Abstract: A method and system for determining the point of engagement of a clutch of a motor vehicle operable via an actuating device, where the actuating device has an electrically drivable positioning motor that is operationally linked to an actuating mechanism which actuates the clutch and operates via a control unit. The point of engagement is determined through an application of a constant voltage to the positioning motor in a first operating mode. The motor speed is detected as a function of the rotational angle position. The motor current is detected as a function of the rotational angle position, and/or by application of a constant current to the positioning motor in a second operating mode. The point of engagement is determined from the detected values of the motor speed, that are a function of the rotational angle position and from the values of the motor current.

Abstract: A method and a system for determining the point of engagement of a clutch of a motor vehicle operable via an actuating device, in particular of a clutch situated in a transfer case of a motor vehicle having all-wheel drive, the actuating device having a positioning motor which is electrically drivable, the output of the positioning motor providing a motor torque and a motor speed, and the motor being operationally linked to an actuating mechanism which actuates the clutch and being operable via a control unit.
