The invention relates to a device and a method for identifying an object O in an opening that can be closed by means of a mobile element (). Light is fed into at least one fiber-optic light guide () from a light source (), and variations in the received light are detected by means of at least one receiver (Ea, Eb), the fiber-optic light guide being arranged at least partially along the edge of the opening (). A first fiber-optic light guide sends light transversally to the length thereof, said light being then received by a second fiber-optic light guide transversally to the length thereof. The second fiber-optic light guide () is connected to the receiver (Eb). The fiber-optic light guides are arranged on the edge of the opening () in such a way that a light field (F) at least partially bridging the opening is produced. At least one light source () and at least one receiver (Ea, Eb) are respectively associated with each fiber-optic light guide (), and a clock circuit is used to alternately feed the light received by the respective receiver into the fiber-optic light guides. Comparison means are used to compare the signals on the receivers in order to identify the object.

Device and method for identifying an object in or on a closable opening

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.

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

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.

Method for operating a sliding-lifting roof

A display apparatus on the vehicle ceiling, in front of a partition wall which blocks the view of the rear window from the internal rear-view mirror, in order to display information, in particular about an area to the rear of the vehicle which is monitored by a monitoring device. When driving rearwards, the internal mirror is deflected, for example being pivoted automatically upwards from the position of the direction of travel selection lever, so that the driver can read the display, which is otherwise located outside the mirror field of view, via the rear-view mirror.

Display arrangement in a vehicle

The invention provides a method for evaluating the self-diagnostic system of a controller in a motor vehicle having a control panel with a push-button switch with automatic return, and additional input elements and having a signalling element which is suitable for emitting a flashing code. In order to emit a structured flashing code of fault numbers, the range of possible faults which can be diagnosed is divided into fault classes, the faults within a fault class being assigned fault numbers which can be emitted, separated on the basis of fault classes, by flashing code. A specific fault class is selected by the operator by setting the input elements to a specific position combination which is assigned to the fault class, and operation of the push-button switch (for example, the recirculation push-button in the case of a heating controller).
