Abstract

The invention relates to a process for controlling an automated friction clutch with a wear adjustment device that adjusts extended clutch stroke by a discrete magnitude through the wear of friction lining at maximum transmittable torque of the friction clutch. To guarantee safe self-adjustment, also during a long operation period under the maximum clutch torque, under specified preconditions, for instance, during the start of the internal combustion engine and without gear engagement, the friction clutch is closed for maximum clutch torque.
