Abstract

A vehicle control device mounted on a vehicle includes: an operation detection unit that detects an operation performed on the vehicle by a user; a power supply control unit that controls execution of power supply from a first battery involved in vehicle traveling to an auxiliary load powered by a second battery that is different from the first battery, with a start switch of the vehicle being off; and a prohibition control unit that prohibits the power supply to the auxiliary load by the power supply control unit, in response to the operation of the user detected by the operation detection unit.

Claims (26)

1. A vehicle control device mounted on a vehicle, the vehicle control device comprising a processor configured to, while a start switch of the vehicle is off:

detect a predetermined operation performed on the vehicle by a user, the predetermined operation being different from an operation for starting the vehicle;

control execution of power supply from a high-voltage battery to an auxiliary load, the high-voltage battery being involved in vehicle traveling, and the auxiliary load being powered by an auxiliary battery of which a rated voltage is set to be lower than that of the high-voltage battery; and

prohibit the power supply from the high-voltage battery to the auxiliary load in response to detecting the predetermined operation by the user.

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

the predetermined operation includes a first operation and a second operation that are different from each other, and

the processor is configured to, while the start switch is off,

prohibit the power supply from the high-voltage battery to the auxiliary load in response to detecting the first operation, and

lift prohibition of the power supply from the high-voltage battery to the auxiliary load in response to detecting the second operation in a state where the power supply from the high-voltage battery to the auxiliary load is prohibited.

3. The vehicle control device according to claim 2 , wherein the first operation is an operation of pressing a button of the start switch for a predetermined time or longer, or an operation of repeatedly pressing the button of the start switch a predetermined number of times or more.

4. A control method that is executed by a computer of a vehicle control device mounted on a vehicle, the control method comprising:

detecting, while a start switch of the vehicle is off, a predetermined operation performed on the vehicle by a user, the predetermined operation being different from an operation for starting the vehicle;

controlling, while the start switch is off, execution of power supply from a high-voltage battery to an auxiliary load, the high-voltage battery being involved in vehicle traveling, and the auxiliary load being powered by an auxiliary battery of which a rated voltage is set to be lower than that of the high-voltage battery; and

prohibiting, while the start switch is off, the power supply from the high-voltage battery to the auxiliary load in response to detecting the predetermined operation by the user.

5. A non-transitory storage medium storing a control program that is executed by a computer of a vehicle control device mounted on a vehicle and that causes the computer to execute functions comprising:

detecting, while a start switch of the vehicle is off, a predetermined operation performed on the vehicle by a user, the predetermined operation being different from an operation for starting the vehicle;

controlling, while the start switch is off, execution of power supply from a high-voltage battery to an auxiliary load, the high-voltage battery being involved in vehicle traveling, and the auxiliary load being powered by an auxiliary battery of which a rated voltage is set to be lower than that of the high-voltage battery; and

prohibiting, while the start switch is off, the power supply from the high-voltage battery to the auxiliary load in response to detecting the predetermined operation by the user.

6. A vehicle equipped with the vehicle control device according to claim 1 .

7. The vehicle control device according to claim 2 , wherein

the predetermined operation further includes a third operation different from the first operation and the second operation, and

the processor is configured to, while the start switch is off,

activate the execution of the power supply from the high-voltage battery to the auxiliary load in response to detecting the third operation,

stop the execution of the power supply from the high-voltage battery to the auxiliary load in response to detecting the first operation while the execution of the power supply from the high-voltage battery to the auxiliary load is activated, and

restart the execution of the power supply from the high-voltage battery to the auxiliary load in response to detecting the second operation after stopping the execution of the power supply from the high-voltage battery to the auxiliary load.

8. The vehicle control device according to claim 7 , wherein the processor is configured to, after the first operation is detected and until the second operation is detected, not activate the power supply from the high-voltage battery to the auxiliary load even when the third operation is detected.
