Facts and Feelings Regarding Motorway Light in Adaptive Headlamp Systems

On one side, the photometrical performance will be shown in measurements, e.g photometric data and comparison to the existing driving situations with standard headlamps.

The improvements of an AFS motorway function are investigated in visibility/detection distances, reaction distances and braking distance calculation. The results will be presented at the lecture.

A new approach will be the evaluation how the improved light performance is accepted by the driver when driving adaptive lighting systems. It can be assumed that the fact that during night time driving the fixation is mostly oriented in front of the car in illuminated areas, the visible change of light performance will lead to clear statements about acceptance among drivers. For this reason, a questionnaire is currently evaluated in order to find an acceptance rating for the motorway situations. The paper will address both fields of interest and describe the results in terms of traffic safety and comfort acceptance.
