The invention discloses a self-adaptive ECMS energy management strategy based on real road condition information, and the strategy takes a PHEV vehicle with a double-shaft parallel configuration as a research object. Comprising the steps of whole vehicle modeling, ECMS problem construction, ECMS constraint SOC trajectory correction, equivalent factor self-adaption, SOC global planning based on urban actual driving road condition information, upper layer constraint control optimization based on engine starting and stopping, control strategy model building, result simulation analysis and the like. The result shows that compared with a CD-CS strategy, the fuel economy of the PHEV is improved by 7.85%, and compared with a Time-AECMS strategy and a Distance-AECMS strategy, the fuel economy of the PHEV is improved by 6.44%, and the fuel economy of the PHEV is improved by 4.27%; according to the upper-layer constraint control based on engine start-stop optimization, the start-stop frequency of the engine is reduced by 24% under the condition that the PHEV fuel economy influence is small, and the start-stop frequency of the engine is effectively reduced.
本发明公开了一种基于真实路况信息的自适应ECMS能量管理策略,以双轴并联式构型的PHEV车辆为研究对象,包括整车建模、ECMS问题的构建、修正ECMS约束SOC轨迹、等效因子自适应、基于城市实际驾驶路况信息对SOC全局规划、基于发动机启停优化上层约束控制、搭建控制策略模型以及结果仿真分析等环节。结果表明,与CD‑CS策略相比PHEV的燃油经济性提高了7.85%,与Time‑AECMS和Distance‑AECMS两种策略相比分别提高6.44%和4.27%;所提基于发动机启停优化的上层约束控制在PHEV燃油经济性影响很小的情况下使发动机启停次数降低减少24%,有效降低发动机启停次数。
