Abstract :
Along with the development of hybrid electric vehicle, dual-mode electro-mechanical transmission (EMT) as an innovative power-split transmission technology, is widely applied in heavy-load vehicles. In this paper, a dynamic model for a dual-mode EMT based hybrid electric vehicle is developed which consists of two electrically variable transmission (EVT) modes and provides a platform for performance analysis of vehicle components including electro- mechanical characteristics analysis. Due to drive condition of the powertrain system, the electro- mechanical characteristics of mode switch is evaluated by a simulation model which is designed based on MATLAB/Simulink, and the simulation results are comparatively analyzed. It is expected that the research contents of this paper can be served effectively as a basis for future research in the field of EMT.
