Developing Mobility Architectures, E/E and Software Systems for the Transportation and Mobility Industry

Undoubtedly, the transportation and mobility industry is experiencing impressive innovation and dramatic change today. Sustainability and safety spur the development of new-to-the-world electric drives, groundbreaking battery platforms, and novel assisted and autonomous systems. Many OEMs and suppliers are turning to systems engineering as a framework for it all.

Model-based systems engineering (MBSE) approaches have been vital to developing better architectures for mobility solutions. Yet, there are flaws. Systems engineers develop a great system and then turn it over to integrated or domain-specific teams for detailed design. Too often, that architecture becomes a static, unchanging thing because systems engineers and detailed design engineers use different software solutions and file formats. Those systems’ definitions often need to be more consistent or support exploratory efforts needed in detailed design.

Developing Mobility Architectures on the 3DEXPERIENCE Platform

Per Dassault Systèmes, Vice President of Transportation and Mobility Laurence Montanari and Director of Transportation and Mobility Services Frederic Merceron, the capabilities of the 3DEXPERIENCE platform address those fundamental flaws. This solution allows systems engineers to develop architectures and share them with detailed design teams. Everyone sees others’ changes or collaborative comments because the definition lives on the cloud-based 3DEXPERIENCE platform. It is not transformed or translated into different definitions or files. That living, digital definition allows everyone to stay on the same page throughout the development cycle and beyond. Detailed design engineers could negotiate with their peers or systems engineers to trade off or change technical budgets, like weight or cost.

What’s my take?

MBSE has delivered value to OEMs and suppliers. Our research has shown that. Yet, the inherent shortcomings of file-based solutions have limited that value. This approach fundamentally addresses that issue. With so many teams pressing the boundaries of electric vehicle development, it is easy to lose cohesion with other engineering teams. That can undermine the whole innovative effort. Working on a cloud-based MBSE solution, alongside all the different design, simulation, manufacturing, and other platform capabilities, close that gap. Engineers can genuinely collaborate and innovate. Leveraging the 3DEXPERIENCE platform offers differentiation for those looking to use systems engineering to do

Developing E/E and Software Systems in the Transportation and Mobility Industry

Is the 3DEXPERIENCE platform ready for developing electrical/electronics (E/E) and software systems in the transportation and mobility industry? That’s been a critical question on my mind for some time.

Dassault Systèmes has long provided solutions that supported the development of mechanical hardware and the overall lifecycle of a product. But things are changing fast today in the automotive industry. Software and electronics are the main value drivers in mobility solutions, managing the life of battery systems and delivering assisted and autonomous driving capabilities. Our research shows that this complexity is high and will continue to rise dramatically in the next two years.

Technical conversations with Montanari and Merceron revealed quite a bit regarding E/E systems development support. In the 3DEXPERIENCE platform, engineers can allocate functions to electronic hardware, aspects of the electrical system, or software components. Then, these engineers can also set up and run simulations around compute usage, network bandwidth consumption, and software as part of a control system. Engineers can then iterate, exploring different architectures and moving functions around. They get feedback quickly, supporting short iteration loops.

Another advantage of leveraging the platform lies in using a single source of truth for the E/E system. Digital models, designs, and artifacts are not split into electronics, electrical, and software domain-specific software systems where their definitions can diverge. They all live on the platform where they stay in sync. This powers digital continuity, so no one has to manually track changes across multiple software solutions, and traceability, so everyone can understand what change led to other impacts.

What’s My Take?

E/E systems development is a huge challenge today. Engineers need solutions to let them iterate faster, understand the implications of their decisions, and collaborate tightly with engineers from other domains and teams. The 3DEXPERIENCE platform provides capabilities to address all these needs and more. This part of the platform may not get a lot of fanfare or attention, but it is a robust, innovative solution set.
