Abstract

A clutch actuation system includes an actuator drive for actuating the clutch, and a position control circuit having a controller determining a position of the clutch and to which a position setpoint value is fed and a measurement signal, representing the position, of a sensor is fed as an actual value. A filter that filters interference oscillations out of the position signal is inserted into the position control circuit. The stop band of the filter depends adaptively on the rotational speed of the drive engine of the motor vehicle, in particular, the stop band corresponds to the speed.
