摘　　要：为解决基于规则的插电式混合动力汽车(PHEV)能量管理策略必须保留混合动力系统容量冗余以应对不可预测的驾驶员行为,从而影响系统效率的问题,研究了基于优化的智能交通系统(ITS)能量管理和经济行驶算法,利用ITS提供的信息对高压电池的充、放电以及发动机的起动和关闭进行控制,利用上海市行驶工况数据进行了仿真,表明了该控制策略的有效性。Rule-based energy management strategy used on Plug-in Hybrid Electric Vehicles(PHEV)has its innate disadvantage that the whole hybrid powertrain system has no choice but to reserve capacity as redundancy to response to the unpredictable driver behaviors in the near future,which could lead to non-optimal system efficiency as expected.This paper focuses on the optimization based algorithm for energy management and economic driving over a pre-selected horizon using messages from Intelligent Traffic System(ITS),which is proposed to schedule the charging or discharging of the high voltage battery,and when to turn on/off the engine and drive electrically.The benefits of the proposed predictive intelligent control strategy are shown by simulations with data extracted from mega city driving situation in Shanghai.
