Mode Integration Algorithm Based Plug-In Hybrid Electric Vehicle Energy Management Strategy Research

One of the reasons which cause poor fuel consumption of plug-in hybrid electric vehicle (PHEV) is that working modes switch frequently. In order to solve this problem, the single-shaft PHEV and fuel consumption are regarded as research object and research goal, respectively. The method which integrated many modes into one module is used to improve fuel economy of PHEV. And this paper proposed mode integration algorithm based PHEV energy management strategy. Simulation results indicate that this paper proposed mode integration algorithm based energy management strategy can improve fuel economy largely and it's meaningful for researching and development of PHEV.
