英文摘要：

In order to improve the design rationality of fuzzy energy management strategy for a hybrid electric vehicle（ HEV）,dynamic programming（ DP） algorithm is used for a global optimization on the performance of a speed coupling ISG HEV. Then by analyzing the control results of DP algorithm with design parameters extracted,the rule and strategy of fuzzy control are worked out and a corresponding fuzzy controller is designed. Finally a simulation model is set up based on Matlab / Simulink,and the simulation results with DP algorithm and fuzzy control strategy are compared. The results show that the fuzzy control strategy designed achieves the expected results and the design method is reasonable and effective.
