METHOD OF CALIBRATING CLUTCH ACTUATOR

The present invention relates to a method for calibrating a clutch actuator. The clutch actuator comprises a servomotor, a cam w, an adjusting element, and a sensor. The clutch actuator is characterized by comprising the following steps that first operation of the servomotor is conducted by a first stator space vector, so the cam can rotate in a first direction, and a first data group composed of the first position of the first space vector and the first actual position of the cam can be determined; second operation of the servomotor is conducted by a second space stator vector, so the cam can rotate in a second direction opposite to the first direction and a second data group composed of the second space vector position and the a second practical direction of the cam disc is determined. The clutch actuator is calibrated with the determined first and second data groups; by rotation of the cam via the first and second operation, the executing element can be applied against a bration zone of a constant radius o
