In order to optimize the fuel economy of hybrid bus, and to improve the driving performance, a control strategy based on logic gate torque distribution is designed in this paper. A power system model including vehicle model, engine model, motor model, generator model, battery model and clutch model is established, on this basis, the driving torque distribution rule and the braking torque distribution rule are analyzed in detail. A control strategy for a coaxial parallel hybrid electric bus is designed. The correctness of the model and the effectiveness of the control strategy are verified by simulation. Finally, the simulation is carried out based on the working conditions, and the simulation results are in line with expectations. It verifies the validity of the model under the transient working mode, and has certain significance to the development of control strategy in the design process of hybrid electric vehicle.
