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.

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:
In the method of controlling a process for moving a part (20) by an electric motor (12) 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 (12) is stopped and/or reversed. The electric power triggering the motor (12) 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 (54) in which the part (20) 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.

A method for limiting the closing force of movable components (16), in particular windows and sliding roofs in vehicles is provided. The windows and roofs are powered by an electric motor driven servo drive. The inventive method comprises at least the following steps: determination of the actual motor rotation speed n by evaluating periodic signals from a sensor connected to a servo drive; calculation of a typical parameter on which reflects a change in motor rotation speed; summation and saving of an actual typical parameter in a sum storage device; starting of a timing device and a threshold sensor, in the event that the summed parameter value totals exceed a parameter threshold value; comparison of an actual threshold value g(t) with an actual, summed parameter value; triggering of a mechanism to limit the closing force and resetting of the timing device and the summed value storage device, if the respective current value of the summed parameters are the same as or equal to or larger than the respective current threshold value g(t); termination of the comparing procedure and resetting of the timing device in addition to the summed value memory, if the respective value of the summed parameter is smaller than the respective current threshold value and is within a predefined tolerance and additionally, a predefined time unit remains constant.
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.
摘要:
A method of controlling the rpm of a motor by employing an incremental indicator or sensor (rpm), in which motor control with a reduced starting torque and a reduced startup short-circuit current is intended to be attained in a simple manner. For this purpose a control signal guided to a power output stage that actuates the motor is pulse-width modulated.

The invention relates to an electromotive drive (1) for a motor vehicle actuating part (2) which can be moved into at least one defined target position (16), said drive having a detection device (14) for detecting whether the motor vehicle actuating part (2) is in a tolerance range (19). The invention provides for the tolerance range (19) to be able to be determined on the basis of the stop position (18) of the motor vehicle actuating part (2).
摘要:
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.
