Abstract: In a method and a device for adjusting a frameless window pane of a motor vehicle by means of a motorized window lifter activated by a control device, for adjusting the window pane between an open position and a closed position, in which the window pane upper edge is arranged in a window pane seal associated therewith and connected to the motor vehicle roof, the closed position of the window pane and/or the closing force with which the window pane bears against the window pane seal, is altered depending on the relative position of the window pane seal to the window pane upper edge. As a result, a connection of the window pane upper edge to the window pane seal which remains the same irrespective of the driving speed of the motor vehicle, is guaranteed and ensures that even at higher driving speeds there is no occurrence of leakages or increased wind noise.

Abstract: A method for calibrating a powered actuator for use in a vehicle is provided, with regard to an end position of an actuating element which is easy to achieve and conserves easily damaged mechanical components of the actuator made from plastic, rubber or similar. According to an example embodiement, in a calibrating step, the actuator is operated with recording and analysis of an actuation speed measured parameter such that the actuating element is moved in the direction of the end position and reaching the end position is recognized when the value of the actuation speed measured parameter reaches or drops below a given threshold. A temperature parameter characterizing the temperature of the actuator is evaluated before or during the calibration process. The calibration step is then only carried out if the value of the temperature parameter does not exceed an upper temperature limit. An actuator suitable for carrying out said method is also disclosed.
