Abstract
In order to transmit reliable and precise information, to as great an extent as possible, on current driving conditions and driving situations, and also achieve disturbance-free behavior of the steering system in the center point range, in a steering device in a vehicle, a target steering torque (torSSW) is determined by determining an actual toothed rack force (forRT), determining at least one first component for the target steering torque (torSSW) as a function of the actual toothed rack force (forRT), and determining at least one additional component for the target steering torque (torSSW) from a calculated toothed rack force (forRS), wherein the calculated toothed rack force (forRS) is determined from a wheel steering angle and a vehicle speed (velV).
