A method for trains to establish a virtual coupling (VC) operation mode, which includes: successively determining whether adjacent preceding and following trains on a same line meet initial conditions and formation conditions of the VC; and performing VC on both trains meeting the initial conditions and formation conditions, and determining the VC of all trains on the line through the above determination method to obtain an overall VC. The method further including controlling operation of a leading train in the overall VC according to driving permission of the VC, and controlling operation of each of remaining following trains based on communication with the corresponding adjacent preceding train in combination with the following train's own driving information. An establishment process of forming a VC operation mode, thereby improving efficiency of train transportation and flexibility of organization and scheduling.

A method and a system are provided for data management in a transport device, in particular in a train. In a first comparison, a first count value stored in a first control device is compared with a count value stored in a second control device. In a second comparison, a count value selected from the first and second count values on the basis of a result of the first comparison is compared with a control count value stored in a safety device. On the basis of a result of the second comparison, control data stored in the safety device and associated with the control count value are acquired by the first or second control device.

A control system includes a controller configured to control communication between or among plural vehicle devices that control operation of a vehicle via a network that communicatively couples the vehicle devices. The controller also is configured to control the communication using a data distribution service (DDS) and with the network operating as a time sensitive network (TSN). The controller is configured to direct a first set of the vehicle devices to communicate using time sensitive communications, a different, second set of the vehicle devices to communicate using best effort communications, and a different, third set of the vehicle devices to communicate using rate constrained communications.

A vehicle control system includes a controller configured to control communication between or among plural vehicle devices that control movement of a single vehicle system or a multi-vehicle system via a network that communicatively couples the vehicle devices.

Systems and methods for timeline representations of trip phases of a mobile vehicle are described. A method may include receiving operational events associated with a voyage of the mobile vehicle. The operational events may include events such as take-off, landing, door open, door closed, engine started, or other types of operational events. Each operational event may have a corresponding event time at which the event occurred or was detected. The method may include receiving network metric values for network communication metrics associated with a network service on the mobile vehicle. Each network metric value may have a corresponding value time at which the metric was measured or detected. The operational events and network communication metrics may be displayed in a time-aligned manner on a timeline representation over a time range indicated by a user.

A rail train brake control system, comprising: a single vehicle brake control unit, a train brake control unit, a traction control unit and a communication control unit; the single vehicle brake control unit is provided in each vehicle of the rail train, the train brake control unit and the communication control unit are provided in the vehicles at both ends of the rail train, and the traction control unit is disposed in motor vehicles of a plurality of vehicles; and the single vehicle brake control unit, the train brake control unit, the traction control unit and the communication control unit implement communication by means of the gateway. The system can realize flexible marshalling of a train. Further disclosed is a train comprising the train brake control system.

A communication apparatus is mounted on a train and forms a train communication system together with a system control apparatus that generates control frames including general and low-latency frames. The communication apparatus includes: a general transfer processing unit that stores the general frame; a low latency transfer processing unit that stores the low-latency frame, the low latency frame requiring transferring with lower latency than the general frame; a frame identification unit that identifies priority of the control frame and outputs the control frame to the general transfer processing unit or the low latency transfer processing unit based on a priority setting table indicating the priority of the control frame and set in the identification unit; an output control unit that preferentially transfers the low-latency frame over the general frame; and a control unit that modifies the priority setting table.

A device operatively couples a tractor ABS controller with TABS controllers in units towed by the tractor. A PLC interface circuit of the device communicates messages received from a PLC network of the towed units to a CAN network of the tractor via a CAN interface circuit. The device may also rebroadcast messages received from the PLC network back onto the PLC network, and may also wirelessly broadcast messages received from the PLC network back onto a wireless network. The device receives messages from the towed units at a message rate, determines a quantity of towed units from the message rate, and communicates the determined quantity of towed units on the CAN network of the tractor. The device receives messages indicating towed unit identification (ID) information, determines a quantity of towed units from the towed unit ID information, and communicates the determined quantity of towed units on the CAN network.

A system and method includes a first control system having one or more processors onboard a lead vehicle of a vehicle system that includes the lead vehicle and a remote vehicle. The second control system automatically restricts movement of the vehicle system based on a location of the vehicle system. The processors detect a signal instance of an operator actuating an input device, and communicate a vehicle information request message to the second control system. The second control system communicates a list of vehicle identifiers, that includes a vehicle identifier associated with the remote vehicle, to the processors. The processors communicate a wireless linking message, including a request to establish a communication link, to the remote vehicle based on the vehicle identifier associated with the remote vehicle.
