Abstract:
A method and apparatus for setting the torque transmitted by a friction clutch via an actuator chain having an electric motor, a reduction gear and a mechanism for converting the rotary movement of the electric motor. In the method, a desired angle of rotation of the electric motor or a link of the actuator chain is determined from the torque to be transmitted by the friction clutch and is set in a setting procedure based on a given torque/angle dependence. To compensate for wear inside the friction clutch, a calibration process takes place in which a first correction angle is determined for the torque/angle dependence. Variations in a torque/power consumption dependence caused by wear within the actuator chain are also taken into account. Specifically, the number of setting procedures of the electric motor within a predetermined time interval is determined and is used to correct the torque/power consumption dependence.
