根据汽车转向及侧倾运动方程,并结合驾驶员视野和安全停车距离随车速变化的规律,建立了自适应前照灯系统(AFS)的实时三维控制模型,采用Matlab/Simulink设计仿真程序对其进行模拟,结果表明,根据车速、前轮转角、前后轮侧偏角、车身质心侧滑角和车身侧倾角来综合控制汽车在转向行驶时的前照灯照射距离及角度具有良好的响应。 According to the vehicle steering and roll motion equation, combined with the change of driver’s field of view and safety parking distance with vehicle speed, a real-time three-dimensional control model of adaptive headlamp system (AFS) was established. The simulation program was designed by Matlab / Simulink Simulation results show that the vehicle headlight illumination distance and angle have a good response according to vehicle speed, front wheel angle, front and rear wheel slip angle, body center of mass side slip angle and body roll angle.
