双行星混联式混合动力系统瞬时最优能量管理策略研究

Study on Instantaneous Optimal Energy Management Strategy for Dual Planetary Hybrid System

传统的基于发动机最优的控制策略目前只能使得发动机的效率达到最佳,它没有优化双行星混合能源系统的整体的效率。因此来说能源节约的效果一般。为了使车辆在不同车速下都能保持较高的效率,此文将探讨瞬时最优的能量控制的方式,通过探寻全车速下都能保持较高效率的点,以此减少燃油消耗,提高其燃油经济性。

The traditional control strategy based on the optimal engine can only achieve the best efficiency of the engine,b ut it does not optimize the overall efficiency of the two-planet hybrid energy system.So the energy savings are modest.In o rder to maintain high efficiency of vehicles at different speeds,this paper will explore the instantaneous optimal energy con trol mode and explore the point where high efficiency can be maintained at full speeds,so as to reduce fuel consumption an d improve fuel economy.
