Abstract:
A drive assembly for driving a moveable component of a vehicle, which component can adopt a position in which the component prevents access to a part of the vehicle, the drive assembly comprising an actuator, which is coupled to the component and can provide a force f or moving the component, and a control unit for controlling the actuator, the drive assembly having an emergency operating mode, in which the actuator can move freely in at least one direction, and allows thereby a movement of the component caused by an external force being exerted on the component other than by the actuator, the drive assembly further being provided with a theft detection unit for detecting theft or attempted theft of the vehicle or of goods which are present in the vehicle, and the theft detection unit being coupled to the control unit, whereinthe drive assembly is designed such that, if the drive assembly is in the emergency operating mode and the moveable component is in a position in which the component prevents access to a part of the vehicle, and then the theft detection unit detects theft or attempted theft, the emergency operating mode of the drive assembly is cancelled, and the drive assembly is then brought into a blocking mode, in which the actuator blocks any movement of the component caused by an external force being exerted on the component.
