Glare-Free High-Beam Control for Oncoming Vehicle Safety in Nighttime

Abstract

Improper use of high beams can cause glare interference to oncoming drivers or pedestrian. In this article, an adaptive high-beam controlling system is designed to avoid glare interference. The adaptive high beams are illuminated by group light-emitting diode (LED) particles as the light source. The luminous intensity distribution of single LED particle is determined along with the lighting zones of group LED particles. The oncoming and same direction vehicles are detected by positioning their headlights and tail lights via the received images from the on-board camera. The detected vehicles are mapped to the corresponding LED illumination zones. The adaptive high-beam controlling system turns OFF the LED particles in corresponding with vehicle areas and keeps the remaining LED particles ON. The novelty of our work is that an adaptive high-beam controlling system is developed under the integration of controlled LED particles, an image processor, and a lamp controller. The benefit of proposed adaptive high beams is to avoid glare interference for improving night driving safety.
