Expert consulting for a next-generation vehicle network

The electrical and electronic architecture of a commercial vehicle is being rebuilt. As trucks and buses take on more software, more connectivity and more autonomy, the in-vehicle network that carries it all is moving to a new generation — higher bandwidth, service-oriented communication, and the diagnostics needed to develop, manufacture and maintain it. Getting that communication layer right is foundational: everything above it depends on a network that is fast, deterministic and diagnosable.

Scania is one of the world's leading makers of heavy trucks, buses and industrial and marine engines — a manufacturer with a long engineering tradition and a clear stake in getting the next generation of vehicle architecture right.

Moving to a new generation of vehicle-network communication is not a single component change; it touches architecture, protocols and the diagnostics that have to work across development, production and the aftermarket. It calls for deep, specific expertise in vehicle-network communication and diagnostics — the kind that is hard to staff internally for a one-time architectural shift.

Scania brought in Diadrom for expert consulting on the new generation of vehicle-network communication technology and the diagnostics around it. It is the model Diadrom is built for: specific, senior diagnostics and communication expertise, brought into a customer's own programme exactly where the hard problems are — the same automotive diagnostics rigour Diadrom has carried since 1999, applied here to heavy commercial vehicles.

The engagement extends Diadrom's diagnostics and communication expertise beyond passenger cars into heavy commercial vehicles, at the layer that matters most for a software-defined future: how the vehicle communicates. It is the same discipline — deep, specific, senior expertise in vehicle-network communication and diagnostics — that Diadrom brings across automotive and defence.

As commercial vehicles become more software-defined and more connected, the next-generation network underneath them only grows in importance. The lesson generalises across heavy vehicles: treat vehicle-network communication and its diagnostics as a foundational, expertise-led investment — not a late-stage integration detail.
