摘　　要：IPID控制在车辆横纵向控制中有广泛应用,但是相同PID参数在不同车型间切换时存在兼容性差、鲁棒性差的问题。在MATLAB的仿真环境下,分别设计模糊控制器和PID控制器实现对已知系统的控制,均可得到较好的控制效果,然后分别加入相同的干扰,验证两种控制算法的抗干扰能力,以验证模糊控制器的优越性。在Precan软件中搭建车辆模型和道路模型,与MATLAB的模糊控制算法进行联合仿真,验证模糊控制可以实现车辆的横向控制,为车辆横纵向控制提供一种新思路。PID control is widely used in transverse and longitudinal control of vehicles,but there are problems of poor compatibility and poor robustness when the same PID parameters are switched among different vehicle models.In the simulation environment of MATLAB,the fuzzy controller and PID controller are designed respectively to realize the control of known systems,and both can get good control effects.Then,the same interference is added respectively to verify the anti-interference ability of the two control algorithms,in order to verify the superiority of the fuzzy controller.The vehicle model and road model are built in software Precan,and joint simulation with the fuzzy control algorithm of MATLAB is carried out to verify that the fuzzy control can realize transverse control of vehicles,which provides a new idea for transverse and longitudinal control of vehicles.
