Electronic hydraulic power steering
The structural principle of electronic hydraulic power assistance is generally the same as that of mechanical hydraulic power assistance, with the biggest difference being the different driving methods used to provide hydraulic oil pumps. The hydraulic pump of mechanical hydraulic assistance is directly driven by the engine belt, while the electronic hydraulic assistance uses an electronic pump driven by electricity.
The electronic hydraulic assisted electronic pump does not consume the power of the engine itself, and the electronic pump is controlled by the electronic system. When steering is not required, the electronic pump is turned off, further reducing energy consumption. The electronic control unit of the electronic hydraulic power Steering System utilizes information processing on sensors such as the vehicle speed sensor and the steering angle sensor, and can change the power of the steering assistance by changing the flow rate of the electronic pump.

Better NVH performance
- Motor design: better PMSM electric motor helps to produce required torque while keeping itself quieter.
- Gear Pump design: customized gear pump design helps to improve the NVH performance.
- Electrical hardware: motor position sensing technology helps to reduce torque ripples.
- Control software: precise control algorithms (including sinusoidal motor control) help to reduce the fluid turbulence in the fluid.
Fully conforms to “Quick response” requirement
- Steering velocity is calculated according to the steering angle received.
- A proprietary algorithm is uesd for quick response to steering maneuvers.
- Steering velocity acceleration rate is also taken into account and utilized to improve the quick response performance.
Less current consumption compared to other equivalent products
- Control algorithm is designed to minimize the chance of generating huge current spikes.
- Motor control phase advance angle is monitored and controlled using current consumption feedback.
- Motor control angle is optimized to reduce current consumption at idle speed.
