摘要:
A method for adapting a contact point of a clutch in a drivetrain of a motor vehicle, wherein the clutch is moved by an actuator and the influence of the movement of the clutch on a rotating electric motor is evaluated. A method that is simple and quick to carry out, a clutch torque and/or an actuator path close to the contact point is obtained from a characteristic curve of the clutch representing the relationship of an actuator path to a clutch torque and is set at the clutch. Subsequently the associated actuator path and/or the clutch torque is measured from the clutch influenced by the actively operated electric motor, where the clutch torque read from the characteristic curve and the actuator path measured at the clutch and/or the actuator path obtained from the characteristic curve and the measured clutch torque form the current contact point position of the clutch.
