Cornering Lamps and Static Bend Lighting - Performance Aspects and Technical Comparison in AFS-Systems

This paper describes how one of the most important features of a headlamp with adaptive light distribution is the improved side illumination for driving situations in towns, at intersections and in small radius curves. Pending legal requirements will allow the use of bending light realized by side illumination from either a part of the low beam or a separate cornering lamp. The first part of this paper compares the legal requirements of both SAE and ECE regulations for bend lighting and cornering lamps. The second part discusses the performance of different lamps developed on the basis of these regulations and they are compared with respect of technical and performance aspects.

Overview of electrical and electronic systems in the vehicle

The amount of electronics in the vehicle has risen dramatically in recent years and is set to increase yet further in the future. Technical developments in semiconductor technology support ever more complex functions with the increasing integration density. The functionality of electronic systems in motor vehicles has now surpassed even the capabilities of the Apollo 11 space module that orbited the Moon in 1969.
