Abstract
Disclosed herein is a drive arrangement for motor-operated adjustment of a closure element in a motor vehicle having at least one drive with a drive motor, and a drive controller. The closure element can be driven in the motor-operated adjustment mode by the drive motor in the closing direction and in the opening direction between a closed and an open position. The drive is non-self-locking and has a sensor, in particular a Hall sensor, for sensing the drive movement. The drive controller monitors the sensor signals for a fault state, and when a fault state is sensed initiates an emergency braking and/or stop mode. The drive arrangement comprises two drives each with a sensor for determining the respective drive movement. To detect drive-fault-induced slamming shut of the closure element, the drive controller correlates the sensor signals of the two sensors, in particular compares said sensor signals.
