The present invention relates to a steering apparatus for a vehicle, and is intended to solve a problem that an initial steering feel is not maintained due to wear of an internal member of the steering apparatus. According to the present invention, a reference rack thrust value at a steering angle is set and the rack thrust value under a same learning condition as the setting is collected. In addition, the collected rack thrust value is compared with the reference rack thrust value, a frictional compensation gain for compensating a difference between the collected rack thrust value and the reference rack thrust value is calculated, and the calculated frictional compensation gain is applied to a calculation of a driving current of a motor, thereby continuously providing a user with the initial steering feel.

    본 발명은 차량의 조향 장치에 관한 것으로서 조향 장치의 내부 부재의 마모 등으로 인하여 초기의 조향감이 유지되지 않는 문제를 해결하기 위한 것이다. 본 발명에 따르면, 조향각에서의 기준 랙추력 값을 설정하고 설정시와 동일한 학습조건에서 랙추력 값을 수집하며, 수집된 랙추력 값을 기준 랙추력 값과 비교하여 그 차이를 보상할 수 있는 프릭션 보상 게인을 산출하고 산출된 프릭션 보상 게인을 모터의 구동전류 산출에 적용함으로써, 사용자에게 초기의 조향감을 지속적으로 제공할 수 있도록 한다.
