Claim 0:
1. A control system for a motor vehicle, the control system comprising:
a first control unit;
a first power electronics unit connected in a signal-transmitting manner to the first control unit for supplying power to a first actuator in normal operation of the control system;
a backup control unit; and
a backup power electronics unit connected in a signal-transmitting manner to the backup control unit for supplying power to the first actuator in a first backup operation of the control system,
wherein the backup control unit is connected to the first control unit in a signal-transmitting manner,
wherein the control system is transferred from the normal operation to the first backup operation as a function of the arrival in the backup control unit of a fault signal from the first control unit, and
wherein in the first back up operation, the first power electronics unit is galvanically isolated from the first actuator via at least one first disconnect switch per phase of the first power electronics unit and the backup power electronics unit is galvanically connected to the first actuator via at least one first connecting switch per phase of the backup power electronics unit.
