The method comprises: receiving an emergency unlocking request signal; according to the emergency unlocking request signal, determining whether a zero-speed state, an emergency unlocking permission state and a vehicle door opening permission state of a railway vehicle are valid, wherein the zero-speed state is used for representing that the railway vehicle is in a stopped state, the emergency unlocking permission state is used for representing that there is an emergency event in the railway vehicle, and the vehicle door opening permission state is used for representing that the railway vehicle is located at a position where stopping is permitted; and if the zero-speed state, the emergency unlocking permission state and the vehicle door opening permission state are all valid, generating a vehicle door unlocking signal.
