The invention discloses a hydraulic servo boosting system, and belongs to the technical field of automobile braking. The problem that an existing braking assisting system is not sufficient in electronic control is solved. A hydraulic booster of the hydraulic servo boosting system comprises a braking oil cylinder and a low-pressure energy accumulator. A boosting cavity, a treading sense simulating cavity and an oil liquid compensation cavity are formed between a braking piston and a push rod assembly. A hydraulic servo mechanism comprises a high-pressure energy accumulator, a liquid storage tank and an oil pump. A first oil inlet pipeline is communicated between the high-pressure energy accumulator and the boosting cavity. A second oil inlet pipeline is communicated between the high-pressure energy accumulator and the treading sense simulating cavity. A first oil returning pipeline is communicated between the liquid storage tank and the boosting cavity. A second oil returning pipeline is communicated between the liquid storage tank and the treading sense simulating cavity. An electronic control unit is connected with an oil pump and a displacement sensor and can control the oil pump to work according to signals fed back by the displacement sensor and control the first oil inlet pipeline, the second oil inlet pipeline, the first oil returning pipeline and the second oil returning pipeline to be opened and closed.
