This paper deals with the optimal control strategy design of the easier management (EM) dual-mode power-split device (PSD) in hybrid electric vehicles (HEV). The EM mechanism provides two modes of operation for the HEV based on the clutches performance. One mode is the input split mode and the other is the compound split mode. Dynamic programming (DP) method is used to find the optimal control strategy including the mode switching and the power split between the power sources while providing the charge sustaining condition. Simulation results show significant improvements of the fuel consumption in comparison to the Toyota Hybrid System (THS), which is a well-known industrialized PSD, and in comparison to the rule-based methods.
