摘要
通过对载重车斯太尔1291．260／N56／4X2进行动力学分析，在Matlab／Simulink下建立了四轮汽车的基本制动模型和具有逻辑门限控制算法的ABS制动模型。仿真图形显示，具有ABS的制动模型，滑移率被控制在0．1～O．2范围内，轮速随车速逐渐减为零，说明基于本模型的ABS控制方法基本合理。
This paper made an analysis of dynamics on truck CQ1291. 260/N56/4 × 2 and developed a basic braking system model of four wheels and a braking system model with ABS in MATLAB/SIMULINK environment. From simulation graph, slip rate was controlled between 0. 1-0. 2 and speed of wheels with speed of the vehicle was reduced to zero. It shows that the ABS control logic based on this model is reasonable.
