Abstract

1. Method for operating the electric window openers of a motor vehicle.

2.1 A simple, cost-effective and user-friendly method for sequentially controlling the action of the window openers for moving the front window pane and the rear window pane is proposed.

2.2 For this purpose, the window openers on one side of the motor vehicle are operated by the actuation of a single operating element. The sequence for moving the front window pane and the rear window pane is controlled as a function of the selection made by the operating element of the direction of movement and of the mode of movement of the window panes and of the position of the rear window pane; in the case of motor vehicles having a movable roof, the position of the roof of the motor vehicle is additionally used for the sequential control.

Claims

1. A method for operating the electric window openers of a motor vehicle, characterized in that the window openers for moving the front window pane (FWP) and the rear window pane (RWP) on one side of the motor vehicle are operated by the actuation of a single operating element, and in that the sequence for moving the front window pane (FWP) and the rear window pane (RWP) is controlled as a function of the selection made by operating element of the direction of movement and of the mode of movement of the window panes and of the position of the rear window pane (RWP).

2. The method as claimed in claim 1, characterized in that in motor vehicles having a movable roof, the sequence for moving the front window pane (FWP) and the rear window pane (RWP) is controlled as a function of the position of the roof of the motor vehicle.

3. The method as claimed in claim 1 or 2, characterized in that if the closing direction is selected by the operating element as the direction of movement, firstly the front window pane (FWP) and then the rear window pane (RWP) is raised in a sequential raising operation.

4. The method as claimed in claim 3, characterized in that if the automatic function is selected by the operating element as the mode of movement, only the front window pane (FWP) is automatically raised.

5. The method as claimed in claim 1 or 2, characterized in that if the opening direction is selected by the operating element as the direction of movement when the roof is closed and the rear window completely closed, firstly the front window pane (FWP) and then the rear window pane (RWP) is lowered in a sequential lowering operation.

6. The method as claimed in claim 1 or 2, characterized in that if the opening direction is selected by the operating element as the direction of movement when the roof is open or when the roof is closed and the rear window is not completely closed, the front window pane (FWP) and the rear window pane (RWP) are simultaneously lowered in a common lowering operation.

7. The method as claimed in either of claims 5 and 6, characterized in that the rear window pane (RWP) is lowered automatically.

8. The method as claimed in one of claims 1 to 7, characterized in that the rear window pane (RWP) is not moved in a sequential raising operation or a sequential lowering operation until the front window pane (FWP) has reached its particular end position and the particular direction of movement is selected by the operating element.
