| description | The present invention relates to a power control device diagnosing disconnection failure generated in a power system of an autonomous driving vehicle, and a disconnection failure diagnosis method thereof. The power control device comprises: a power control switch connecting or separating main power outputted from a first power supply device and auxiliary power outputted from a second power supply device; and a processor determining possibility of short-circuit failure of vehicle power based on a current flowing to the power control switch and determining a short-circuit position based on output of the first power supply device and whether electric load is driven only by output power of the second power supply device when there is the possibility of the short-circuit failure.
본 발명은 자율주행차량의 전원 계통에 발생하는 단선 고장을 진단하는 전력 제어 장치 및 그의 단선 진단 방법에 관한 것으로, 제1 전원 공급 장치로부터 출력되는 주 전원과 제2 전원 공급 장치로부터 출력되는 보조 전원을 연결하거나 분리하는 전원 제어 스위치, 및 상기 전원 제어 스위치에 흐르는 전류에 기반하여 차량 전원의 단선 고장 가능성을 판단하고, 상기 단선 고장 가능성이 있는 경우, 상기 제2 전원 공급 장치의 출력 전력만으로 전장 부하 구동 여부 및 상기 제1 전원 공급 장치의 출력을 기반으로 단선 위치를 판단하는 프로세서는 포함한다. |
