Bond Graph Modeling of a Planar Vehicle with Electric Traction Motors for Assisted Torque-Vectoring

Donghun Lee, Jonathan Loyola, and Donald Margolis

Powertrains for vehicles are transitioning from the internal combustion engine to electric motors. Electric motors have the ability to both output traction and generative braking torque. Furthermore, electric motor powertrains have a smaller size compared to the internal combustion engine powertrain. This opens up thepossibility of different configurations of powertrain layouts. This paper explores an electric vehicle model with motors on both the front and the rear axles. The planar vehicle model with varying motor torque distribution is simulated to validate its handling dynamics.
