Today dynamic bending light and other adaptive lighting functions as town-, country-, motorway- or adverse weather lighting are introduced in a lot of series headlamp projects. Now camera sensors enter the market, which are positioned in the passenger compartment behind the windshield near the rear view mirror. These sensors will enable the next step of improvement for drivers safety and comfort for the future, if they will be supported by new optical systems in the headlamp to provide new camera controlled lighting functions. The second generation of AFS projection systems as e.g. the AFX system from Automotive Lighting are able to provide not only the AFS adaptive low beam lighting functions, but also the adaptive cut-off and adaptive partial high beam light distributions, which are controlled by a camera sensor in the car. Taking other traffic participants into account by controlling the light distribution it could be shown by statistical evaluation of nighttime driving tests, that the frequency of using high beam or adaptive partial high beam on country roads and motorways in average is larger than 30% and up to 70% even during a traffic density of 2 cars / km. This promises a significant improvement of traffic safety during nighttime driving under the consumption that the whole system including the signal information from the camera system is on a high level of reliability.
