As technology advances, the traditional lighting system also continues to develop, but in practice, there are still many problems in the traditional headlamp system. Facing complex road conditions and driving conditions, there are colossal security bungles in the traffic safety. Therefore, how to make the traditional automotive lighting intelligent, and how to make the driving more secure and more comfortable have become a very urgent and great practically significant issue. The traditional automotive lighting drive at night may be faced some conditions, for example, inability of adjusting illumination angels at the curve, the appearance of blind section at the clip, inability of adjusting illumination angels at the ramp, based on which, a headlamp adaptive lighting control system at the curve is put forward in order to improve the driving safety at night. This paper introduces a Computer control system of the automotive adaptive headlamps with STC90C51 microcontroller core design. The paper will briefly introduce the background of the appearance of auto-adaptive headlamps, and its current development situations and trends at home and abroad. It will also analyze the composition, function and working theory of the system. The hardware part in the paper detailed designs the host controller and peripheral circuits of the auto adaptive headlamps left and right tuning computer control system. The software part projects the overall process of system software, algorithms program, finishing a control system that can optional turn according to vehicle speed and steering angle signals. The final system debugging ensures
