| 摘 要： | 在Matlab／Simlink下建立了八自由度车辆系统的仿真模型。采用模糊控制方法，设计了基于滑移率的ABS控制算法。针对车辆转弯制动工况，对15m／s、20m／s、25m／s三种车速进行了仿真分析。仿真结果表明所建立的ABS控制器能有效提高车辆的制动性能以及中低车速下的稳定性，但定性分析表明车辆在高速工况下出现不稳定现象。为此利用稳定性判定式，对车辆转弯制动ABS控制下的稳定性做了定量判定。判定结果表明，高速时车辆仅有ABS控制并不能达到稳定性控制的要求。

| Abstract: | Eight degrees of freedom vehicle model is established in Matlab/Simlink. Using the method of fuzzy control, the Anti-lock Braking System（ABS） control algorithm is designed based on slip ratio. Simulation analyses are done at speed of 15 m/s ,20 m/s ,25 m/s under tuming braking. The results show that the vehicle braking performance and vehicle stability at middle or low speed are improved by the ABS controller;but qualitative analyses indicate that phenomenon of vehicle instability is appeared at high-speed conditions. The tuming braking stability under ABS controller is judged quantificationally by the stability judging formula. The results show that the demand of the turning bra- king stability is not meet at high-speed conditions only with ABS controller. |
