Abstract

In a method and a device for operation of a cover of a tilt-and-slide sunroof of a vehicle, the cover is arranged in a first relative position in relation to a roof panel surrounding the cover when the vehicle is stationary. The cover is 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. A physical variable correlating with the vacuum force is registered, and adjustment of the position of the cover by 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, is performed. In its closed position, therefore, the cover always lies in the same relative position to the roof panel surrounding it, regardless of the vehicle speed.
