  • Method for defined closure of a window pane of a motor vehicle
    Publication number: 20110225894
    Abstract: Disclosed is a method for closing a window pane of a motor vehicle with an externally powered motor vehicle window winder. When the window pane is closed in manual mode, a switch is made from manual mode to automatic mode when a minimum distance between the window pane and the pane seal is not reached, and here, the window pane is moved into the pane seal and the motor run is maintained even when an end position is reached until a defined blocking time is reached.
