Abstract

A feed system includes a vehicle and a feed mode controller. The feed system feeds electric power to an electric load outside the vehicle in a first feed mode or a second feed mode. A wireless communication device of the vehicle communicates in a first communication system in which communication with a portable terminal is established without passing through a relay point. The feed mode controller enables the first feed mode to be selected when the communication in the first communication system is established, and disables the first feed mode from being selected when the communication in the first communication system is not established.

Claims

1. A feed system configured to feed electric power in one of a first feed mode and a second feed mode, the feed system comprising:

a vehicle including an engine, an electric power generating device, an electric storage device, an outlet and a wireless communication device, the electric power generating device being configured to generate electric power by dynamic power of the engine, the outlet being configured to be connected to an electric load outside of the vehicle, the wireless communication device being configured to perform wireless communication in at least one of a first communication system and a second communication system, the first communication system being a communication system in which communication with a portable terminal is established without passing through a relay point, the second communication system being a communication system in which the communication with the portable terminal is established while passing through the relay point; and

a feed mode controller configured to enable the first feed mode to be selected by an operation of the portable terminal when the communication in the first communication system is established between the portable terminal and the vehicle, and

the feed mode controller being configured to disable the first feed mode from being selected by the operation of the portable terminal when the communication in the first communication system is not established between the portable terminal and the vehicle, the first feed mode being a mode in which electric power of at least one of the electric power generating device and the electric storage device is supplied to the electric load when actuation of the engine is allowable, and the second feed mode being a mode in which electric power of the electric storage device is supplied to the electric load when the engine is stopped.

2. The feed system according to claim 1, wherein

the feed mode controller is configured to enable the second feed mode to be selected when the communication in the first communication system is established between the portable terminal and the vehicle.

3. The feed system according to claim 1, wherein

the feed mode controller is configured to enable the second feed mode to be selected when the communication in the second communication system is established between the portable terminal and the vehicle.

4. The feed system according to claim 2, wherein

the feed mode controller is configured to disable each of the first feed mode and the second feed mode from being selected when the communication in the first communication system is not established between the portable terminal and the vehicle.

5. The feed system according to claim 1, wherein

the feed mode controller is configured to prohibit the first feed mode from being selected when a selection request for the first feed mode is sent from the portable terminal and the communication in the first communication system is not established between the portable terminal and the vehicle.

6. The feed system according to claim 1, wherein

the portable terminal includes a display device,

the display device is configured to display a selection screen for the first feed mode and the second feed mode, and

the feed mode controller is configured to disable the first feed mode from being selected on the selection screen of the portable terminal when the communication in the first communication system is not established between the portable terminal and the vehicle.

7. The feed system according to claim 1, further comprising

a feed controller configured to enable a preset action about the feed of the electric power by the operation of the portable terminal when the feed of the electric power to the electric load is started and the communication in one of the first communication system and the second communication system is established.

8. The feed system according to claim 7, wherein

the preset action includes at least one of an action of changing a first threshold of a state-of-charge of the electric storage device, an action of changing a second threshold of a remaining level of fuel for the engine, and an action of stopping the feed of the electric power,

the first threshold being a threshold for giving a notice of information about the state-of-charge, and

the second threshold being a threshold for giving a notice of information about the remaining level of the fuel.

9. A vehicle comprising:

an engine;

an electric power generating device configured to generate electric power by dynamic power of the engine;

an electric storage device;

an outlet configured to be connected to an electric load outside of the vehicle;

a wireless communication device configured to perform wireless communication in at least one of a first communication system and a second communication system, the first communication system being a communication system in which communication with a portable terminal is established without passing through a relay point, and the second communication system being a communication system in which the communication with the portable terminal is established while passing through the relay point; and

an electronic control unit configured to execute feed of electric power in one of a first feed mode and a second feed mode, the first feed mode being a mode in which electric power of at least one of the electric power generating device and the electric storage device is supplied to the electric load when actuation of the engine is allowable, the second feed mode being a mode in which electric power of the electric storage device is supplied to the electric load when the engine is stopped,

the electronic control unit being configured to enable the first feed mode to be selected by an operation of the portable terminal only when the communication in the first communication system is established between the portable terminal and the vehicle.
