Abstract
A device for controlling a steer-by-wire steering system in a vehicle, in which redundantly generated sensor signals for regulating a steering motor and for a feedback actuator that transfers the restoring torques from the road to the driver via the steering wheel are received by a control device and plausibility checks of the sensor signals are performed therein and in an operatively associated monitoring module. Microcomputer module and monitoring module monitor each other reciprocally. An auxiliary level for the SbW steering system is monitored by the control device which, in the case of error, switches to this auxiliary level or a mechanical auxiliary level. To further increase safety, the steering wheel motor is triggered via control signals for its phase currents and by a steering wheel motor enable signal, and the steering motor is triggered via control signals for its phase currents and via a steering motor enable signal.
