Energy management control strategy for plug-in hybrid electric vehicle

Aiming at the high requirement in the economy and power performance for the energy management of plug-in hybrid electric vehicle, an energy management control strategy for the plug-in hybrid electric vehicle was proposed. The overall scheme for the vehicle energy management strategy was designed, and the effect of driven distance on the fuel economy of plug-in hybrid electric vehicle was analyzed. Meanwhile, the auxiliary energy management control strategy with the adaptive driven distance was designed. The results show that the proposed vehicle energy management strategy can reasonably select the most suitable operating mode according to the road and vehicle information, and can distribute the electric energy charged from the grid more rationally and improve the fuel economy of vehicle.
