摘要： A power supply system for a vehicle has at least one control unit with two power supply terminals that are each protected against overload by a fuse. The first power supply terminal is connected to a voltage regulator for the microcomputer of the control unit and to the accumulator via the quiescent current switch, while the second power supply terminal is connected to the accumulator via a fuse. The first power supply terminal supplies the microcomputer with energy, while the second power supply terminal actuates one power switch per control unit in order to supply energy to the output stages of an actuator which is operated by the control unit. The on-board vehicle power system control unit activates the quiescent current switch in order to deactivate the microcomputer, while the power switches of the same control unit are supplied with power.
