Parameter Matching and Simulation of Plug-in Hybrid Electric Bus

The global energy crisis and environmental crisis have made countries all over the world attach great importance to the work of energy conservation and emission reduction. The automobile industry, as an important industry of energy consumption and exhaust emission, should be at the forefront of energy conservation and emission reduction. In this paper, a plug-in hybrid electric bus is taken as the research object. On the basis of the dynamic performance index, the key components such as driving motor, engine- generator, battery and transmission system transmission ratio are matched. Then the economic control strategy of the whole vehicle is put forward, and the vehicle simulation model is established by using MATLAB/Simulink and AVL Cruise software. The performance simulation is carried out to achieve the goal of economic improvement.
