As a novel series-parallel power train, electric variable transmission (EVT) has attracted increased interests in recent years because of its high level integration and the advantages in improving fuel economy and reducing emissions. This paper will briefly introduce this novel power train and put more emphasis on its applications in hybrid electric vehicle (HEV) including modeling, simulation and experimental study. The work is helpful to design EVT, analyze the power flows of an EVT based HEV, and make the control strategy. Energetic Macroscopic Representation (EMR) is used in the global modeling for the EVT based HEV, and a control scheme is deduced from EMR models using specific inversion rules.
