Abstract

The invention relates to a method for referencing a zero point of a self-closing clutch (2) in a motor vehicle, wherein a clutch actuator (7) is actuated, which is moved against a stop, wherein the clutch actuator (7) has an actuator force characteristic curve. In a method in which it is avoided that the clutch actuator (7) lifts off from and impacts again the throwout bearing (4) of the clutch (2) or the tongues (3) of the diaphragm spring, the referencing occurs against the stop with the clutch (2) open, wherein the stop has greater stiffness than the actuator force characteristic curve of the clutch actuator (7).
