[Abstract]:With the energy saving, environmental protection concept has gradually been widely recognized, the development and research of new energy vehicles are more and more extensive and in-depth by the major automobile manufacturers and research institutions. Hybrid electric vehicle (HEV), pure electric vehicle (EV) and fuel cell vehicle (FCEV), as representative energy-saving and environmental-friendly vehicles, have become the focus of energy-saving and environmental-friendly vehicles. Hybrid electric vehicle is considered to be the most effective and feasible way to realize the industrialization of energy-saving and environmental-friendly vehicle at present. In this paper, the velocity-coupled hybrid power system of single motor planetary train coupling mechanism is taken as the research object, and the main research is as follows: (1) the structure layout diagram of the whole vehicle is set up, and the connection diagram of the key components is established; And the modeling of the key components is studied. The driving power model, engine model and ISG motor model are established by combining the experimental modeling method with the theoretical modeling method, and the driving power model, the engine model and the motor model of the whole vehicle are established by combining the experimental modeling method with the theoretical modeling method. Battery model and planetary row dynamics model. It lays a solid foundation for the next step of vehicle economy research. (2) the characteristics of ISG hybrid drive system with planetary row are analyzed, and the working mode of the system is analyzed. Based on the equivalent fuel consumption method, the instantaneous optimal energy management strategy is established. The equivalent fuel consumption SOC correction coefficient and the average expected regenerative braking power are introduced to correct the equivalent fuel consumption of the battery. In order to improve the accuracy of the instantaneous optimization energy management strategy. Using the dynamic programming method, the engine throttle opening and AMT gear are used as control variables, the engine speed and battery SOC as state variables, and the minimum fuel consumption of the whole cycle engine as the objective function. A dynamic programming algorithm with battery SOC maintaining balance and limiting frequent shift as an additional cost function. 4 based on matlab/simulink simulation platform, the fuel economy simulation analysis of instantaneous optimization energy management strategy and global optimization energy management strategy under multi-cycle conditions is carried out. In order to verify the effectiveness of the energy management strategy and the advantages of the ISG hybrid power vehicle in fuel economy compared with the traditional vehicle. At present, the major automobile companies in the world have applied for patents to protect their hybrid vehicle energy management strategies. The energy management strategy of hybrid power system with independent intellectual property rights is developed to avoid foreign patents and promote the development of new energy automobile technology and industry in China.
