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.

    本发明公开一种商用车电子驻车冗余制动控制系统,包括电子驻车开关、电子驻车模块、三段式翘板开关、冗余制动电磁阀、气源、挂车控制模块和制动气室驻车腔;电子驻车模块包括进气电磁阀、放气电磁阀、继动阀、气压传感器、挂车独立制动电磁阀、保压阀、驻车力度检测电磁阀和ECU处理单元。系统通过三段式翘板开关控制冗余制动电磁阀的开合进而控制电子驻车模块的排放气,以实现电子驻车冗余制动控制动作,进而解决CAN电磁干扰带来的系统失效风险,提高车辆安全性能,特别是智能驾驶的车辆。
