A complete architecture for commercial vehicles
The evolution of the truck is progressively transforming electronic architectures, embedded systems and associated services. ACTIA operates across the entire value chain, with solutions covering computing, ECUs, energy management, connectivity, vehicle interfaces, diagnostics and connected services.
This approach addresses different levels of maturity and different architecture roadmaps, from conventional electronic architectures to more centralized and zonal architectures designed for the Software Defined Vehicle.
ACTIA does not promote a single architecture model. Its teams adapt electronic and software building blocks to the specific constraints of each program, the vehicle’s functional complexity and the technology roadmap selected by the manufacturer.

Truck solutions and SDV architectures
ACTIA covers centralized architectures including HPC modules and zone controllers, distributed architectures including cab and chassis ECUs, power conversion, embedded connectivity, vehicle interfaces for diagnostics, connected fleet services and lifecycle support.
HPC enables functions to be centralized, complexity and wiring to be reduced, architecture modularity to be improved and the transition towards software-defined vehicles to be prepared. This is particularly important for next-generation architectures.
ACTIA ECUs control and execute truck electronic functions, particularly for cab and chassis systems: access, lighting, driveline, bodybuilder interface or suspension. They are an essential building block of distributed architectures and can evolve with vehicle requirements.
Zone controllers follow a different architectural approach: they make it possible to group and locally manage the electronic functions of a vehicle zone, reducing wiring complexity and the number of distributed ECUs. They are therefore a key building block in the transition towards more centralized and zonal architectures.
ACTIA masters these different generations of architectures and provides solutions enabling manufacturers to progressively evolve their vehicles from distributed architectures towards centralized and zonal architectures, without breaking away from existing systems.
