Disclosed are a method and an apparatus for measuring a road surface condition using an optical sensor installed in a vehicle and a slip rate of a vehicle tire, and detecting black ice on a road surface. The disclosed method for measuring a road surface condition includes the steps of: determining whether the road surface on which the vehicle is running is frozen; and detecting black ice on the road surface using an infrared sensor installed in the vehicle when the road surface is frozen.
차량에 설치된 광학 센서와 차량 타이어의 슬립률을 이용하여 노면 상태를 측정하고, 노면의 블랙 아이스를 감지하는 방법 및 장치가 개시된다. 개시된 노면 상태 측정 방법은 차량이 주행하는 노면의 결빙 여부를 판단하는 단계; 및 상기 노면이 결빙된 경우, 상기 차량에 설치된 적외선 센서를 이용하여, 상기 노면의 블랙 아이스를 감지하는 단계를 포함한다.
