摘　　要：通过对单轨二自由度四轮转向车辆模型的分析,概述四轮转向车辆的基本运动关系。在比较后轮转角大小、转角相位对转向工况的影响后,用理论分析验证四轮转向对提高车辆机动性和操纵稳定性方面的作用,得出四轮转向车辆性能更为优势的结论,为开展4WS车辆的研究铺垫基础。The analysis on single-track tour-wheel-steering vehicles model is put forward. The basic movement relations of fourwheel-steering vehicles are outlined. The advance effect of mobility and handling stability are validated with the four wheel steering theory analysis after rear wheel steering angle size and phase are compared to influence of four wheel steering. The conclusion is drawn that four wheel steering performanee is better, The foundatinn is laid for research on 4WS vehicle.
