A dual-redundancy electronic brake boosting system comprises a pedal module U1 and a boosting module U2, and the pedal module U1 comprises a linkage pedal, a first simulation main cylinder and a second simulation main cylinder; the linkage pedal is connected with the first simulation main cylinder and the second simulation main cylinder through two pipelines, a first pedal sensing sensor is arranged on the pipeline between the first simulation main cylinder and the linkage pedal, and a second pedal sensing sensor is arranged on the pipeline between the second simulation main cylinder and the linkage pedal. The linkage pedal pushes the two simulation main cylinders to establish hydraulic pressure at the same time, and the first pedal sensor and the second pedal sensor send pedal travel signals to the ECU controller; the power assisting module U2 is connected with the U1 through a pipeline, the power assisting module U2 is externally connected with the ESC, and the ESC communicates with a brake; and a double-loop independent design is adopted, mutual redundancy is realized, a multi-stage backup capability is realized, and the safety performance of the system is greatly improved.
