Powertrain Simulation Research of Coaxial Series-Parallel Hybrid Electric Bus

Abstract

In order to know the vehicle performance of coaxial series-parallel hybrid electric bus, on the basis of the analysis of the powertrain’s structure and operation mode, the control strategy is made, the simulation system is introduced by the secondary development of Advisor, the simulation result is analyzed and used. Through the analysis of vehicle dynamic performance, fuel economy, SOC value change of super capacitance, and the torque relations of main components, it is known that coaxial series-parallel hybrid electric bus can satisfy the requirements of the city bus’ working condition, and the operation relations between the power components can be mastered, which provides the technical support for the coaxial series-parallel hybrid electric vehicle development.
