摘要/Abstract

摘要： 针对公交车进出站过程速度波动明显，能耗较高的问题，本文采集纯电动公交车自然驾驶数据，以进出站速度随距离的变化关系、进出站加速度分布区间及进出站时间3个指标分析公交车进出站驾驶行为参数特性。统计进出站百公里能耗及瞬时能耗与加速度的变化趋势，分析进出站的能耗特征。在此基础上，将进出站路段划分为定速段、调整段和恢复段，并依据进站时站内已经停靠公交车的影响，将进出站场景分为3类。进出站实质上是“减速-加速”过程，提出以加速特征参数表征的加速策略和恒减速策略，以此分别针对3类进出站场景提出几种节能驾驶策略，最后，基于AVL CRUISE仿真验证节能驾驶策略的有效性。结果表明，相比自然驾驶情况，本文提出的进出站节能驾驶策略在纯电动公交车进出站过程中节省电能达到12.17%~44.43%，具有可观的节能潜力。

Abstract: Focusing on the obvious speed fluctuation and high energy consumption in the process of bus entering and leaving stops, this study collected the real driving data of pure electric buses and analyzed the driving behavior characteristics with three indicators: the relationship between speed and distance, the distribution interval of acceleration, and the time of entering and leaving stops. The energy consumption performance was analyzed by counting energy consumption per 100 km and the change trend of instantaneous energy consumption and acceleration. On this basis, the process of bus entering and leaving stops is divided into fixed speed section, adjustment section, and recovery section, and the scenes of entering and leaving stops were divided into three categories according to the influence of the bus had parked in the stop. The process of entering and leaving stops can be simplified as a "deceleration and acceleration" process. The acceleration strategy with acceleration characteristic parameters and constant deceleration strategy was proposed. Based on these strategies, energy-saving driving strategies were proposed for the three entering and leaving stops scenarios. Finally, the effectiveness of the energy-saving driving strategy was verified based on the simulation of AVL Cruise. The results show that the proposed driving strategy can save 12.17%~ 44.43% of electric energy in the process of entering and leaving stops compared with the original driving situation, which has considerable energy-saving potential.

Key words: urban traffic, energy-saving driving strategy, simulation experiment, pure electric bus, entering and leaving stops
