摘　　要：本文系统地分析了二自由度四轮转向汽车模型的运动方程。得到了质心侧偏角、横摆角速度,侧向加速度与前轮转角的传递函数。在此基础上,基于本实验室的四轮转向样车进行了前后轮转角成比例控制的四轮转向车辆(4WS)的运动学仿真,并针对仿真结果进行了系统的分析。结果阐明了四轮转向车辆与前轮转向车辆(2WS)相比的优势。并提出其发展方向。The equations of 2DOF four-wheel steering vehicle model are systemically analyzed in this paper, and the transfer functions about sideslip angle mass center, lateral acceleration and yaw velocity to front wheel steering angle are deduced.The locomotion simulations are processed according to the parameters of the four-wheel steering model vehicle in my lab whose control strategy is proportional control. The systemic analysis is done on the basis of the results of simulation. Finally, the advantages of 4WS vs. 2WS are illustrated evidently, and the developing directions of 4WS are predicted.
