Method and device for setting coupling area of virtual coupling system

The invention discloses a method for setting a coupling area for a virtual coupling system, which comprises the following steps of: dynamically coupling rail transit trains, enabling two autonomously running trains not to be in direct contact, and finishing the coupling action of a virtual coupling formation through the processes of coupling application, coupling information interaction and coupling confirmation in the simultaneous running process of the trains. Rail transit trains are statically coupled, the trains or train formations needing to be coupled stop at a platform area, the trains applying for coupling slowly approach the static trains or formations according to a relative braking distance model, and in the coupling application, coupling information interaction and coupling confirmation process, the trains or the formations in the train formations do not need to be coupled. And the train applying for coupling is virtually coupled to the coupling action of the formation. The method has the advantag
