Abstract
The present invention provides an automatic train protection method, a vehicle on-board controller and a train based on vehicle-vehicle communication. The method includes: after a present train runs onto a main track, determining an OC with which the present train needs to establish communication; communicating, by the present train, with the OC to obtain train identifiers of all trains within the jurisdiction of the OC; respectively communicating, by the present train, with the train corresponding to each train identifier to obtain current running information of the train corresponding to each train identifier; identifying a front communication neighbor train of the present train; determining that no hidden train exists between the present train and the front communication neighbor train; and calculating current movement authority MA of the present train according to the current position information of the present train and of the front communication neighbor train.
