Zusammenfassung:	The present invention relates to a redundancy control system of an autonomous vehicle. According to an embodiment disclosed in the present invention, passenger safety can be ensured even if a failure occurs in one or both of a first CPU, which is a main processor, and a second CPU, which is a backup processor, included in a controller. Additionally, even if the failure occurs in both the first CPU and the second CPU, which is the backup processor, an MCU independently generates a decision signal to control the autonomous vehicle. Accordingly, measures in response to a failure condition can be appropriately performed without driver intervention. The redundancy control system of the autonomous vehicle of the present invention comprises: the first CPU and the second CPU; and the MCU. 본 발명은, 자율주행차량의 리던던시 제어 시스템에 관한 것으로서, 본 발명에 개시된 실시예에 따르면, 제어기에 포함된 메인 프로세서인 제1 CPU와 백업 프로세서인 제2 CPU 중 어느 하나 또는 모두에 고장이 발생한 경우에도 탑승객의 안전을 확보할 수 있고, 제1 CPU와 백업 프로세서인 제2 CPU 모두에 고장이 발생한 경우에도 MCU가 독립적으로 판단 신호를 생성하여 자율주행차량을 제어하므로 운전자의 개입없이 상기 고장 상태에 대응하는 조치를 적절히 수행할 수 있다.
