摘　　要：提出当车辆在弯道转向时,可以通过车速和前轮转向角度作为输入信号,根据前照灯弯道照明距离应大于安全行驶距离的控制策略,以四轮动态转向模型和ABS制动模型为基础,计算前照灯的旋转角度。经由基于MATLAB/Simulink的数值计算程序和专门设计的采用向心加速度传感器的LabVIEW实车测控系统,对比验证了AFS前照灯弯道旋转计算模型的有效性。According to the control strategy that headlamp illuminating area should cover safety distance on curving road,this paper proposed that four wheels steering model and ABS braking model can calculate headlamp swiveling angle,as inputs of vehicle speed and front wheel steering angle.By the comparison of simulations based on Matlab/Simulink with experiments of the designed control and testing system based on LabVIEW programs by centripetal acceleration sensor,it was testified effectively.
