본 발명은 도로 환경에 따른 충돌 위험 추정 방법에 관한 것이다. 도로 환경에 따른 충돌 위험 추정 방법은, 적어도 하나의 센서를 이용하여 노면 마찰계수 분포를 추정하는 단계, 추정된 노면 마찰계수 분포 및 자차량의 예상 감속량을 이용하여 도로 환경에 따른 자차량의 예상 감속량 분포를 산출하는 단계, 산출된 자차량의 예상 감속량 분포를 이용하여 자차량과 전방 차량과의 전방 안전거리 분포를 산출하는 단계 및 산출된 전방 안전거리 분포를 기초로 자차량과 전방 차량과의 현재 거리에 따른 전방 충돌 위험도를 산출하는 단계를 포함한다.
A method for estimating a collision risk according to a road environment is provided. The method for estimating a collision risk according to a road environment may include estimating a road surface friction coefficient distribution using at least one sensor, calculating an expected deceleration amount distribution of an own vehicle according to the road environment using the estimated road surface friction coefficient distribution and an expected deceleration amount of the own vehicle, calculating a forward safety distance distribution between the own vehicle and a forward vehicle using the calculated expected deceleration amount distribution of the own vehicle, and calculating a forward collision risk according to a current distance between the own vehicle and the forward vehicle based on the calculated forward safety distance distribution.
