提出了一种基于最优控制的并联混合动力汽车能量管理策略。这种策略不仅试图在将电池的充电状态保持在合理范围内的同时最小化燃料消耗，还寻求最小化电池的磨损并延长其寿命。本文的重点是理解在这种情况下由庞特里亚金最小原理（PMP）提供的最优控制解。仿真结果表明，该控制算法能够在最小的燃油经济性损失的情况下，通过降低电池运行严重系数来减少电池磨损。当环境和驾驶条件特别恶劣时，这种策略的好处尤其明显。
This paper presents an optimal control-based energy management strategy for a parallel hybrid electric vehicle (HEV). Not only does this strategy try to minimize fuel consumption while maintaining the state of charge of the battery within reasonable bounds, it also seeks to minimize wear of the battery and extend its life. This paper focuses on understanding the optimal control solution offered by Pontryagin's minimum principle (PMP) in this context. Simulation-based results are presented and analyzed, which show that the control algorithm is able to reduce battery wear by decreasing battery operating severity factor with minimal fuel economy penalty. The benefit of this strategy is especially evident when ambient and driving conditions are especially severe.
