Patent ID: 8600612

Claim:
A method for determining wear of a friction plate of an automatically actuated friction clutch, in particular in a motor vehicle driven by an internal combustion engine, the method comprising: determining and storing an earlier clutch actuation travel ( 114 , 214 ) at a prescribed clutch slip and a prescribed clutch torque ( 112 , 212 ) in an earlier friction lining test point ( 104 , 204 ); determining a later clutch actuation travel ( 116 , 216 ) at the prescribed clutch slip and the prescribed clutch torque ( 112 , 212 ), in a later friction lining test point ( 108 , 208 ); determining a differential value ( 110 , 210 ) by comparing the earlier clutch actuation travel ( 114 , 214 ) and the later clutch actuation travel ( 116 , 216 ) to each other; and, determining a friction lining wear using the differential value ( 110 , 210 ).
