摘要
为了改善电动车的可操作性和稳定性,对电动车制动防抱死控制系统进行了研究.基于电动机与车轮胎直接相连的结构,设计控制器以期得到满意的控制性能.首先提出一种基于模糊控制器和PID算法的制动防抱死控制系统;而后针对汽车纵向四轮模型,设计了模糊PID算法;最后通过试验结果证明了该控制算法的有效性.尽管道路条件的变化不同,电动车制动防抱死控制系统表现了满意的控制性能.
This paper investigates the use of Antilock Brake Control System for improving handling and stability of Electric Vehicles.Based on its structural merit that electric motors are connected directly to the tires,the implementation of such a control system is expected to achieve satisfactory control performance.A fuzzy and PID control algorithm of Antilock Brake Control System is presented,and the fuzzy PID controller is designed according to the longitudinal 4-wheel brake model.The effectiveness of the algorithm is verified by the experimental results.It is clarified that the handling and stability of electric vehicle is improved and the control system still maintain satisfactory control performance despite the change of road surface condition.
