摘要
研究在不同转向车速下的汽车前照灯转角优化问题,首先在车辆二自由度模型的基础上建立了前照灯转向模型,应用线性二次优化理论对前照灯转角进行优化;其次在MATLAB/Simulink中对模型进行了仿真分析;最后根据所得的结果利用Proteus软件进行AFS的硬件设计与仿真。通过Proteus的仿真结果表明,所设计的电路合理,前照灯转动的角度与预期的一致,证明了所建立的车辆模型和转向灯模型是正确的。
It studies the optimized headlamp steering angles on different speed. Firstly, based on the two-degreeof-freedom vehicle model, it establishes the headlamp steering model, and uses linear quadric to optimize head- lamp steering angles, then it simulates the model in the software of Matlab/Simulink. Based on the results, it applies the software of Proteus to design the hardware of the AFS and simulate. The simulation results from the Proteus show that the design circuit is reasonable, and the drive degrees of the AFS are Consistent with the expected, the vehicle dynamic model and steering model are proved to be right.
