  • Patent number: 10107705
    Abstract: When a calibration starting condition of a pressure sensor is satisfied while a fuel cell vehicle is traveling, the fuel cell vehicle starts to travel by using electric power supplied from a secondary battery. In the fuel cell vehicle, a pressure sensor is calibrated based on hydrogen pressure in a hydrogen gas flow channel downstream of a pressure reducing valve after a shut-off valve of a hydrogen tank is closed, and the hydrogen in a hydrogen gas flow channel is exhausted until hydrogen pressure upstream of the pressure reducing valve and hydrogen pressure downstream of the pressure reducing valve become substantially equal to each other. The fuel cell vehicle travels by using electric power supplied from the secondary battery while the pressure sensor is being calibrated, so that calibration processing of the pressure sensor can be performed without causing a noise.

  • Publication number: 20180233756
    Abstract: A shutoff valve, a first gas pressure sensor, a pressure reducing valve, a second gas pressure sensor, and a gas supply component are provided, sequentially from a gas tank side, in a gas supply flow channel that extends from the gas tank to a gas consuming component. Besides, a buffer tank is provided, via an on-off valve, in a branch flow channel that branches off from the gas supply flow channel between the pressure reducing valve and the gas supply component. This buffer tank is in a situation where the pressure of the buffer tank is not higher than a consumption prescribed gas pressure. In calibrating the first gas pressure sensor, with the shutoff valve closed and with the on-off valve open, a detection value of the first gas pressure sensor is calibrated through the use of a detection value of the second gas pressure sensor.
