摘　　要：利用ADAMS软件的专业模块CAR,建立了四轮转向汽车(4WS)的整车虚拟样机模型;利用MATLAB模糊控制工具箱建立了模糊控制策略;通过ADAMS/Control接口进行了ADAMS与MATLAB的联合仿真.在此基础上,对方向盘转角阶跃试验及单移线试验进行了仿真分析.结果表明,模糊控制更具鲁棒性,且能更好地提高汽车的操纵稳定性.A four-wheel-steering virtual prototype model was built by use of a professional module,CAR from ADAMS,and its fuzzy control strategy model was established with the aid of the fuzzy logic toolbox of MATLAB.The two models were co-simulated by means of ADAMS/Control.Simulation analysis was carried out on both step response test and lane change test.The results indicated that the fuzzy control possessed much more robustness and could obviously improve the control stability of a vehicle.
