摘　　要：基于汽车方向盘转角,建立基于方向盘转角的AFS模型,同时基于预瞄角度建立基于预瞄角度的AFS模型。解决了夜间行驶时车辆在弯道上视线盲区的问题,提高了驾驶人夜间行车的安全性。在matlab/simulink的环境中建立相应的汽车前大灯水平角度调整的控制算法,并在40 km/h、60 km/h、80 km/h和100 km/h的车速下进行了仿真对比。仿真结果表明:汽车AFS的前大灯水平调整角度的变化对车速不敏感,基于预瞄角度的AFS的水平调整角度的变化曲线更加平滑,并且没有出现调整角度的突然增大和减小。One AFS model was established based on steering wheel angle,and another AFS model was established based on the preview angle.the control algorithms of headlights＇ horizontal angle adjustment were established in the matlab/simulink.The problem of blind area in the comers was and solved driving safety when driving at night was improved.Simulation results of 40 km/h,60 km/h,80 km/h and 100 km/h shows that the headlight horizontal adjustment angle is not sensitive to the variation of speed; The curve of horizontal adjustment angle of AFS based on the angle preview is smoother,and the adjustment angle does not appear suddenly increases and decreases.
