Distributed energy management system and method for a vehicle system
First Claim
1. A method comprising:
- determining, using a first energy management system disposed onboard a first vehicle of a vehicle system, a first trip plan for a trip of the vehicle system from a first location to a second location over a first route that includes a first intersection with a second route, the first trip plan designating operational settings of the vehicle system for one or more of different times or different locations ahead of the vehicle system along the first route;
determining, using a second energy management system disposed onboard a second vehicle of the vehicle system, an alternate trip plan for the vehicle system, the alternate trip plan designating operational settings of the vehicle system for one or more of different times or different locations ahead of the vehicle system along the second route from the first intersection between the first route and the second route to the second location of the trip of the vehicle system, wherein the first trip plan and the alternate trip plan are determined prior to the vehicle system reaching the first intersection;
controlling movement of the vehicle system using a control unit, the movement of the vehicle system controlled by the control unit according to the first trip plan prior to the vehicle system reaching the first intersection;
switching, using the control unit, to controlling the movement of the vehicle system according to the alternate trip plan responsive to the vehicle system deviating from the first trip plan by traveling onto the second route from the first route through the first intersection;
responsive to the vehicle system deviating from the first trip plan by moving from the first route to the second route at the first intersection, determining one or more additional intersections disposed along the second route and one or more additional routes that diverge from the second route at the one or more additional intersections; and
determining one or more additional alternate trip plans associated with travel of the vehicle system along the respective one or more additional routes.

Abstract
A system and method for generating a trip plan for a vehicle system determine a first trip plan for a trip of a vehicle system from a first location to a second location over a first route that includes a first intersection with a second route. The first trip plan designates operational settings of the vehicle system. An alternate trip plan that extends along the second route from the first intersection to the second location of the trip of the vehicle system also is determined. The first and alternate trip plans are determined prior to the vehicle system reaching the first intersection. Movement of the vehicle system is controlled according to the first trip plan prior to the vehicle system reaching the first intersection and then controlled according to the alternate trip plan responsive to the vehicle system deviating from the first trip plan.
