Designing a scalable network for Software defined vehicles
The move to software-defined vehicles is driven by the rapid growth of software-intensive functions—ADAS/AD, electrification control, and connected services—which require continuous updates, data-driven improvement, and faster feature velocity than hardware-centric architectures can support. As high-performance computing (HPC) capabilities advance, more vehicle functions can be consolidated onto fewer computing platforms. This architectural compression supports migrating edge-based software to centralized HPCs, enabling a more efficient, scalable in-vehicle network design that can support new capabilities for years to come. Domain vs zonal architecture in the modern in-vehicle network Two dominant architectural approaches have emerged. Domain Master architectures assign dedicated HPCs to individual technical domains, such as powertrain, body and chassis, and driver-assistance systems. This architecture is often effective for today's systems.However the cabling and networking of ...
