According to the present invention, disclosed is a processing method of an acoustic-based vehicle abnormality detection system comprising the steps of: (a) collecting vehicle information including an acoustic signal generated from mechanical or electronic devices of a vehicle and a vehicle number and a vehicle type of the vehicle; (b) digitizing the collected acoustic signal to generate acoustic information data; (c) mapping the acoustic information data onto an error database (DB) for each vehicle type, which is previously converted into a database, or analyzing a pattern of acoustic information to detect an abnormality of the vehicle; and (d) generating an abnormality report when the abnormality is found in the acoustic information, storing the abnormality report in the error DB for each vehicle type, and notifying a service provider or a driver of an abnormal situation.

    본 발명은 (a) 차량의 기계 또는 전자 장치들에서 발생하는 음향 신호와 해당 차량의 차량번호 및 차종을 포함하는 차량 정보를 수집하는 단계; (b) 수집된 음향 신호를 디지털화하여 음향 정보 데이터를 생성하는 단계; (c) 상기 음향 정보 데이터를 미리 데이터베이스화되어 있는 차종별 오류DB와 매핑하거나, 음향 정보의 패턴을 분석하여 차량의 이상 징후를 검출하는 단계; 및 (d) 음향 정보에서 이상 징후가 발견된 경우 이상 징후 레포트를 생성하여 상기 차종별 오류DB에 저장하고 서비스 제공사 또는 운전자에게 비정상 상황 발생을 알리는 단계;를 포함하는 음향기반 자동차 비정상 징후 감지시스템의 처리방법을 개시한다.
