Abstract
A device for controlling a movable member for closing or clearing an opening, such as a sliding roof or a window in a door of a vehicle, a direct-current motor being arranged for driving the movable member, and detection means being arranged for detecting a body being caught between the movable member and an edge of the opening. The detection means are arranged to measure the motor current flowing through the direct-current motor and, upon detection of a predetermined increase of the motor current, or a related quantity, to provide a body-caught detection signal. Further, a position sensor is provided, which can measure the displacement of the movable member. A body-caught detection signal is transmitted only after the position sensor has indicated that the movable member has begun to move.
