Holistic virtual testing and analysis of a concept hybrid electric vehicle model

In this paper, the development, integration, and analysis of a hybrid electric vehicle (HEV) using system level virtual testing will be presented. The work will discuss how a Modelica-based Parallel HEV powertrain model developed using MapleSim is integrated into IPG’s industrial vehicle modelling software tool, CarMaker, using the Functional Mockup Interface (FMI) standard; and how, using API commands, virtual testing and analysis was performed with Noesis’s optimisation tool, Optimus. The acausal modelling of the HEV powertrain was done using Modelica 3.2.1, allowing the flow of energy to be inferred from the operating characteristics and controller design. The multidomain model uses components from the electrical and mechanical libraries, including commercialised library components, from the MapleSim Driveline Component Library and the MapleSim Battery Component Library.
