Abstract

A method for referencing an incremental travel sensor in an electronically controlled actuation device of a clutch in the drive train of a traveling vehicle, the actuation device containing a memory in which a characteristic curve is stored that indicates the clutch torque as a function of the position of an actuation element, the method comprising the following steps: determining whether the clutch is slipping beyond a given threshold; if so, determining the current clutch torque; and determining the current position of the actuation element based on the current clutch torque and the characteristic curve. Additional methods are specified that facilitate a referencing according to requirements.
