Efficiently mastering the complexity of electrified powertrains by simultaneously meeting all functional and performance targets requires a highly integrated development approach. The present paper provides an overview of the simulation framework elaborated in the project VISION-xEV for supporting digital development to enable faster deployment of electrified/hybrid vehicles on the market. The research and innovation activities of VISION-xEV comprised the development of fast high-fidelity e-component models including the related parameterization workflows and consistent methodologies for virtual component and system integration. The methods resulting from VISION-xEV facilitate the increased utilization of virtual prototyping on component, subsystem and powertrain/vehicle level for supporting the efficient and effective development of all kinds of future electrified/hybrid vehicles.
