Abstract—Segmentedhigh beam functions, which are controlled by camera signals during nighttime,are under development and just starting on the market. They are able to providethe so called “glare free high beam” by switching on automatically segments ofthe high beam also during the presence of other traffic participants ahead ofthe own car. On a standard test track under real traffic conditions, differentsegmented high beam solutions have been tested and the advantage for thedrivers is statistically evaluated: Ifthe segments of the high beam can be switched on depends on different parameters:The width of the segments, the control algorithm, etc.
In addition tothese statistical data, a key factor is the perception of the driver. How doesan average driver judge different segmented high beam systems?
Thereforeselected segmented high beam configurations were obtained by a prototype headlampsystem and presented to drivers during field tests under real trafficconditions. The test drivers evaluated these segmented high beam sets due totheir safety and comfort impression. Severalquestions concerning efficient segmented high beam solutions will be addressedby this investigation: 1. How often is which segment illuminated? 2. Which segments are activated most? 3. What is the experience for the driver ifthe amount of segments is reduced? 4. Is the optimum segment size depending onthe horizontal position? Theanalysis of the driving test according to this questions will also be presentedin this presentation.
