摘要:
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.

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.
摘要:
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.

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.

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.
摘要:
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. Prior to disabling the at least one magnetic field sensor when the first part is at a standstill with respect to the second part, the level delivered by the magnetic field sensor is stored, detected again after the magnetic sensor is enabled again, compared with the stored level, and if the measured level does not coincide with the stored level, the level change is evaluated as a valid level change.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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.
