Abstract:
A power steering system of a vehicle and a control method are provided. The system includes a main hydraulic motor that receives engine power and generates a hydraulic pressure and an auxiliary hydraulic motor that generates a hydraulic pressure. A front wheel steering cylinder receives hydraulic pressure and generates power for steering front wheels and auxiliary steering of a driver. A rear wheel steering cylinder receives hydraulic pressure and generates power for steering rear wheels. An integrated control valve connected to the hydraulic motors and the steering cylinders through hydraulic pressure pipelines, and adjusts the hydraulic pressure of a main hydraulic motor to supply the pressure to the front wheel steering cylinder and adjusts the hydraulic pressure generated of the auxiliary hydraulic motor to supply the pressure to the front or rear wheel steering cylinder.
