Abstract
Decrease speed (gas pressure decrease speed) of fuel gas pressure in an in-vehicle fuel gas container and elapsed time after the fuel gas pressure reaches a predetermined lower limit value are measured. Then, based on the gas pressure decrease speed and the elapsed time, it is determined whether or not a burping occurrence condition where a fuel gas which entered space between an inner layer and an outer layer of the in-vehicle fuel gas container is discharged to the outside of the outer layer is satisfied. If the burping occurrence condition is satisfied, at the time of filling the fuel gas in the in-vehicle fuel gas container, control to prevent detection of the fuel gas by the fuel gas detector is performed.
