Abstract

The visual range when driving a car with dipped beam is limited by the statutory beam pattern of the headlamp, and is often not sufficient. Given today’s traffic volume, the main beam can only rarely be used. Active Night Vision systems based on infrared (IR) lighting provide an opportunity to increase the visual range without dazzling oncoming traffic. The systems consist of an IR headlamp, a suitable camera and a man-machine interface (display). In the following, the system concept will be presented and the possibilities of infrared lighting and its integration into modern headlamps will be discussed.
