| 摘 要： | 运用ADAMS软件建立了新型四轮转向(4WS)汽车整车虚拟样机模型，利用该模型对比了基于横摆角速度多状态最优控制的4WS汽车同前轮转向(FWS)汽车及其它不同控制算法的阴轮转向汽车(后轮比例于前轮转角算法及后轮转角比例于横摆角速度算法)的操纵稳定性。仿真结果表明，基于横摆角速度多状态最优控制的4WS汽车，其各项评价指标优于FWS汽车以及采用另外两种控制方法的4WS汽车。

| Abstract: | The virtual prototype model of a new type 4WS vehicle is created with ADAMS software.With the model,handling and stability of a yaw-rate-based multi-state optimal control 4WS vehicle is compared with that of a FWS vehicle and that of a 4WS vehicle with other control algorithms(the rear wheel angle in proportion to the front wheel angle algorithm and the rear wheel angle in proportion to yaw rate algorithm).It is shown by simulations that all evaluation indices of the yaw-rate-based multi-state optimal control 4WS vehicle is prior to that of a FWS vehicle and 4WS vehicles with other algorithms. |
