摘　　要：车辆在弯道制动的条件下很容易失去稳定性,防抱死系统(ABS)在很大程度上提高了车辆转弯的稳定性。在低成本硬件条件下搭建起基于MATLAB/x PC的半实物仿真平台,通过MATLAB/Smulink建立8自由度仿真模型,采用控制鲁棒性较强的模糊PID的ABS控制策略,对客车在高低附着系数路面制动转弯的情况下进行了硬件在环测试。测试结果表明:该控制算法能有效提高汽车稳定性,使滑移率较好地控制在最佳值0.2附近,具有更好的鲁棒性和自适应能力。Vehicle in cornering braking conditions is very easy to lose stability, anti lock braking system （ABS） greatly improves the stability of the vehicle turning. The semi physical simulation platform of MATLAB/xPC is built under the condition of low cost, eight degrees freedom simulation model is established with MATLAB/Smulink. Hardware-In-the-Loop test system of bus in cornering braking is carried out by the robust fuzzy PID control strategy. The test results show that the control algorithm can effectively improve the stability of the vehicle, and the slip ratio is better and is controlled near the optimal value of 0.2.
