A system and method for suppressing serpentine instability of a railway vehicle, comprising a serpentine warning and control module for determining whether a bogie is in a state of serpentine instability; a traction motor speed control system for controlling a rotation speed of a traction motor according to a determination from the serpentine warning and control module; a signal output end of the serpentine warning and control module is connected with the traction motor speed control system. In the present disclosure, it extracts the serpentine characteristic wave from the transverse acceleration of the bogie and calculates the vibration non-linear index according to the extracted serpentine non-linear characteristic to judge whether the bogie is in a state of serpentine instability, and controls a direct torque of the traction system through the DTC control module. The existing transverse control of the train can only reduce the transverse vibration of the train and cannot eliminate the serpentine instability. However, the present disclosure can control the traction motor to reduce the speed and eliminate the serpentine instability.
