Abstract
Described herein is a drive arrangement for the motor-driven adjustment of an adjustable element in a motor vehicle, the drive arrangement having two electrical drives and a control device, the drives, in the fitted state, acting in the same way on the adjustable element and having a substantially identical configuration, apart from tolerance-related discrepancies. The control device has a power controller which, in the fitted state, during the motor-driven adjustment of the adjustable element, subjects the electrical power that is output respectively to the two drives to closed-loop control, for the purpose of compensating for the tolerance-related discrepancies, in such a way that an identical electrical power consumption is established for both drives.
