The invention relates to a device for centrally controlling the passenger compartment lighting of a motor vehicle. The inventive device comprises a central control unit (1), at least one control device (2-10) and at least one lighting unit (12-18), whereby at least one lighting unit (12-18) is assigned to the at least one control device (1-9), and this lighting unit (12-18) can be controlled by the control device (1-9). The aim of the invention is to reduce to a minimum the number of cables to be installed and, nevertheless, providing a comfortable passenger compartment lighting control. To these ends, the invention provides that the central control unit (1) and the at least one control device (2-10) can be connected to a common data line (11), and a state of a vehicle element can be interrogated by the at least one control device (2-10) that is assigned to a vehicle element, whereby state information of the vehicle element can be transmitted via the data line (11) to the central control unit (1), and whereby control information can be transmitted from the central control unit (1) to the control device (2-10) via the data line (11) in such a way that the passenger compartment lighting can be controlled according to the state parameters of the vehicle elements. |
