摘　　要：通过不同工况时车辆对转向特性要求的分析 ,指出车辆的转向特性应该随着车速及方向盘转向角的变化而变化 ,提出当车速降低或方向盘转向角急速增大时 ,转向应该具有减小不足转向或增大过度转向的趋势 ;反之转向特性应具有减小过度转向或增加不足转向的趋势。通过对东风 -雪铁龙系列轿车后桥随动转向技术的实例分析 ,验证了这一结论的正确性。Through explaining what is the steering behavior of a car and analyzing on the demands of steering behavior in all operating modes, this paper pointed out that the steering behavior should be changed with the velocity and the steering angle. Then the conclusions are put forward,i.e. the carriage must have the trend of lowering under-steer or raising over-steer when the velocity is reducing or the steering angle is increasing rapidly, and it is the conversely the other way round. Further more, this paper analyzed the slave-steer of the Dongfeng-citroen rear-axle, which proved that the conclusion is feasible.
