Abstract: A control method for a train to enter an emergency traction mode is provided. The control method for a train to enter an emergency traction mode is applicable to a traction control system of a train. The method includes the following steps: It is detected whether current emergency traction information satisfies a condition of entering an emergency traction mode. When the current emergency traction information satisfies the condition of entering the emergency traction mode, the train is controlled to enter the emergency traction mode. A hard-wired signal sent by a driver controller is received, and a corresponding operation is performed according to a type of the hard-wired signal.
