The invention discloses an electric control system for trailer brake control, which is connected to a shaft control unit of a tractor and an air supply circuit of a trailer, and comprises a valve assembly arranged on the air supply circuit of the trailer and used for controlling the on-off of the air supply circuit according to a brake signal; the electronic control unit is electrically connected to the valve assembly and used for outputting current to control the valve assembly to act according to the brake signal transmitted by the shaft control unit; the hard wire is connected to the shaft control unit and the electronic control unit, or/and connected to the shaft control unit and the valve assembly and used for transmitting a brake signal to the valve assembly; and the bus is connected to the electronic control unit and the shaft control unit and is used for transmitting a brake signal to the electronic control unit. The system has the beneficial effects that the bus braking signal and the hard wire braking signal are transmitted through the bus and the hard wire respectively, multi-path redundant transmission is achieved, it can still be ensured that the trailer can receive the braking signal when a certain line breaks down, and the braking reliability of the trailer is improved.

    本申请公开了挂车制动控制的电控系统,连接于牵引车的轴控制单元以及挂车的供气气路,包括:阀组件,设置于挂车的供气气路,用于根据制动信号控制供气气路通断;电子控制单元,电性连接于阀组件,用于根据轴控制单元传递的制动信号输出电流控制阀组件动作;硬线,连接于轴控制单元以及电子控制单元,或/和,连接于轴控制单元以及阀组件,用于向阀组件传递制动信号;总线,连接于电子控制单元以及轴控制单元,用于向电子控制单元传递制动信号。本申请的有益效果:利用总线与硬线分别传输总线制动信号以及硬线制动信号,多路冗余传输,在某一线路出现故障时,仍能确保挂车能够接收到制动信号,提高挂车制动的可靠性。
