Abstract: PURPOSE: A power steering system of an electric vehicle is provided to enhance engine power and fuel efficiency by adjusting steering effort according to traveling velocity and by using a hydraulic pump for an engine mounted vehicle. CONSTITUTION: To adjust a direction, a driver rotates a steering wheel and hydraulic pressure from a hydraulic pump(30) is transmitted to a gear box(40) for setting the direction. At that time, the hydraulic pump is driven by an electromotor(20). The electromotor is driven by an electromotor controller(60) receiving a signal from a velocity sensor(50). The electromotor rpm(revolutions per minute) interlocks with the velocity of a vehicle so that steering effort is adjusted depending on the velocity. A decelerator(25) mounted on an output shaft(21) of the electromotor transmits torque to the hydraulic pump. The hydraulic pump is also driven due to the engine of a general vehicle instead of the electromotor.
