Requirements-based, early stage Architecture Performance Validation on a Brake System Use Case

Abstract

Automotive industry OEMs and suppliers are progressing their engineering processes and performance to the next maturity level gearing to digital thread solutions. Current challenges like continuous engineering, virtual certification, distributed development, consolidated virtual proving grounds, homologation, digital twin and operational applications, require well informed decision making in a comprehensive, reliable, traceable and customizable environment. In particular, in automotive domain, with widespread tight collaborative ecosystems between integrators and suppliers, the capability of tracing each decision and its underlying artifacts becomes a key value of an engineering platform. This paper will outline a middleware approach to reuse generated artifacts and their relationships in a federated engineering environment and applying Modelica simulation models as the key integrator between architectural decision making and subsequent development up to detailed 3D design. Based on an exemplary, automotive brake system setup, the benefits of integrated data and workflows from specification to virtual architecture exploration and design verification are highlighted to motivate their value towards a realization of continuous model-based systems engineering methodologies.
