Classification: CPC B | IPC B

Claim 0:
1. A method for controlling train formation tracking, comprising:
obtaining a current distance between a first train and a second train in a train formation by means of real-time measurement performed by a lidar sensor mounted on the first train, wherein the first train is adjacent to the second train and located behind the second train;
determining a target tracking mode of the first train based on the current distance between the first train and the second train in the train formation with the target tracking mode being selected from a speed tracking mode, a distance tracking mode and a braking mode; wherein the speed tracking mode is a mode in which a maximum safe speed of the first train with respect to the second train is tracked as a control target through a speed tracking controller, the distance tracking mode is a mode in which an ideal distance between the first train and the second train is tracked as a control target through a distance tracking controller without triggering the braking mode of the first train, and the braking mode is a mode in which a braking is applied at a maximum braking rate of the first train; and
tracking the second train, by the first train based on the target tracking mode.
