Automatic Headlamp Control and Obstacle Detection

Abstract

The numberof vehicles nowadaysincreasingvery fastly and so is technology. Safety is averyprime factor and has to be considered. vehicles are fitted with lots of safety features. Automatic Upper Dipper beam control and obstacle detection also need to be installed to improve safety to the next level. Thesefeatures are mainly used in nighttime driving or foggy weather or rain. Human eyes are very sensitive to light. when the light suddenly comes in contact with the eyes after darkness, the cornea present in the eyes gets contracted. i.e., human eyes will not be able to see for a short time. it is also called light glare. a vehicle coming from the opposite side with headlight in upper mode causes blind to the driver’s eyes. Insuch cases,there are high chances of occurring an accident. So, an automatic mechanism for controlling the light upper or dipper has to be made todecrease the chances of accidents during nighttime driving. Also, sometimes the driver won’t be able to see any object in nighttime orfoggy or rainy seasons. so, a sensor-based system where obstacle detection is enabled may assist from falling into an event of a crash. these two features assure you a very safe and comfortable drive. The operatingprinciple working and design of PCB is explained in this paper
