METHOD AND DEVICE FOR CONTROLLING THE LIGHT FUNCTIONS IN FRONT HEADLAMPS FOR ROAD VEHICLES
First Claim
1. A method for controlling the light functions in front headlamps for road vehicles,wherein a dipped headlight and a full beam, which each comprise one or more light functions, are provided,wherein in order to select a light function one or more variable actuators of the front headlamps are set to a predetermined fixed position,wherein the selection of a light function with a beam width in the region between the dipped headlight and the full beam is not possible,and wherein there is no means of locking the at least one actuator in the intermediate region of the position of the at least one actuator for the dipped headlight and the position for the full beam.

Abstract
Future vehicle headlamps will provide light functions, such as, for example, town light, country road light, motorway light, full beam, poor weather light, etc. A method and a device is therefore provided with which the light functions of vehicle headlamps are controlled in a reliable manner. The device essentially comprises front headlamps with a dipped headlight and full beam, and at least one variable actuator with which different light functions can be realized. In order to select a light function, the variable actuator is set to a predetermined, fixed position. In this case, it is not possible to select a light function in the region between the dipped headlight and the full beam, there being no means of locking the actuator in the intermediate region between the position of the actuator for the dipped headlight and the position for full beam. Only a light function which is matched to the driving situation and can be selected in a reliable manner is therefore possible.
