Control strategy and simulation technology of Integrated Starter/Generator Hybrid Electric Vehicle

The paper studies control strategy and simulation technology of Hybrid Electric Vehicle (HEV) based on Xiali 7100 prototype. Firstly, the frame structure of parallel Integrated Starter/Generator (ISG) mild HEV is designed and parameters of main components are identified. Then a logical gateway based instantaneous optimization control strategy is proposed for the system after mode analysis. Finally, the fuel consumption evaluated module is built under MATLAB/Simulink simulation environment. Different typical city bus circles are selected for analysis and results indicate that the proposed control strategy can improve fuel economy and lower emissions.
