Abstract: 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.

Abstract: A method and apparatus for limiting an assistance-torque demand on an actuator, for example a servomotor, of a power steering system. An assistance-torque demand is received and examined based on a predetermined limit criterion. If a violation of the limit criterion is ascertained, a transient assistance-torque limit is adopted and progressively reduced so long as the violation of the limit criterion is ascertained. The assistance-torque demand is limited based on the transient assistance-torque limit. The limited assistance-torque demand is sent to an interface of the actuator of the power steering system.

Abstract: A method for controlling cornering of a motor vehicle having a front wheel drive and an electronically controllable locking differential. A motion model of the motor vehicle is calculated on the basis of the control inputs of a vehicle driver, a lateral movement parameter of the motor vehicle is measured. Deviations of the measured lateral movement parameter to the modeled movement, and the rotational speed of a front wheel which is on the inside during cornering from such a rotational speed of a front wheel which is on the outside are determined. The deviations are reduced if the rotational speed of the front wheel which is on the inside is not lower than the rotational speed of the front wheel which is on the outside, and if the measured lateral movement parameter deviates from the modeled lateral movement parameter. Reduction of the deviation is carried out by applying a locking torque to the locking differential and by single-sided braking of at least one wheel.
