Patent ID: 8651256

Claim:
A method for determining a wear condition of a shifting clutch of a motor vehicle in which the clutch is provided for one of interrupting a force flow and equalizing a rotational speed between a drive output shaft of an internal combustion engine and a drivetrain of the motor vehicle, the method comprising the steps of: moving the clutch along a clutch release path during a single clutch actuation, detecting a first location of the clutch along the clutch release path where, at a start of the clutch actuation, an initial increase of a release force in a release bearing occurs, detecting a second location of the clutch along the clutch release path where, during the single clutch actuation, and after both the initial increase of release force and a decrease in the release force on the release bearing, a subsequent increase of the release force in the release bearing occurs, defining the second location as a reference point value, defining a distance between the first location and the second location along the release path as a path difference, and comparing the path difference to a first predefined limit to determine the wear condition of the clutch.
