To provide a method for controlling a fuel cell vehicle and a fuel cell vehicle which, while preventing the occurrence of buckling of a high-pressure tank for storing fuel gas, suppress a rapid power decrease in the fuel cell vehicle.SOLUTION: When a gas pressure P in a high-pressure tank 80 becomes lower than a first threshold pressure P1, the SOC of a power storage device 14 is increased to a margin SOCm. Then, when the gas pressure P becomes a second threshold pressure P2 lower than the first threshold pressure P1, the amount of fuel released from the high-pressure tank 80 is limited to prevent the occurrence of buckling, and travel driving force by a motor 24 is limited to a minimum necessary level. At the time of limitation, assistance is provided so that the travel driving force by the motor 24 becomes the travel driving force at the minimum necessary level with the electric power of the power storage device 14.SELECTED DRAWING: Figure 4
【課題】燃料ガスを貯蔵する高圧タンクのバックリングの発生を防止しつつ、燃料電池車両の急激な動力低下を抑制する燃料電池車両の制御方法及び燃料電池車両を提供する。【解決手段】高圧タンク80内のガス圧Pが第1閾圧P1未満となったときに、蓄電装置14のSOCを余裕SOCmまで増加させ、前記ガス圧Pが前記第1閾圧P1より小さい第2閾圧P2となったときに、前記高圧タンク80から放出される燃料量を制限してバックリングの発生を防止し、且つ前記モータ24による走行駆動力を必要限度に制限する。制限する際、前記蓄電装置14の電力により前記モータ24による走行駆動力が前記必要限度の走行駆動力となるようアシストする。【選択図】図4
