1. A control device for a lighting device of a vehicle, comprising:
- at least two sensor devices configured to record control information during output of a first sensor signal and a second sensor signal;
an evaluation device configured to generate a first control signal for the lighting device on the basis of the first sensor signal and the second sensor signal and a second control signal for the lighting device on the basis of the first sensor signal and the second sensor signal; and
a transmission device configured to transmit the first control signal to the lighting device and to transmit the second control signal to the lighting device as a control signal that is redundant with respect to the first control signal.

Abstract
The automated switching of a vehicle lighting system is to be made more reliable. To this end, it is provided that the entire data flow from the sensors to a lighting device, which receives the control signals from a transmission module, is implemented in dual-track fashion throughout. This provides the corresponding redundancy and increases the required reliability. It is provided, in particular, to transmit to the lighting device a control signal and a correspondingly negated signal, so that the lighting device is able to check whether the data processing and data transmission are free of faults.
