The invention belongs to an electromechanical braking system in the technical field of vehicles, and discloses a driving and parking braking torque mutual coupling redundancy electromechanical braking system which comprises a brake assembly, an MGU and shell, a driving braking motor and gear reducing mechanism assembly, a gear system bearing support and an ECU controller assembly. The service braking gear reduction mechanism assembly comprises a service braking first-stage reduction gear train mounting mechanism, a second-stage reduction gear train mounting mechanism and a bearing, and the parking braking gear reduction mechanism assembly comprises a parking first-stage reduction worm and gear mechanism, a second-stage reduction worm and gear mechanism and a mounting bearing. The braking torque of the driving braking and the braking torque of the parking braking are mutually coupled, the two systems can share the braking output gear shaft assembly, the driving braking and the parking braking can be independently operated, and meanwhile the parking braking can assist the driving braking when needed. By means of the design, the safety and reliability of the braking system are improved.
