CONTROL METHOD FOR HYDROGEN LEAK DETECTING SYSTEM OF FUEL CELL VEHICLE

摘要

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.
