Claim 5:
6. A decompression method for decompressing compressed gas generated by a gas generating device configured to generate the compressed gas, the decompression method comprising:
determining a regulating amount of a flow regulating valve provided on a discharge flow path through which the compressed gas flowing out from the gas generating device flows, the regulating amount being determined based on a pressure detected by a pressure sensor provided on the discharge flow path;
correcting the determined regulating amount based on a temperature detected by a temperature sensor provided on the discharge flow path;
measuring a change rate of the pressure that is a change in the pressure per unit time, from a start of control of the flow regulating valve; and determining the regulating amount according to the measured change rate;
varying the regulating amount so as to reduce a difference between the change rate and a target change rate;
estimating a temperature gradient of the compressed gas based on the temperature detected by the temperature sensor at the start of the control of the flow regulating valve and an outside air temperature detected by an outside air temperature sensor at the start of the control of the flow regulating valve;
further correcting the determined regulating amount based on the estimated temperature gradient; and
controlling the flow regulating valve according to the corrected regulating amount.
