Abstract
A method of determining a touch-point of a friction clutch of a motor vehicle that is relevant for control purposes such that a current, actual touch-point of the friction clutch is determined adaptively, and such that the current touch-point is modified, with a correction value that depends on the elasticity of the friction clutch, in order to determine the control-relevant touch-point. The control device comprises elements for carrying out the method.
