【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。
[Abstract]:Taking Harbin passenger vehicle as the research object, the operating condition data of the passenger car running in Harbin main urban area were tested by using GPS equipment, and the collected speed data curve was divided into several short stroke segments. Eleven characteristic parameters of the most representative working conditions were extracted, and the feature parameters were reduced and classified by principal component analysis (PCA) and cluster analysis (FCM). By using the correlation coefficient, the typical driving conditions of passenger cars in Harbin are constructed and compared with those of NEDC and Japan10-15 passenger cars. The results show that the average speed of passenger cars in Harbin is 15 km/h, lower than that of NEDC and Japan10-15 passenger cars, the proportion of acceleration and deceleration characteristic parameters is 33.57% and 29.70 respectively, which is higher than that of NEDC and Japan10-15 passenger cars. There is a great difference between the existing European and Japanese road operating conditions and the passenger vehicle driving conditions in Harbin urban area. The running conditions based on the running data can better reflect the running characteristics of local passenger cars.
