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 (S1, S2) to a lighting device, which receives the control signals from a transmission module (SM), is implemented in dual-track fashion throughout. This provides the corresponding redundancy and increases the required reliability. It is advantageous, in particular, to transmit to the lighting device a control signal (EIN) and a correspondingly negated signal (formula (I)), so that the lighting device is able to check whether the data processing and data transmission were free of faults.

13. 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. - View Dependent Claims (14, 15, 16, 17, 18)
