Matching Selection and Simulation Design of ISG Hybrid Power System

Hybrid electric vehicle(HEV)is a combination of traditional fuel oil vehicle and pure electric vehicle(EV). It has the advantages of good power performance and high cruising range of traditional vehicle, as well as the characteristics of energy saving and low emission of pure electric vehicle. This paper analyzes the choice of engine and motor coaxial parallel connection for power mixing. According to the structure characteristics, the parameters of the reference vehicle are matched and designed, and then suitable components such as engine, ISG motor set and battery are selected. Suitable control strategy is formulated according to the need, and vehicle performance simulation model is established based on MATLAB software platform. The simulation results show that all the indexes of the vehicle meet the target requirements.
