Abstract
In a vehicle, a first gas sensor detects a hydrogen gas concentration of a vehicle interior front zone. Air-conditioning corresponding to an operation of a suction air switching button or the like is performed until the hydrogen gas concentration of the vehicle interior front zone reaches a predetermined second reference concentration, and any one of interior air mode switching control of an interior/exterior air switching mechanism and stop control of a blower is performed regardless of the operation of the suction air switching button or the like when the hydrogen gas concentration reaches the second predetermined reference concentration.
Claims6
A fuel cell vehicle comprising:
- a fuel cell that is supplied with fuel gas and oxidizing gas and generates electric power;
- a fuel gas tank that stores the fuel gas to be supplied to the fuel cell;
- an air-conditioning control unit that air-conditions a vehicle interior using one of vehicle interior air and vehicle exterior air;
- and
- a gas sensor that detects a fuel gas concentration of fuel gas leaking from a zone in which the fuel cell and the fuel gas tank are mounted,
- wherein the air-conditioning control unit performs priority control of putting priority on the air-conditioning using the vehicle interior air when it is determined that the detected fuel gas concentration is equal to or greater than a predetermined threshold concentration.
A control method of a fuel cell vehicle, comprising:
- detecting a fuel gas concentration of fuel gas leaking from a zone in which a fuel cell and a fuel gas tank are mounted in the fuel cell vehicle;
- and
- performing priority control of putting higher priority on air-conditioning using vehicle interior air than air-conditioning using vehicle exterior air when it is determined that the detected fuel gas concentration is equal to or greater than a predetermined threshold concentration.
