| 1. A method for controlling a non-self-locking clutch actuatable by a clutch actuating system on the basis of electric power,
between a drive unit and a transmission, and having a control device controlling the clutch actuating system and determining,
using measured data of a sensor, a clutch position, the method, to verify a clutch reference position, comprising the steps
of:
powering down the clutch actuating system for a predetermined first passive period of time or until an actuator stoppage occurs;
then determining the achieved clutch position in a first measurement and supplying electric power to the clutch actuating
system for a predetermined active period of time;
then powering down the clutch actuating system again for another predetermined passive period of time or until another actuator
stoppage occurs;
then determining the clutch position in another measurement; and
then checking the measured clutch position to determine whether the clutch position measured by the first or other measurement
can be verified as a new clutch reference position.
