Latest Patents

Junguo Sun's latest patents include an automatic train protection method, a vehicle on-board controller, and a train based on vehicle-vehicle communication. This invention provides a comprehensive method for automatic train protection, which includes determining communication needs with an operational control (OC) after a train runs onto a main track. The method facilitates communication with the OC to obtain identifiers of all trains within its jurisdiction, allowing for the collection of current running information from each identified train. Furthermore, it identifies the front communication neighbor train and ensures that no hidden trains exist between the present train and this neighbor, ultimately calculating the current movement authority (MA) based on the positions of both trains.

Another notable patent is a route resource controlling method, along with an intelligent vehicle on-board controller and object controller. This method determines a route search extension distance based on the current location and speed of the train. It establishes the farthest distance that is expected to be safe for operation, while also identifying the required link and route resources.
