The invention provides a wheel type take-off and landing unmanned aerial vehicle brake control method and system. The method comprises the steps that the taxiing lift force of an unmanned aerial vehicle is calculated; the pneumatic pitching moment of the unmanned aerial vehicle is calculated; based on the skating lift force, the pneumatic pitching moment, parameters of the unmanned aerial vehicle and a main wheel supporting force formula of the unmanned aerial vehicle, main wheel supporting force of the ground to main wheels of the unmanned aerial vehicle is obtained; obtaining the critical braking torque of the unmanned aerial vehicle based on the main wheel supporting force; and setting the brake instruction quantity of the unmanned aerial vehicle based on the critical brake torque, so that the brake instruction quantity of the unmanned aerial vehicle can be accurately set during takeoff and taxiing or landing and taxiing of the unmanned aerial vehicle, and the problems that the brake instruction quantity of an existing wheel type takeoff and landing unmanned aerial vehicle is inaccurate in control and cannot be accurately controlled are solved. Therefore, the problem that the braking distance is too long or the unmanned aerial vehicle swings laterally is solved.
