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

汽车在不同附着路面上制动时,常常会发生侧滑和甩尾等危险情况,为获得良好的制动效果,提高在不同路面上制动时的稳定性,必须对路面进行识别。文章基于CarSim软件建立汽车动力学模型,应用MATLAB/Simulink软件搭建了路面识别模块和ABS控制模块,分别在不同的路面上进行仿真试验,试验结果表明:基于路面识别的ABS控制系统相对于无路面识别的ABS控制系统的汽车缩短了制动时间和距离,提高了在不同路面上制动时的稳定性。

Vehicle braking in different roads often creates the dangerous events, such as side slip and wandering. The road surface must be identified in order to get good braking performance and improve the braking stability in different roads. Establishing the vehicle model using CarSim, using MATLAB/Simulink to build the road surface identification module and ABS control module and carry out the simulation in different roads. The results show that ABS control system based on the road surface identification module can shorten the braking time and reduce the braking distance compared with no road surface identification, improving the braking stability in different road.
