundary, and may have the boundary at 9 o'clock, for example. ..

  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 2E.

  When the driver starts the hybrid vehicle 10, the hybrid vehicle 10 starts traveling in the first mode (see FIG. 2A).

It changes within the range of the output display area 31A. In addition, in the first mode, the engine 12 is not started, and the internal combustion engine output display unit 36 is not displayed in the first output display area 32A.

  Here, when the second output display area 31A has the above-described engine start tight area (not shown), the motor output display section 35 displays the first mode when the engine 12 may start. It changes within the range of the engine start tight area in the second output display area 31A according to the traveling output.

  Therefore, on the instrument panel 34 of the display device 30A, the driver displays the electric motor output display section 35 in the second output display area 31A and does not display the internal combustion engine output display section 36 in the first output display area 32A. From this, it is possible to easily recognize that the hybrid vehicle 10 is traveling in the first mode (the traveling state of the hybrid vehicle 10).

  In addition, the driver displays the traveling output in the first mode (the traveling state of the hybrid vehicle 10 and the motor 11 from the display of the electric motor output display portion 35 (gauge length of the electric motor output display portion 35) in the second output display area 31A).

It changes within the range of 32A (see FIGS. 2B to 2E).

  Therefore, since the internal combustion engine output display section 36 is displayed in the first output display area 32A on the instrument panel 34 of the display device 30A, the driver is running the hybrid vehicle 10 in the second mode ( The running state of the hybrid vehicle 10) can be easily recognized.

  Further, the driver can correctly grasp the engine output (operating state of the engine 12) from the display of the internal combustion engine output display section 36 (gauge length of the internal combustion engine output display section 36) in the first output display area 32A. it can.

  In the second mode, when the hybrid vehicle 10 operates only the engine 12 and the engine output is used only for traveling (drive output) of the hybrid vehicle 10, the electric motor output display unit 35 displays the second output. The internal combustion engine output display section 36 is not displayed in the display area 31A, and is displayed only in the drive output display section 36-1 in the first output display area 32A (see FIG. 2B).

  Therefore, the driver does not display the motor output display section 35 in the second output display area 31A and displays the internal combustion engine output display section 36 in the first output display area 32A on the instrument panel 34 of the display device 30A. Therefore, it is possible to easily recognize that the hybrid vehicle 10 is traveling by operating only the engine 12 in the second mode (the traveling state of the hybrid vehicle 10).

  Further, the driver displays the internal combustion engine output display section 36 in the first output display area 32A (only the drive output display section 36-1 is displayed, and the drive output display section 36-1 and the charge output display section 36-2 are displayed. The engine output is used only for traveling (driving output) of the hybrid vehicle 10, and the output ratio of the driving output and the charging output of the engine output is It is possible to easily recognize that it is "10: 0" (the operating state of the engine 12).

  Furthermore, from the display of the internal combustion engine output display unit 36 (gauge length of the drive output display unit 36-1) in the first output display area 32A, the driver outputs the drive output (the running state of the hybrid vehicle 10 and the operation of the engine 12). It is possible to grasp the condition correctly.

  Next, in the second mode, when the hybrid vehicle 10 operates only the engine 12 and the engine output is used for traveling of the hybrid vehicle 10 (driving output) and charging of the battery 13 (charging output), The electric motor output display section 35 is not displayed in the second output display area 31A, and the internal combustion engine output display section 36 is the drive output display section 36-1 and the charge output display section 36-2 in the first output display area 32A. Is displayed (see FIG. 2C).

  Therefore, the driver does not display the motor output display section 35 in the second output display area 31A and displays the internal combustion engine output display section 36 in the first output display area 32A on the instrument panel 34 of the display device 30A. Therefore, it is possible to easily recognize that the hybrid vehicle 10 is traveling by operating only the engine 12 in the second mode (the traveling state of the hybrid vehicle 10).

  In addition, from the display of the internal combustion engine output display unit 36 (the display of the drive output display unit 36-1 and the charge output display unit 36-2) in the first output display area 32A, the driver indicates that the engine output is the hybrid output. It is used for running the vehicle 10 (driving output) and charging the battery 13 (charging output), and easily recognizes that the engine output is assigned to the driving output and the charging output (operating state of the engine 12). can do.

  As described above, when the engine output is used for traveling (driving output) of the hybrid vehicle 10 and charging (charging output) of the battery 13, for example, when the engine output has a surplus, traveling required by the driver Examples include when the output is too low to be efficient, or in charge mode or emergency power generation.

  Next, in the second mode, when the hybrid vehicle 10 operates only the engine 12 and the engine output is used only for charging the battery 13, the electric motor output display unit 35 displays the second output display area 31A. The internal combustion engine output display section 36 is displayed only on the charge output display section 36-2 in the first output display area 32A (see FIG. 2D).

  Therefore, the driver does not display the motor output display section 35 in the second output display area 31A and displays the internal combustion engine output display section 36 in the first output display area 32A on the instrument panel 34 of the display device 30A. Therefore, it is possible to easily recognize that the hybrid vehicle 10 is traveling by operating only the engine 12 in the second mode (the traveling state of the hybrid vehicle 10).

  As described above, when the engine output is used only for charging the battery 13, for example, the hybrid vehicle 10 is decelerating. When the hybrid vehicle 10 is decelerating, the regenerative energy display portion 37 is displayed in the regenerative energy display area 33A, and the driver can recognize that the battery 13 is charged by the regenerative energy. ..

  Next, in the second mode, when the hybrid vehicle 10 operates the motor 11 and the engine 12 and these outputs (motor output and engine output) are used only for traveling of the hybrid vehicle 10, the motor output The display section 35 is displayed in the second output display area 31A, and the internal combustion engine output display section 36 is displayed only in the drive output display section 36-1 in the first output display area 32A (see FIG. 2E).

Therefore, it is possible to easily recognize that the hybrid vehicle 10 is traveling by operating the motor 11 and the engine 12 in the second mode (the traveling state of the hybrid vehicle 10).
