Conclusive Review on Adaptive Headlight System for Four-Wheeler Frontlight using Stepper Motor

Abstract

Major road mishaps occur at night on account of curve roads and glare caused from the headlights of incoming vehicles. Night time driving with conventional headlamps is particularly unsafe: only 25% of the driving is done at night but 55% of the driving accidents occur during this period.  The existing conventional light system does not provide illumination in the right direction and at the precise angle. Due to this constrain, a need to understand an alternative technology solution.  Adaptive front lighting system (AFS) helps improve driver’s visibility at night time hence achieving enhance safety. The objective of this work is to design and build an AFS Prototype. From the results, it is concluded that the headlamp swings in horizontal direction by sensing steering angle and vertical by sensing distance between subject vehicle and next vehicle.  Accuracy, reliability and availability of the components were few considerations during the conceptualization stage.
