The invention discloses a redundant braking system, and belongs to the field of vehicle braking systems. The system is communicated with a main brake system and a wheel cylinder and used for working when the main brake system fails; the system comprises a pressure building assembly, a main redundancy switching assembly and an anti-lock and stability control assembly; the pressure building assembly comprises a liquid storage pool and a power unit; the main redundancy switching assembly comprises a plurality of brake valves; the brake valves switch connection and disconnection of the wheel cylinder and a main brake control circuit or connection and disconnection of the wheel cylinder and a redundant brake control circuit; the anti-lock and stability control assembly comprises a plurality of pressure increasing valves, a plurality of pressure reducing valves and a backflow circuit; the pressure increasing valves control connection and disconnection of the redundant brake control circuit; the pressure reducing valves control connection and disconnection of the backflow circuit; and the backflow circuit is communicated with the brake valves and an oil can; and the brake valves, the pressure increasing valves and the pressure reducing valves are all controlled by an automobile controller. On-off of the wheel cylinder and the main brake system and on-off of the wheel cylinder and an output line are controlled through the main redundancy switching assembly, and independent work of the main brake system and the redundant brake system can be guaranteed.

    本发明公开了冗余制动系统,属于车辆制动系统领域。该系统与主制动系统和轮缸连通,用于在主制动系统失效时工作,该系统包括:建压组件、主冗切换组件、和防抱死及稳定控制组件,建压组件包括蓄液池和动力单元,主冗切换组件包括若干制动阀,制动阀切换轮缸与主制动控制线路或轮缸与冗余制动控制线路的通断,防抱死及稳定控制组件包括若干增压阀、若干减压阀和回流线路,增压阀控制冗余制动控制线路的通断,减压阀控制回流线路的通断,回流线路连通制动阀和油壶,制动阀、增压阀、减压阀均受汽车控制器控制。本发明通过主冗切换组件控制轮缸和主制动系统的通断,以及轮缸和输出线路的通断,能够保证主制动系统和冗余制动系统的独立工作。
