Claim 4:
5. The method of claim 1, wherein the step S4 comprises the following process:
when a to-leave vehicle is located at a tail of the formation, the to-leave vehicle slows down to increase a following distance to leave the formation, while the emergency flashers of the to-leave vehicle are turned on to indicate to vehicles behind to slow down earlier to avoid collision; the GIS server updates the formation information;
when the to-leave vehicle is located in a middle of the formation, when there is safe space to change lanes in a target lane, the to-leave vehicle sends formation-leaving information to the lead vehicle and the vehicles behind the to-leave vehicle and the formation-leaving information also directs the to-leave vehicle to change lanes to leave the formation, then information is sent to the lead vehicle to indicate that the to-leave vehicle has left the formation; after the formation receives the information, an instruction is sent to the vehicles behind the leaving vehicle in the formation to direct the vehicles to travel in an original safe distance, and at the same time, the formation information is updated and uploaded to the GIS server;
when the to-leave vehicle is the lead vehicle, the lead vehicle informs, by sending information or making voice calls, the vehicles behind that the lead vehicle is leaving the formation; the vehicle behind the lead vehicle becomes a new lead vehicle to continue leading the formation and updates the formation information in synchronization with the GIS server in time.
