And when the adjacent front vehicle and the adjacent rear vehicle meet the preset virtual coupling condition, executing a preset virtual coupling process.
The virtual hitching condition may be set according to actual needs, for example, the front car and the rear car may be selected according to a preset hitching plan, and the front car and the rear car operate in a virtual hitching mode in a preset hitching area. Therefore, when the front train and the rear train enter the coupling area, a preset virtual coupling process is executed, and the front train and the rear train are used as a large-marshalled coupling train for operation. And after the coupled train leaves the coupling area, the virtual coupling is released, and the coupled train is divided into a front train and a rear train to be operated independently.
For another example, when the two vehicles enter a preset coupling area according to the position information of the front vehicle and the rear vehicle, the two vehicles may be actively paired according to the position relationship therebetween, and then a preset virtual coupling process may be executed.
The virtual linkage process at least comprises the following steps: and enabling the front vehicle and the rear vehicle to approach to a preset distance threshold value, and establishing vehicle-to-vehicle communication between the front vehicle and the rear vehicle.
