Disclosed are an apparatus for estimating the position of a vehicle using a gradient of a road, and a method therefor which precisely estimates the position of a vehicle by applying a tilt angle of a road. The disclosed method for estimating the position of a vehicle using a gradient of a road comprises: a step of receiving plane speed information and vertical speed information of the vehicle from a GPS device; a step of generating tilt angle information of the road using the plane speed information and the vertical speed information; and a step of correcting the position of the vehicle using the tilt angle information. 도로의 경사각을 반영하여 차량의 위치를 정밀하게 추정할 수 있는 차량 위치 추정 방법 및 장치가 개시된다. 개시된 차량 위치 추정 방법은, GPS 장치로부터 차량의 평면 속도 정보 및 수직 속도 정보를 입력받는 단계; 상기 평면 속도 정보 및 수직 속도 정보를 이용하여, 도로의 경사각 정보를 생성하는 단계; 및 상기 경사각 정보를 이용하여, 상기 차량의 위치를 보정하는 단계를 포함한다.
