System and method for vehicle operation
First Claim
1. A system comprising:
- an energy management processing unit configured to be disposed onboard a vehicle system, the energy management processing unit comprising one or more processors configured to;
plan a trip profile specifying power settings for performing a mission based on trip data, the trip data including a plurality of parameters having expected values;
estimate respective experienced values of the plurality of parameters used by the trip planning module to plan the trip profile, determine respective differences between the experienced values and the expected values, and generate respective estimation re-plan requests of the trip profile when any of the differences exceed respective thresholds;
based on the estimation re-plan requests, select a re-plan request from among a first one of the estimation re-plan requests or an additional one or more of the estimation re-plan requests, prior to performing a re-plan of the trip profile, and provide the selected re-plan request to the trip planning module for re-planning the trip profile based on the selected re-plan request; and
control the vehicle system based on the re-planned trip profile.

Abstract
A system includes an energy management processing unit that includes a trip planning module, a plurality of estimator modules, and an arbiter module. The trip planning module plans a trip profile specifying power settings based on trip data including a plurality of parameters having expected values. Each of the estimator modules generates an estimation re-plan request when the difference between an expected and experienced respective trip planning parameter value exceeds a threshold. The arbiter module receives at least one estimation re-plan request from the plurality of estimator modules, determines whether a re-plan is to be performed based on at least one of a state of the vehicle system or additional estimation re-plan requests, and provides an arbitrated re-plan request to the trip planning module for re-planning the trip profile when it is determined that a re-plan is to be performed.

9. A method comprising:
-
obtaining, with one or more processors, a first estimation re-plan request for re-planning a trip profile, the first estimation re-plan request based on a difference between an expected value and an experienced value of a parameter used to generate the trip profile for a vehicle system; obtaining, with the one or more processors, one or more additional estimation re-plan requests based on a difference of one or more expected and experienced values of one or more respective additional parameters used to generate the trip profile; selecting, with the one or more processors, a re-plan request from among the first estimation re-plan request or the one or more additional estimation re-plan requests, prior to performing a re-plan of the trip profile; re-planning the trip profile based on the selected re-plan request; and controlling the vehicle system based on the re-planned trip profile. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A tangible and non-transitory computer readable medium comprising one or more computer software modules configured to direct one or more processors to:
-
obtain a first estimation re-plan request for a re-planning a trip profile, the first estimation re-plan request based on a difference between an expected value and an experienced value of a parameter used to generate the trip profile for a vehicle system; obtain, with the one or more processors, one or more additional estimation re-plan requests based on a difference of one or more expected and experienced values of one or more respective additional parameters used to generate the trip profile; select a re-plan request from among the first estimation re-plan request or the one or more additional estimation re-plan requests, prior to performing a re-plan of the trip profile; re-plan the trip profile based on the selected re-plan request; and control the vehicle system based on the re-planned trip profile. - View Dependent Claims (17, 18, 19, 20, 21)
