The invention belongs to the technical field of vehicles, and discloses an engineering vehicle braking system, an engineering vehicle braking method and an engineering vehicle. According to the engineering vehicle braking system, the input end of a hydraulic pump communicates with an oil tank, a liquid outlet in a shuttle valve can communicate with a first liquid inlet or a second liquid inlet, and the liquid outlet communicates with a first braking cavity of a drive axle brake; a first port or a second port in the foot brake valve can be communicated with a third port, the third port is communicated with a first liquid inlet of the shuttle valve, the first port is communicated with the output end of the hydraulic pump, the second port is communicated with an oil tank, and a fourth port or a fifth port in the proportional pressure reducing valve can be communicated with a sixth port. The sixth port is communicated with the second liquid inlet of the shuttle valve, the fourth port is communicated with the output end of the hydraulic pump, the fifth port is communicated with the oil tank, and a pipeline between the first port of the foot brake valve and the hydraulic pump is communicated with the energy accumulator. The engineering vehicle braking system is fast in braking response and small in demand for the volume of the energy accumulator.
