A foward-facing hybrid vehicle simulation tool based on multi-physics lumped circuit approach

In this paper it is described a research project concerning the derivation and the development of a novel foward-facing hybrid vehicle simulation tool based on Multiphysics lumped circuit approach. Sub-components are modelled as multi-port systems. Each port is characterized by means of an intensive and an extensive quantity complementary in power. This approach allow to model the mutual influence of the interconnection among blocks resulting in a more accurate simulation. A variational Lagrangian approach is used to derive analitical models. Equations are interpretated from a circuital point of view. The resulting circuit is then implemented and tested using the SimScape toolbox available in Matlab/Simulink environment.
