Abstract
Automotive researchers are making efforts to introduce a control strategy for an hybrid electric vehicle (HEV) using an electric variable transmission (EVT). A global modeling for an EVT equipped HEV is needed to develop the control strategy for such applications. Energetic macroscopic representation (EMR) is used to model such a complex system that has a graphical tool suitable for modeling and control of complex electromechanical systems. The interconnection of subsystems is organized according to the physical causality using an EMR. A split EVT is used to analyze its operation modes and control strategy to simplify the problem of global modeling of the EVT-equipped HEV. EMR is used to organize the interconnection of subsystems including EVT, ICE, and battery. It has been demonstrated that the key to HEV control is the immediate computation, management, and distribution of the power flows from different energy sources to achieve the control objectives.
