Motor vehicle adjustment drive having angle measuring sensor

A motor vehicle adjustment drive, comprising:

• an electric motor;
• a control unit operable to activate the electric motor;
• a transmission having a self-locking transmission stage, a power takeoff, and a safety coupling operable to separate the self-locking transmission stage from an external torque in response to an excessive external torque introduced via the power takeoff, the safety coupling having a motor-side gearwheel having at least one coupling contour and at least one engaging contour, a power takeoff-side gearwheel, a free-running mechanism formed by the at least one coupling contour, and coupling elements operable to establish a positive-locking connection between the motor-side gearwheel and the power takeoff-side gearwheel such that the coupling elements are pressed in response to the excessive external torque out of the at least one coupling contour to separate the self-locking transmission stage from the external torque;
• at least one engaging element rotationally secure with respect to the motor-side gearwheel or the power takeoff-side gearwheel;
• at least one resilient element operable to pretension the at least one engaging element against the at least one engaging contour to enable haptics of an external movement request introduced via the power takeoff;
• and
• an angle measuring sensor operable to detect the external movement request, wherein the control unit activates the electric motor in response to the detection of the external movement request.
