AX400 and AX250 are part of U-Control’s AX Platforms, bringing system-level consistency to HMI design across off-highway machines.

For many OEMs, HMI development still evolves machine by machine.
Different interfaces. Different logic. Different implementations.
It works. Until complexity starts to scale.

As product ranges expand, this approach generates fragmentation across engineering, user experience and the lifecycle of the machine.

This is a pattern consistently observed across OEM projects: the issue is not the interface itself, but the lack of a system-level structure behind it.

AX Platforms: a system, not just a product

AX Platforms are developed by U-Control to address this gap.

At their core, AX400 and AX250 are armrest-based HMI platforms designed for off-highway machines: integrating controls, interface logic and system interaction into a configurable environment.

AX400 is designed for machines requiring extended control and advanced interaction.

AX250 brings the same design principles into a more compact architecture, engineered for applications where space and integration constraints play a defining role.

They are part of a unified platform designed to bring coherence and continuity across machines.

The objective is not uniformity, but to define a shared system architecture that can be adapted while maintaining a consistent logic.

This allows OEMs to move away from isolated design decisions toward a structured approach that scales across the product range.

This applies across applications from agriculture and construction to logistics, transportation and municipal vehicles, where machines evolve within structured product families defined by specific constraints.

Where the difference is made

A platform is only as effective as how it is developed.

AX Platforms are designed by U-Control with a system integration approach, meaning the interface is engineered in relation to the machine’s electronic architecture, embedded software logic and control systems.

This includes the integration of hardware, software and control logic within a unified system.

This allows the HMI to be aligned from the beginning with how the machine operates, rather than being adapted at a later stage.

In this perspective, the armrest becomes part of a broader system — an interface developed in coherence with the machine it belongs to.

For OEMs, this reduces friction during integration and supports a more consistent development process.

Consistency as a system advantage

Consistency is often associated with user experience, but here it becomes a structural element of development.

When platform and system are aligned, coherence extends across engineering, integration and lifecycle management.

It becomes easier to maintain continuity between machines, evolve existing platforms and manage complexity in a more controlled way.

This applies both to new developments and to machines already in production, where a platform approach can introduce alignment without disrupting existing architectures.

AX400 and AX250: same system, different conditions

Within AX Platforms, AX400 and AX250 respond to different architectural conditions.
AX400 is designed for machines where configurability and functional expansion define the system.

AX250 makes the platform scalable. It brings the same interaction model and system coherence into machines where space becomes a structural constraint: fixed-width cabins and tightly defined layouts.

Not by reducing the system, but by adapting it to constrained environments.

Because when space becomes a constraint, the real challenge is not fitting the interface, it is maintaining control quality within those conditions.

From interface to architecture

AX Platforms reflect a broader shift developed by U-Control.

Not designing an HMI per machine, but defining a system that supports the entire product strategy.

For OEMs, this means gaining control over complexity across development, integration and lifecycle.
