The invention relates to a method for regulating an actual speed of the working stroke of a motor-vehicle window-pane, during its displacement from a closed position into an open position and vice versa and to a device which is suitable for carrying out said method, whereby the window-pane can be actuated using an electromotive drive (12) and a window-lift device. According to the invention, the supply of electrical power (18) to the drive (12) is controlled by a control system, such as a burst control system or similar, in such a way that the actual speed of the window-pane during a working stroke remains stable in the long-term, in particular with regard to temperature, wear, or age-dependent influences and that the electrical power supply (18) is controlled according to a comparison of the predetermined speed (24) and the actual speed (20) of the drive (12). |
