摘　　要：应用动态规划全局优化算法,针对并联式Plug-in混合动力汽车在不同行驶里程下的能量管理策略进行了全局优化研究。结果表明:车辆的行驶里程小于55km时应使用电动机为主的能量管理策略,当车辆的行驶里程大于55km时应使用发动机为主的能量管理策略;在动态规划最优控制下,车辆行驶里程为55km时整车经济性能最佳,行驶里程小于110km时整车平均等价油耗为2.7L/100km,相对于原型车经济性提高了近58%。By using DP which is a kind of global optimization algorithm, an energy management control strategy for a parallel PHEV on different charging depleting range（CDR） had been studied. The results show that motor--dominant control strategy should be applied to the PHEV when CDR is less than 55km,and engine--dominant control strategy should be used when CDR is more than 55km. With optimal control strategies from DP, the best economic performance can be obtained as CDR is 55km;PHEV average equivalence fuel consumption can be reduced to 2.7L/100km which is 58% lower than that of prototype vehicle.
