The invention discloses a virtual coupling tracking control system and method for a railway vehicle, and the system comprises a wireless communication unit which is used for achieving the automatic communication connection between a front railway vehicle and a rear railway vehicle through a wireless communication technology; the self-sensing identification unit is used for autonomously identifying the front vehicle when the vehicle enters the virtual coupling operation mode and sensing and measuring the running state information of the two vehicles in real time, and the running state information comprises vehicle kinetic parameters, the relative distance between the vehicles, the relative speed and the acceleration information; the relative braking distance calculation unit is used for calculating the relative braking distance of the front and rear vehicles in real time according to the vehicle state information sensed in real time by taking guiding safety as a target; the self-adaptive tracking control unit is used for determining the expected traction braking force of the rear vehicle by adopting a self-adaptive reward and punishment method based on the traction braking force of the front vehicle; and under the constraint condition that the distance between the front vehicle and the rear vehicle is always larger than the relative braking distance, the expected traction braking force is used for controlling the rear vehicle to run in a self-adaptive tracking mode.
