Abstract
A control method for a fuel cell vehicle includes a failure determining step of determining whether or not a failure exists in a fuel cell system. A safe driving step stops an operation of the fuel cell system and drives the vehicle using only a high voltage battery system when the failure exists in the fuel cell system. A temporary stopping step determines a driving state of the vehicle and temporarily stops an operation of the high voltage battery system when it is determined that the driving state is a stop state. A re-driving step re-operates the high voltage battery system to restart the vehicle when the driving state is converted into a start state.
Claims5
A control method for a fuel cell vehicle, the method comprising:
- a failure determining step of determining whether or not a failure exists in a fuel cell system;
- a safe driving step of stopping an operation of the fuel cell system and driving the vehicle using only a high voltage battery system when the failure exists in the fuel cell system;
- a temporary stopping step of determining a driving state of the vehicle and temporarily stopping an operation of the high voltage battery system when it is determined that the driving state is a stop state;
- and
- a re-driving step of re-operating the high voltage battery system to restart the vehicle when the driving state is converted into a start state,
- wherein in the temporary stopping step, an operation of a cooling device for cooling the high voltage battery system among electronic components driven by an auxiliary battery temporarily stops.
