Research on logic control strategy for a series-parallel hybrid electric bus

The control strategy of hybrid electric bus decides the performance of the whole electric bus. In this paper, the structure and logic control based control strategy of a series-parallel hybrid electric bus were analysed. The corresponding simulation model and controller of the bus were developed. With co-simulation of AVL/CRUISE and MATLAB/Simulink, dynamic characteristics and the fuel consumption per 100km of the bus were obtained under the typical Chinese city traffic condition. The simulation results indicate that the primary parts can realize proper switch in different states, that the control strategy based on logic control can satisfy the performance requests of the whole vehicle.
