<p>The invention concerns a method for the contactless approach of the lower stop position of a motor vehicle window operated by extraneous force. While the window is being lowered, the drive generates position sensor signals which are relayed to an electronic evaluation unit and counted, the drive being switched off when it reaches a given count. While the drive is being operated, in order to lower the window in a first phase of its adjusting movement, the position sensor signals are associated with the compensation of the deficiencies in the window-raising mechanism system and, in a second phase of its adjusting movement, they are associated with the displacement of the window-lowering system. During the second phase of the adjusting movement of the drive, a slowing-down path to be expected is calculated on the basis of the window-lowering speed and/or the operating voltage. When the window position which is at a distance before the position of the established contactless lower stop which corresponds to the length of the slowing-down path is reached, the window-raising drive is stopped.</p> |
