Control device for a monitoring system of a motor vehicle, monitoring system, and motor vehicle

A control device for a monitoring system of a motor vehicle to monitor at least one function of the motor vehicle, the control device comprising:

• at least one computing unit to evaluate output signals, supplied to the control device and originating from a sensor of the monitoring system corresponding to the function, and to control a power electronics of an actuator of the monitoring system corresponding to the function via at least one control signal depending on the output signals for the execution of the function of the motor vehicle,
• wherein the control device is a single control device of the monitoring system, and
• wherein the control device has a total of three FOC computing units and is designed and set up such that, exclusively via the control device, a primary function of the motor vehicle and a secondary function of the motor vehicle during normal operation of the control device in which all three FOC computing units are functioning properly, and during an emergency operation of the control device, in which only one of the three FOC computing units is not functioning properly, the primary function is monitored.
