The present invention relates to a method for recognizing road condition, comprising: a step of monitoring an acceleration sensor signal of a vehicle; a step of, when an instantaneous change volume of an acceleration sensor signal is equal to or higher than a certain reference change volume, determining if the acceleration change of the vehicle is due to an internal situation of the vehicle; a step of, when the acceleration change of the vehicle is not due to an internal situation of the vehicle, determining that the acceleration change is due to a road condition, and transmitting the information including the position on the road which has caused the acceleration change to an integrated management system by the vehicle; a step in which the integrated management system receives the information transmitted by the vehicle, and calculates the reliability of the received information; and a step in which, when the reliability is equal to or higher than a certain reference value, the integrated management system determines that the relevant position on the road is in a state to cause the acceleration change of a vehicle. The present invention is able to secure more improved performance for driving a vehicle.

    본 발명은 차량의 가속도센서 신호를 모니터링하는 단계; 상기 가속도센서 신호의 순간 변화량이 소정의 기준변화량 이상인 경우, 차량의 가속도 변동이 차량 내부 상황에 따른 것인지를 판단하는 단계; 상기 가속도 변동이 차량 내부 상황에 따른 것이 아닌 경우, 도로 상태에 따른 가속도 변동으로 판정하고, 상기 가속도 변동을 초래한 도로상의 위치를 포함하는 정보를 상기 차량이 통합관리시스템으로 송신하는 단계; 상기 통합관리시스템이 상기 차량이 송신한 정보를 수신하여, 수신된 정보의 신뢰성을 산출하는 단계; 상기 신뢰성이 소정의 기준값 이상인 경우, 상기 통합관리시스템이 상기 도로 상의 해당 위치가 차량의 가속도 변동을 초래할 상태인 것으로 확정하는 단계를 포함하여 구성된다.
