摘 要: 针对分路式并联混合动力四驱车给出了一种能量管理方案。为了优化发动机、电机及电池的工作效率 ,给出了基于模糊逻辑的能量管理策略。为了进一步提高整个系统的工作效率 ,鉴于用发动机和电机驱动时能量流向的不同 ,提出了发动机的启停线 ,使整车的动力性能、油耗和排放得到优化控制。经实际路试 。 In this paper, an energy management strategy is developed for parallel hybrid four wheel driving electric vehicles. A fuzzy logic based energy management strategy is used to optimize the operational efficiency of the engine, motor and batteries. To improve the efficiency of whole system and optimize the dynamic performance, the fuel economy and the emissions, a starting/stopping curve of engine is presented considering the different flow of energy in case of motor and engine respectively. The results of test show that the strategy can satisfy the performance index of the whole design.
