Abstract

A motor vehicle has a central light control device, a plurality of peripheral light control devices distributed within the vehicle, and a plurality of interior light modules, each of which has a plurality of light sources and is associated with a peripheral light control device.

First claim

What is claimed is:

1. A motor vehicle, comprising:
a central lighting control device;
a plurality of peripheral lighting control devices distributed in the motor vehicle;
a plurality of interior light modules, each of which comprises a plurality of light sources, and each of which is assigned to a respective one of the plurality of peripheral lighting control devices;
a data bus, through which the central lighting control device and the plurality of peripheral lighting control devices are coupled to one another, wherein
the plurality of peripheral lighting control devices each comprise a data memory, in which lighting effect parameter sets are stored, to each of which a lighting effect identifier is assigned, and
the central lighting control device transmits lighting effect identifiers to at least one of the plurality of peripheral lighting control devices in order to initiate motor vehicle interior lighting effects.

2. The motor vehicle as claimed in claim 1 , wherein
in the central lighting control device, different lighting effect identifiers or groups of lighting effect identifiers are assigned to different motor vehicle operating states, and
the central lighting control device is configured such that lighting effect identifiers or groups of lighting effect identifiers are transmitted to the at least one of the plurality of peripheral lighting control devices automatically, depending on a detected motor vehicle operating state.

3. The motor vehicle as claimed in claim 2 , wherein
the central lighting control device is coupled to input devices for input of user preferences, wherein, in the central lighting control device, different lighting effect identifiers or groups of lighting effect identifiers are assigned to different user preferences, and
the central lighting control device is configured such that lighting effect identifiers or groups of lighting effect identifiers are transmitted to the at least one of the plurality of peripheral lighting control devices automatically, depending on a user preference that has been entered.

4. The motor vehicle as claimed in claim 1 , wherein
the central lighting control device is coupled to input devices for input of user preferences, wherein, in the central lighting control device, different lighting effect identifiers or groups of lighting effect identifiers are assigned to different user preferences, and
the central lighting control device is configured such that lighting effect identifiers or groups of lighting effect identifiers are transmitted to the at least one of the plurality of peripheral lighting control devices automatically, depending on a user preference that has been entered.

5. The motor vehicle as claimed in claim 1 , wherein
the activation of the light sources of a light module is defined through a lighting effect parameter set.

6. The motor vehicle as claimed in claim 1 ,
different lighting effect identifiers are assigned to the same lighting effect parameter sets in the respective data memories in different ones of the plurality of peripheral lighting control devices.

7. The motor vehicle as claimed in claim 1 , wherein
the same lighting effect identifiers are assigned to the same lighting effect parameter sets in the respective data memories in different ones of the plurality of peripheral lighting control devices.

8. The motor vehicle as claimed in claim 1 , wherein the parameter sets stored in the data memory of each of the plurality of peripheral lighting control devices comprises information about light color, light duration, light intensity, delay time, activation time point, deactivation time point and/or light intensity curve.

9. The motor vehicle as claimed in claim 8 , wherein after receipt of the lighting effect identifiers transmitted by the central lighting control device, the at least one of the peripheral lighting control devices maps the received lighting effect identifiers onto an assigned lighting effect parameter set stored in the data memory of a respective one of the at least one of the peripheral lighting control devices.

10. The motor vehicle as claimed in claim 9 , wherein the at least one of the peripheral lighting control devices activate at least one of the plurality of light sources of a respective one of the plurality of interior light modules to which the at least one of the peripheral lighting control devices are assigned based on the assigned lighting effect parameter set stored in the data memory at least one of the peripheral lighting control devices.
