摘　　要：针对纯电动公交车在交叉口区域的高能耗问题,设计纯电动公交车通行交叉口区域的节能驾驶策略。根据公交车通行交叉口区域的驾驶行为将交叉口场景划分为4类,并根据运动学关系划分信号灯剩余时长区间,将其分为6种情况,综合考虑交叉口上游路段和下游路段设计节能驾驶策略。结合基于纯电动公交车能耗特征的单位里程能耗模型和纯电动公交车匀速、加速以及减速策略,在MATLAB中开展仿真试验,验证所提出的节能驾驶策略。研究结果表明:提出的节能驾驶策略至少可以降低8%以上的能耗;对划分的6种情况而言,到达调整段时信号灯为绿灯的驾驶策略可降低8.70%~42.63%的能耗,到达调整段时信号灯为红灯的驾驶策略可降低9.85%~51.65%的能耗。In this study, an energy-saving driving technique for a pure electric bus in an intersection was designed to reduce the high energy consumption of pure electric buses in intersections. The intersection scene was divided into four categories according to the driving behavior, and the remaining time interval of the signal light was divided into six cases according to the kinematic relationship. The energy-saving driving technique was designed, considering the upstream and downstream sections of the intersection. With the energy consumption model of a unit kilometer based on the energy consumption characteristics of the pure electric bus and its constant speed, acceleration, and deceleration, simulations were performed in MATLAB to verify the proposed energy-saving driving technique. The results show that it can reduce energy consumption by at least 8%. For the six cases, the energy consumption can be reduced by 8.70%-42.63% when the signal light is green and 9.85%-51.65% when the signal light is red.
