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.
