Abstract

A control system for a motor vehicle having a first control unit and having 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. In order to ensure proper operation of a control system for a motor vehicle, even in the event of a fault, the control system has 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. The backup control unit is connected to the first control unit in a signal-transmitting manner. The control system is transferred from normal operation to the first backup operation as a function of the arrival in the backup control unit of a fault signal.
