Abstract: With the introduction of a series of policies to support the development of new energy vehicles, the main development direction of China's automobile industry is green development and innovation-driven, among which the hybrid vehicle power system is one of the key technologies studied at this stage. In this paper, a new hybrid power system with double planetary rows is introduced, its structure and working mode are introduced, and the power distribution of the hybrid power system is analyzed by means of the combination of block diagram and lever method. In order to improve the efficiency of the hybrid power system, the influence law of double planetary parameters on the power flow is studied by MATLAB modeling.
