A Lean Automotive E/E-System Design Approach with Integrated Requirements Management Capability

Replacing former pure mechanical functionalities by mecha-tronics-based solutions, introducing new propulsion technologies, and connecting cars to their environment are only a few reasons for the still growing E/E-System complexity at modern passenger cars. Smart methodologies and processes are necessary during the development life cycle to master the related challenges successfully. In this paper, a lean approach for a model-based domain-specific E/E-System architectural design is presented. Furthermore, an integrated requirements management methodology is shown, satisfying the needs for a full traceability between the requirements and design artifacts. The novel model-based language allows domain experts, with limited knowledge of the de-facto system design standard SysML, to describe the mechatronics-based system easily and unambiguously. The lean tool chain orchestration makes the presented approach, especially but not limited to, interesting for small project teams.
