运用Carsim软件建立车辆动力学仿真模型，以临界附着系数作为小客车急转向行车风险评价指标，借助正交试验，综合分析小客车在直线路段急转向时车速、方向盘转角及转向用时对行车风险的影响强弱和显著性。结果表明：影响强弱由大到小依次为方向盘转角、车速、转向用时，且方向盘转角、车速影响显著，而转向用时影响不显著。
運用Carsim軟件建立車輛動力學倣真模型，以臨界附著繫數作為小客車急轉嚮行車風險評價指標，藉助正交試驗，綜閤分析小客車在直線路段急轉嚮時車速、方嚮盤轉角及轉嚮用時對行車風險的影響彊弱和顯著性。結果錶明：影響彊弱由大到小依次為方嚮盤轉角、車速、轉嚮用時，且方嚮盤轉角、車速影響顯著，而轉嚮用時影響不顯著。

The simulation model of the dynamic characteristic of vehicle is established using Carsim, the criti-cal adhesion coefficient is used as the evaluation index of vehicle moving risk, with the help of orthogonal ex-periment, comprehensive analysis of the significance and significant influence of speed, steering wheel angle, turning time when vehicle moving on straight sections. The results show that the significance of factors is as follows:steering wheel angle, speed, turning time, steering wheel angle and speed have great significant in-fluence but the turning time has no significant influence.
