The invention belongs to the technical field of automobile power-assisted braking, and relates to a hydraulic power-assisted braking system. The hydraulic power-assisted braking system comprises an electronic control unit, a motor, a roller screw mechanism, a power assisted cylinder, an angle sensor, an oil cup, a three-cavity braking main cylinder, a braking pedal and a push rod. The electronic control unit is connected with the motor. The motor is connected with the roller screw mechanism. The roller screw mechanism is in rigid connection with a power assisted cylinder piston in the power assisted cylinder. The power assisted cylinder is connected with the three-cavity braking main cylinder through an oil way and connected with the oil cup through an oil way. The braking pedal is in rigid fastening connection with the push rod. The push rod is inserted into the three-cavity braking main cylinder. The three-cavity braking main cylinder comprises a first cavity of the three-cavity braking main cylinder, a second cavity of the three-cavity braking main cylinder and a third cavity of the three-cavity braking main cylinder. By means of the hydraulic power-assisted braking system, the rotation of the motor is converted into the transverse movement of the piston, and the manual effect can be developed under the condition that the motor loses efficacy; the pedal feeling is simulated through compressed springs, and the good pedal feeling can be provided for a driver; the hydraulic power-assisted braking system can be freely arranged on a whole vehicle and is flexible in structure.
