Abstract
The displacement of a part e.g. window driven by an electromotor in a vehicle is controlled. A jam is identified by comparing a status value (e.g. current or speed) of the electromotor or the closure device with a characteristic value indicating a jam. The position of e.g. the part is detected. The displacement is controlled based on the identification of a jam and the position of the part. If a jam is indicated, the electromotor is stopped for a short time or is reversed. It is determined whether the position of the part has altered or is altering before and/or after the indicated jam. If so, the closing motion is continued, if not, it is assumed that a jam has occurred and the electromotor is reversed. The stopping or reversing time period is so short to be imperceptible to the naked eye.
