摘　　要：为了反映插电式混合动力公交车(PHEB)在实际公交工况运行时的真实油耗,提出了一种基于实时交通信息的工况构建方法。首先,通过车载传感器获取实时交通信息,利用D-S证据理论对获取的多种传感器信息进行多源信息融合。其次,根据实车采集的原始行驶数据,对车速片段进行划分。利用马尔可夫转移矩阵,结合蒙特卡洛方法构建了全局行驶工况。通过实时更新的交通信息对构建的全局行驶工况进行实时更新,从而进一步反映实时的道路行驶路况。最后,通过与实际工况数据的比较,验证所提出方法的有效性。研究结果表明:基于实时交通信息构建的行驶工况与实际工况较为吻合,主要特征参数的相对误差均在5%以内,百公里油耗与实际工况的百公里油耗相对误差为1.8%。In order to reflect the real fuel consumption of plug-in hybrid electric bus( PHEB) in the actual bus driving cycle,a driving cycle method based on real-time traffic information was proposed. Firstly,the real-time traffic information was obtained by on-board sensors,and multi-source information fusion was carried out by using D-S evidence theory. Secondly,according to the original driving data collected by real vehicles,the speed segments were divided. The global driving cycle were constructed by using Markov transition matrix and Monte Carlo method. The real-time traffic information was updated to further reflect the real-time road conditions. Finally,the effectiveness of the proposed method was verified by comparing with the actual data.The results show that the driving cycle based on real-time traffic information are more consistent with the actual driving cycle. the relative errors of the main characteristic parameters are less than 5%,and the relative error of 100 km fuel consumption based on real-time traffic information is 1.8%.
