Abstract:

In 2003, the first AFS systems have been launched in various vehicles. The movable headlamps should improve the visibility mainly in curved roads. Especially the comparison between the Xenon (HID) - version and the Halogen system was noticed with considerably high interest. The paper describes the experimental study we did in order to find out, what the real benefit on the road for the consumer is going to be. The evaluation shows, that even with the AFS Halogen solution we can report a higher visibility in curved roads than with the static Xenon system. Additionally, the introduction of static bending lights and cornering lights in combination or as a stand alone system will be considered. The subjective impression for a better visibility for the drivers when parking or making U-turns could be clearly detected by the experimental survey. Nevertheless, the dynamic bending lights are getting the highest priority for the drivers at night. The AFS system as the fast track solution will be discussed with the upcoming complete AFS system regulation. The expected additional benefit will be described and discussed. Overall the introduction of the dynamic bending light seems to cover the major advantage of the AFS philosophy.
