Abstract

In their continuous quest to improve the user experience, many manufacturing companies embed additional software in their products to introduce more intelligence and make them smarter. It is happening in the automotive, nuclear, space, aeronautics and other industries. While this means a significant competitive advantage for these companies, it also comes out with a higher complexity, in terms of design, product architecture or organization. To manage this type of complexity, companies use System Engineering, an interdisciplinary scientific approach aiming at formalizing and understanding the design and validation process of complex systems. Its adoption by the industry is accelerated by the development of MBSE methodologies and tools (model-based system engineering). They offer a way to work with visual representations of the system (model) to be developed rather than traditionally using multiple documents, to avoid interpretations, errors, outdated data? However when it comes to this process is missing a point. It takes little or no account of the simulations, fully part of the design and validation process of complex systems today. With this presentation, we will explain how DPS worked, in collaboration with the IRT (Technical Research Institute), on the development of the braking system of an autonomous electric vehicle (Renault?s Zoe) by a multidisciplinary team. To achieve this, we used and took advantage of the MBSE approach as well as KARREN, a in-house software. KARREN complements MBSE tools in a simple way, with a sober interface and clear concepts. It acts in many ways: ? Absorbing and synchronizing the needed data from a MBSE software or simply translating SysML objects. ? Creating connections between simulations and system engineering models very easily ? Building a robust collaborative space including requirements and characteristic product parameters ? Providing indicators to help the decision makers We will demonstrate how associating KARREN and MBSE can make products more efficient and cost-effective.
