  The hybrid vehicle 20 of the embodiment configured in this manner calculates a required torque to be output to the vehicle based on the accelerator opening Acc and the vehicle speed V corresponding to the depression amount of the accelerator pedal by the driver, and corresponds to this required torque. The engine 22 and the motors MG1, MG2, and MG3 are controlled to run with the required power. As the operation control of the engine 22 and the motors MG1, MG2, and MG3, the operation of the engine 22 is controlled so that the power corresponding to the required power is output from the engine 22, and all the power output from the engine 22 is transmitted to the planetary gear 30 and the motor. Torque conversion operation mode in which the motor MG1, the motor MG2, and the motor MG3 are driven and controlled so as to be output by being torque-converted by one or both of the motor MG1, the motor MG2, and the motor MG3. Operation of the engine 22 is controlled so that power corresponding to the sum of necessary electric power is output from the engine 22, and all or part of the power output from the engine 22 with charge / discharge of the battery 50 is transmitted to the planetary gear 30.

Or a motor operation mode in which operation control is performed so that power corresponding to the required power is output from both. Note that the torque conversion operation mode and the charge / discharge operation mode are modes in which the engine 22 and the motors MG1, MG2, MG3 are controlled so as to travel with the required power accompanying the operation of the engine 22, so It can be considered as an engine operation mode.

  In the hybrid vehicle 20 of the embodiment, the electronic control unit 70 causes the display unit 90 to display the engine 22, the motors MG1, MG2, the front wheels 63a, 63b, the battery 50, the motor MG3, the rear wheels 66a, 66b, and the outlet 52. A figure (hereinafter referred to as an element figure) of elements (hereinafter referred to as a motor MG) for elements (motors MG1 and MG2 are combined together) and an arrow indicating the flow of energy between the elements as necessary. Is displayed. FIG. 2 is an explanatory diagram illustrating an example of display contents of the display unit 90. In FIG. 2, for convenience of the following description, the same reference numerals as the corresponding elements are assigned to the respective element figures. In the embodiment, when traveling in the engine operation mode, the arrow A between the engine 22 and the motor MG, the arrow B between the engine 22 and the front wheels 63a and 63b, the arrow C between the motor MG and the front wheels 63a and 63b, and the motor MG- An arrow D between the batteries 50, an arrow E between the motor MG3 and the battery 50, and an arrow F between the motors MG3 and the rear wheels 66a and 66b are displayed on the display unit 90 as directions of arrows corresponding to the direction of energy flow, When traveling in the motor operation mode, an arrow C between the motor MG and the front wheels 63a and 63b, an arrow D between the motor MG and the battery 50, an arrow E between the motor MG3 and the battery 50, and between the motor MG3 and the rear wheels 66a and 66b. The arrow F is displayed on the display unit 90 as the direction of the arrow corresponding to the direction of energy flow. Thereby, the driver can be notified of the energy flow according to the operation mode. In the embodiment, when an external device that is not a component of the vehicle is connected to the outlet 52 and power is supplied from the battery 50 to the external device, an arrow G between the battery 50 and the outlet 52 is displayed on the display unit 90. To do. Thereby, for example, when the electric bicycle is loaded into the hybrid vehicle 20 and the electric bicycle is charged or when the electric product is used in the vehicle, the electric power from the battery 50 is supplied to the external device such as the electric bicycle or the electric product. The driver can be notified of the supply. As a result, the remaining capacity of the battery 50 is reduced due to the power supply from the battery 50 to the external device while the engine 22 is stopped, such as when the motor 22 is running or stopped, and the battery 50 is charged. Even when the engine 22 is started, the start can be prevented from being unexpectedly started by the driver. Further, in the embodiment, for the arrows A to G described above, the display color is changed according to the magnitude of flowing energy (for example, the order is changed in the order of red, orange, and yellow as the energy increases). It was. Specifically, this change in display color is a color in which a plurality of types of light emitting diodes having different emission colors are arranged at the display position of the arrow, and the combination of light emitting diodes to be lit when displaying the arrow is displayed. It was supposed to be done by changing according to. Thereby, the magnitude | size of the flowing energy can be alert | reported easily to a driver | operator.

  Furthermore, in the hybrid vehicle 20 of the embodiment, when an external device is connected to the outlet 52 and power is supplied from the battery 50 to the external device, the power supply may be performed with relatively large power. For example, the stop allowable lower limit remaining capacity as the lower limit of the remaining capacity range of the battery 50 that allows the engine 22 to stop operating is set to a value S1 when an external device is not connected to the outlet 52 (for example, It is assumed that the value S2 (for example, 60%, 65%, etc.) is larger than 40%, 45%, etc. Thereby, when electric power is supplied from the battery 50 to the external device with relatively large electric power, overdischarge of the battery 50 can be suppressed.

  According to the hybrid vehicle 20 of the embodiment described above, when an external device is connected to the outlet 52 connected to the battery 50 and power is supplied from the battery 50 to the external device, the battery 50 and the outlet 52 are connected. Since the arrow G is displayed, the driver can be notified of the situation. As a result, even when the engine 22 is started to charge the battery 50 while the remaining capacity of the battery 50 is reduced due to this power supply while the engine 22 is stopped, this start is expected by the driver. It is possible to suppress starting.

  In the hybrid vehicle 20 of the embodiment, the arrows A to G described above change the display color according to the magnitude of flowing energy, but the same color is displayed regardless of the magnitude of flowing energy. Also good.

  In the hybrid vehicle 20 of the embodiment, the element graphic for the motor MG2 in which the motors MG1 and MG2 are combined into one is displayed on the display unit 90. However, the element graphic corresponding to each of the motors MG1 and MG2 is displayed on the display unit. 90 may be displayed.

  In the hybrid vehicle 20 of the embodiment, when the power is supplied from the battery 50 to the external device, the stop allowable lower limit remaining capacity is larger than when the power is not supplied from the battery 50 to the external device. However, the same value may be set as the stop allowable lower limit remaining capacity regardless of whether power is supplied from the battery 50 to the external device.

  The hybrid vehicle 20 of the embodiment includes the engine 22, the planetary gear 30, the motors MG1 and MG2, the battery 50, and the outlet 52. However, the hybrid vehicle 20 may be a vehicle that travels using the power from the engine and the power from the motor. For example, the motor MG3 may not be provided, or the planetary gear 30, the motor MG1, and the motor MG3 may not be provided.
