Abstract: A method and apparatus is for influencing a vehicle behavior of a vehicle in which a setpoint for a steering wheel actuator of a steering system, in particular of a steer-by-wire steering system, is determined independently of a setpoint for a wheel steering gear actuator, and the steering wheel actuator is actuated depending on the setpoint for the steering wheel actuator. The method further includes determining a setpoint for a wheel steering gear actuator of the steering system independently of the setpoint for the steering wheel actuator, and the wheel steering gear actuator is actuated depending on the setpoint for the wheel steering gear actuator. The setpoint for the steering wheel actuator is determined depending on a target value for influencing the steering wheel actuator.

Abstract: An apparatus for operating a motor vehicle, wherein the steering system comprises an actuatable steering handle and a steerable wheel, wherein the steering handle is mechanically decoupled from the wheel such that an actuation of the steering handle is independent from a steering of the wheel, wherein the steering handle is associated with a controllable steering handle actuator for generating a torque acting on the steering handle, and wherein the wheel is associated with a controllable wheel actuator for influencing a wheel steering angle of the wheel, with a computing device configured to control the steering handle actuator and the wheel actuator. The computing device is configured to specify a target manual torque (HMTarget) for the steering handle as a function of a target variable specified by a driving assistance system and to control the steering handle actuator as a function of the specified target manual torque (HMTarget).

Abstract: A method for determining a rack-and-pinion position in a steering system having an electric servomotor and a rack includes determining kinematic changes in a transmission path between the servomotor and the rack. The method further includes generating an event signal when a kinematic or dynamic rotor size of the servomotor exceeds an assigned threshold value.
