Abstract

A method includes determining whether use of an energy management system (EMS) associated with a vehicle traveling in a transportation network is allowed within a region of the transportation network. The EMS obtains a trip plan for the vehicle that designates operational settings of the vehicle as a function of at least one of distance or time along a trip of the vehicle. The method also includes determining whether the EMS is being used by the vehicle when the vehicle is within the region, and sending a message to an off-board location when the EMS is not being used by the vehicle within the region.

Claims

1. A method comprising:

determining whether use of an energy management system (EMS) associated with a vehicle traveling in a transportation network is allowed within a region of the transportation network, wherein the EMS obtains a trip plan for the vehicle that designates operational settings of the vehicle as a function of at least one of distance or time along a trip of the vehicle, and wherein the trip plan designates the operational settings for the vehicle in order to reduce at least one of fuel consumed or emissions generated during the trip relative to traveling according to another plan;

determining whether the EMS is being used by the vehicle when the vehicle is within the region using a computer; and

sending a message to an off-board location when the EMS is not being used by the vehicle within the region using the computer.

2. The method of claim 1, wherein sending the message to the off-board location comprises indicating to the off-board location a reason why the EMS is not being used by the vehicle within the region.

3. The method of claim 1, wherein determining whether use of the EMS is allowed within the region comprises determining a location of the vehicle within the transportation network and within the region.

4. The method of claim 1, wherein determining whether use of the EMS is allowed within the region comprises comparing a location of the vehicle within the transportation network to a route chart of the EMS to determine whether the region is an energy management region.

5. The method of claim 1, wherein determining whether the EMS is being used by the vehicle comprises determining whether an operator is following at least one command instruction within a predetermined threshold.

6. The method of claim 1, wherein determining whether the EMS is being used by the vehicle comprises determining whether the trip plan of the EMS is being followed by the vehicle when the vehicle is within the region.

7. The method of claim 1, wherein sending the message to the off-board location comprises waiting a predetermined amount of time after the vehicle has entered the region to send the message.

8. The method of claim 1, further comprising displaying to an operator of the vehicle that the EMS is allowed for use but is not being used when the vehicle is within the region.

9. The method of claim 1, further comprising prompting an operator of the vehicle to initiate use of the EMS when the EMS is allowed for use and the vehicle is within the region.

10. The method of claim 1, wherein sending the message to the off-board location comprises indicating to the off-board location that the EMS is allowed for use within the region.

11. The method of claim 1, wherein sending the message to the off-board location comprises indicating to the off-board location that the EMS is not being used by the vehicle within the region because of ambient conditions within the region.

12. The method of claim 1, wherein sending the message to the off-board location comprises indicating to the off-board location that the EMS is not being used by the vehicle within the region because of a configuration issue with the EMS.

13. The method of claim 1, further comprising enabling an operator of the vehicle to select a reason why the EMS is not being used within the region, wherein sending the message to the off-board location comprises indicating to the off-board location that the EMS is not being used by the vehicle within the region because of the reason selected by the operator.

14. A method comprising:

receiving a message at an off-board location using a computer, the message indicating that an energy management system (EMS) associated with a vehicle traveling along a trip within a transportation network is not being used by the vehicle when the vehicle is within a region of the transportation network, wherein the EMS uses a trip plan of operational settings for the vehicle, and wherein the trip plan designates the operational settings for the vehicle in order to reduce at least one of fuel consumed or emissions generated during the trip relative to traveling according to another plan; and

tracking, at the off-board location, use of the EMS by the vehicle as the vehicle travels along the trip within the transportation network using the computer.

15. The method of claim 14, wherein the message received at the off-board location further indicates that the EMS is allowed to be used within the region.

16. The method of claim 14, wherein receiving the message at the off-board location comprises receiving the message from the vehicle.

17. The method of claim 14, wherein receiving the message comprises receiving at least one message for each of a plurality of trips of the vehicle.

18. The method of claim 14, wherein receiving the message comprises receiving at least one message for at least one trip of each of a plurality of vehicles.

19. The method of claim 14, wherein tracking the use of the EMS comprises tracking use of the EMS for a plurality of trips of the vehicle.

20. The method of claim 14, wherein tracking the use of the EMS comprises tracking use of the EMS for at least one trip of each of a plurality of vehicles.

21. The method of claim 14, further comprising evaluating an operator of the vehicle based on tracking of the use of the EMS.

22. The method of claim 14, further comprising allotting duties of vehicle operators based on tracking of the use of the EMS.

23. The method of claim 14, further comprising revising the trip plan of the vehicle based on tracking of the use of the EMS.

24. A system comprising:

an energy management system (EMS) associated with a vehicle that is configured to travel in a transportation network, the EMS being configured to use a trip plan of operational settings for the vehicle, wherein the trip plan designates the operational settings for the vehicle in order to reduce at least one of fuel consumed or emissions generated during the trip relative to traveling according to another plan; and

a control unit for the vehicle, the control unit being configured to control operation of the vehicle and being operatively connected to the EMS, wherein the control unit is configured to;

determine whether the EMS is available for use by the vehicle;

determine whether the EMS is being used by the vehicle; and

store information obtained from the determination of whether the EMS is being used by the vehicle.

25. The system of claim 24, wherein the control unit is configured to determine whether the EMS is available for use by the vehicle by determining whether the EMS is on-line.

26. The system of claim 24, wherein the control unit is configured to determine whether the EMS is being used by the vehicle by determining whether a trip plan of the EMS is being followed by the vehicle.

27. The system of claim 24, wherein the control unit is configured to determine whether the EMS is being used by the vehicle by determining whether an operator of the vehicle is following at least one control command within a predetermined threshold.

28. The system of claim 24, wherein the control unit is configured to store information by storing whether the EMS was available for use by the vehicle at at least one of at least one specific time or within at least one time period.
