The invention relates to a control device for carrying out an operating method for an electric window lifter for moving a rear pane (3) in a motor vehicle, in which the rear pane (3) is moved in a lowering direction (−z) along an approximately s-shaped path of movement. In the case of trapping, the movement of the rear pane (3) in the lowering direction (−z) is stopped and the rear pane (3) is moved in the lifting direction (+z).

An adjustable mechanism for a motor vehicle is used to adjust an adjustable element in a motor vehicle, especially a seating part. Said mechanism comprises a spindle nut comprising an axis, said spindle nut co-operating with a thread spindle and comprising external toothing on the external surface thereof which is in contact with an additional drive element. The external toothing of the spindle nut is formed by recesses in the external surface of the spindle nut which are inwardly turned in a radial manner, the teeth depths thereof diminishing in the direction of at least one axial end of the spindle nut.

A method and a control device operate a three-phase brushless direct current motor with phase windings that are fed by an inverter connected to a voltage source having a high potential and a low potential. The semiconductor switches of the inverter are arranged in a bridge circuit and are controlled such that current always flows through two phase windings during motor operation. The motor is operated with normal commutation when the rotational speed is greater than or equal to a minimum rotational speed, wherein the angles are shifted by 60°. During start-up operation, up to the minimum rotational speed, a high-potential-side commutation angle of a phase winding is shifted toward a low-potential-side commutation angle of the phase winding by an angle greater than 0° and less than or equal to 60° with respect to the normal commutation.

A carrier for connection of a window pane to a window lift of a motor vehicle comprises guiding claws spaced apart from each other in a longitudinal direction of a guide rail of the window lift for guiding the carrier on the guide rail. The carrier includes a window pane holder for connecting the window pane with the carrier and an adjusting device for adjusting the position and/or orientation of the window pane with respect to the guide rail. To ensure an exact bearing of the window pane on an associated sealing contour on a motor vehicle body with simple constructive means, little mounting effort and few components, at least one guiding claw is adjustable in a direction vertical to the longitudinal extension of the guide rail or in longitudinal extension of the guide rail and vertical to the longitudinal extension of the guide rail.

The invention in certain embodiments relates to a control circuit for an electric-motor-operated window lifter (10) of a motor vehicle (1), the control circuit having a first switch (11) for opening a vehicle window (7), a second switch (12) for closing the vehicle window (7), and a control device (15), which, when one of the switches (11, 12) is activated, actuates the window lifter (10) to move the vehicle window (7) in the opening direction or closing direction. The control device (15) monitors the lighting current (ILED) which flows across a lighting element (14) for the switches (11, 12), and generates a control signal (I12), if appropriate, for opening the vehicle window (7) if the lighting current (ILED) exceeds an overcurrent threshold value (IRef) thereby detecting inundation of the vehicle.

The invention relates to a drive arrangement for the motor-operated adjustment of an adjusting element in a motor vehicle, wherein the drive arrangement comprises two electrical drives having in each case a drive motor and a control device, wherein in the assembled state the drives act in the same manner on the adjusting element and are embodied in an essentially identical manner apart from deviations that are a result of tolerances, wherein the control device influences the two drive motors by a pulse width modulation voltage (“PWM” voltage). It is proposed that the control device influences the two drive motors by PWM voltages having PWM switching frequencies that vary continuously during the adjustment process in such a manner that the PWM switching frequencies that are allocated to the two drive motors are different from each other at least for periods of time.

The invention relates to a drive arrangement for the motorized adjustment of a flap arrangement for a motor vehicle, with a drive controller for producing a desired flap adjustment by means of at least one drive, wherein the flap arrangement is configured with two flap wings, wherein the two flap wings are each substantially pivotable about a respective spaced-apart, parallel pivot axis and, in the closed state, are in engagement with each other via a respective free wing end opposite the respective pivot axis. The two flap wings are assigned collision pivoting regions which are mounted upstream of the respective closed position and in which the movement regions of the flap wings overlap in such a manner that a predetermined opening and closing sequence has to be observed there in order to avoid collisions between the free wing ends.

A method for operating a hatch arrangement of a motor vehicle is provided. The hatch arrangement has a hatch leaf with a hatch drive associated with the hatch leaf, and a hatch controller, with, amongst other things, a motor-operated closing process triggered by the hatch controller. The hatch arrangement has a motor vehicle lock, it being possible to reverse the hatch leaf starting from an opening and/or closing process in a motor-operated reversing process in a manner triggered by the hatch controller. As part of a reversing process which is initiated starting from a closing process, the motor vehicle lock and possibly the hatch drive is or are actuated, at least in phases as a function of the lock state, in such a way that engagement in a retaining manner between the motor vehicle lock and the lock striker or the like is avoided or released during the reversing operation.

A stator for a motor contains a number of stator sheets stacked in a star-shaped laminated core. The stator sheets contain stator sheets closed in the circumferential direction and have single teeth connected to one another by pole shoe webs and stator sheets open in the circumferential direction and have single teeth spaced apart from one another to form a gap. A bottom starting block is adjoined by a repeat block which has N identical repeat sequences. Each repeat sequence contains n directly consecutive open stator sheets with a gap on the pole shoe side and at least one closed stator sheet. The laminated core also has a terminating block and an intermediate block between the repeat block and the terminating block. The intermediate block contains a closed stator sheet and/or a gap on the pole shoe side created by m open stator sheets, where 1≦m≦n−1.
摘要:
To reduce stresses during closing of a manually closable body component, e.g. a door, a control device and a method of controlling closing movement in which, during the closing movement, from an opened position, the body component passes through first movement range in which the body component is moved towards the closed position without any action by a control member, and, thereafter, the body component passes through a second movement range in which the closing movement is varied by the action of the control member that residual kinetic energy of the body component does not exceed a predetermined limit value after passing through the second movement range, irrespective of the initial speed. The residual kinetic energy is not sufficient to close the body component automatically, so it is automatically drawn in a third movement range until a pre catch or main catch of a lock is reached.
