摘　　要：为研究在车路协同背景下载货汽车如何组成车队能更加节能的问题,选取3种经典货车模型为研究对象,设定行驶速度为22 m/s、车间距为4.4 m,分别进行了单车、两车及三车的单一车型(同构)和多种车型(异构)队列仿真。建立了较为理想的仿真计算域,并通过XFlow软件分析了整体车队能耗情况及节能效果。结果表明:在两车队列中,节能率最高和最低的车队分别为2-2z车队和6-2z车队,节能率分别为20.67%和3.12%;在三车队列中,节能率最高和最低的车队分别为2-2-2z车队和6-6-2z车队,节能率分别为31.08%和3.22%。In order to study the issue of how to form a more energy-efficient platoon of trucks under the background of vehicle road collaboration,three classic truck models were selected as the research objects and simulation parameters were set with driving speed of 22 m/s and spacing of 4.4 m.Single vehicle(homogeneous)and multiple vehicle(heterogeneous)queues of single,two,and three vehicles were simulated,an ideal simulation calculation domain to analyze the overall energy consumption and energy-saving effect of platoon through XFlow was established.The results showed that the platoon with the highest and lowest energy efficiency rates among the two platoon were the 2-2z and 6-2z fleets,with queue energy efficiency rates of 20.67%and 3.12%,respectively.The teams with the highest and lowest energy efficiency rates among the three platoon are the 2-2z and 6-6-2z fleets,respectively,with queue energy efficiency rates of 31.08%and 3.22%.
