Enhancing MBSE for E/E architecture design to drive key software capabilities

Czas czytania: 25 min

Vehicles in all sectors are growing in complexity as OEMs develop sophisticated platforms with increasing levels of automation and connectivity, driving a rapid expansion in the size and complexity of vehicle architectures. The complexity of these modern E/E architectures makes them extremely challenging to design and verify using traditional, labor-intensive procedures that are in place at many manufacturers. In addition, maintaining traceability of vehicle requirements, functions, and implementations through each vehicle abstraction becomes nearly impossible.

In this white paper, discover how model-based systems engineering (MBSE), with an advanced portfolio of engineering software solutions, can provide these crucial capabilities for developing the increasingly sophisticated E/E architectures of modern cars and commercial vehicles.

Providing robust data continuity with MBSE driven E/E development

Automotive and commercial vehicle OEMs must evolve their architectural design processes to leverage MBSE and the digital thread to cope with this growing complexity. Today's E/E system engineering solutions help companies implement MBSE by providing robust data continuity and advanced automation capabilities. With these solutions, engineers can use existing functional models to generate vehicle architectures and more detailed system designs, continuously building on data from upstream processes to ensure traceability from functions to implementations and actual components or systems. These solutions also provide closed-loop verification and optimization of architectures and system designs to improve vehicle performance at the architecture level.

Continuous digital thread tracks vehicle system behavior throughout development

As vehicles become more automated, the traceability provided by an MBSE flow with advanced E/E engineering tools will be crucial to demonstrate regulatory compliance and the safety of a vehicle platform. A continuous digital thread throughout vehicle development and manufacturing will enable the generation of accurate documentation directly from vehicle design data. This digital thread can also track test results and show that vehicle systems behave as expected, becoming an imperative capability as OEMs are asked to demonstrate the safety and reliability of their vehicle systems before, during, and after production.
