直线路段小客车急转向行为行车风险分析

摘要

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。%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.
