A power steering assembly having an input shaft for connection to a steering wheel, an output shaft coupled to the input shaft for operational engagement with a steering rod, a servo controller, an actuator, a sensor system, and an evaluation unit for evaluating measurement values provided by the sensor system. The coupling between input and output shafts permits a relative rotation therebetween. The servo controller has a rotatable final control element with and driven by the output shaft. The steering force assistance is controlled depending on relative rotation between the input shaft and control element. The engagement between the output shaft and control element provides a relative displacement therebetween. The actuator relatively displaces the control element in relation to the output shaft. The sensor system measures at least one differential angle between the control element and output shaft or between the control element and input shaft. |
