摘要
为实现电动汽车制动防抱死控制,设计了电动汽车复合制动防抱死系统。首先建立了液压与电机制动防抱死模型;然后根据路面附着系数大小设计出复合制动防抱死控制模式;最后基于模糊PID控制设计了复合制动防抱死系统。在MATLAB/Simulink环境下同时建立复合制动与液压制动防抱死仿真模型,进行对比分析,结果表明:在不同附着系数路面,复合制动均能够有效控制滑移率,缩短制动时间和距离,回收制动能量;在对接路面,复合制动的控制效果更加理想,系统反应迅速、鲁棒性好。
In order to achieve anti-lock control of electric vehicle,a hybrid anti-lock braking system in electric vehicle is presented. Firstly,the models for hydraulic and motor anti-lock braking are established; secondly the hybrid anti-lock braking control mode is designed,according to the size of tire-road adhesion coefficient; finally,the hybrid anti-lock braking system is designed,based on the fuzzy-PID control. The simulation models for hybrid and hydraulic anti-lock braking are built simultaneously in MATLAB/Simulink in order to make comparative analysis,and the result shows that: on the different adhesion coefficient road,the hybrid braking can effectively control the slip ratio,shorten the braking time and distance,and recover the braking energy; on the joint-adhesion road,the hybrid braking can achieve an ideal control effect,and the system has rapid response and good robustness.
