The invention discloses an electronic parking redundant braking control system for a commercial vehicle. The electronic parking redundant braking control system comprises an electronic parking switch, an electronic parking module, a three-section rocker switch, a redundant braking electromagnetic valve, an air source, a trailer control module and a braking air chamber parking cavity. The electronic parking module comprises an air inlet electromagnetic valve, an air outlet electromagnetic valve, a relay valve, an air pressure sensor, a trailer independent braking electromagnetic valve, a pressure retaining valve, a parking force detection electromagnetic valve and an ECU processing unit. The system controls the opening and closing of the redundant braking electromagnetic valve through the three-section rocker switch so as to control the exhaust of the electronic parking module, so that the electronic parking redundant braking control action is realized, the system failure risk caused by CAN electromagnetic interference is solved, and the safety performance of the vehicle, particularly the intelligent driving vehicle, is improved.
