Abstract
The purpose of this study is to analyze the system characteristic of coupling multiple power unit in hybrid power trains and to evaluate the system efficiency of varies kind of powertrains. The goal is to identify the proper coupling type to enhance system efficiency. This study starts from introducing the conceptual hybrid system and its operation mode. Power unit, system loading and mechanical coupler in hybrid power train are analysis in detail. The power trains are then sort by the speed and torque relation between power unit and system loading. Using ADVISOR as the simulation tool, this research compare different kinds of hybrid power trains by their engine efficiency, transmission efficiency and fuel efficiency. Finally, a novel hybrid system is evaluated in this study. The novel hybrid system is simulated in ADVISOR and the system unit, design variable, control strategy is assigned. The novel hybrid system is compare with Toyota Hybrid System to fully understand the potential of this system. In this research, the characteristic of hybrid system is analyzed. The result could be a considerable consultation for design hybrid power trains.
