FUEL EFFICIENT ROUTING SYSTEM AND METHOD
First Claim
1. A method of determining and displaying a more fuel efficient vehicle route between two locations from a plurality of possible different routes, the different routes being made up of links or route segments that begin and end with a node or link transition, each different route comprising at least one different link, the method comprising:
- (a) determining one or more energy values for links and nodes that define different routes between the two locations;
(b) storing the energy values associated with each link in association with the respective link and storing the energy values associated with each node in association with the respective node;
(c) summing the stored energy values associated with the links and nodes of plural different routes between the two locations to determine a total energy value for each of the plural different routes;
(d) selecting the route having the lowest total energy value; and
(e) displaying at least portions of the selected route to an operator of a vehicle, whereby the operator of the vehicle can follow the displayed route.

Abstract
A more fuel efficient route between two locations is determined from a plurality of possible different routes and displayed. The different routes can be made up of links or route segments that can begin and end with a node or link transition, each different route comprising at least one different link. In one specific example, a simulation is made utilizing map data, vehicle specific data including mass, traffic congestion and driver driving style characteristics to determine energy values which are stored in association with links and nodes. The stored energy values associated with the links and nodes of plural different routes are then combined, such as by summing, to determine a total energy value for each of the plural different routes. A route having a low energy value is then selected. At least a portion of the route can be displayed to an operator of a vehicle, whereby the operator of the vehicle can follow the displayed route.
