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.
