Active Safety Performance Generated with Adaptive Lighting Systems

Adaptive Lighting systems generate different lighting patterns according to the environmental situation that is evaluated by electronic control units. On one side, the photometrical performance will be shown in measurements, e.g. photometric data and visibility/detection distances, reaction distances and braking distance calculation. A second 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 different driving situations. The paper will address both fields of interest and describe the results in terms of traffic safety and comfort acceptance.
