전자 브레이크를 적용한 연료전지자동차 회생제동 시스템의 신뢰성 평가기술 개발 PART-(2)

The demand of the green car like hybrid electric vehicle, fuel cell electric vehicle(FCEV) and pure electric vehicle have risen dramatically. The key technology is the regenerative braking in the energy saving technology. And electronic brake has been developed along with the advance of the electronic control technology. The reliability about the braking system is very important because the braking system is concerned with safety of vehicle. But the regulation is not sufficient enough. In this study, to develop the reliability assessment technology FCEV model with regenerative braking system and electronic braking system(EWB, EMB) was developed. The reliability assessment scenarios about regenerative braking system and electronic braking system is developed using ABS brake regulations and FMEA results. This scenarios ware applied to the performance simulation of the FCEV with the regenerative braking and the electronic braking system. And the fail-safe control strategy of a EMB was suggested and verified.
