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 the problem that the wheel slips easily during the starting or accelerating process of the vehicle.In this paper,a single wheel vehicle is taken as the research object.A vehicle model,a tire model and a motor model are established in Matlab/Simulink.The fuzzy controller is designed,and the simulation research on the model of automobile driving anti slip control is carried out,and the simulation curve is obtained.The results show that the vehicle model is consistent with the actual,the fuzzy control algorithm to design of real-time vehicle torque adjustment,so as to effectively control the vehicle slip rate,improve vehicle driving stability,its performance is better than the traditional PID controller,it has the practical application value.

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