  • Patent number: 5853064
    Abstract: A steering system for a motor vehicle comprising at least one steered wheel, an actuator motor and an actuator, wherein the steering movement initiated by the driver of the vehicle and the movement initiated by the actuator motor are superimposed by the actuator to generate a movement of the steered wheel. The actuator motor is activated for movement by a manipulated variable that depends at least on the steering movement initiated by the driver. Significant for the invention is that the manipulated variable is limited in magnitude. The difference between the manipulated variable and a restricted manipulated variable in parallel through an integrated stage and is superimposed upon the manipulated variable to prevent the vibration of a released steering wheel.
