The invention belongs to the technical field of vehicle braking and provides a hydraulic power-assisted braking system, an exhaust method of the hydraulic power-assisted braking system and a vehicle. The hydraulic power-assisted braking system comprises a power-assisted oil cylinder, a system oil unit, an axle braking unit and an exhaust oil inlet way, the power-assisted oil cylinder comprises a system oil working cavity and a braking oil working cavity, and the system oil unit comprises a power-assisted working oil way and a reversing control valve. The reversing control valve is connected between the power-assisted working oil way and the system oil working cavity and used for controlling oil feeding and returning of the system oil working cavity, the axle braking unit is connected with the braking oil working cavity through the first on-off control element, and the exhaust oil inlet way is connected between the axle braking unit and a pressure oil way of the power-assisted working oil way. And a second on-off control element is arranged on the exhaust oil inlet path. The exhaust debugging process of the system can be completed through one-man operation, the labor cost is reduced, and meanwhile operation is simpler.
