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.

Drive arrangement the motor-operated adjustment of an adjusting element in a motor vehicle

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.

Method for operating a flap arrangement of a motor vehicle

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.

Method for controlling a motorized flap arrangement of a motor vehicle

Described herein is a method for operating a hatch arrangement of a motor vehicle wherein a motor vehicle lock is controlled by means of a control arrangement in a relatch routine in such a way that a renewed latch state (a relatch state) is avoided or cancelled within a predetermined relatch time interval after the releasing process, and wherein in a relatch monitoring process the control arrangement monitors whether a relatch indication, in particular a relatch state, occurs within the predetermined relatch time interval after the releasing process and only then is the relatch routine triggered.

Method for operating a hatch arrangement of a motor vehicle

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.
