Abstract

A method for extending the functionalities of a motor vehicle (10) is provided, wherein the motor vehicle (10) has several controllable operating devices, at least one control unit (20) for controlling the respective assigned at least one operating device, and a sub-carrier (18), wherein the sub-carrier (18) has a frame (22) for mechanically mounting the at least one control unit (20) and a common insertion area (24) bounded by the frame (22) for inserting several control units (20) for mounting with the frame (22), wherein the at least one control unit (20) is installed in the sub-carrier (18) such that installation space is provided in the insertion area (24) for at least one further new control unit (28) of the same size.in which at least one previously installed control unit (20) is removed and replaced by a new control unit (28) to provide at least one additional function, and the new control unit (28) has a greater height within the insertion area (24) compared to the previously installed control unit (20). The flexible installation space provided in the vertical direction of the subrack (18) for control units (20, 28) of different sizes allows for easy subsequent expansion of the functionalities of a motor vehicle (10).
