摘要： A steering system for a motor vehicle may include a steering wheel actuator mechanically connectable to a steering wheel of the motor vehicle, and a control unit operably coupled to the steering wheel actuator. The control unit may be configured to determine a target steering wheel torque via which the steering wheel actuator is activatable. The target steering wheel torque may be determined from a present state parameter of the motor vehicle using a steering wheel torque algorithm. The control unit may be configured to determine whether the target steering wheel torque is considered plausible or not plausible based on the present state parameter of the motor vehicle via a plausibility algorithm, determine a fallback steering wheel torque via an auxiliary algorithm, and use the fallback steering wheel torque instead of the target steering wheel torque as a target steering wheel torque request if the target steering wheel torque is not plausible.
