摘　　要：以提高一款新型混联式混合动力客车燃油经济性为目的,以中国城市典型循环工况为例采用动态规划算法进行离线全局优化,针对运用动态规划(DP)算法的全局优化控制策略不能直接应用于实时控制的问题,基于DP的全局优化结果不仅提取了混联式混合动力系统的模式切换规则而且制定了一种功率均衡控制策略。应用simulink仿真平台建立功率均衡控制策略整车前向仿真模型,其结果和DP全局优化进行比较表明:所制定的功率均衡控制策略为新型混联式混合动力客车实时控制提供一种方案并且能够有效提高其燃油经济性。In order to advance fuel economy of a novel series-parallel hybrid electric bus （SPHEB）, a power balancing （PB） control strategy and the control rule of mode switch both were derived from the results of dynamic programming. The DP was used to global optimization based on the typical Chinese transit bus driving cycle, and to solve the problem that the global optimization control strategy based on algorithm of DP couldn＇t be implemented in the real time control. To validate the proposed strategy effective and reasonable, a forward model was built based on sirnulink, and the results comparing to the of DP demonstrate that the proposed strategy is an alternate approach for the real time control and improves the fuel economy effectively.
