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.

Steering system and method for operating a steering system

A present steering position of a manually actuatable steering unit of the motor vehicle is determined based on sensor data. A steering command is generated based on the present steering position of the steering unit. Then, based on sensor-detected present vehicle dynamics data, it is determined whether the motor vehicle is in a straight-ahead running situation during driving operation. It is determined whether, during the straight-ahead running situation of the motor vehicle, the present steering position of the steering unit deviates from a straight-ahead running position of the steering unit for at least one of a specified time period and a specified traveling distance of the motor vehicle. A compensation steering command is generated based on the determined deviation of the present steering position of the steering unit from the straight-ahead running position. A corrected steering command is generated based on combining the compensation steering command with the steering command.

Vehicle steering system

A motor vehicle has an electrically assisted steering system. A steering angle velocity of the motor vehicle, and a driver manual torque change applied by a driver of the motor vehicle are determined. At least the steering angle velocity and the driver manual torque change are analyzed to determine whether the driver manual torque change and the steering angle velocity are not correlated. An error signal is output if the driver manual torque change and the steering angle velocity are not correlated.
