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.

A method of determining a touch-point of a friction clutch of a motor vehicle, with the touch-point being relevant for control purposes, such that a current actual touch-point of the friction clutch is determined adaptively, the method comprising the steps of:
- modifying the current touch-point with a correction value that depends on an elasticity of the friction clutch in order to determine a control-relevant touch-point.
A control device of a motor vehicle for determining a control-relevant touch-point of a friction clutch of a motor vehicle, having a determining means for adaptive determination of a current touch-point of the friction clutch, and a modifying means for modifying the current touch-point with a correction value that depends on an elasticity of the friction clutch for determining the control-relevant touch-point of the friction clutch.
A method of determining a touch-point of a friction clutch of a motor vehicle that is relevant for control purposes, the method comprising the steps of:
- determining a correction value depending on an elasticity of the friction clutch;
- modifying a current actual touch-point of the friction clutch with the correction value;
- and
- defining a control-relevant touch-point as the modified current actual touch-point.
