AUTOMATIC TRAIN PROTECTION METHOD BASED ON VEHICLE-VEHICLE COMMUNICATION, CORRESPONDING VEHICLE ON-BOARD CONTROLLER AND TRAIN COMPRISING SUCH A CONTROLLER

摘要

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 (S21); communicating, by the present train, with the OC to obtain train identifiers of all trains within the jurisdiction of the OC (S22); respectively communicating, by the present train, with the train corresponding to each train identifier to obtain current running information corresponding to each train identifier (S23); identifying a front communication neighbor train of the present train (S24); determining that no hidden train exists between the present train and the front communication neighbor train (S25); 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 (S26).
