Abstract:
A method of controlling an automated friction clutch in a drivetrain of a motor vehicle between a drive motor and a manual transmission. During clutch actuation, at least one operating parameter of the friction clutch is detected by a sensor and from variation of the operating parameter at least one adaptation parameter is derived for correcting a control parameter of the associated clutch control element. To obtain information about variation of the clutch release force and to improve the control of an associated clutch control element, the friction clutch is fully disengaged with constant control or actuation of the clutch control element. During the disengagement process, the release travel path is determined as a function of release time, and from the time variation of the release travel path, a characteristic value is determined which is used to determine an adaptation parameter for correcting the control parameter of the clutch control element.
