[ISO26262]Introduction of Functional Safety(기능안전 개요)기록 Memorize/WorkLife 탐구생활 2024. 3. 18. 08:31
차량 내에 전기전자(E/E) 부품의 기능들이 많아지고 복잡해질수록 안전, 보안, 네트워크 요구가 많아지고 있다. 의도하지 않은 전기전자 부품의 고장(Systematic Faults, Random Faults), 예측 가능한 오남용에 대해 기능불충분에 따른 안전 위배( Foreseeable Misuse, Functional insufficiencies), 외부의 공격으로부터 시스템 무력화(Attack/Vulnerabilities) 로부터 보호하기 위해 기능안전(ISO26262) 및 SOTIF, 사이버보안을 만족해야한다. 그 중에 E/E 시스템의 오류로 인한사고방지를 위해 ISO에서 제정한 자동차 기능안전국제규격인 ISO26262에 대해 알아보도록 한다. 기능안전은 법적인 구속력이 없다. the state-..
