The invention discloses a direction control system and method in the running process of a rail transit vehicle and the vehicle. The direction control system comprises direction control units arranged in a first-end cab and a second-end cab respectively. The direction control unit comprises a forward instruction activation branch and a backward instruction activation branch which are connected in parallel; the forward instruction activation branch comprises a cab occupying relay normally-open contact, a forward relay normally-open contact, a backward instruction relay normally-closed contact, a zero-speed relay normally-open contact and a forward instruction relay coil which are connected in series; and the backward instruction activation branch comprises a backward relay normally-open contact, a forward instruction relay normally-closed contact, a zero-speed relay normally-open contact and a backward instruction relay coil which are connected in series with the cab occupying relay normally-open contact. The forward instruction activation branch and the backward instruction activation branch can achieve self-locking, and it is guaranteed that the running direction of the vehicle is accurate and reliable.
本发明公开了一种轨道交通车辆运行过程中的方向控制系统、方法及车辆,包括:分别设置在第一端司机室和第二端司机室中的方向控制单元;方向控制单元包括并联连接的前向指令激活支路和后向指令激活支路;前向指令激活支路包括:串联连接的司机室占有继电器常开触点、前向继电器常开触点、后向指令继电器常闭触点、零速继电器常开触点和前向指令继电器线圈;后向指令激活支路包括:与司机室占有继电器常开触点串联连接的后向继电器常开触点、前向指令继电器常闭触点、零速继电器常开触点和后向指令继电器线圈。本发明的前向指令激活支路和后向指令激活支路均能够实现自锁,保证车辆运行方向的准确可靠。
