摘要：为了实现前照灯系统能够自动根据车辆行驶状态灵活调整光轴位置和光照形式，结合车辆行驶特点，以国标GB7454-1987和CAN2.0通讯协议为设计准则，综合采用了控制器局域网（CAN）总线技术、传感器技术、控制技术，完成了自适应前照灯系统硬件及软件设计，并进行了实验室CAN/LIN台架试验和实车试验。台架试验表明，该系统的测试精度满足国标规定的使用要求，实车试验也表明，装配有自适应前照灯系统比未装配自适应前照灯系统的光照区域范围更加合理，极大地提高了行车安全性。

Abstract: Aiming at that beam axle position and illuminating form can be automatically adjusted through the front lighting system according to vehicle traveling state, combined with characteristic of vehicle traveling, GB7454-1987 and CAN2.0 protocol were taken as design standard, software and hardware of adaptive frontlighting system(AFS) were designed with integrated application of controller area network (CAN) bus technology, sensor technology and control technology, the system was tested by means of CAN/LIN bench test in the laboratory and real vehicle test. Bench test results indicate that precision of system meet the prescribes of national standard. Real vehicle results indicate that illuminating area with adaptive frontlighting system is more reasonable than without such system, so driving safety is greatly improved.
