"智能控制的轿车灯光系统设计：提升行车安全性，降低事故发生可能性"

this paper is based on the AT89C51 single-chip microcomputer technology, which can simulate the intelligent control of the car's lights during driving. The system can intelligently control the car's lights in different external environments or conditions. For example, when meeting other cars at night, the intelligent light system of the car can automatically and timely switch between high beam and low beam lights based on the lights of the oncoming vehicles. During daytime driving, if the car enters a tunnel or an underground parking lot with insufficient light, the low beam lights of the car can automatically turn on. Additionally, if encountering heavy rain while driving, the position lights of the car can automatically turn on. The system designed in this paper aims to optimize the traditional lighting system of the car, minimizing the manipulation of lights by the driver as much as possible. This system effectively enhances driving safety, greatly reduces the possibility of accidents, protects the personal safety of the driver and passengers, and also safeguards the property safety of all passengers in the car. Key words: car high and low beam lights; position lights; single-chip microcomputer; intelligent control; safety.
