The present invention provides a method to estimate a road curvature on which a vehicle runs by using a GPS or a navigation device except for an existing camera in a situation where a traffic lane can hardly be recognized. According to an embodiment of the present invention, the method to estimate the road curvature comprises: a step of providing a GPS coordinate located in front of a vehicle in a route set by the navigation device; a step of generating database (DB) by storing the provided GPS coordinates in order of being close; a step of correcting a rear GPS coordinate located on a rear of the vehicle using information obtained through driving of the vehicle, wherein the rear GPS coordinate points where the vehicle passes, among the GPS coordinate stored in the DB; and a step of correcting a front GPS coordinate located in front of the vehicle based on content in which the rear GPS coordinate is corrected, wherein the front GPS coordinate is stored in the DB.

    본 발명의 일 실시 예에 따른 도로 곡률 추정 방법은 네비게이션을 통해서 설정된 경로에서 차량의 전방에 위치한 GPS 좌표가 제공되는 단계, 상기 제공된 GPS 좌표들을 상기 차량으로부터 가까운 순서대로 저장하여 DB(data base)를 생성하는 단계, 상기 DB에 저장된 상기 GPS 좌표 중 상기 차량이 지나온 지점들인 상기 차량의 후방에 위치한 후방 GPS 좌표를 상기 차량의 운행으로 획득되는 정보를 이용하여 보정하는 단계, 및 상기 후방 GPS 좌표를 보정한 내용을 기반으로, 상기 DB에 저장된 상기 차량의 전방에 위치한 전방 GPS 좌표를 보정하는 단계를 포함하는 것을 특징으로 한다.
