ABSTRACT:
A method for automatically adjusting slip in an automatic friction clutch arranged between an engine and a gearbox of a motor vehicle. The clutch has a clutch-adjusting positioning drive which adjusts the clutch to a position which is defined by a position set-point signal. The clutch input speed and the clutch output speed are detected using speed sensors and a position set-point signal is produced according to the difference of the speeds (slip speed). The slip speed is equal to a predefined set slip value and is used as a control variable for the transmitted clutch torque. An engine torque is used as a control variable for the clutch instead of the clutch torque or as a complement thereto.
