Method ofr controlling the displacement of a part, displaced by an electromotor, of a closure device in a motor vehicle

The invention relates to a method for controlling the displacement motion of a part, moved by an electromotor, of a closure device in a motor vehicle, for example, a window pane control, in the doors of the motor vehicle. A jamming incident is identified by a comparison of at least one status value of the electromotor or of the closure device which status value signifies a jamming incident, for example the motor current or the displacement speed, which a characteristic value that is significant for a jamming incident. In addition, the position of movable body parts, in particular the doors, is detected and the control of the displacement motion is adapted, in accordance with the identification of a jamming incident and the position of the body parts. If the result of the comparison indicates a jamming incident, the electromotor is Stopped for a predetermined short period of time that is preferably hardly perceptible, or the motor is reversed. A verification is made whether, based on a predetermined first position of the body part, the position has altered or is altering during a predetermined time range prior to and/or after the occurrence of the comparison result that indicates a jamming incident. If this is the case, the displacement motion is continued in the closure direction, if not, it is assumed that a jamming incident has occurred and the electromotor is reversed, or the reversing action is continued. The Stopping or reversing time period is preferably of such a short duration that the displacement motion of the moving part in the opposite direction is not perceptible, at least to the naked eye.
