本文中提出了一种根据车队出行里程分布来计算插电式混合动力汽车( PHEV)车队的平均油耗的方法,并利用北京市区乘用车出行里程分布,计算了丰田Prius Plug-in、通用Volt和菲斯科Karma在北京地区使用的平均油耗。结果表明,3种车型在北京市区的平均100km油耗分别为3.37、1.83和3.91L；其中Prius Plug-in和Volt的平均油耗比传统车丰田Corolla分别降低58.47%和77.45%；该方法可用于计算PHEV车队的平均油耗和单个PHEV在某段较长时间内使用的平均油耗。%In this paper, a method for calculating the average fuel consumption of PHEV fleet is proposed based on trip range distribution, and by using the trip range distribution of passenger cars in Beijing city, the aver-age fuel consumptions of three PHEVs ( Toyota Prius Plug-in, GM Volt and Fisker Karma) are calculated. The re-sults show that the average fuel consumptions of above three PHEVs running in Beijing city are 3. 37L/100km, 1.83L/km and 3. 91L/100km respectively, in which the average fuel consumptions of Prius Plug-in and Volt are 58.47% and 77.45% less than that of traditional vehicle Toyota Corolla. The method proposed can be used to cal-culate the average fuel consumption of PHEV fleet and individual PHEV over a relatively long period.
