ACTIA, Partner in the Transformation of Software-Defined Truck Architectures

The truck is no longer a sum of components. It is a platform designed to evolve long after it leaves the factory, driven by software—not just hardware.
ACTIA operates precisely at this intersection: on one side, a long-standing expertise in tier-one electronic architectures; on the other, a true software factory dedicated to diagnostics and vehicle data. This dual expertise enables ACTIA to support manufacturers far beyond component supply, from architecture design through fleet operation, across the entire vehicle lifecycle.
In a market where manufacturers and fleet operators are looking for partners able to master hardware, software, connectivity and industrialization as an integrated whole, ACTIA already has the capabilities in place.

A Transforming Market That Is Redefining the Role of Partners

The industrial vehicle market is now entering a period of profound transformation. Architectures are becoming increasingly centralized, software is becoming the primary driver of value creation, and vehicles are evolving into platforms capable of integrating new features over time.
The direct consequence for manufacturers and fleet operators is that they are no longer looking only for component suppliers, but for partners capable of designing robust architectures, integrating complex systems, leveraging vehicle data and deploying solutions at scale.
The shift toward software-defined architectures is fundamentally reshaping the value chain. This transition is driven by three major developments:

the increasing separation between hardware and software
the centralization of electronic architectures around platforms
the development of scalable connected services.

In this new model, OEMs define the platforms, but can no longer develop everything themselves. They rely on an ecosystem of partners able to provide, integrate and industrialize technology building blocks. The players that succeed are those that can:

master hardware and software,
integrate complex systems,
deploy at scale.

In practice, this translates into very concrete challenges for manufacturers:

managing the growing complexity of electronic and software architectures
ensuring vehicle availability and operational performance
securing software updates and OTA upgrades
meeting safety and cybersecurity requirements.

This is precisely where ACTIA positions itself.

From a Component-Based Approach to a Platform-Based Approach

In the Software Defined Vehicle era, the truck market is shifting from a component-based approach to a platform-based one. OEMs are now structuring their vehicles around more centralized architectures, progressively decoupling software and hardware, and looking for partners able to master electronic building blocks, critical software layers and industrialization as a whole. In this context, value is shifting toward players capable of integrating, evolving and deploying these complex systems over time.
Industry analyses point in the same direction: the Software Defined Vehicle (SDV) market is expected to grow significantly over the coming years, with a substantial share of value available to suppliers able to reposition themselves within this new value chain.

Why Flexibility Is Becoming Critical

In a market marked by significant technological uncertainty, manufacturers are constantly balancing the rapid integration of new features with the need to control complexity. The challenge is no longer to lock in a definitive choice too early, but to design architectures that can evolve without having to rebuild everything. This is particularly true in four areas: centralized computing, new software interfaces, next-generation diagnostics and connected services. OEMs need robust foundations, but also architectures that remain open to evolution and can integrate new building blocks without calling the entire system into question.

ACTIA’s New Positioning

Beyond its historical expertise in embedded electronics, ACTIA is now positioning itself as a global vehicle architecture player, with three capabilities that have become essential in the SDV era:

providing the electronic foundation for new architectures,
making these systems operational through critical software layers, and
supporting their large-scale industrialization.

In this new value chain, ACTIA is no longer limited to the role of a Tier 1 supplier. The company acts as a transformation partner, able to connect hardware, software and services within a coherent approach serving both vehicle architecture and its real-world implementation.

This evolution directly addresses market expectations. The players that succeed in the SDV era are those that master hardware and software, can integrate complex systems and have the industrialization capabilities needed to move from concept to deployment.

In software-defined truck architectures, diagnostics (known as SOVD) are no longer simply an after-sales tool: they are a foundational capability that supports system consistency, ensures maintainability and enables evolution throughout the vehicle lifecycle.

Three Pillars to Support New Truck Architectures

To address the transformation of the truck market, ACTIA structures its approach around three complementary pillars that together address the architecture, operation and deployment of new software-defined vehicles.

Hardware platform

In a market where architectures are becoming increasingly centralized, hardware remains a strategic pillar. The centralization of functions around more powerful computing units, the evolution of power systems and growing connectivity requirements increase the need for robust embedded platforms designed to evolve over time.

ACTIA is a key partner in the truck’s electronic transformation. Zonal ECUs, power electronics, telematics, HPC platforms: we master the technology building blocks that enable the transition from today’s distributed architectures to tomorrow’s centralized, software-defined architectures. By combining electrical architecture, connectivity and computing power, ACTIA supports manufacturers in designing trucks that are smarter, more connected and ready for future developments.

Diagnostics & SOVD (Service-Oriented Vehicle Diagnostics)

In SDV architectures, diagnostics can no longer be viewed as a simple after-sales tool. It is a strategic software layer connected to the vehicle, the workshop and the cloud. The SOVD approach illustrates this shift: simplifying access to vehicle functions, making developments reusable and opening up new services around vehicle data.

ACTIA offers a comprehensive diagnostics portfolio based on a robust software core and the integration of emerging standards. This approach enables diagnostics to be deployed consistently across the entire value chain: in the workshop, in the cloud and embedded in the vehicle. Diagnostics thus become a key lever for system control, service continuity and architectural scalability, directly contributing to vehicle availability and fleet maintenance optimization through better use of diagnostic data.
