The Control And Simulation Of Dynamic System For Amt Hybrid Electric Bus

The parallel hybrid system, due to dynamic coupling and power switching has not been completely resolved, making vehicles in th actual operational process unstable performance and unsatisfactory economy. Theoretically AMT (automatic mechanical transmission) can solve the above problems, but which also increases the difficulty of vehicle control.In this paper,based on the AMT’s parallel hybrid system, the shifting logic and power allocation strategy, design, and through ADIVSOR software simulation, the results are summarized as follows:1) This paper have analyzed the layout structure and control structure of the AMT’s parallel hybrid bus power system and parts composition of the control system.It have also studied depely in the key components assembly VCU(Vehicle Controller Unit) and the AMT system, to lay the foundation for the modeling of the various components of the subsequent chapters.2) This article describes the development process of the vehicle simulation software ADVISOR in MATLAB. It is based on an AMT parallel hybrid electric bus prototype, some of its main components is modeled based on ADVISOR platform.3) It simple to introduce the shifting logic and power allocation strategy.Then it have designed a brief introduction of the shifting logic and power allocation strategy under the different operating conditions of vehicles operating mode. And finally to establish the model of the ADVISOR environment control..4) First of all, it is established AMT parallel hybrid bus model under the environment of MATLAB/on ADVISOR. For examining the logic of the applicability in the models and verifing the subject design, it have simulated and analyzed the model dynamics and the main components in the two different typical conditions of performance.
