The invention provides a redundant power supply system of an electronic mechanical braking system. The redundant power supply system comprises a power supply module, the power supply switching module is connected with the power supply modules through power supply lines, and power supply switching is controlled through the power supply switching module; the wheel end braking control modules are correspondingly connected with the power supply switching modules through power supply lines respectively, and the wheel end braking control modules control braking of corresponding wheels; and the controller module and the control module are respectively connected to a power supply line of the power supply module. On the premise of ensuring that each component unit in the system obtains redundant power supply, a redundant power supply switching circuit in the wheel end brake control module is canceled, the design of the wheel end brake control module is simplified, the number of power supply wire harnesses is reduced, the wire harness cost is reduced, and the spatial arrangement of the wheel end brake control module is also facilitated.
本发明提供一种电子机械制动系统冗余供电系统,包括:电源模块:通过电源模块提供电源;供电切换模块:所述供电切换模块通过供电线路分别电源模块连接,通过供电切换模块控制电源切换;轮端制动控制模块:所述轮端制动控制模块通过供电线路分别与供电切换模块对应连接,轮端制动控制模块控制对应车轮的制动;控制器模块:控制模块分别连接在电源模块的供电线路上。在保证系统中各组成单元获得冗余供电的前提下,取消轮端制动控制模块中的冗余电源切换电路,简化轮端制动控制模块设计,减少供电线束的数量,降低线束成本,也有利于轮端制动控制模块的空间布置。
