Abstract

A communication system and method receive, at an energy management system disposed onboard a vehicle system formed from a lead vehicle and one or more remote vehicles, trip data that represents one or more characteristics of an upcoming trip of the vehicle system along a route. A selected portion of the trip data is communicated from the energy management system to a distributed power system also disposed onboard the vehicle system. The selected portion includes identifying information and one or more orientations of the one or more remote vehicles. Using the distributed power system, communication links between the lead vehicle and the one or more remote vehicles are established using the identifying information and the one or more orientations.

First claim

What is claimed is:

1 . A system comprising:
a lead powered vehicle including a first directional sensor that is configured to output a first directional signal indicative of a first heading of the lead powered vehicle; a remote powered vehicle including a second directional sensor that is configured to output a second directional signal indicative of a second heading of the remote powered vehicle, wherein the lead powered vehicle controls operation of the remote powered vehicle; and a heading determination unit having a communication interface and a controller, wherein the communication interface is configured to receive the first and second directional signals, and wherein the controller is configured to determine an orientation for the second heading based on the first and second directional signals.

2 . The system of claim 1 , wherein the heading determination unit is onboard the lead powered vehicle.

3 . The system of claim 1 , wherein the heading determination unit is remotely located from the lead and remote powered vehicles.

4 . The system of claim 1 , wherein the heading determination unit is configured to compare the first directional signal with the second directional signal to determine the orientation of the second heading.

5 . The system of claim 1 , wherein at least one of the first or second directional sensors comprises a digital compass.

6 . The system of claim 1 , wherein at least one of the first or second directional sensors comprises a global positioning system (GPS) unit.

7 . The system of claim 1 , wherein the remote powered vehicle is directly coupled to the lead powered vehicle.

8 . The system of claim 1 , wherein at least one other vehicle is connected between the lead powered vehicle and the remote powered vehicle.

9 . The system of claim 1 , wherein the lead powered vehicle is a lead locomotive on a track, and wherein the remote powered vehicle is a remote locomotive on the track.

10 . A method comprising:
disposing a first directional sensor onboard a lead powered vehicle; outputting, from the first directional sensor, a first directional signal indicative of a first heading of the lead powered vehicle; disposing a second directional sensor onboard a remote powered vehicle that is controlled by the lead powered vehicle; outputting, from the second directional sensor, a second directional signal indicative of a second heading of the remote powered vehicle; receiving the first and second directional signals at a heading determination unit; and determining, by the heading determination unit, an orientation for the second heading based on the first and second directional signals.

11 . The method of claim 10 , further comprising disposing the heading determination unit onboard the lead powered vehicle.

12 . The method of claim 11 , further comprising remotely locating the heading determination unit from the lead and remote powered vehicles.

13 . The method of claim 10 , wherein the determining comprises comparing the first directional signal with the second directional signal to determine the orientation of the second heading.

14 . The method of claim 10 , wherein at least one of the first or second directional sensors comprises a digital compass.

15 . The method of claim 10 , wherein at least one of the first or second directional sensors comprises a global positioning system (GPS) unit.

16 . The method of claim 10 , further comprising directly coupling the remote powered vehicle to the lead powered vehicle.

17 . The method of claim 10 , further comprising connecting at least one other vehicle between the lead powered vehicle and the remote powered vehicle.

18 . The method of claim 10 , wherein the lead powered vehicle is a lead locomotive on a track, and wherein the remote powered vehicle is a remote locomotive on the track.

19 . A heading determination unit comprising:
a communication interface; and a controller operably coupled to the communication interface and having at least one processor, wherein the communication interface is configured to receive a first directional signal from a first directional sensor of a lead powered vehicle, the first directional signal indicative of a first heading of the lead powered vehicle, wherein the communication interface is configured to receive a second directional signal from a second directional sensor of a remote powered vehicle, the second directional signal indicative of a second heading of the remote powered vehicle, wherein the lead powered vehicle controls operation of the remote powered vehicle, and wherein the controller is configured to determine an orientation for the second heading based on the first and second directional signals.

20 . The heading determination unit of claim 19 , wherein the communication interface and the controller are disposed on board one of the lead powered vehicle and the remote powered vehicle, and each of the first directional sensor and the second directional sensor is one of a respective digital compass or a respective global positioning system (GPS) unit.
