Method and system for virtually coupled train set control

A method for virtually coupled train set (VCTS) control, comprising:

• acquiring an actual state for a current cycle of each train unit in VCTS;
• determining whether to execute a backup control strategy based on the actual state for the current cycle of each train unit and a target state sequence for a first predetermined number of cycles before the current cycle, to obtain a first determination result;
• wherein the backup control strategy comprises a control strategy for tracking a recommended driving curve by a first train unit and a control strategy for tracking a i-th train unit by a (i+1)-th train unit, wherein a value of i is greater than or equal to 1;
• executing the backup control strategy to control each train unit, if the first determination result is yes;
• executing following operations, if the first determination result is no:
• determining whether synchronization of each train unit in the VCTS meets a predetermined condition, to obtain a second determination result;
• calculating a target state sequence for the current cycle of each train unit based on a position according to the actual state for the current cycle of each train unit, if the second determination result is yes;
• calculating the target state sequence for the current cycle of each train unit by using a synchronization relationship according to the actual state for the current cycle of each train unit, if the second determination result is no;
• controlling each train unit according to the target state sequence for the current cycle of each train unit, respectively.
