基于道路自识别的汽车ABS模糊PID控制仿真

Simulation of Vehicle ABS Fuzzy PID Control Based on Road Surface Automatic Identification

针对汽车防抱死系统控制问题,基于CarSim软件建立汽车动力学模型,应用Matlab/Simulink设计了ABS模糊PID控制器,搭建了路面识别控制器模型,分别在高低对接路面和高低对开路面上通过carsim与Matlab/Simulink联合仿真实验进行ABS控制策略仿真实验验证。仿真实验结果证明,基于道路自识别的模糊控PID制相对无路面识别固定滑移率控制的汽车缩短了制动时间和距离,提高了汽车制动的稳定性。

For the control of a vehicle anti-lock braking system, a vehicle dynamics model is established based on CarSim us- ing Matlab/Simulink design of ABS Fuzzy PID controller, and the road surface identification controller model is constructed, ABS control strategy simulation experiments are implemented respectively on the docking surface height and the height of an open face through CarSim and Matlab / Simulink co-simulation experiment. Simulation results show that for the cars based on road self-recognition of fuzzy control PID system, the braking time and distance are shortened and the braking stability is im- proved compared with those with no road identification control.
