The invention discloses an air supply control method and system for a railway vehicle and the railway vehicle. The control method comprises the steps that a target rotating speed value of a motor at the same moment is calculated according to a pressure value of an air outlet of an air supply unit, and a target pressure rotating speed curve is generated based on the pressure value and the target rotating speed value; and based on the air supply amount and the air storage variable quantity, the air consumption amount of the railway vehicle at the same moment is calculated, based on an air supply amount rotating speed curve and the air consumption amount, the target pressure rotating speed curve is corrected, based on the corrected target pressure rotating speed curve, a frequency converter adjusts the rotating speed of a motor, and the motor drives the air supply unit to work according to the adjusted rotating speed. According to the air supply control method and system for the railway vehicle and the railway vehicle, dynamic adjustment of the air supply amount is achieved, the requirements for the air supply amount of the railway vehicle in different operation periods and the requirements for different air supply amounts of different projects are met, corresponding equipment does not need to be replaced, resource waste is reduced, universality is improved, and miniaturization design of the air supply unit is facilitated.
