The present invention provides a device and a method for controlling the steering power of a motor-driven power steering system. The method for controlling the steering power of a motor-driven power steering system comprises: a calculation step of calculating a correction value caused by a difference between a left turn output value and a right turn output value by detecting the left turn output value and the right turn output value, respectively during the right and left turn of a column around a center steering angle; and a map-correcting step of correcting a map so that left turn assist and right turn assist can be controlled independently using different steering power by correcting at least one among a left turn assist output value and a right turn assist output value, which are formed on the map for representing the relation of the assist output values to left turn and right turn, using the correction value.

    본 발명은, 센터조향각을 중심으로 컬럼의 좌우 회전시, 좌선회출력값 및 우선회출력값을 각각 계측하여, 좌선회출력값 및 우선회출력값의 차이에 따른 보정값을 연산하는 연산단계; 상기 보정값에 의해, 좌선회 및 우선회에 대한 어시스트출력값과의 관계를 나타낸 맵에 형성된 좌선회 어시스트출력값 또는 우선회 어시스트출력값 중 적어도 어느 하나 이상을 보정함으로써, 좌선회 어시스트제어 및 우선회 어시스트제어를 상이한 조향력으로 독립 제어 가능하도록 맵을 보정하는 맵보정단계;를 포함하여 구성되는 전동식 파워스티어링 시스템의 조향력 제어방법 및 장치가 소개된다.
