Lift-up vehicle sunroof with wind load compensation and method for operating the same

摘要

A method and a device for the operation of a cover of a tilt-and-slide sunroof of a vehicle, the cover being arranged in a first relative position in relation to a roof panel surrounding the cover when the vehicle is stationary, and the cover being moved from the first relative position into a second relative position by a vacuum force caused by an air stream when the vehicle is in motion, having the following stages in particular: ;a) registering (12, 14) of a physical variable correlating with the vacuum force; ;b) adjustment (13) of the position of the cover by means of the cover drive as a function of the variable registered, counter to the direction of the vacuum force from the second relative position into a third relative position essentially coinciding with the first relative position. ;It is thereby ensured that in its closed position the cover always lies in the same relative position to the roof panel surrounding it, regardless of the vehicle speed.
