Abstract

This study examined a fire accident caused by a defect in the vehicle ABS module. A large number of vehicles using the same manufacturer's ABS module in recent fire events showed a tendency to combust due to the same faults. As previously stated in the ABS module which shows the electrical breakdown between the power lines supplied to the constant power source by the battery. The electrical breakdown of the ABS module was caused by defects of the ABS module itself that were influenced by of the external flame. These results highlight the need to determine if there is a deficiency of the ABS module in the investigation of the cause of a fire in a vehicle which is produced by the same manufacturer.

본 논문에서는 자동차 ABS 모듈의 결함으로 인한 화재사고에 대하여 기술하였다. 최근 발생한 화재 사례 중 동일 제조사의 ABS 모듈을 적용하는 다수의 차량에서 유사한 결함으로 인해 화재가 발생하는 경향을 나타내었다. 앞서 언급한 ABS 모듈에서는 배터리를 통해 상시전원으로 공급되는 전원배선 사이에서 절연파괴가 발생되는 특징을 나타내는데 이러한 부분은 연소 확대 과정에서 외부 화염에 의해 형성되기 어려운 부분으로 ABS 모듈 자체의 결함으로 판단된다. 본 연구의 결과로 부터 특정 제조사에서 생산 판매되는 차량에 대한 화재원인 조사에 있어서는 반드시 ABS 모듈의 결함 여부에 대한 조사가 필수적으로 진행되어야 할 것이다.
