Method for generating a warning signal to switch on the lighting system of a vehicle and devices for use with said method
First Claim
1. A method for producing a warning signal for switching on a vehicle lighting system when the environmental brightness is inadequate on the basis of an external light signal, wherein, in a first step, transmitting the external light signal as a radio signal, receiving the signal by the vehicle and detecting operating data of the vehicle, wherein subsequently, evaluating the data by means of a control unit on board the vehicle and, producing a warning signal for information of the operator;
- wherein the control unit detects said radio signal with data relating to the environmental brightness and detects a switching state of the vehicle lighting system;
wherein the control unit receives signals of a navigation device and determines geographical position from the navigation-device signals, and matches the position to a road map for production of a warning signal if the vehicle is located in a region in which there is a necessity or a requirement to drive with the lighting system switched on even if the environmental brightness is adequate; and
the control unit produces a warning signal if the vehicle lighting system is switched off and the environmental brightness is inadequate even if the geographical position from the navigation-device signals does not match the road-map position, the control unit logically linking switching states for production of the warning signal based on environmental brightness and geographic constraints.

Abstract
In a method for producing a warning signal for switching on a vehicle lighting system when the environmental brightness is inadequate, the external light signal is transmitted as a radio signal, in a first step, and is received by the vehicle. In addition, further operating data are detected, an evaluation is then carried out by a control unit and, if necessary, a warning signal is produced for the operator. In an apparatus for use with the method there is control unit for detection and logic-processing of signals. This control unit produces a warning signal for the driver.
