Abstract

A vehicle power supply system has a power supply unit for supplying power to each unit of a vehicle, a plurality of actuation units actuated by the power from the power supply unit, an operation unit arranged for each of the plurality of actuation units, and operated when actuating the corresponding actuation unit, and a control unit for performing a control of starting supply of power from the power supply unit to each of the plurality of actuation units according to the operation of the corresponding operation unit when an actuation condition of the actuation unit corresponding to the operation unit is satisfied.

Claims

1. A vehicle power supply system comprising:

a power supply unit for supplying power to each unit of a vehicle;

a plurality of actuation units actuated by the power from the power supply unit;

an operation unit arranged for each of the plurality of actuation units, and operated when actuating the corresponding actuation unit; and

a control unit for performing a control of starting supply of power from the power supply unit to each of the plurality of actuation units according to the operation of the corresponding operation unit when an actuation condition of the actuation unit corresponding to the operation unit is satisfied.

2. The vehicle power supply system according to claim 1, further comprising:

a replacement control unit for monitoring the control unit and a predetermined one of the plurality of actuation units, and performing the control of starting supply of power from the power supply unit to the predetermined actuation unit, on behalf of the control unit, with respect to the actuation unit that does not actuate although the control to start supply of power that is performed by the control unit.

3. The vehicle power supply system according to claim 1, wherein the actuation condition differs for each of the plurality of actuation units.

4. The vehicle power supply system according to claim 1, further comprising, for each of the plurality of actuation units, an actuation control unit for communicating with the control unit and changing a switch connected to the power supply unit to an ON state when receiving an operation signal from the operation unit.
