Abstract: A method of activating surfaces which limit an inner space of a motor vehicle and are movable by adjusting drives, during occurrence of an accident event, includes the steps of providing the vehicle with occupant protection systems, releasing the occupant protection systems by a central control device, supplying to the central control device input signals of sensors which detect outer influences, inner influences or both, and moving the surfaces which limit the inner space by the central control device through in dependence on an accident event, to their opening position.

Abstract: A method of controlling a sliding roof, where braking of a vehicle is detected by a controller of the sliding roof device, and the pinch protection, i.e., the closing force limiter, is corrected so that faulty reversal of the sliding roof is suppressed when the vehicle is decelerating and the roof is being closed at the same time.

Abstract: The device for the detection of a wetting of a pane of glass, has an optical rain sensor which detects extraneous light and evaluates it for purposes of day-night detection. The amount of light striking the receiver (14) is integrated in an integration stage (16) and supplied to a comparator stage (20). The total light quantity formed by the light of a transmitter (12) and extraneous light and the extraneous light quantity detected when the transmitter (12) is switched off are measured in separate time intervals (Tg, Tf, Tf′). The time interval (Tf, Tf′) utilized for measurement of the extraneous light quantity is to be extended after a predeterminable number of measurement cycles (M) or after a predeterminable time period and/or the threshold (S2) is to be lowered for day-night detection.

Abstract: A method is proposed for positioning a part that is moveable by a drive back and forth between two end positions. For a predefined number of approaches toward one of the end positions, the drive is stopped before reaching this end position and its direction of rotation is changed, and during a subsequent approach toward the end position, the end position is reached, detected and stored for the purpose of normalization, the predefined number being generated in a control unit as random number.

Abstract: Proposed are a method and an apparatus for controlling a sliding and lifting sunroof device, which has a protection against wedging during closing of the cover (12) of the sliding and lifting sunroof from its raised position to its closed position, and which detects a situation of wedging of an object (20) wedged between the cover (12) and the opening of the sliding and lifting sunroof with the help of a sensor (34). Furthermore, for detecting a situation of wedging, provision is made for a water duct (18), which is movably arranged on the roof (14) of the motor vehicle within the opening of the sliding and lifting sunroof.

Abstract: An apparatus and a method for electronic monitoring of a positioning drive arranged in a motor vehicle are proposed, in which a processed speedometer signal is taken into account in an arrangement for making available at least one limit value of the closing force limiting system. This serves to prevent incorrect activation of the closing force limiting system.

Abstract: A device for collision protection of projecting parts of motor vehicles has a controllable actuating mechanism at least for retracting and/or folding the projecting vehicle parts. At least one distance detection or proximity sensor, which is functionally connected to the actuating mechanism, is provided in the vehicle to detect the distance and/or the approach of an object with respect to the respective projecting vehicle part, and the actuating mechanism retracts or folds the respective vehicle part upon a detection signal delivered by the sensor and indicating a collision hazard with the object.

Abstract: A method is described of operating a sliding roof system for a motor vehicle. The sliding roof system includes a sliding roof, a sliding roof drive with a sliding roof motor, a device for controlling the sliding roof drive, and a device for emergency displacement of the sliding roof. Operation of the device for emergency adjustment of the sliding roof is detected, and this information is relayed to the device for controlling the sliding roof drive. Such a sliding roof system is also described.

Abstract: A method and a device for operating a position sensor made of at least two parts that move in relation to one another. The first part of the position sensor has at least two sections magnetized in different directions, and the second part has at least one magnetic field sensor which detects the magnetic field of the first part and converts it into signals having two levels depending on the polarity of the component of the magnetic field in a predefined spatial direction. The levels are supplied to a signal-processing arrangement which evaluates them to determine the relative position of the first part in relation to the second part.

Abstract: An electric motor drive for an automotive operating element for moving between at least two end positions. A range about at least one selected position of the operating element is established. The drive automatically moves the operating element into the selected position when the automotive operating element has reached the established range.

Abstract: An apparatus for operating a positioning drive is proposed, in which a distance between two predefined positions is ascertained in the course of a reference run, and is used as the basis for a data set selection.

Abstract: Suggested are a device and a method for electronically monitoring an adjustment drive arranged in a vehicle, for which a second adjustment drive (17) is actuated by an electronic control unit (12) in dependence on a first adjustment drive (15) in order to ventilate the vehicle inside space. This reduces the risk of a faulty actuation of the closing force limitation as a result of pressure changes.

Abstract: An apparatus and a method are proposed which serve to correct a limit value (16) of the closing force limitation, particularly for a sliding roof. The apparatus and the method comprise an air pressure sensor (14) from whose signals are determined a reference pressure (19) by means of averaging and pressure changes as deviations from this reference pressure. An electronic control unit (12) changes the limit value (16) of the closing force limitation as a function of the pressure conditions.

Abstract: An electric motor drive having a first section and a second section offset with respect to the first section. A control arrangement and an evaluation arrangement are arranged in the first section, and an electric motor and a sensor arrangement are arranged in the second section. The control arrangement is connected to the electric motor via two connecting lines. A signal is transmitted from the sensor arrangement to the evaluation arrangement via a third line. The electric energy for the sensor arrangement is transmitted via at least one of the two connecting lines and via the third line, or only via the two lines. The electric motor drive according to the invention is suitable for use in actuators which may be arranged in a motor vehicle.

Abstract: A device for detecting the movement of a movable component in that the position signals furnished by two position sensors are added to form a signal that is conducted through a line to an evaluation arrangement. The position ranges associated with the position sensors have an overlap region. Different discrete values are assigned to the position signals and can be evaluated easily in the evaluation arrangement.
