Bond Graph Modeling of Series-Parallel Hybrid Electric Vehicle Power Train Dynamics

The bond graph method is used to model dynamics of various one-mode and two-mode series-parallel configurations of hybrid electric vehicle power trains. Proper handling of causalities results in minimum-realization models convenient for various simulation, analysis, and control design studies. The same, unified model structure can be used to describe the dynamics of all considered hybrid power trains. Several alternative variants of the power train dynamics model are also derived for various structures of driveline submodel.
