Disclosed are a method and apparatus for measuring road surface conditions by using an optical sensor installed in a vehicle and the slip ratio of tires of the vehicle and detecting black ice on a road surface. The disclosed method for measuring road surface conditions comprises the steps of: determining whether the road surface on which the vehicle moves is frozen; and when the road surface is frozen, detecting black ice on the road surface by using an infrared sensor installed in the vehicle.

    La présente invention concerne un procédé et un appareil permettant de mesurer des conditions de surface de route au moyen d'un capteur optique installé dans un véhicule et du rapport de glissement des pneus du véhicule et de détecter de la glace noire sur une surface de route. Le procédé de mesure de conditions de surface de route comprend les étapes consistant : à déterminer si oui ou non la surface de route sur laquelle le véhicule se déplace est gelée ; et lorsque la surface de route est gelée, à détecter de la glace noire sur la surface de route au moyen d'un capteur infrarouge installé dans le véhicule.

    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.
