摘  要:为解决车辆在起步或加速过程中车轮容易打滑的问题,本文以单轮车辆为研究对象,在Matlab/Simulink中建立了车辆模型、轮胎模型和电机模型。设计了模糊控制器,并对建立的汽车驱动防滑控制模型进行仿真研究,得出仿真曲线。结果表明,建立的汽车模型符合实际,设计的模糊控制算法能够实时对车辆转矩进行调节,从而有效控制汽车滑移率,提高汽车驱动稳定性,其性能优于传统的PID控制器,具有较高实际应用价值。

Abstract:In order to solve theproblem that the wheel slips easily during the starting or accelerating processof the vehicle.In this paper,a single wheel vehicle istaken as the research object.A vehicle model,a tiremodel and a motor model are established in Matlab/Simulink.The fuzzy controlleris designed,and the simulation research on the model ofautomobile driving anti slip control is carried out,andthe simulation curve is obtained.The results show that the vehicle model isconsistent with the actual,the fuzzy control algorithmto design of real-time vehicle torque adjustment,so asto effectively control the vehicle slip rate,improvevehicle driving stability,its performance is betterthan the traditional PID controller,it has thepractical application value.

Keywords:electric vehicle;slip rate; antiskid control;fuzzy control;PID control
