针对国内汽车前照灯随动系统方面以理论研究为主而缺少工程应用开发的问题，对汽车前照灯水平随动系统的控制策略进行研究。建立数学模型，提出基于安全视距的角度算法，结合法规标准对角度算法进行条件限制，并通过PD算法对角度进行闭环控制，最后依控制策略制作系统样机并进行算法仿真试验和实车模拟试验。试验结果表明，该控制策略满足系统对实时性和误差的要求，并满足AFS法规的要求。

In China, the automakers mainly focus on theoretical research in automotive AFS follow-up system, which lacks engineering application development. To solve this problem, this paper studies control strategy of the automotive AFS follow-up system. We build a mathematical model, and present angle algorithm based on the safety sight distance, and combine with regulations and standards to restrict angle algorithm conditions, and use PD algorithm to close-loop control angle. Finally we build a system prototype in accordance with this control strategy for algorithm simulation test and vehicle simulation test. Test results show that this control strategy meets real-time and error requirement of this system, and satisfies requirement of AFS regulations.
