Abstract:
A spindle drive for an adjustment element of a motor vehicle is provided. The spindle drive has a drive unit and a spindle-spindle nut transmission arranged downstream of the drive unit in terms of drive for generating linear drive movements. The drive unit has a tubular drive unit housing and therein a drive motor. In some cases an intermediate transmission is arranged downstream of the drive motor in terms of drive. The drive unit and the spindle-spindle nut transmission are arranged one behind the other on the geometrical spindle axis, and a spindle drive housing is provided with a tubular inner housing and a tubular outer housing. The inner housing runs in a telescope-like manner in the outer housing. In some cases the outer housing of the spindle drive housing accommodates the drive unit with the drive unit housing and is connected to the drive unit.

Abstract:
The invention relates to a drive arrangement for the motorized adjustment of an adjustment element of a vehicle, wherein at least one drive comprising an electric drive motor and a drive control means and is connected to a supply, wherein the drive is designed in a non-self-locking manner, the drive motor operates as a generator and generates a generator voltage, wherein the drive control means has a driver unit for supplying electrical power to the at least one drive. The invention proposes that the drive control means has a switching device and has a detection device for detecting a non-motorized adjustment of the adjustment element, and that the drive control means, when a predetermined, non-motorized adjustment of the adjustment element is detected, connects the supply voltage to the supply connections of the driver unit by means of the switching device in one switching operation.

The invention relates to a method for operating a flap arrangement of a motor vehicle, wherein the flap arrangement has a flap wing and a control arrangement, wherein a flap drive which is assigned to the flap wing and by which the flap wing can be adjusted between a closed position and an open position in an adjustment process is provided, wherein at least one predetermined flap operator control event is detected by means of the control arrangement and the flap drive is actuated as a technical control reaction to a flap operator control event. It is proposed that by means of the control arrangement the technical control reaction of stopping or continuing an adjustment process, which is due to two successive flap operator control events, is suppressed if at least one suppression condition is detected.

The invention relates to a method for actuating a closure element arrangement of a motor vehicle, wherein the closure element arrangement comprises a control arrangement and an operator-control-event sensor arrangement with at least one operator-control-event sensor element which is configured, in particular, as a proximity sensor, wherein within the scope of operator-control-event monitoring by means of the control arrangement the sensor measured values of the operator-control-event sensor arrangement are monitored to determine whether a predetermined operator control event is occurring, and the closure element arrangement is actuated as a function of the result of the operator-control-event monitoring. It is proposed that externally activated lifting of the motor vehicle is detected by means of the control arrangement, and the actuability of the closure element arrangement which is due to an operator control event is deactivated when a special condition due to the lifting of the motor vehicle occurs.
Abstract:
The invention relates to a method for controlling a motorized flap, wherein the flap arrangement comprises a flap which may be a pivotable flap, a drive arrangement associated with the flap and a control arrangement associated with the drive arrangement, wherein the deflection of the flap is limited in at least one first direction of movement, by a mechanical end stop on the motor vehicle side, wherein the motorized flap movement in the first direction of movement is limited by means of the control arrangement by an end stop provided by control technology, in order to prevent the flap from running in a motorized manner in the first direction of movement into the mechanical end stop.
Abstract:
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).
Abstract:
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.
Abstract:
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.
Abstract:
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.
