Disclosed are an apparatus and a method for estimating a curvature. According to an embodiment of the present invention, the apparatus for estimating a driving curvature of a vehicle comprises: a first calculator calculating a change amount of the driving curvature of the vehicle in accordance with a change in a steering angle compared to a reference steering angle; a first combiner calculating a first estimated curvature value in accordance with the change in the steering angle by reflecting the change mount of the driving curvature; a second calculator calculating a second estimated curvature value by using a yaw rate and a vehicle speed; and a second combiner calculating a final estimated curvature value by using at least one of the first estimated curvature value and the second estimated curvature value.

    본 발명은 곡률 추정 장치 및 방법에 대하여 개시한다. 본 발명의 일면에 따른 차량의 주행 곡률을 추정하는 장치는, 기준 조향각에 대비한 조향각 변화에 따른 상기 차량의 주행곡률의 변화량을 산출하는 제1 계산기; 상기 주행곡률의 변화량을 반영하여 상기 조향각의 변화에 따른 제1 곡률 추정치를 산출하는 제1 결합기; 요-레이트(Yaw-Rate)와 차량속도를 이용하여 제2 곡률 추정치를 산출하는 제2 계산기; 및 상기 제1 곡률 추정치와 상기 제2 곡률 추정치 중 적어도 하나를 이용하여 최종 곡률 추정치를 산출하는 제2 결합기를 포함하는 것을 특징으로 한다.
