With the rapid development of the automotive industry and the increasing demand for road traffic safety, the automotive lighting system has evolved from a simple lighting tool into a key component for ensuring driving safety. Therefore, this paper conducts research on an intelligent automotive lighting control system based on a single-chip microcomputer, aiming to design a solution that is both practical and economical. The system uses the STC89C52 single-chip microcomputer as the control core, perceives ambient light intensity, the distance of obstacles ahead, and the vehicle's steering state through multi-sensor fusion, realizes adaptive adjustment of lights in combination with intelligent control algorithms, and improves the system's stability in the complex electromagnetic environment of automobiles through hardware optimization and software anti-interference design.
