The invention provides a rail transit vehicle brake control system, a control method thereof and a rail transit vehicle. The system comprises an electronic brake control unit EBCU, an air charging solenoid valve BAV, an air discharging solenoid valve BRV, an emergency brake solenoid valve EBV, a change-over valve CGV, a distribution valve DV, a relay valve RV, a control air cylinder CR and an auxiliary brake air cylinder R. An electronic brake control unit (EBCU) and a distribution valve (DV) receive a brake instruction; and an electronic brake control unit (EBCU) and a distribution valve (DV) respectively carry out micro-electro pneumatic brake and air brake according to the brake instruction. Train braking double-circuit redundancy can be achieved through the two modes of micro-electro-mechanical air braking with the electronic brake control unit (EBCU) as the main body and air braking with the distribution valve (DV) as the main body, and the system reliability and the train running safety are improved.
本申请提供一种轨道交通车辆制动控制系统及其控制方法、轨道交通车辆。所述系统包括:电子制动控制单元EBCU、充风电磁阀BAV、排风电磁阀BRV、紧急制动电磁阀EBV、转换阀CGV、分配阀DV、中继阀RV、控制风缸CR和制动副风缸R。电子制动控制单元EBCU和分配阀DV接收制动指令;电子制动控制单元EBCU和分配阀DV根据所述制动指令分别进行微机电空制动和空气制动。本申请能够通过以电子制动控制单元EBCU为主体的微机电空制动和以分配阀DV为主体的空气制动两种方式实现列车制动双路冗余,提高系统可靠性及列车行车安全。
