摘　　要：组建插电式混合动力电动汽车(PHEV)车队,供不同通勤距离的用户作日常出行使用,考察PHEV在道路上的实际能耗。同时参照ECE R101在实验室进行PHEV的能耗试验。通过对实验室能耗试验结果采用利用系数或平均充电行驶里程权重系数进行加权,将结果与道路能耗试验结果进行对比,以探讨更能反映PHEV道路实际能耗的综合评价方法。结果表明:采用利用系数或平均充电行使里程权重系数(在短距离内)两种方法都能预测实际应用中CD模式的能耗情况。但应用不同权重系数对实验室能耗综合结果与道路实际能耗都存在超过10%的差异。为使实验室试验更准确地反映PHEV道路实际能耗,除调整综合权重系数外,还须对实验室的条件进行调整或补充。A fleet of plug-in hybrid electric vehicle（ PHEV） is formed covering private cars with different commuting distances for routine trip to investigate the real-world energy consumption of PHEV on-road. At the same time an energy consumption test of PHEV in laboratory is also conducted with ECE R101 as reference. Based on the results of laboratory test,both schemes of weighting by average charged range（ ECE R101） and utility factor（ SAE J2814） are adopted for post-processing and the results of energy consumption are compared with that of fleet＇s data for exploring a comprehensive evaluation method better reflecting the real-world PHEV energy consumption on road.The results show that both schemes can well predict the energy consumption of PHEV in real operation,but with different weighting factors the results of comprehensive energy consumption all have a some 10 % deviation from realworld data. So for laboratory test to more accurately reflect the real road energy consumption of PHEV,both weighting factors and the conditions of laboratory test should be adjusted.
