Mechanical hydraulic power
is a mechanical hydraulic power portion of the engine output power is converted into hydraulic pressure, exert a force to assist steering system to steer the vehicle. Mechanical hydraulic power technology is mature, reliable, low cost, the size of the vehicle are applicable.
Electronic hydraulic power
works with a mechanical hydraulic power substantially the same, except that the motor-driven oil pump, while the variable power efforts. 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.
The electric power
The electric power assist system is provided directly from the electric power unit, the engine power is not directly occupy. While eliminating the power hydraulic assist system necessary steering pump, hoses, hydraulic fluid, and a belt pulley mounted on the engine and other components, the relative energy saving.
