The invention discloses a helicopter wheel brake control system and method, and belongs to the technical field of helicopter wheel brake control. The control system comprises a brake control box, a brake instruction sensor, a high-speed switch valve, an airplane wheel parking pressure retaining valve and a brake pressure sensor, the brake instruction sensor, the high-speed switch valve, the airplane wheel parking pressure retaining valve and the brake pressure sensor are electrically connected with the brake control box, and the brake control box collects instruction signals through the brake instruction sensor and collects brake pressure signals through a brake port pressure sensor. A normal brake signal and a parking signal are output through the high-speed switch valve and the airplane wheel parking pressure retaining valve; an oil inlet and an oil return port of the high-speed switch valve are connected with the energy assembly through a pipeline, and a brake port of the high-speed switch valve connects the airplane wheel parking pressure retaining valve with the brake sensor through the change-over valve; an oil inlet of the airplane wheel shutdown pressure retaining valve is connected with the energy assembly through a pipeline, and a brake port of the airplane wheel shutdown pressure retaining valve is connected with the brake sensor through the change-over valve. According to the invention, the helicopter can be stably and reliably braked after landing, and the reliability and the safety of an airplane wheel braking system are improved.
