摘要/Abstract

摘要： 从实际应用角度出发，针对插电式混合动力汽车提出了一种次优能量管理策略，借助随机动态规划获得了最优的挡位与功率分配，提出了算法内部约束与外部修正相结合的方法来解决最优策略在实际应用中可能出现的频繁升降挡问题，并采用瞬时优化算法解决换挡过程中的最优功率分配问题。研究结果表明：与传统的瞬时优化控制策略相比，所提策略的燃油经济性有显著的提升效果。

关键词: 插电式混合动力汽车, 次优能量管理策略, 随机动态规划, 瞬时优化

Abstract:

From the perspectives of practical applications, a sub-optimal energy management strategy was proposed for plug-in hybrid electric vehicles. The optimal gear positions and power distribution were obtained by using SDP. The method which combined internal constraints and external correction was proposed to solve the problems of frequent gearshift in the actual applications. And the instantaneous optimization algorithm was adopted to solve the optimal power distribution in the gear shifting processes. The research results show that compared with the traditional instantaneous optimization control strategy, the fuel economy of theproposed strategy is significantly improved.

Key words: plug-in hybrid electric vehicle, sub-optimal energy management strategy, stochastic dynamic programming（SDP）, instantaneous optimization
