AFS design on FPGA for automobiles

AFS system or Automatic front light system is an add-on feature in the modern vehicles which improved the safety of vehicle drivers and passengers travelling at night by providing intelligent illumination thus reducing driver fatigue. FPGA is considered as a boon for the design engineers and is better considered now in many military applications because of its sustainability and efficiency to work in harsh environments. In this paper we have designed an AFS system on FPGA keeping the conventional light pattern to improve illumination at night and the safety of the users. This system uses DPWM technique with high resolution which provides us with better control over beam patterns and intensity of the headlamps.
