| 摘要： | This research project compares the in-use and laboratory-derived fuel economy of a medium-duty hybrid electric drivetrain with engine off at idle capability to a conventional drivetrain in a typical commercial package delivery application. Vehicles in this study included eleven model year 2010 Freightliner P100H hybrids that were placed in service at a United Parcel Service (UPS) facility in Minneapolis, Minn., during the first half of 2010. These hybrid vehicles were evaluated for 18 months against eleven model year 2010 Freightliner P100D diesels that were placed in service at the same facility a couple months after the hybrids. Both vehicle study groups use the same model year 2009 Cummins ISB 200 HP engine. The vehicles of interest were chosen by comparing the average daily mileage of the hybrid group to that of a similar size and usage diesel group. The driving characteristics of the two study groups were examined in detail by collecting and analyzing two periods of Global Positioning System and controller area network (CAN) bus data. The results of this drive cycle study indicated a need to have the two investigated groups switch route assignments mid-study because of significantly different driving patterns, which UPS accommodated, to facilitate an accurate comparison. |
