description An electrohydraulic power steering system includes a sensor for detecting steering information, a motor pump unit generating a hydraulic pressure for assisting steering power depending on a driver's steering wheel operation, and a hydraulic cylinder driven with the hydraulic pressure supplied from the motor pump unit to assist the steering power. A control method of the electrohydraulic power steering system includes acquiring steering angle information depending on the driver's steering operation and information on a steering torque applied through a steering wheel at the time of operating the steering wheel; determining a target steering torque depending on the acquired steering angle; and variably controlling a motor rotational speed of the motor pump unit so that the steering torque acquired through the sensor satisfies the target steering torque.
