ABSTRACT:
A process and device for the currentless referencing of a clutch position in non self-locking clutch actuating systems which are switched without current for a first predetermined, passive period of time or until an actuator standstill occurs, in order to verify a clutch reference position, then the clutch position achieved is determined by first measurement and current is supplied to the clutch actuating system for a predetermined, active period of time, the clutch actuating system being then switched again without current for another predetermined, passive period of time or until an actuator standstill occurs, the clutch position being determined by another measurement; finally the measured clutch position is checked to determine whether it can be verified as a new clutch reference position.
