Abstract:
Method for determining wear of a friction plate of an automatically actuated friction clutch, particularly in a motor vehicle driven by an internal combustion engine, wherein initially at a prescribed clutch slip and a prescribed clutch torque in an earlier friction lining test point an earlier clutch actuation travel is determined and stored, later again at the prescribed clutch slip and the prescribed clutch torque in a later friction lining test point a later clutch actuation travel is determined, thereafter the earlier clutch actuation travel and the later clutch actuation travel are compared to each other and a differential value is determined, and thereafter a friction lining wear is determined using the differential value, in order to reliably determine friction lining wear in a time interval and with only little effort, so that a depreciation of function due to a worn friction lining can be prevented in a timely manner.
