The present invention relates to a method for protection against jamming in a motor-driven locking system and a device for the execution of the method.

Method and device for protection against jamming in a motor-driven locking system

In the method of controlling a process for moving a part () by an electric motor () against an end stop, pinching events are detected by monitoring a motor operating variable, such as a motor rpm, and if pinching is detected the motor () is stopped and/or reversed. The electric power triggering the motor () at the start of and during a startup phase while system slack is taken up is controlled so that it is constant and lower than the power triggering the motor in an ensuing operating phase () in which the part () moves. Preferably power during the startup phase is reduced to power values that are just barely enough to move the motor while system slack is taken up. In a preferred embodiment the applied motor voltage is reduced and controlled by a power end stage that includes a bipolar transistor or a field effect transistor.

Method for controlling an adjustment process of a part

A method of bridging partial tightnesses of moveable members received in guides and driven by electric drive motors provides an automatic monitoring function. Within a tightness region, a releasing force is varied in one or several steps. An automatic bridging function is utilized, which corresponds to the rotary speed course, and an automatically operating control operates so that the releasing force is increased only in a limited region of the identified bridging location.

Method for electronic surveillance and control of the opening and closing procedure for electrically operated units

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.

Method and apparatus of controlling a sliding roof

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 ( ) is integrated in an integration stage ( ) and supplied to a comparator stage ( ). The total light quantity formed by the light of a transmitter ( ) and extraneous light and the extraneous light quantity detected when the transmitter ( ) is switched off are measured in separate time intervals (Tg, Tf, Tf&prime;). The time interval (Tf, Tf&prime;) 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 (S ) is to be lowered for day-night detection.

Device for detecting surface wetness

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.

Method for positioning a part

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 (,) of the sliding and lifting sunroof from its raised position to its closed position, and which detects a situation of wedging of an object (,) wedged between the cover (,) and the opening of the sliding and lifting sunroof with the help of a sensor (,). Furthermore, for detecting a situation of wedging, provision is made for a water duct (,), which is movably arranged on the roof (,) of the motor vehicle within the opening of the sliding and lifting sunroof.

Method and apparatus for triggering a sliding and hinged sun roof

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.

Device and process for electronic monitoring of an adjusting drive in a vehicle

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.

Sliding roof system and method of operating same

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.

Method and device for operating a position sensor

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.

Electric motor drive

The adjusting device for adjusting a position of a sun roof of a vehicle has one incremental position encoder and two absolute position encoders, with whose aid, at each position of the sun roof, an unambiguous association with the actual position of the sun roof is possible, regardless of whether there has been a failure of the adjusting device or a mechanical change in position of the sun roof. The adjusting device of the invention is intended for a sun roof of a motor vehicle.
