The invention relates to the technical field of railway vehicles, and provides a railway vehicle external lighting control circuit and a railway vehicle. The circuit comprises a first branch circuit and a second branch circuit which are connected in parallel between the positive electrode and the negative electrode of a power supply; the first branch is connected in series with a first contact of a slave control relay, a first contact of a forward relay and a headlamp control contactor coil; the second branch is connected in series with a main control relay first contact, a headlamp switch and a headlamp group, and the second branch is also provided with a headlamp control contactor contact which is connected in parallel with the main control relay first contact and the headlamp switch; and in response to a backward operation instruction of the master control end vehicle, a slave control relay first contact of the slave control end vehicle and a forward relay first contact of the slave control end vehicle are closed, a headlamp control contactor coil of the slave control end vehicle is electrified, a headlamp control contactor contact of the slave control end vehicle is closed, and a headlamp group of the slave control end vehicle is opened. According to the invention, automatic control of the vehicle headlamp group at the slave control end is realized.
本发明涉及轨道车辆技术领域,提供一种轨道车辆外部照明控制电路及轨道车辆,该电路包括:并联在电源正负极之间第一支路和第二支路;所述第一支路上串联有从控继电器第一触点、前向继电器第一触点和前照灯控制接触器线圈;第二支路上串联有主控继电器第一触点、前照灯开关和前照灯组,第二支路上还设有与主控继电器第一触点和前照灯开关并联的前照灯控制接触器触点;响应主控端车辆的后向操作指令,从控端车辆的从控继电器第一触点和从控端车辆的前向继电器第一触点闭合,从控端车辆的前照灯控制接触器线圈得电,从控端车辆的前照灯控制接触器触点闭合,开启从控端车辆的前照灯组。本发明实现了从控端车辆前照灯组的自动控制。
