| 摘 要： | 利用机械系统仿真软件ADAMS建立了一种新设计的四轮转向(4WS)汽车的整车虚拟模型；利用MATLAB/Simtdink建立了4WS汽车的控制策略；通过ADAMS与MATLAB／Simtdink交互式联合仿真，研究了闭环控制下4WS汽车的瞬态和稳态操纵动力学特性。另外，仿真比较了基于横摆角速度多状态最优控制方法下、不同底盘结构参数对车辆操纵稳定性的影响。

| Abstract: | A 4WS whole car virtual model is built with the mechanical multi-body dynamics software ADAMS in this paper. The control strategy of 4WS car was established by applying MATLAB/Simulink, and the research about the transient and steady steering dynamic characteristics of the car using 4WS closed-loop control is made by the interactive simulation of ADAMS and MATLAB/SIMULINK. The simulation results show that the different underpan parameters have important influence on the maneuvering stability of 4WS car based on the yaw angular-rate multiple status control, and the influence is analysed in the end. |
