System, method and computer readable media for operating a distributed power train
First Claim
1. A system comprising:
- a controller configured to issue commands to control operation of a remote powered unit of a powered vehicle system based on a trip plan that dictates one or more operations of the powered vehicle system as the powered vehicle system travels along a route, the controller further configured to determine a location of the remote powered unit along the route in response to an identified communications loss between the remote powered unit and a lead powered unit of the powered vehicle system, wherein the controller is configured to determine a designated operation of the remote powered unit that is associated with the location of the remote powered unit in the trip plan and to control operation of the remote powered unit based on the designated operation when the communications loss is identified.

Abstract
An embodiment of the invention for conducting a distributed power train operation, comprises a controller at the remote unit for issuing commands to control the operation of the remote unit on a track, and responsive to a communication loss between the lead unit and the remote unit. A memory, accessible by the controller, comprises data relative to a track profile including a plurality of geographical coordinates of the track and data relative to one or more throttle positions or braking operations for the remote unit that are associated with the geographical coordinates. The controller receives data relative to geographical coordinates of the remote unit and upon a detection of the communication loss, the controller compares the geographical coordinates of the remote unit to the track profile geographical coordinates and issues one more commands associated with the operation of the remote unit.

12. A system comprising:
a controller configured to be disposed on-board a remote powered unit of a powered vehicle system and to issue commands to control operation of the remote powered unit, the controller also configured to determine a location of the remote powered unit along a route being traveled by the powered vehicle system and to determine an operation of the remote powered unit from a trip plan of the powered vehicle system and based on the location of the remote powered unit, wherein the controller is configured to take over control of the operation of the remote powered unit from the lead powered unit and to implement the operation determined from the trip plan in response to identification of a communications loss between the lead powered unit and the remote powered unit. - View Dependent Claims (13, 14, 15)

23. A method comprising:
-
controlling one or more operations of a remote powered unit of a powered vehicle system from a lead powered unit of the powered vehicle system as the powered vehicle system travels along a route according to a trip plan, the trip plan including one or more designated operations of the powered vehicle system; identifying a communications loss between the lead powered unit and the remote powered unit, the communications loss preventing the lead powered unit from controlling the one or more operations of the remote powered unit; determining a location of the remote powered unit along the route; and issuing a command to control the one or more operations of the remote powered unit in response to the communications loss that is identified, the command based on one or more designated operations of the trip plan and on the location of the remote powered unit. - View Dependent Claims (24, 25, 26)

27. A method comprising:
-
identifying a communications loss between a remote powered unit and a lead powered unit of a powered vehicle system, the lead powered unit controlling one or more operations of the remote powered unit prior to the communications loss that is identified; determining at least one of a location or a direction of movement of the remote powered unit; selecting a designated operation from a trip plan based on the at least one of the location or the direction of movement, the trip plan including a plurality of the designated operations associated with a plurality of different locations or a plurality of different directions of movement as the powered vehicle system travels along a route; and issuing at least one command to control movement of the remote powered unit during the communications loss, said at least one command based on the designated operation that is selected from the trip plan.
