Frequently Asked Questions
Electro-hydraulic power steering (EHPS) is an electrically driven hydraulic steering system that uses an electric motor to power the hydraulic pump instead of relying on the vehicle engine. This enables more efficient operation and intelligent control of steering assistance.
Our EHPS systems are designed for commercial vehicle applications, including heavy-duty trucks, medium- and light-duty trucks, electric buses, passenger vehicles, and specialty vehicles.
Our EHPS portfolio covers rated power from 1.5 kW to 10 kW and peak power from 3 kW to 22 kW, supporting different vehicle sizes and steering requirements.
Compared with conventional hydraulic power steering systems, EHPS uses an ECU-controlled electric motor to operate the hydraulic pump only when required, reducing unnecessary energy consumption while providing adjustable steering assistance based on vehicle speed and driving conditions.
The ECU continuously adjusts motor speed and hydraulic flow according to vehicle speed and steering input, enabling optimized steering assistance, improved stability, and enhanced driving comfort.
Our EHPS products have been supplied for commercial vehicle applications including electric buses, trucks platforms from multiple OEM customers.
Our EHPS products are validated through performance testing, durability testing, environmental testing, noise evaluation, and other verification processes. Manufacturing is supported by intelligent production systems and IATF 16949 quality management standards.
Typical production lead time is approximately 60 days, depending on product configuration, order quantity, and production scheduling. Please contact our sales team for project-specific delivery schedules.
