　　不论是采用逻辑门控制算法还是采用PID控制算法，目前汽车制动防抱死系统ABS的研究往往都没有考虑到路面的不平度。为了提高ABS的精度，降低开发成本，提高匹配效率，首先必须获得车辆各子系统的拓扑结构，再用多体动力学软件SIMPACK建立整车模型。为了更加逼真的模拟实际道路情况，采用B级道路谱，在MATLAB中搭建4通道ABS的滑模控制器，进行了联合仿真。该仿真模型，可以用于模拟分析不同工况、不同控制参数对制动性能的影响，可以方便快捷地验证不同控制策略的有效性。结果显示：该方法可以逼真地模拟实际车辆制动过程，有效地缩短了制动时间和制动距离，提高了车辆的安全性，同时为ABS的研发提供了一种新途径。

Whether using the logic gate control algorithm or using PID control algorithm , the present study did not take into consideration of the road surface roughness .In order to improve the accuracy , matching efficiency and reduce the cost of development .First a multi-body dynamic model of a full ve-hicle was established by SIMPACK , then, sliding mode controller for four-wheel vehicle braking was de-signed under the MATLAB/simulink environment , at last co-simulation was carried out .It's easy to emu-late the effect of deferent working conditions and control parameters on braking performance .The results showed that the model can well simulate the true braking condition and effectively shorten braking dis -tance and time , improve the safety of the vehicle and also provides a new method for the research of ABS.
