The present invention provides a system control method to control a hydrogen leak detecting system of a fuel cell vehicle. The control method measures a distance between a smart key and a vehicle, determines whether hydrogen leaks or not using a hydrogen sensor controller when the distance differs from a predetermined distance, informs a driver of hydrogen leakage through cluster indication, flickering of emergency light, or warning sound of a vehicle to warn the driver in accordance with a hydrogen concentration which is leaked, disables starting of an engine of a vehicle or performs engine shutdown for safety of the driver, and initiates a process to cope with leaked hydrogen by operating an air conditioning device which interlinkingly operates with a fuel cell vehicle.
본 발명은 스마트키와 차량의 거리를 측정하여 미리 설정되어 있는 거리를 기준으로 차량과 스마트키의 거리가 변동되는 경우, 수소센서 감지 제어기를 통해 수소 누출 여부를 감지하고, 상기 누출된 수소 농도에 따라 운전자에게 경고하기 위해 클러스터 표출, 비상등 점등 및 차량의 경고음을 통해 수소 누출을 알리거나, 안전조치를 위해 차량의 시동 불능 상태를 유지 또는 시동 셧 다운을 수행하며, 추가로, 연료전지 차량과 연동되는 공조장치의 작동을 통해 누출된 수소에 대응한 프로세스를 가동시키기 위한 시스템 제어방법을 제공하고자 한다.
