混合动力汽车能量控制策略

针对串联、并联和混联3种类型的混合动力汽车驱动系统的不同结构特点，文章对3种类型混合动力汽车的能量控制策略分别进行了详细阐述，指出了未来混合动力汽车能量控制策略研究的发展方向。能量控制策略不仅要实现整车最佳的燃油经济性，而且还要兼顾发动机排放、蓄电池寿命及驾驶性能等多方面要求，并针对混合动力汽车各部件的特性和汽车的运行工况，使发动机、电动机、蓄电池和传动系统实现最佳匹配，兼顾上述各方面要求的优化控制策略的研究应是今后的研究重点。

Research on Energy Control Strategies of Hybrid Electric Vehicles

The different structural features of drive systems of series, parallel and series-parallel hybrid electric vehicles make it necessary to analyze the energy control strategies of the three types of hybrid electric vehicles in detail in this paper. The future development of energy control strategy of hybrid electric vehicles has been pointed out at last. The energy control strategies should not only ensure the complece vehicle＇s fuel economy, but also take into consideration the engine emission, battery and driving performance. What＇s more, in light of the parts features and driving conditions of the hybrid electric vehicle, we should pay close attention to how to realize the optimum match among engine, motor, battery and transmission system. The research on optimum control strategy mentioned above will be the hot topic.
