Abstract

A vehicle includes a feeding system supplying an electric power to an external device disposed outside the vehicle, a controller controlling the operation of the feeding system, and an information output unit outputting predetermined information. The controller performs the processing of determining whether or not feeding can be performed from the feeding system to the external device. When the feeding from the feeding system to the external device is prohibited, the controller causes the information output unit to output prohibition information about the prohibition of the feeding including the contents of a determination processing.

First claim

The invention claimed is:

1. A vehicle comprising:
a feeding system configured to supply an electric power to an external device disposed outside the vehicle and including an engine that produces a motive power through combustion of a fuel and a generator that receives the motive power from the engine to generate an electric power;
a controller configured to control operation of the feeding system; and
an information output unit configured to output predetermined information, wherein
the controller is configured to determine whether or not a power feeding can be performed from the feeding system to the external device,
when a time period of power generation by the generator is longer than a set time, the controller is configured to determine that the power feeding to the external device cannot be performed, and
when the power feeding from the feeding system to the external device is stopped, the controller is configured to cause the information output unit to output stop information about the stop of the power feeding, the stop information including information about the time period of power generation.

2. The vehicle according to claim 1 , wherein
the feeding system includes a sensor configured to detect a remaining amount of the fuel,
the controller is configured to determine that the power feeding to the external device cannot be performed when the remaining amount detected by the sensor is less than a threshold value, and
the controller is configured to cause the information output unit to output the stop information including information about the insufficient remaining amount of the fuel.

3. The vehicle according to claim 1 , wherein
the controller is configured to determine whether or not the power feeding to the external device can be performed based on a state of the engine or the generator, and
the controller is configured to cause the information output unit to output the stop information including information about the state of the engine or the generator when the power feeding to the external device is stopped.

4. The vehicle according to claim 1 , wherein
the feeding system includes an electric storage apparatus outputting an electric power used in running of the vehicle and an electric power to be supplied to the external device,
the controller is configured to determine whether or not the power feeding to the external device can be performed based on a state of the electric storage apparatus, and
the controller is configured to cause the information output unit to output the stop information including information about the state of the electric storage apparatus when the power feeding to the external device is stopped.

5. The vehicle according to claim 1 , wherein the information output unit is a display or a speaker.

6. The vehicle according to claim 1 , wherein the information output unit is configured to transmit the stop information to a portable device.

7. The vehicle according to claim 6 , wherein the portable device has a display, and
the information output unit is configured to transmit information to be shown on the display as the stop information.

8. The vehicle according to claim 6 , wherein the portable device has a speaker, and
the information output unit is configured to transmit sound information to be output from the speaker as the stop information.

9. A control method of controlling a feeding system mounted on a vehicle and supplying an electric power to an external device disposed outside the vehicle, the feeding system including an engine that produces a motive power through combustion of a fuel and a generator that receives the motive power from the engine to generate an electric power, comprising:
determining whether or not a power feeding can be performed from the feeding system to the external device;
determining that the power feeding to the external device cannot be performed when a time period of power generation by the generator is longer than a set time; and
when the power feeding from the feeding system to the external device is stopped, outputting stop information about the stop of the feeding to the external device from an information output unit, the stop information including information about the time period of power generation.

10. The control method according to claim 9 , wherein the feeding system includes a sensor detecting a remaining amount of the fuel, the method further comprising:
determining that the power feeding to the external device cannot be performed when the remaining amount detected by the sensor is less than a threshold value, and
causing the information output unit to output the stop information including information about the insufficient remaining amount of the fuel when the power feeding to the external device is stopped.

11. The control method according to claim 9 , further comprising:
determining whether or not the power feeding can be performed on the basis of a state of the engine or the generator, and
causing the information output unit to output the stop information including information about the state of the engine or the generator when the power feeding to the external device is stopped.

12. The control method according to claim 9 , wherein the feeding system includes an electric storage apparatus outputting an electric power used in running of the vehicle and an electric power to be supplied to the external device, the method further comprising:
determining whether or not the power feeding can be performed on the basis of on a state of the electric storage apparatus, and
causing the information output unit to output the stop information including information about the state of the electric storage apparatus when the power feeding to the external device is stopped.

13. The control method according to claim 9 , further comprising causing the information output unit to transmit the stop information to a portable device.

14. The vehicle according to claim 6 , wherein the portable device is a remote key of the vehicle.

15. The control method according to claim 13 , wherein the portable device is a remote key of the vehicle.
