摘　　要：以哈尔滨市乘用车作为研究对象,利用GPS设备对哈尔滨主城区运行的乘用车工况数据进行了测试,将采集到的车速数据曲线分割为多个短行程片段,提取了片段中最具有代表性的11个工况特征参数,利用主成分分析法和聚类分析法对特征参数进行了降维和分类处理。利用相关系数提取了代表性行驶工况片段,进而构建了具有代表性的哈尔滨市主城区乘用车典型行驶工况,并与NEDC和Japan10-15乘用车道路工况进行了对比分析。分析结果表明:哈尔滨城区乘用车工况的平均车速为15 km/h,低于NEDC和Japan10-15乘用车行驶工况;加速、减速特征参数比例分别为33.57%和29.70%,高于NEDC和Japan10-15乘用车行驶工况的相关参数;现有的欧洲和日本道路工况参数与构建的哈尔滨市城区乘用车行驶工况具有较大的差异,利用基于运行数据构建的行驶工况可以更好地反映地方乘用车的运行特征。Taking the passenger cars in Harbin as the study objects,the data of the driving cycle of passenger cars in the representative distracts of Harbin is tested by using GPS.The collected data curves are divided into many short segments,and the most representative 11 parameters are extracted to reduce dimension and classify by using the principal component analysis and cluster analysis.The representative driving segments are extracted with relative coefficient,then driving cycle of passenger cars in the representative distracts of Harbin is constructed,which is comparatively analysed with those of NEDC and Japan 10-15.The analysis result shows that（1） the average speed of passenger cars in Harbin is 15 km/h,which is lower than the driving conditions of NEDC and Japan 10-15;（2） the proportions of characteristic parameters including acceleration,deceleration are 33.57% and 29.70% respectively,which are higher than the relative parameters of NEDC and Japan10-15;（3） there are many differences in the driving cycles among Europe,Japan and Harbin.The driving conditions based on running data can better reflect the local operating characteristics of passenger cars better.
