    摘要： A device for checking the evaluation circuit for automatic switching operations of the illumination devices in vehicles. A sensor device contains a global sensor for detecting the light conditions in the environment of the vehicle and a directional sensor for the directed detection of the light conditions in the direction of travel in front of the vehicle. The signals of the sensor device are supplied to the evaluation circuit, to determine whether a change in the switching state of the illumination devices is necessary. In order to check the evaluation circuit which is designed using analog technology, in the operating state, the voltage supply to the sensor unit is briefly interrupted at predetermined intervals, as a result of which the condition “night” is simulated. When the evaluation circuit is functioning correctly, this is detected by it as such. When the evaluation circuit is not functioning correctly, a signal is generated, directing attention to the faulty functioning and causing further steps to be initiated. In an embodiment, the checking operation and the voltage interruption are carried out by a microcontroller. In a second checking operation, it is established, in particular in the software, whether the emitted signal values of the evaluation circuit do not exceed a lower value that is determined by the hardware. In a third checking operation, the correct functioning of the A/D converter unit is ascertained.

    摘要： A sensor device, by which the light intensity in the surroundings of the vehicle is detected and which is connected to an evaluation device, by which the signals (S) of the sensor device for the light intensity are compared with at least one threshold value, and from that it is ascertained whether a change in the switching state of the lighting devices is necessary. The evaluation device evaluates signals (S) of the sensor device for the presence of at least one periodically variable signal component (Sk), and in the presence of such a signal component (Sk), the lighting devices are either turned on at a certain level, or remain turned on at that level. By this evaluation, light originating from artificial light sources and having a variable intensity depending on the alternating voltage with which these sources are operated, are detected and assure that the lighting devices will be turned on or will remain turned on if the vehicle is driving in a tunnel or underground garage, for instance, where lighting is provided by artificial light sources.
