Hybrid energy power management system and method
First Claim
1. An energy management system for use with one of a plurality of hybrid vehicles, each vehicle having an engine and power converter providing primary electric power, a traction bus coupled to the power converter for carrying the primary electric power, a traction motor connected to the traction bus, said traction motor having a motoring mode being responsive to the primary electric power for propelling said one of a plurality of vehicles on said one of a plurality of routes, said traction motor having a dynamic braking mode generating dynamic braking electrical energy on the traction bus, the energy management system comprising:
- a device for providing one of position information and time information of said one of a plurality of vehicles at one of respective incremental positions and incremental times along said one of a plurality of routes;
a database for storing historical data of at least one of traction and auxiliary energy demand for each of the plurality of vehicles at each of said one of incremental positions and incremental times along each of the plurality of routes; and
an energy management processor coupled to said position identification device and said database for retrieving said historical data of each of said plurality of vehicles for each of said one of incremental positions and incremental times along said one of a plurality of routes to estimate at least one anticipated traction and auxiliary energy demand of said one of a plurality of vehicles at each of said incremental positions along said one of a plurality of routes.

Abstract
An energy management system is provided for use with one of a plurality of hybrid energy diesel electric vehicles. The energy management system includes a position identification device to provide position information of one the plurality of vehicles at incremental positions along one of a plurality of routes. More particularly, the energy management system includes a database to store historical data of a traction and/or auxiliary energy demand for each vehicle at incremental positions along each route, and an energy management processor coupled to the position identification device and the database. The energy management system retrieves historical data of each vehicle at incremental positions along each route to estimate an anticipated traction and/or auxiliary energy demand of the one of a plurality of vehicle at each incremental position along one of a plurality of routes.
