Disclosed is a method for a rear cross-traffic collision warning, comprising the following steps of: dividing an area around an own vehicle into a plurality of cells arranged in the vertical and horizontal directions, and creating a grid map in which cells corresponding to positions at which a stationary object is detected around the own vehicle by a radar are divided into occupied cells; determining a location of a reflective structure reflecting a radar signal based on a positional relationship between the occupied cells in the grid map; and determining whether a tracking target is false based on the determined location of the reflective structure and the location or movement direction of the tracking target detected by the radar. An objective of the present invention is to provide the method and a system for a rear-traffic cross collision warning, capable of determining whether the recognized tracking target is a false tracking target.

    자차의 주변 영역을 종횡방향으로 배치된 복수의 셀로 구분하고, 레이더에서 상기 자차 주변의 정지 물체를 감지한 위치에 대응되는 셀을 점유 셀로 구분한 그리드 맵을 작성하는 단계; 상기 그리드 맵에서 상기 점유 셀 사이의 위치 관계에 기반하여 레이더 신호를 반사하는 반사 구조물의 위치를 판정하는 단계; 및 판정된 상기 반사 구조물의 위치와 상기 레이더에서 감지된 추적 대상의 위치 또는 이동 방향에 기반하여 상기 추적 대상의 허위 여부를 판단하는 단계를 포함하는 후방 교차 충돌 경고 방법이 개시된다.
