Actual studies show that 40 % of all accidents occur at night, but the part of the drives during the night represent only
20 % of all drives . So the risk potential to be involved in an accident at night is almost three times higher in
comparison to daytime.
A headlamp is primary used to illuminate the road. Secondary the signal aspect is an identifying feature for other road
users. As simple as these tasks seem to be, it is not easy to perform it in every situation because of environmental factors.
Especially the weather conditions, but also the type of road and the traffic density causes difficulties. The ambition of the
design of a headlamp is an adaptive system which is able to adjust on various factors to perform these tasks.
In many cases there are already technical possibilities to realise new adaptive concepts, but up to now only a few cars are
equipped with these technology. An example is the levelling system. Every modern car has a manually static or an
automatically static levelling system. But because of the vehicle dynamics and the vertical road geometry it would be
advisable to integrate an automatically dynamic levelling system. This System is currently used in the cars of the upper
class. It would increase the road safety if this technology would be integrated in every car.
This study describes the requirements for modern headlamps, discusses already existing systems and shows the technical
possibilities to realise new concepts.
