NF Group Electric Hydraulic Steering Pump for Electric Vehicle
Description
Definition & Working Principle
- Working Process:
- The electric motor drives the hydraulic pump to generate pressure.
- Hydraulic fluid is delivered to the steering gear, which amplifies the driver’s steering force, making steering lighter.
- A control unit adjusts the motor’s speed (and thus the pump’s output) based on factors like steering wheel speed, vehicle speed, and driver input, ensuring optimal assistance.
Key Components
- Electric Motor: Typically a brushless DC motor for high efficiency and durability.
- Hydraulic Pump: Generates pressure; designs include vane pumps, gear pumps, or axial piston pumps.
- Control Module: Processes sensor data (steering angle, vehicle speed, torque) to regulate motor speed and pump output.
- Reservoir & Hydraulic Fluid: Stores and circulates fluid to transmit power.
Main advantages
Energy-saving and high efficiency: the greatest advantage. It avoids the constant power loss of the engine-driven pump, especially when driving at high speed in a straight line, it almost does not consume energy, and can reduce fuel consumption by about 0.2-0.4L/100km.
Enhance power performance: Without occupying the space and power of the front-end wheel system of the engine, the engine power is used more purely for vehicle propulsion.
Adjustable assist characteristics: Through software programming, it is easy to achieve variable assist characteristics of "light at low speed and stable at high speed", and even integrate different driving modes (comfort, sport).
Flexible layout: No need to align with the engine crankshaft pulley, allowing for more freedom in placement within the engine compartment.
Compatibility and Transition: Highly suitable for hybrid vehicles. It can still provide stable steering assistance during engine auto-stop and start or pure electric driving.
Laying the groundwork for autonomous driving: Its electronic control characteristics are more conducive to integration with advanced driver assistance systems, enabling automatic steering control.

Application
Applications
- Passenger Vehicles: Widely used in modern cars, especially hybrids and EVs (e.g., Toyota Prius, Tesla models) where engine-driven systems are impractical.
- Commercial Vehicles: Light trucks and vans benefit from EHPS for improved maneuverability and fuel efficiency.
- Specialty Vehicles: Electric buses, construction equipment, and marine vessels use EHPS for reliable, independent steering assistance.
