An energy management system and method for a vehicle system operate the vehicle system according to a current trip plan as the vehicle system travels along a route during a trip. The current trip plan designates operational settings of the vehicle system. The system and method also revise the current trip plan into a revised trip plan responsive to current, actual operation of the vehicle system differing from the current trip plan by at least a designated threshold amount. The revised trip plan designates operational settings of the vehicle system and includes an initial designated operational setting that matches the current, actual operation of the vehicle system.

1. A system comprising: a controller configured to generate one or more signals to control movement of a vehicle along a route according to a trip plan that designates operational settings of the vehicle as a function of a location on the route as the vehicle moves along the route, the controller configured to receive requests to modify the trip plan and to compare parameters of the requests to identify an optional request and a higher priority request, the controller also configured to one or more of revise the operational settings of the trip plan to include a change requested by each of the optional request and the higher priority request or revise the operational settings of the trip plan according to a change included in the higher priority request that has precedence over a change included in the optional request. 2. The system of claim 1, wherein the controller is configured to compare distances between a current location of the vehicle and a location where each of the requests deviate from the trip plan as the parameters of the requests. 3. The system of claim 1, wherein the controller is configured to compare times between a current time and a time at which each of the requests deviate from the trip plan as the parameters of the requests. 4. The system of claim 1, wherein the controller is configured to compare processing times of the controller in modifying the trip plan according to the requests as the parameters of the requests. 5. The system of claim 1, wherein the controller is configured to revise the operational settings of the trip plan to include a change requested by each of the optional request and the higher priority request. 6. The system of claim 1, wherein the controller is configured to revise the operational settings of the trip plan according to a change included in the higher priority request that has precedence over a change included in the optional request. 7. The system of claim 1, wherein the controller is configured to automatically generate the one or more signals to direct the vehicle to move along the route according to the trip plan. 8. The system of claim 1, wherein the controller is configured to determine priorities of the requests based on one or more of: which estimator module of several different estimator modules provided the requests,whether the requests are based on the parameters one or more other requests, orwhether the requests are based on sensor-provided information, operator feedback, or physics-based calculations. 9. A method comprising: controlling a vehicle to travel along a route according to a trip plan that designates operational settings of the vehicle as a function of a location on the route as the vehicle moves along the route;comparing parameters of requests to modify the trip plan that are received to identify an optional request and a higher priority request; andone or more of: revising the operational settings of the trip plan to include a change requested by each of the optional request and the higher priority request, orrevising the operational settings of the trip plan according to a change included in the higher priority request that has precedence over a change included in the optional request. 10. The method of claim 9, wherein the parameters of the requests that are compared include distances between a current location of the vehicle and a location where each of the requests deviate from the trip plan. 11. The method of claim 9, wherein the parameters of the requests that are compared include times between a current time and a time at which each of the requests deviate from the trip plan. 12. The method of claim 9, wherein the parameters of the requests that are compared include processing times of one or more processors involved in modifying the trip plan according to the requests. 13. The method of claim 9, wherein the method includes revising the operational settings of the trip plan to include a change requested by each of the optional request and the higher priority request. 14. The method of claim 9, wherein the method includes revising the operational settings of the trip plan according to a change included in the higher priority request that has precedence over a change included in the optional request. 15. The method of claim 9, wherein controlling the vehicle includes automatically generating a control signal to direct the vehicle to move along the route according to the trip plan. 16. The method of claim 9, further comprising determining priorities of the requests based on one or more of: which estimator module of several different estimator modules provided the requests,whether the requests are based on the parameters one or more other requests, orwhether the requests are based on sensor-provided information, operator feedback, or physics-based calculations. 17. The method of claim 9, wherein the method comprises both: revising the operational settings of the trip plan according to the change included in the higher priority request responsive to the higher priority request including the change that has precedence over the change included in the optional request; andrevising the operational settings of the trip plan to include the change requested by the optional request and the change requested by the higher priority request responsive to determining that an absolute limit on a number of permitted changes to the trip plan is not exceeded. 18. A system comprising: one or more processors configured to generate signals that control movement of a vehicle, the one or more processors generating the signals to direct the vehicle to travel along a route according to a trip plan that designates first operational settings to be implemented by the vehicle at one or more of different times, distances along the route, or locations along the route, the one or more processors configured to receive plural requests to revise the trip plan during movement of the vehicle along the route, the one or more processors configured to determine a hierarchical order of the requests based on a determined necessity of the requests, wherein the one or more processors are configured to revise the trip plan according to one or more of the requests based on the hierarchical order that is determined. 19. The system of claim 18, wherein the one or more processors are configured to revise the trip plan based on at least two of the requests that are not mutually exclusive of each other. 20. The system of claim 18, wherein the one or more processors are configured to revise the trip plan by changing one or more of the first operational settings designated by the trip plan such that an initial designated operational setting of the trip plan that is revised matches a current, actual operation of the vehicle. 21. The system of claim 20, wherein the current, actual operation of the vehicle differs from the trip plan during a time period that the initial designated operational setting of the revised trip plan is scheduled to be implemented by the vehicle. 22. The system of claim 18, wherein the one or more processors are configured to revise the trip plan by designating second operational settings to be implemented by the vehicle at one or more different times, locations along the route, or distances along the route, the second operational settings differing from the first operational settings, wherein the second operational settings include an initial designated operational setting that matches a current, actual operation of the vehicle at a time when the trip plan that is revised is implemented. 23. The system of claim 22, wherein the current, actual operation of the vehicle differs from the trip plan during a time period that the initial designated operational setting of the revised trip plan is scheduled to be implemented by the vehicle.
