Abstract
An electro-hydraulic power steering apparatus for an environment-friendly vehicle and a method of controlling the same is provided. In particular, a gear box assists in a steering force of a steering wheel, and a reservoir tank stores hydraulic oil therein. An electro-hydraulic power pump pumps the hydraulic oil via an electric motor to supply the hydraulic oil to the gear box. A first valve is mounted to a hydraulic line through which the hydraulic oil flows from the electro-hydraulic power pump to the gear box, and a second valve is mounted to a hydraulic line through which the hydraulic oil returns from the gear box to the reservoir tank.
