Street illuminance level analysis towards responsive headlight automation

Abstract

The vehicles' illuminations level in the road in the night is uncontrolled and beyond the bearable level these days. There are two different beam modes in vehicles, such as dim and high. The high beam mode makes additional illuminance to see through the road far distances in remote areas where the least traffic and pedestrians. The additional horizontal light beams of an approaching vehicle in an urban area with high traffic may cause temporary blindness of drivers and pedestrians. Therefore, the higher beams must be switched to dim mode within a certain distance of a pedestrian or an approaching vehicle. Usually, it is difficult to switch time to time manually in between those modes in reality. Therefore, this study investigates horizontal light illuminance and analyses to make an automated beam control module to be incorporated in the vehicle.
