Abstract
A steering system for a motor vehicle with at least one steerable wheel, one actuator, and one auxiliary drive. The auxiliary drive superimposes the steering motion initiated by the driver of the vehicle and the motion initiated by the actuator to generate the steering motion of the steerable wheel. A yaw parameter representing the yawing motion of the vehicle is detected, and a control signal is calculated when a predetermined running condition prevails, dependent at least on the detected yaw parameter. The actuator is then controlled by the generated control signal to initiate the motion. A braking parameter representing the braking condition of the vehicle is also detected, and the existence of the running condition is determined dependent on this detected braking parameter whereby yaw behavior is improved. Active steering intervention is switched in only when an external disturbance of vehicle motion is detected.
