Summary

The increasing global requirements regarding emission limits, especially CO₂ emissions, pose future challenges in vehicle development and in particular for powertrain development. The consequence is an increasing degree of electrification resulting in a simultaneous increase in powertrain complexity. Furthermore, changing mobility demands and market specific requirements are broadening the multidimensional solution space of possible technologies. This poses complex powertrain portfolio challenges for the OEMs, combined with a high development risk. The complexity and risk can be reduced by the digitalization of development processes. The research project by Audi AG and the Institute of Automotive Engineering of the Braunschweig University of Technology addresses this area of conflict. The aim is to identify new promising hybrid powertrain concepts. Therefore a tool chain for the identification and conceptual dimensioning of electrified powertrains for premium vehicles is being developed. The tool chain consists of five different computer tools, which represent the necessary steps for the identification, dimensioning, evaluation and optimization of electrified powertrains. The virtual, methodical and reproducible approach can contribute to the fulfilment of customer and product requirements, while reducing development time and cost.
