Method and device for determining an engagement point of a hybrid clutch in a hybrid vehicle

A method for determining an engagement point of a hybrid clutch of a hybrid vehicle, which is operated by a hydrostatic clutch actuator, with the hybrid clutch separating an internal combustion engine from an electric traction drive or connecting them, the method of determining the engagement point comprising:

• operating the hybrid clutch, starting from a position of the hybrid clutch that the clutch assumes in a disengaged condition, while monitoring a torque of the electric traction drive,
• when a defined increase in the torque is detected, adapting a presently given engagement point (tp) during operation of the hybrid vehicle using a start-up routine for adaptation of the presently given engagement point (tp) during operation by which a first engagement point is determined during a start-up operation of the hybrid vehicle in which the hybrid clutch approaches a previously determined engagement point and further displacing the hybrid clutch starting from said previously determined engagement point until the defined increase in torque is detected.
