Adjusting device

Adjusting device for a vehicle part which is movable relative to a body of a vehicle, in particular a vehicle door or a vehicle tailgate, comprising:

• a drive arrangement
• having a drive unit and
• at least one movement state sensor for detecting a movement state of the drive unit and for outputting corresponding movement state signals,
• an adjusting element, which is displaceable relative to the drive arrangement via the drive unit, and
• a control unit, associated with the drive arrangement, for activating and deactivating the drive unit,
• wherein the control unit has a signal input to which the at least one movement state sensor is connected for transmitting the movement state signals to the control unit, and in that the control unit is configured to actuate the drive unit according to the actual movement state if the movement state signals transmitted to the control unit by the movement state sensor indicate an actual movement state of the drive unit which deviates from a target movement state,
• wherein the control unit is further configured to distinguish a movement pattern of a manual actuation of the vehicle part which is movable relative to the body of the vehicle from a movement pattern of a gravity-induced actuation of the vehicle part which is movable relative to the body of the vehicle, wherein as a distinguishing criterion an acceleration is used, with which the vehicle part which is movable relative to the body of the vehicle is set in motion, and
• wherein the control unit is further configured to only actuate the drive unit according to the actual movement state if a movement pattern of the actual movement state fulfils at least one predetermined condition with regard to the acceleration, which indicates the manual actuation of the vehicle part which is movable relative to the body of the vehicle.
