Abstract

An electronic control unit is configured to execute control for executing the external power supply by selecting one of a first power supply mode in which the engine and the generator are actuated to execute the external power supply and a second power supply mode in which the engine and the generator are stopped and the external power supply is executed by using the electric power stored in the power storage device, acquire a current location of the hybrid vehicle, acquire first information indicative of an area where an idle operation of the engine during parking is prohibited, and select the second power supply mode when the current location is in the area indicated by the first information at the time of executing the external power supply.

Claims

1. A hybrid vehicle configured to execute external power supply for supplying electric power from the vehicle to outside of the vehicle, the hybrid vehicle comprising:

a power storage device;

an engine;

a generator configured to generate the electric power by using output of the engine; and

an electronic control unit configured to

execute control for executing the external power supply by selecting one of a first power supply mode in which the engine and the generator are actuated to execute the external power supply and a second power supply mode in which the engine and the generator are stopped and the external power supply is executed by using the electric power stored in the power storage device,

acquire a current location of the hybrid vehicle,

acquire first information indicative of an area where an idle operation of the engine during parking is prohibited, and

select the second power supply mode when the current location is in the area indicated by the first information at the time of executing the external power supply.

2. The hybrid vehicle according to claim 1 further comprising a detector configured to detect a situation around the hybrid vehicle, wherein

the electronic control unit is configured to select the second power supply mode when the electronic control unit determines that the hybrid vehicle is located indoors on the basis of second information output by the detector and the current location is not in the area.

3. The hybrid vehicle according to claim 1 further comprising a detector configured to detect a situation around the hybrid vehicle, wherein

the electronic control unit is configured to execute the external power supply in a mode selected by a user from the first power supply mode and the second power supply mode when the current location is not in the area and the electronic control unit determines that the hybrid vehicle is located outdoors on the basis of second information output by the detector.

4. The hybrid vehicle according to claim 1 further comprising an alarm configured to notify the user of selection of the second power supply mode due to a fact that the current location is in the area when the current location is in the area at the time of executing the external power supply.

5. The hybrid vehicle according to claim 1, wherein the electronic control unit is configured to acquire the first information from a server located the outside of the vehicle via a communication network.

6. The hybrid vehicle according to claim 1 further comprising a storage device configured to store the first information, wherein

the electronic control unit is configured to acquire the first information from the storage device.

7. A control method of a hybrid vehicle configured to execute external power supply for supplying electric power from the vehicle to outside of the vehicle, the hybrid vehicle including a power storage device, an engine, a generator configured to generate the electric power by using output of the engine, and an electronic control unit,

the control method comprising:

executing, by the electronic control unit, the external power supply by selecting one of a first power supply mode in which the engine and the generator are actuated to execute the external power supply and a second power supply mode in which the engine and the generator are stopped and the external power supply is executed by using the electric power stored in the power storage device;

acquiring, by the electronic control unit, a current location of the hybrid vehicle;

acquiring, by the electronic control unit, first information indicative of an area where an idle operation of the engine during parking is prohibited; and

selecting, by the electronic control unit, the second power supply mode when the current location is in the area indicated by the first information at the time of executing the external power supply.
