Smart control of headlight intensity of automobiles for improved night vision

Abstract

In the early days of automobiles, speeds of vehicles were very low and there were relatively few vehicles on the road. The increase in the number of vehicles and their speed has already outpaced the improvements on roads and the other traffic facilities, resulting in unsafe road travel. The fundamental component of night driving is the headlight which provides better vision. On the other the hand vision of the driver is affected by the headlights of oncoming vehicles. Moreover, the traffic moves at a faster rate at night, this leads to head-on collisions. Night driving is a phenomenon governed by a number of factors. So to provide optimal illumination at all distances when vehicles are in the vicinity, a controller is designed such that speed, distance of a vehicle from another vehicle, driver action, weather condition, type of road (terrain, bend, highway) while driving are taken into account to generate the effective output intensity free of glare. Since the inputs are fuzzy in nature, a fuzzy controller is designed.
