摘　　要：基于Matlab/Simulink建立了考虑汽车车身侧倾转向的3自由度仿真模型,研究了车轮外倾角对汽车高速转向稳定性的影响。结果表明前轮正外倾角、后轮负外倾角有利于提高转向稳定性,特别是在大转角的危险工况可以避免发生侧滑和侧翻。The simulation model considering vehicle body list steering with three degrees of freedom is constructed based on Matlab/Simulink.Studied the influence on vehicle high speed steering stability caused by vehicle camber.The conclusion is that positive camber of front wheel and negative camber of rear wheel are good to increasing the steering stability,especially on the big camber danger condition it can avoid occurring sideslip and side-reverse.
