1. An electric or hybrid-electric vehicle comprising a computer programmed to:
- identify a current location of a vehicle;
access a map within a database and identify a plurality of links therein;
pre-screen the plurality of links to identify if any of the plurality of links is within a given bounds of the current location; and
if one or more possible links are identified, then;
calculate a distance from the current location to one identified link of the one or more possible links;
if the calculated distance, and a plurality of previously identified current locations, are within a given distance to the one identified link, then forgo calculating the distance to the one identified link when determining a subsequent current location; and
upload power data for the vehicle corresponding to the subsequently determined current location into the database, the uploaded power data corresponding to the one identified link.

Abstract
A system for operating an electric or hybrid-electric vehicle includes a computer programmed to identify a location of a vehicle, access a map and identify a plurality of links therein, pre-screen the plurality of links to identify if any of the plurality of links is within a given bounds of the current location, and if one or more possible links are identified, then match the current location of the vehicle to one of the identified links, and upload power data for the vehicle corresponding to the matched location into a database.

1. An electric or hybrid-electric vehicle comprising a computer programmed to:
-
identify a current location of a vehicle; access a map within a database and identify a plurality of links therein; pre-screen the plurality of links to identify if any of the plurality of links is within a given bounds of the current location; and if one or more possible links are identified, then; calculate a distance from the current location to one identified link of the one or more possible links; if the calculated distance, and a plurality of previously identified current locations, are within a given distance to the one identified link, then forgo calculating the distance to the one identified link when determining a subsequent current location; and upload power data for the vehicle corresponding to the subsequently determined current location into the database, the uploaded power data corresponding to the one identified link. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A method of energy management of an electric or hybrid-electric vehicle comprising:
-
identifying a current location of a vehicle; applying a pre-screening algorithm with respect to a link within a map and the current location, the pre-screening algorithm based on a maximum link length of a historical power-use database; determining if one or more links are within a given bounds, and, if so, then; matching the current location of the vehicle to the link within the map via a subsequential matching algorithm; and uploading power information used by the vehicle along the link and at the current location into the historical power-use database. - View Dependent Claims (10, 11, 12, 13)

14. A computer readable storage medium having a computer program stored thereon and representing a set of instructions that when executed by a computer causes the computer to:
-
measure a current location of a vehicle; execute a pre-screening algorithm to determine possible links of a map that are within a predetermined distance from the current location; and
;if one or more links are within the predetermined distance from the current location, then the computer is caused to; execute a map-matching algorithm to determine which of the one or more links corresponds to the actual link along which the vehicle is traveling; and upload power information related to the vehicle at the current location to a historical database; if no link is within the predetermined distance from the current location, the instructions cause the computer to determine that the current location of the vehicle is off-road, and if K consecutive current locations are determined to be off-road, then the instructions cause the computer to assume that a next M subsequent current locations are off-road, wherein K and M are each integers greater than 1. - View Dependent Claims (15, 16, 17, 18, 19, 20)
