Electro Hydraulic Power Steering System
NF EHPS-1010R1 5311AB03
EHPS, short for Electro-hydraulic Power Steering, is a technology that falls between traditional hydraulic power steering and pure electric power steering. Traditional HPS: Its hydraulic pump is directly driven by the engine via a belt. As long as the engine is running, the pump operates continuously, consuming energy. This is one reason why the steering wheel is heaviest, and fuel consumption increases when traditional gasoline-powered cars are idling. EHPS: It replaces the engine with a dedicated electric motor. This electric motor is specifically designed to drive the hydraulic pump, thereby generating hydraulic power steering.

Products Advantages: (1) High energy efficiency: Provides energy on demand, significantly reducing energy consumption and improving the range of electric vehicles. (2) Adjustable power assist characteristics: The power assist level can be flexibly set at different vehicle speeds via software, optimizing the driving experience. (3) Good compatibility: Retains a mature hydraulic power assist structure, providing very strong and clear road feel assistance, especially suitable for heavier SUVs and commercial vehicles. (4) Relatively low cost: Compared to pure electric EPS, EHPS may be more cost-effective for vehicles requiring significant power assist. (5) Safety redundancy: Even if part of the electronic system fails, a certain amount of mechanical hydraulic power assist is still retained, ensuring high safety.
