The invention relates to a drive assembly for the motorized adjustment of an adjusting element (1) of a motor vehicle, wherein at least one drive (2) having an electrical drive motor (3), in particular a direct current motor, and a drive controller (5) associated with said drive (2) and connected to a supply (V), in particular a vehicle battery, having a supply voltage Uv are provided, wherein said drive (2) is designed to not be self-locking, such that the drive motor (3) operates as a generator in the event of a non-motorized adjustment of the adjusting element (1) and creates a generator voltage UG, wherein the drive controller (5) has a drive unit (6) for supplying the at least one drive (2) with electric drive power. According to the invention, the drive controller (5) has a switching device (7) for switching the supply voltage (Uv) through to the driver unit (6) and a detecting device (8) for detecting a non-motorized adjustment of the adjusting element (1), and in the event of a predetermined, non-motorized adjustment of the adjusting element (1) being detected, the drive controller (5) switches the supply voltage (Uv) through to the supply terminals (9, 10) of the driver unit (6) in a switching operation by means of the switching device (7), such that the drive motor (3) acts on the supply (V) as a generator and is accordingly braked. |
