Correction Method of the Angle of Vehicle Adaptive Front-lighting System Based on Wheel Slip Angle

结合汽车的动力学特性,提出了利用前后车轮侧偏角之差来改善AFS转角计算精度的方法,建立了AFS转角修整模型,在此基础上,运用整车动力学仿真软件TESIS/veDYNA软件对该方法进行了仿真分析。仿真结果表明,该法对研究车型的AFS转角的修整率为17.21%～29.47%。

In order to improve the calculation accuracy of the angle of AFS, we integrate the ki- nematics property of vehicle to propose a correction model to improve the calculated result by the difference between values of the side slip angles of the front and rear wheels. And then,we establish a simulation mode to simulate and tion results, this by 17.21% to 2 1 in the analyze. method 9.47%. TESIS/veDYNA software According to the la can correct the AFS angle
