  • Patent number: 7000982
    Abstract: In a process for controlling a closing device in a motor vehicle driven by an electric motor, in particular for controlling a motor vehicle sunroof, to protect a body part from being crushed during a closing motion, a closing resistance variable is detected. The closing resistance variable is characteristic of a force counteracting the closing motion, and is used to determine whether a crush situation exists. For this purpose, an additional auxiliary variable indicative of wind load forces at a certain speed is used. If a crush situation exists, a protective measure is initiated.

  • Patent number: 6729683
    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.

  • Patent number: 6688683
    Abstract: A method for the operation of the cover of a slide-and-tilt sunroof for closing a roof opening of a vehicle from an open position, at least partially exposing the roof opening is provided. To close it, the cover is slid into the area of the roof opening and moved towards an opening edge of the roof opening, and, after commencement of the movement towards the opening edge of the roof opening, the movement of the cover is driven in such a way that the cover reaches the closed position in the same closing direction as when closing from its elevated position.
