Process for controlling an adjusting drive for an electrically operated motor vehicle window with jamming protection

1 . Method of controlling an adjusting drive for electrically actuated window panes in motor vehicles, said method comprising the steps:

dividing a range of motion when lifting the window pane from an open position toward a closed position into a first range (B 1 ) and a second range (B 2 );

manually controlling said lifting when said window pane is in said first range, whereby the operating element must be operated for the lifting motion, and when the operating element is released, the lifting of window pane is stopped; and

automatically implementing the lifting motion of the window pane after a brief operation of the operating element when said window pane is in said second range.

2 . Method according to claim 1 , wherein

the first range of the lifting motion of the window pane is defined by the size of a shearing gap which occurs between a side edge of the window pane and a B-column of the motor vehicle.

3 . Adjusting drive according to claim 2 , wherein

the first range is defined as a section of the motion of the window pane in which the shearing gap is larger than 4 mm.

4 . A method of controlling movement of a motor vehicle window, comprising the steps:

controlling a first movement of said window from a first position to a second position by continuous activation of an operation element; and

providing automatic second movement of said window from said second position to a third position by a brief activation of said operating element.

5 . The method of claim 4 , wherein

said second position is defined by a predetermined shearing gap between said window and a column of said automobile.

6 . The method of claim 4 , wherein

said third position is a closed position of said window, and

said first position is a fully open position of said window.
