Method and system for controlling air intake of fuel cell vehicle

A method of controlling an air intake of a fuel cell vehicle, comprising:

• calculating, by a controller, a value for basic air intake of a fuel cell based on a driver requirement;
• calculating, by the controller, a value of motor current requirement based on the driver requirement;
• calculating, by the controller, a rate-of-change of the value of motor current requirement;
• calculating, by the controller, a value for supplementary air intake by adding a reflection value based on a speed of the vehicle to a product of the rate-of-change of the value of motor current requirement and a gain value;
• calculating, by the controller, a value for final air intake by adding the value for basic air intake and the value for supplementary air intake;
• and
• operating, by the controller, an air blower of an air intake system of the fuel cell with the value for final air intake.

A method for controlling an air intake of a fuel cell vehicle, comprising

• calculating, by the controller, a value for basic air intake and a value of motor current requirement based on a driver requirement;
• calculating, by the controller, a value for supplementary air intake by multiplying a rate-of-change of the value of motor current requirement by a gain value;
• calculating, by the controller, a value for final air intake by adding the value for basic air intake and the value for supplementary air intake;
• and
• operating, by the controller, an air blower of an air intake system of a fuel cell with the value for final air intake.

A system for controlling an air intake of a fuel cell vehicle, comprising:

• a vehicle accelerator pedal;
• a vehicle drive motor;
• an air blower configured to supply air to a fuel cell;
• and
• a controller configured to operate the air blower by calculating a value for basic air intake and a value of motor current requirement based on an engagement degree of the vehicle accelerator pedal, calculating a value for supplementary air intake by multiplying a rate-of-change of the value of motor current requirement by gain value, calculating a value for final air intake by adding the value for basic air intake and the value for supplementary air intake, and operating the air blower with the value for final air intake.

A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:

• program instructions that calculate a value for basic air intake and a value of motor current requirement based on a driver requirement;
• program instructions that calculate a value for supplementary air intake by multiplying a rate-of-change of the value of motor current requirement by a gain value;
• program instructions that calculate a value for final air intake by adding the value for basic air intake and the value for supplementary air intake;
• and
• program instructions that operate an air blower of an air intake system of a fuel cell with the value for final air intake.
