Based on the introduction of the mechanical structure and working principle of the new compound power-split hybrid electric vehicle, this paper studies the minimum equivalent fuel consumption energy management control strategy based on the minimum principle and builds the model and simulation environment through Simulink. Compared with the traditional internal combustion engine prototype vehicle, the fuel consumption per 100 kilometers under the NEDC cycle condition has significantly improved the fuel economy of the whole vehicle. The results show that the optimal control strategy formulated in this paper can realize the working mode of hybrid electric vehicles and achieve better fuel saving and control effects.
