Process for controlling the displacement of the window pane of a motor vehicle door

Abstract

A method for controlling a movement of a window pane of a motor vehicle door immediately after the lowering of the window pane, until there is compensation of the system deficiency of the displacement mechanism caused by the displacement of the window pane into the lowering direction of movement. With a short stroke lowering of the upper edge of a free-standing frameless window pane from a keyed sealing engagement on the bodywork side, a signal is generated through opening of the door and passed to an electronics evaluation unit whereupon the drive of the window lifter is activated in the lowering direction until the window pane has moved from its closed position into a predetermined partially opened position. After closing the vehicle door, as a result of the generation of a further signal, the lowered window pane is automatically closed again. During control of the drive for the purpose of automatically lowering the window pane, a first phase of the drive movement is assigned to compensate the system deficiencies of the window lifting mechanism, and a second phase of the movement is assigned to a path of the window lowering.
