Abstract
A method of and an arrangement for preventing a shift of the reference position of a clutch which is operated by an actuator and is installed in the power train of a motor vehicle. Such shift of reference position can be caused in response to axial displacements between the input and output shafts of the clutch. The method includes the steps of routinely ascertaining the reference position, memorizing and thus actualizing the information pertaining to the ascertained reference position, ascertaining an operational parameter which is the cause of axial displacements between the input and output shafts of the clutch, and altering the routine determination and the memorizing of the reference position when the operational parameter exceeds a predetermined threshold value.
