As commercial vehicles evolve toward electrification, advanced driver assistance and autonomous driving, steering systems must deliver new levels of efficiency, safety and control. From its proven CPM150 Electro-Hydraulic Power Steering platform to future Electric Power Steering (EPS) and Steer-by-Wire architectures, Sonceboz is developing scalable steering technologies designed to support the next generation of medium- and heavy-duty vehicles.
As the commercial vehicle industry accelerates its transition toward electrification, energy efficiency and advanced driver assistance systems, steering remains a critical function requiring both performance and reliability. Sonceboz continues to lead this transformation with its CPM150 Electro-Hydraulic Power Steering (EHPS), a fully integrated solution specifically designed to meet the demanding requirements of medium- and heavy-duty commercial vehicles.
With numerous vehicle functions transitioning from engine-driven to electrically powered systems, the CPM150 EHPS delivers an efficient and robust steering solution. Its compact integrated electro-hydraulic pump provides up to 200 bar of pressure and 25 l/min of flow, ensuring precise steering assistance across a wide range of operating conditions.
Beyond improving energy efficiency compared with conventional engine-driven hydraulic systems, Sonceboz EHPS technology enables the electrification of steering while maintaining the high-performance levels required by commercial vehicle applications. The system also supports vehicle manufacturers in reducing fuel consumption and emissions while preserving proven steering architectures.
Equipped with redundant 24V electronics and developed according to the highest functional safety standards, the CPM150 platform supports vehicle architectures targeting safety requirements up to ASIL D. These capabilities provide an ideal foundation for advanced driver assistance functions and future autonomous driving applications.
Building upon its expertise in safety-critical steering systems, Sonceboz is also preparing the next generation of steering technologies. These are the Electric Power Steering (EPS) solutions offering further opportunities for integration and control flexibility, as well as Steer-by-Wire architectures designed to unlock new possibilities for autonomous drifving, software-defined vehicles and vehicle design optimization. As part of these future architectures, Sonceboz is developing a Hand Wheel Actuator (HWA) to provide precise steering input detection and configurable force feedback, creating an intuitive connection between the driver and the vehicle.
From EHPS to complete future Steer-by-Wire architectures, including Hand Wheel Actuation, Sonceboz provides OEMs with reliable and scalable steering solutions tailored to the evolving needs of commercial vehicles.
