Rear-axle steering for heavy off-road vehicles towards 2028

Off-road vehicles require maximum manoeuvrability in confined spaces for use in open-pit mines, heavy-duty construction and other specialist applications. The next step after ETS is EMS: an electro-hydraulic steering system with more direct motor control and a more compact system architecture, developed to ASIL-D level and tailored to heavy-duty off-road platforms. Its launch is scheduled for 2028.

Why choose EMS for off-road vehicles?

Smaller turning circle on switchbacks and confined haul roads
EMS reduces the turning circle and improves manoeuvrability, minimising the number of manoeuvres required and reducing tyre wear on tight off-road sections.

More direct actuation, compact architecture
By integrating the valve block into the pump, EMS provides greater control, reduced energy loss, and a more compact system design.

Compact for electric and hybrid off-road platforms
Thanks to its compact system architecture, EMS is well-suited to electric and hybrid off-road vehicle platforms where space is at a premium.

Developed to ASIL-D level
EMS is being developed in accordance with ASIL-D to ensure predictable and safe control behaviour in challenging operational conditions.

Scalability and advanced vehicle functionality

Smart actuator functionality
EMS converts direct control signals into axle movements, offering OEMs greater flexibility in terms of vehicle software and architecture.

Support for multiple steered axles
EMS supports multiple driven axles via parallel systems, making it ideal for complex 6×6 and 8×8 vehicle configurations.

Crab steering on the roadmap
Crab steering is included in the EMS roadmap, allowing it to be incorporated into the development process from an early stage.

Join early as a development partner

EMS is being developed together with a limited number of vehicle manufacturers. This is a co-development programme, not a standard customer-supplier trajectory. As an early partner, you can:

  • Contribute technical requirements, axle configurations and integration questions at an early stage
  • Be the first to develop and offer off-road vehicles with EMS from launch onwards
  • Work directly with engineers on integration and validation for your specific terrain and axle-load profile
  • Influence future roadmap features, such as crab steering and multi-axle configurations for heavy vehicles
