사용 편의나 안전 서비스를 위해 자동차에 내장되는 전자장치(ECU: Electronic Control Unit)는 증가하고 분산 네트워크 구조에서 운영되도록 네트워크 기반 응용 SW는 더욱 복잡해진다. 복잡해지고 분산화되는 ECU에 적용 가능한 응용 서비스 개발을 위해 운영체제에서부터 플랫폼 및 응용 SW에 이르기 까지 다양한 분야의 산업 표준화가 진행되고 있다. 운영체제 분야에서는 OSEK/VDX,SW 플랫폼 및 응용서 비스 분야에서는 AUTOSAR, 응용서비스의 안전과 신뢰성 검증을 위하여 IEC-61508등에 근거하는 FTA(Fault Tree Analysis) 및 FMEA(Failure Mode and Effect Analysis) 등을 SW 분야에서도 반영하는 추세이다. 본 논문에서는 자동차 전자장치에 사용 되는 IT 기술의 접목 분야별 표준화 동향과 각 국가 및 지역별 추진방향을 살펴본다.
