Provided are an electric power steering apparatus for a vehicle and a control method thereof, wherein motors capable of assisting motor-operated steering are installed around a steering column and a steering rack rear, respectively, so it is possible to improve steering responsiveness and driving safety by controlling each of the motors according to a parking mode and a driving mode. To this end, the electric power steering apparatus for a vehicle comprises: a first steering motor which is disposed around the steering column; a second steering motor which is disposed around the steering rack gear; a vehicle velocity sensor; and a controller which determines whether the parking mode or the driving mode is turned on by using a vehicle velocity detected by the vehicle velocity sensor to control the first steering motor and the second steering motor to assist the steering at the same time when the parking mode is turned on and control the second steering motor to assist the steering when the driving mode is turned on.

    조향 컬럼 측과 조향 랙 기어 측에 각각 전동식으로 조향을 보조할 수 있는 모터가 설치되어, 주차모드 및 주행모드에 따라 각각의 상기 모터를 제어하여 조향 응답성 및 주행 안전성을 향상시킬 수 있는 차량용 전동식 파워 스티어링 장치 및 그것의 제어방법이 제공된다. 이를 위해, 본 발명에 따른 차량용 전동식 파워 스티어링 장치는, 조향 컬럼 측에 배치되는 제1 조향 모터와, 조향 랙 기어 측에 배치되는 제2 조향 모터와, 차속 센서와, 상기 차속 센서가 감지한 차속을 이용하여 주차모드인지 주행모드인지를 판단하여 상기 주차모드이면 상기 제1 조향 모터 및 상기 제2 조향 모터가 동시에 조향을 보조하도록 제어하고 상기 주행모드이면 상기 제2 조향 모터가 조향을 보조하도록 제어하는 컨트롤러를 포함한다.
