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.

Energy management system and method for vehicle systems

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.
