Abstract

A method for determining a mission plan for a powered system having at least one primary power generating unit when a desired parameter of the mission plan unobtainable and/or exceeds a predefined limit, the method includes identifying a desired parameter prior to creating a mission plan which may be unobtainable and/or in violation of a predefined limit, and notifying an operator of the powered system and/or a remote monitoring facility of the desired parameter.

Claims

1. A method for determining a mission plan for a powered system having at least one primary power generating unit when a desired parameter of the mission plan is at least one of unobtainable and exceeds a predefined limit, the method comprising:

identify a desired parameter prior to creating a mission plan which is at least one of unobtainable by a powered system or which is in violation of a predefined limit, the mission plan created for the powered system having at least one power generating unit, wherein the desired parameter comprises at least one of a throttle limit, a brake rate limit, a start speed for at least one of a mission and a segment of the mission, an end speed for at least one of the mission and the segment of the mission, an operation time for at least one of the mission and the segment of the mission, a desired speed setting at a defined point in the mission, a start notch setting for at least one of the mission and the segment of the mission, an end notch setting for at least one of the mission and the segment of the mission, or application of dynamic braking;

notifying , via a display, at least one of an operator of the powered system or a remote monitoring facility of the desired parameter being at least one of unobtainable or in violation of the predefined limit;

determining whether the predefined limit is at least one of a first limit or a second limit, the first limit being a limit for which an obtainable parameter that is proximate to the desired parameter can be used by the powered system without exceeding the first limit, the second limit being a limit that can be temporarily exceeded by the powered system; and

determining at least one of a time period or a condition to temporarily exceed the predefined limit when the predefined limit is the second limit.

2. The method according to claim 1, further comprising determining whether to at least one of exceed the predefined limit or identify an obtainable parameter proximate the desired parameter for inclusion in the mission plan.

3. The method according to claim 2, wherein the at least one of the operator or the remote monitoring facility are notified about whether to at least one of exceed the predefined limit or identify an obtainable parameter proximate the desired parameter.

4. The method according to claim 1, further comprising creating the mission plan.

5. The method according to claim 4, further comprising implementing the mission plan created where at least one of the predefined limit is exceeded or the obtainable parameter proximate the desired parameter is used.

6. The method according to claim 1, further comprising allowing the at least one of the operator or the remote monitoring facility to at least one of remove the predefined limit so that the mission plan is feasible or modify at least one other parameter to make the mission plan feasible.

7. The method according to claim 1, wherein notifying further comprises advising at least one of the operator or remote monitoring facility that exceeding the predefined limit is inevitable in a designated region of a mission.

8. The method according to claim 1, wherein notifying further comprises advising at least one of the operator or the remote monitoring facility of at least one parameter to modify in order to produce the mission plan.

9. The method according to claim 1, further comprising determining whether to modify the mission plan by at least one of exceeding the predefined limit or identifying an obtainable parameter proximate the desired parameter for inclusion in the mission plan that is modified so that the mission plan that is modified can be accomplished proximate to an intended objective of the mission plan prior to modifying the mission plan.

10. The method according to claim 1, further comprising revising the mission plan to direct the powered system to temporarily exceed the predefined limit when the predefined limit is the second limit.

11. The method according to claim 1, further comprising determining the obtainable parameter that is proximate to the desired parameter without exceeding the first limit when the predefined limit is the first limit.

12. The method according to claim 1, wherein the desired parameter comprises at least one character associated with at least one of the powered system or a parameter associated with a mission being performed by the mission plan.

13. A tangible and non-transitory computer readable medium comprising one or more modules configured to direct one or more processors to:

identify a desired parameter prior to creating a mission plan which is at least one of unobtainable by a powered system or which is in violation of a predefined limit, the mission plan created for the powered system having at least one power generating unit, wherein the desired parameter comprises at least one of a throttle limit, a brake rate limit, a start speed for at least one of a mission and a segment of the mission, an end speed for at least one of the mission and the segment of the mission, an operation time for at least one of the mission and the segment of the mission, a desired speed setting at a defined point in the mission, a start notch setting for at least one of the mission and the segment of the mission, an end notch setting for at least one of the mission and the segment of the mission, or application of dynamic braking; and

alert ,via a display, at least one of an operator or a remote monitoring facility that the desired parameter is at least one of unobtainable by the powered system or exceeds a predefined limit , wherein the one or more modules are configured to direct the one or more processors to determine at least one of a time period or a condition to temporarily exceed the predefined limit when the predefined limit is the second limit, wherein the one or more modules are configured to direct the one or more processors to direct the powered system to temporarily exceed the predefined limit when the predefined limit is the second limit.

14. The tangible and non-transitory computer readable medium of claim 13, wherein the one or more modules are configured to direct the one or more processors to determine whether the predefined limit is at least one of a first limit or a second limit, the first limit being a limit for which an obtainable parameter of the powered system that is proximate to the desired parameter can be used by the powered system without exceeding the first limit, the second limit being a limit that can be temporarily exceeded by the powered system.

15. The tangible and non-transitory computer readable medium of claim 13, wherein the one or more modules are configured to direct the one or more processors to determine the obtainable parameter that is proximate to the desired parameter without exceeding the first limit when the predefined limit is the first limit.

16. The tangible and non-transitory computer readable medium of claim 13, wherein the one or more modules are configured to direct the one or more processors to receive a feedback command from at least one of the operator or the remote monitoring facility and revise the mission plan based on the feedback command.
