摘　　要：为提高车辆的制动性能,对汽车防抱死制动系统(anti-lock braking system,ABS)进行了模糊控制研究。通过对ABS特性进行分析,选取车辆滑移率作为控制量,运用模糊控制理论设计了ABS控制策略。基于CarSim与Simulink联合仿真平台,分别选取高、低附着系数路面验证ABS控制器的可行性,并与CarSim逻辑门控制模型进行对比分析。结果表明,所设计的控制器模型制动效果优于CarSim逻辑门限值控制模型,缩短了制动距离,降低了制动轮缸的工作压力,增加了制动器寿命,在提高制动稳定性的同时也增强了车辆的安全性能。In order to improve the braking performance and service life of the vehicle,the fuzzy control of anti-lock braking system(ABS)is studied.By analyzing the characteristics of ABS,the slip rate of vehicle is selected as the control quantity,and the control strategy of ABS is designed by using fuzzy control theory.Based on CarSim and Simulink co-simulation platform,the feasibility of ABS controller was verified on high and low adhesion road surface respectively,and was compared with CarSim logic gate control model.The experimental results show that the braking effect of the proposed controller model is better than that of the CarSim logic threshold control model,which shortens the braking distance,reduces the working pressure of the brake,improves the brake life,lightens the burden of the driver,improves the braking stability and enhances the safety of the vehicle.
