The present invention relates to a method for controlling a black box apparatus and a black box apparatus integrally managed for diagnosing a defect of a vehicle by recording all data related to abnormal operations in the black box apparatus to be backed up when the abnormal operations occur in a plurality of electronic control units (ECU) inside the vehicle. According to the present invention, the black box apparatus comprises: a CAN module receiving a message related to occurrence of the abnormal operations from the ECUs inside the vehicle through CAN communications; a wireless communications module for communicating with an external server; and a microcontroller unit (MCU) determining whether or not the message received from the CAN module indicates the critical defect, dumping the received message to be transmitted to the external server through the wireless communications module when the CAN module indicates the critical defect, and storing the received message in a database to be backed up when the CAN module indicates the simple defect.

    본 발명은 차량 내 다수의 전자제어유닛으로부터 이상 동작이 발생하면 이상 동작과 관련한 데이터들을 블랙박스장치에 모두 기록하여 백업함으로써 차량의 이상 진단을 위해 통합 관리가 가능한 블랙박스장치 및 이의 제어 방법에 관한 것으로, 본 발명의 블랙박스장치는 캔(CAN) 통신을 통해 차량 내 다수의 전자제어유닛(ECU)로부터 이상 동작 발생과 관련한 메시지를 수신하는 CAN 모듈과, 외부의 서버와 통신하기 위한 무선통신모듈, 및 CAN 모듈로부터 수신한 메시지가 치명적인 고장인지를 판단하고 치명적인 고장이면 무선통신모듈을 통해 외부의 서버로 수신한 메시지를 덤핑하여 전송하며, 단순 결함이면 수신한 메시지를 데이터베이스에 저장하여 백업하는 제어모듈(MCU)을 포함한다.
