摘　　要：为了构建基于实际情况的太原市轻型车道路行驶工况,采用自主行驶法采集试验数据并从中提取出2 208个有效运动学片段,通过因子分析、K-means聚类分析方法以及相关系数比较最终拟合出长度为1 184 s的太原市轻型车实际行驶工况,将之与国内其他城市以及国际4类标准工况进行对比分析,得出太原市轻型车行驶工况具有加减速比例高、匀速行驶比例低和低速行驶比例高等特点。In order to build the driving cycle of light vehicle based on the actual situation in Taiyuan City,the experimental data were collected by autonomous driving method and2208effective kinematics fragments were extracted.Through factor analysis method,K-means clustering analysis method and the comparison of correlation coefficient,the actual driving cycle of1184seconds in length of Taiyuan was fitted out,which was compared and analyzed with other domestic cities and the4commonly used international standard driving cycles,it was concluded in the paper that the driving cycle of light vehicle in Taiyuan was characterized by high acceleration and deceleration ratio,low constant speed driving ratio and high low speed driving ratio.
