Abstract

본 발명은 노면센서를 이용하여 노면의 상태를 감지하고 감지된 노면의 상태에 따라 충돌방지 경보시점을 최적제어할 수 있도록 한 자동차의 충돌방지 경보장치에 관한 것이다.The present invention relates to an anti-collision warning device for a vehicle that detects a road surface using a road surface sensor and optimally controls an anti-collision alarm time point according to the detected road surface state.

본 발명은 자차의 현재속도에 따른 정지거리를 산출하고 상기 산출된 정지거리와 자차와 전방차량과의 차간거리를 비교하여 충돌가능성이 있다고 판단될 때 경보를 발하는 자동차의 충돌방지 경보장치에 있어서, 노면의 상태를 감지하는 수단(12) 및 상기 노면상태 감지수단으로부터 제공된 정보에 의거하여 현재의 노면상태를 판단하고 상기 판단된 노면상태를 하나의 변수로 하여 정지거리를 산출한 후에 충돌방지 경보시점을 결정하는 마이크로프로세서(1)를 구비한 것을 특징으로 한다. 상기 노면상태감지수단(12)은 노면에 대하여 레이져빔을 발사하고 되돌아오는 레이져빔의 편광비와 난반사의 크기를 감지한다.The present invention provides an anti-collision warning device for a vehicle which calculates a stopping distance according to the current speed of the own vehicle and issues an alarm when it is determined that there is a possibility of collision by comparing the calculated stopping distance with the distance between the own vehicle and the front vehicle. The collision prevention alarm point is determined after determining the present road surface state based on the information provided from the road surface state detecting means 12 and the information provided from the road surface state detecting means, and calculating the stopping distance using the determined road surface state as one variable. Characterized in that it comprises a microprocessor (1) to determine. The road surface condition detecting means 12 detects the polarization ratio and the size of the diffuse reflection of the laser beam which is emitted from the laser beam on the road surface.
