Design and implementation of intelligent headlamps control system based on CAN bus

Traditional headlamps can not adjust the angle and range of the light irradiation on a curved road at night, so potential security threat exists for driver. This paper comes up with a corresponding solution to the problem, and designs a headlamp control system. Differences between traditional headlights and Adaptive Front Lighting System are introduced firstly. Then, the motion models of headlights are establish, and turn angle of the headlamps in horizontal direction and vertical direction can be calculated by mathematical equations. The holistic design of the system is put forward. And hardware circuit and software of the intelligent headlamp control system is designed. Control algorithm uses the fuzzy control, and fuzzy controllers are designed. Finally, many experiments have been done and the results indicates that the design proposal is feasible and the control system has good dynamic characteristic.
