Train control system based on vehicle-vehicle communication takes vehicle-mounted moving unit as the core, it realizes train operation control, breaks through the control mode of CBTC based on access and realizes intelligent operation control through two-way, high-capacity and high-speed vehicle-ground wireless communication, multi-sensor train speed positioning, autonomous collaborative moving block control technology, self-perception and independent decision making.

Vehicle-vehicle communication technology mainly focuses on getting rid of previous control of ZC equipment. ZC, interlock, axle counter, signal and variable responder are eliminated from ground equipment, and the information between train and trackside equipment is mainly exchanged through object controller. Train does not obtain operation information through ZC, and VOBC mainly plans the safe operation path and calculates MA automatically so as to realize quick operation control. Communication among multiple has a higher requirement for communication channel and timeliness.

The train control system based on vehicle-vehicle communication has a simple structure, less ground equipment, and shorter installation and commissioning time to realize higher efficiency and reliability, lower cost, and easier maintenance while ensuring safety. Due to less vehicle-ground communication interface and independence of ground equipment, interconnectivity among different systems can be realized more easily. As the future development direction of rain transit technology, it is imperative to study the train control system based on vehicle-vehicle communication.

The vehicle-vehicle communication system is mainly composed of an intelligent train monitoring system (ITS), intelligent train protection (ITP), intelligent train operation (ITO), object controller (OC) and train management center (TMC) subsystem.
