Abstract

A vehicle includes a high-voltage battery, a socket for connection of a charging cable of an external power supply apparatus for charging the high-voltage battery, and a load for cooling and heating and a load for warming-up an engine that serve as in-vehicle loads receiving electric power from the high-voltage battery or an auxiliary machinery battery and controlled by a control device. The control device drives the in-vehicle electric load in response to disconnection of the charging cable from the socket. Preferably, the control device stops the in-vehicle electric load that has been driven when a prescribed stop condition is satisfied.

Claims

1. A control device of a vehicle, said vehicle including a power storage apparatus, a charge port for connection of a charging cable of an external power supply apparatus for charging said power storage apparatus, and an in-vehicle electric load controlled by said control device, comprising:

a drive start determination portion driving said in-vehicle electric load in response to disconnection of said charging cable from said charge port.

2. The control device of a vehicle according to claim 1, wherein

said in-vehicle electric load includes an air-conditioning apparatus, and

said control device causes said air-conditioning apparatus to perform preliminary air-conditioning before a driver gets in the vehicle in response to disconnection of said charging cable from said charge port.

3. The control device of a vehicle according to claim 1, wherein

said vehicle is a hybrid vehicle in which an internal combustion engine and a motor are used for driving wheels,

said in-vehicle electric load includes a load for warming up said internal combustion engine, and

said control device causes said load for warming-up to perform warm-up before a driver gets in the vehicle in response to disconnection of said charging cable from said charge port.

4. The control device of a vehicle according to claim 1, further comprising a stop determination portion stopping said in-vehicle electric load that has been driven when a prescribed stop condition is satisfied.

5. The control device of a vehicle according to claim 4, wherein

said prescribed stop condition includes connection again of said charging cable to said charge port after said in-vehicle electric load was driven.

6. The control device of a vehicle according to claim 4, wherein

said prescribed stop condition includes lapse of a prescribed time since said in-vehicle electric load was driven.

7. The control device of a vehicle according to claim 4, wherein

said prescribed stop condition includes a condition that the vehicle has attained a target state as a result of actuation of said in-vehicle electric load after said in-vehicle electric load was driven.

8. The control device of a vehicle according to claim 1, further comprising a prohibition determination portion prohibiting drive of said in-vehicle electric load in response to a prescribed prohibition condition being satisfied.

9. The control device of a vehicle according to claim 8, wherein

said prescribed prohibition condition includes an input to designate prohibition of preliminary drive of said in-vehicle electric load from a manipulation portion.

10. The control device of a vehicle according to claim 8, wherein

said prescribed prohibition condition includes a charged state of said power storage apparatus being lower than a prescribed value.

11. The control device of a vehicle according to claim 8, wherein said prescribed prohibition condition includes detection of abnormality in a result of failure diagnosis.

12. The control device of a vehicle according to claim 1, further comprising a display portion provided around said charge port, for indicating drive of a vehicle load in response to disconnection of said charging cable.

13. The control device of a vehicle according to claim 1, further comprising a manipulation portion provided around said charge port, for giving an instruction to prohibit drive of a vehicle load in response to disconnection of said charging cable.

14. A vehicle comprising the control device of a vehicle according to claim 1.
