SysML for embedded automotive systems: SysCARS methodology

Abstract

: This paper gives an overview of the years of Valeo experience in deploying a Model Based System Engineering (MBSE) approach for mechatronic automotive embedded systems and products. The different stages are described initial studies, language and tool benchmarking up to the last returns of experience on industrial projects. Particular emphasis is put on describing the SysCARS methodology which gives, not only a precise mapping of System Engineering work items to SysML artefacts, but also the sequence of modeling activities to be performed. It is shown how the SySCARS methodology has been implemented as a SysML profile, based on a powerful “workflow driven” mechanism, which helps the user during the modeling process. Finally it is presented how interoperability is ensured with the tools already in place for requirements management and control design.
