Abstract

A motor vehicle has a tailgate arrangement consisting of a pivotable lower tailgate and a pivotable upper tailgate, the upper tailgate reaching partially over the lower tailgate in an overlapping region. A sensor system detects the respectively current position of both tailgates in the tailgate arrangement. The sensor system is connected to an electronic control unit for motorized actuation of both tailgates. The control unit has a functional module and in the process prevents a collision of the two tailgates in the overlapping region with consideration of their respectively current positions. The functional module is programmed such that, during closing of both tailgates starting from their respective start positions, their respective moving speed and/or their respective moving start are controlled in such a way that the upper tailgate passes a defined anti-collision position in the closing direction only when the lower tailgate is completely closed. The functional module may be programmed such that, during opening of both tailgates, the lower tailgate is not moved in the opening direction until the upper tailgate has passed the defined anti-collision position in the opening direction. The anti-collision position is a defined point, from which the possibility of geometric superimposition of the pivoting regions just cannot yet exist.
