Abstract -
During the night driving, the reaction time of a human driver go into a compromise due to inadequate peripheral vision or lack of color and depth perception. The conventional headlamps of any automotive vehicle are insufficient to provide an effective illumination in the road while the vehicle is negotiating a curve. The Adaptive Front Light System assists to improve the visibility of the road during the night time driving, which in turn improves safety by reducing the probability of accidents. The Adaptive Front Light System controls the aiming direction and pattern distribution of the low beam according to the amount of steering wheel angle, the vehicle speed and the direction of cornering. This feature is known as low beam “Swiveling”. Additionally, the Adaptive Front Light System is featured with a functionality called low beam “Leveling” which makes the head lamp capable of positioning the low beam exactly in to the intended position irrespective of the weight distribution between the front and rear side of the vehicle. Static weight distribution might happen if the vehicle is loaded with additional passengers or extra luggage in the boot space. Dynamic weight distribution might happen during the acceleration or braking, which introduces a pitching motion to the vehicle over the lateral horizontal axis. Furthermore, the Adaptive Front Light System features the High beam length adjustment in country roads according to the speed of the vehicle which in turn improves the visibility of the road while the vehicle is cruising with a high speed.
