The present invention relates to an emergency power supply system for preventing an accident from occurring due to non-supply of power to major control devices related to autonomous driving when power supply fails in an autonomous vehicle. According to an embodiment of the present invention, diagnosis and detection functions are included in the state of a power system and a battery of the autonomous vehicle, a high voltage or a low voltage according to a failure situation of each autonomous driving load is used as a redundant power source to supply power to the main control devices related to autonomous driving, thereby eliminating the risk of the autonomous vehicle caused by power failure to ensure safety.

    본 발명은 자율주행 차량에서 전원공급의 실패 상황시, 자율주행관련 주요 제어기기들에 대한 전원 미공급으로 안전사고가 발생하는 것을 막기 위한 비상 전원공급 시스템에 대한 것으로, 본 발명의 실시예에 따르면, 자율주행차량의 전력계통과 배터리의 상태에 진단과 감지기능을 포함하며, 자율주행 부하별 고장상황에 따른 고전압 또는 저전압 자체를 리던던시 전원으로 활용하여 자율주행관련 주요 제어장치에 대한 전원을 공급하여 전원 미공급에 따른 자율주행차량의 위험성을 제거하여 안정성을 확보할 수 있도록 하는 효과가 있다.
