The invention provides an electronic mechanical braking system which comprises four wheel end braking control modules, each wheel end braking control module is provided with two paths of redundant power supply input, namely a first power supply input line and a second power supply input line, and each wheel end braking control module comprises a wheel end braking controller. The wheel end brake controller selects two redundant power supplies to input one of the redundant power supplies as a main power supply, and the other redundant power supply is used as a backup power supply; the wheel end brake controller comprises a power supply gating switching module, the power supply gating switching module comprises a main power supply input line module and a backup power supply input line module, the main power supply input line module is gated to drive the wheel end brake module when main power supply is effective, and the backup power supply input line module is gated to drive the wheel end brake module when the main power supply input line module fails. The wheel end brake controller can be automatically switched to the backup power supply input line module to drive the wheel end brake module.
本发明提供一种电子机械制动系统,包括有四个轮端制动控制模块,每个所述轮端制动控制模块具备两路冗余供电电源输入,分别为供电输入线路一和供电输入线路二,轮端制动控制模块包含一个轮端制动控制器,一个制动电机以及对应的机械制动装置,轮端制动控制器选择两路冗余供电电源输入其中一路作为其主供电,另一路作为其备份供电;轮端制动控制器中包含一个供电电源选通切换模块,供电电源选通切换模块包括有主供电输入线路模块和备份供电输入线路模块,在其主供电有效时选通使用主供电输入线路模块驱动轮端制动模块,当其主供电输入线路模块故障时,轮端制动控制器可自主地切换到其备份供电输入线路模块驱动轮端制动模块。
