Abstract: The optimal speed planning for connected HEVs under urban traffics with multiple intersections was investigated. The feasibility of using the double-layer pseudo-spectral method to optimize the energy management strategy of HEVs was discussed. Firstly, based on signal phases and timing, the optimal speed was obtained via pseudo-spectral method to ensure that the vehicle might pass through the intersections without stopping. Then, based on the planned speed, the power distribution between engine and battery was arranged with the goal of minimizing vehicle energy consumption. Simulation results show that the proposed method may reduce fuel consumption by 6.9% compared with manual driving, and the effectiveness of the proposed strategy is further verified by real vehicle tests.

摘要: 研究了联网场景下面向连续多路口的混合动力车辆节能速度规划问题,探讨了使用双层伪谱法优化城市交通中混合动力车辆能量管理策略的可行性。根据交通信号灯的时序信息,以保证车辆中途不停车顺利通过各路口为目标,使用伪普法规划最佳的车速轨迹。根据规划的车速,以车辆能耗最低为目标,实现发动机和动力电池间功率输出的经济性分配。仿真结果表明,与人工驾驶相比,所提方法可将燃油消耗量减少6.9%,实车试验结果进一步验证了所提策略的有效性。
