Technology Principle

Electronic hydraulic power English referred to as EHPS, i.e. Electro Hydraulic Power Steering. The system of the steering pump is no longer directly driven by the engine, but rather is driven by an electric motor, and the installation of the electronic control system on the basis of the previous, so that not only the magnitude of the steering assist force and the steeringFor the angle, it is also associated with the vehicle speed. Increasing the hydraulic reaction apparatus and liquid dispensing valve on a mechanical structure, the new electronic control system includes a vehicle speed sensor, solenoid valve, the steering ECU and the like.

Mechanical and hydraulic power works substantially the same, except that the oil pump driven by a motor, while the variable power intensity. After monitoring vehicle speed sensor, the electronic control unit acquires data of the steering control valve opening degree is changed by controlling the oil pressure, steering efforts to achieve size adjustment.
