摘　　要：根据国内外相关法规、标准以及中国的道路交通情况,对自适应前照灯的弯道照明模式进行了系统研究,建立相应的数学模型。通过对停车视距和汽车转弯半径的几何分析,推导出了水平调整角度和转弯半径及车速间的函数关系。根据道路圆曲线最小半径一般值得到前照灯最大调整角度,分析了左右前照灯的配合调整方式,并通过仿真验证了整个数学模型的可行性。According to domestic and international regulations, standards and road conditions in China, the mathematical model of the bending mode was built. A functional relationship among the headlight adjusting angle, turning circle and speed was established through the geometrical analysis of stopping sight distance and turning radius. Based on the general value of minimum radius of circular curve, the maximum adjusting angle of the headlight and the cooperation of the left and right headlights were determined. The feasibility of this mathematical model was validated by simulations.
