摘要
基于Matlab/Simulink仿真技术,充分考虑车辆弯道制动时因为纵向和侧向加速度的存在而引起轮胎所受垂直载荷的变化,建立了汽车弯道行驶的八自由度整车动力学仿真模型,嵌入了ABS控制逻辑模型。对弯道制动工况下的车速、横摆角速度、转弯半径以及车轮滑移率的变化进行了仿真计算,结果表明该模型可以全面准确的模拟车辆在弯道制动时的运动状况,为开发和改进ABS系统提供了很好的参考依据。
Based on Matlab/Simulink simulation technology,considering the influence of wheel vertical load,a dynamic model of 8-degree of freedom for an entire vehicle with ABS control logic was established.Based on the model,the changes of vehicle speed,yaw rate,turning radius and slip ratio were simulated.The results show that the model can accurately simulate the moving situations of vehicle under braking in turn condition.The model can provide a good reference for further research on ABS.
