기능 안전 설계/평가 프로세스(ISO 13849) 적용한 지게차용 변속기 제어 유닛(TCU) 개발과 H/W-S/W 레벨 및 실차 레벨 검증

다국어 초록 (Multilingual Abstract)

As the application of automation, intelligent technologies in construction equipment has been increased rapidly, nowadays functional safety regulation on the SRP/CS(Safety Related Parts of Control System) of fork-lift trucks become more strictly applied based on ISO 13849, EN 1175, etc. So, we applied functional safety principles in TCU(Transmission Control Unit) for industrial trucks and performed verification and validation in accordance with ISO 13849, for the first time in Korea. As a result, we developed TCU H/W with the PFHd of 0.392 × 10<SUP>-6</SUP>(1/h). We also conducted S/W tests such as static analysis for MISRA-C compliant rate, dynamic tests for white-box and black-box test, all of which are compliant to PLc/Category 2 or the higher level.
