Abstract: A method for controlling an electric drive motor (10) of a motor vehicle adjusting drive by means of applying a variable voltage to it should be improved so that an EMV interference suppression can be inexpensively executed. To this end, a controllable resistor (12, 18, 20, 22) is used, which supplies the voltage applied to the drive motor (10).

Abstract: In order to reduce assembly cost for attaching the electronic module and to realize better protection of the circuit board in an electronic module for an electric motor operated drive unit, in particular, for an electric motor operated automobile window opener, including an electronic housing part, which can be attached to the housing of the drive unit, with a connector piece arranged thereon and a circuit board inserted in a mounting means the electronic housing part and having electric and/or electronic components, which circuit board is electrically connected to contact elements of the connector piece and to power leads fastened to the electronic housing part, with the power leads being provided with contact sections projecting from the electronic housing part, it is suggested that the electronic housing part be configured as a separate housing which has a housing interior which can be closed with a cover; that the circuit board be arranged completely in the housing interior; and that a second connector pi

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: 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: 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.

Abstract: An arrangement for operating an adjustment drive (11) comprising a relay-controlled change-over facility (12) for the right-handed rotation/left-handed rotation of the positioning motor (10). A first semiconductor switch (23) is provided to supply current to a first relay winding (15) and a second semiconductor switch (25) to supply current to a second relay winding (16). A third semiconductor switch (26) is connected in series with the first relay winding (15) and in series with the second relay winding (16). By turning the third semiconductor switch (26) on and off, it is possible to enable or block a supply of current to the relay windings (15, 16). An alloying through of one of the first two semiconductor switches (23, 25) remains without consequences for the adjustment drive (11). An inadvertent adjustment process does not occur.

Abstract: A method for operating a microprocessor (10) which can be switched by an activation signal (23) at an interrupt input (15) from an inactive operating state to an active operating state, with the activation signal (23) being supplied to the interrupt input (15) after a predeterminable time after each entrance into the inactive state.
