The present invention relates to a steering control apparatus and a steering control method. Only measurement information such as a vehicle speed (), a steering angle (), and a yaw rate () of a vehicle and vehicle characteristic information of a wheelbase (L) between a front wheel and a rear wheel of the vehicle and a steering angle/front wheel rotation ratio (i) are used to easily determine five steering states of the vehicle including a neutral steering state, a simple understeer state, an understeer state with a slip, a simple oversteer state, and an unstable oversteer state and calculate a compensation current or compensation torque for abnormal steering state compensation to control the compensation current or the compensation torque to secure vehicle stability in an abnormal steering state.

    본 발명은 조향 제어 장치 및 방법에 관한 것으로서, 차량의 차속(ν), 조향각(δ) 및 요레이트(Yaw Rate;) 등의 측정정보와, 차량 전륜-후륜 사이의 휠베이스(L) 및 조향각/전륜 회전비율(i)의 차량 특성정보만을 이용하여 차량의 조향 상태, 즉 중립조향상태, 단순 언더스티어 상태, 술립있는 언더스티어 상태, 단순 오버스티어 상태, 불안정 오버스티어 상태의 5가지 조향 상태를 용이하게 판단하고, 비정상 스티어링 상태 보상을 위한 보상토크 또는 보상전류를 산출하여 제어함으로써, 비정상 조향 상태에서의 차량 안정성을 확보할 수 있다.
