Device and Method for Controlling the Movement of a Both Motorically and Manually Movable Vehicle Part
First Claim
1. Device for controlling the movement of a both motorically and manually movable vehicle part, comprisinga drive unit controllable in its rotational speed for motorically moving the vehicle part,a coupling device for coupling the drive unit with the vehicle part anda control unit which controls the drive unit and the coupling device such that the coupling device, during a manual movement of the vehicle part, couples the drive unit with the vehicle part if the vehicle part has reached a pre-defined position,whereinthe control unit, for the coupling, controls the rotational speed of the drive unit in dependence of the moving speed of the vehicle part.

Abstract
A device for controlling the movement of a both motorically and manually movable vehicle part comprises a drive unit controllable in its rotational speed for motorically moving the vehicle part, a coupling device for coupling the drive unit with the vehicle part and a control unit which controls the drive unit and the coupling device such that during manually moving the vehicle part the coupling device couples the drive unit with the vehicle part if the vehicle part has reached a pre-defined position. For this, the control unit (3) controls the rotational speed of the drive unit (2) in dependence on the moving speed of the vehicle part (10). In this way a device and a method are provided which in an easy and low-wear manner allow for a control of the movement of a both motorically and manually movable vehicle part.
