摘　　要：车辆夜间转弯时的转角特性是汽车随动转向前照灯系统(AFS)的关键特性之一。介绍了AFS系统的基本原理,分析了当前国内外对汽车AFS头灯随动转向规律的研究成果。在此基础上提出了两种新的转角特性曲线模型,同时建立了评价该特性曲线性能的数学模型,并结合具体车型对前照灯的随动转向效果在matlab软件中进行了分析验证,得到了分析计算结果。该结果数据说明设计的转角特性所确定的头灯转角是合适的,也进一步证明了曲线型转角特性的性能优于直线型转角特性。The corner characteristic during driving at night is one of the critical characteristics of the vehicle Adaptive Front-lighting System（AFS）.The basic principle of AFS is introduced,and the result of the current study on headlamp follow-up steering law at home and abroad is analyzed as well.On the basis of that,two new curve models for corner characteristic are put forward.then a mathematical model to evaluate the performance of the corner characteristic curve is established.In addition the follow-up steering effect of headlights combining specific vehicle typeis analyzed and tested in matlab,a result after analyzing and calculating is obtained,which result demonstrates that the corner based on corner characteristic of the headlight is appropriate,and the curved corner feature is further proved to be superior to linear corner feature.
