Embodiment Construction

[0056] The following description is merely exemplary in nature and is not intended to limit the invention, its application or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0057] According to an exemplary embodiment of the present invention, the driving range of the vehicle is determined by considering the routing method and driving constraints. Different routing methods have different routing goals, eg, to minimize travel time, minimize travel distance, and / or minimize energy (eg, gasoline and / or electricity) usage. As used herein, the term "travel constraints" refers to vehicle range limitations such as, but not limited to: distance (eg, within three miles); amount of time (eg, within three minutes); or energy usage (eg, less than 0.3 kWh). According to an exemplary embodiment, information about the planned driving trip of the vehicle is output to a display device in the veh...

Abstract

Vehicle range projection is implemented by a host system having logic executable thereon. The logic identifies a starting location of a vehicle and identifies destination locations for the vehicle. The logic also builds routes from the starting location to the destination locations based on routing objectives and travel constraints. The logic further outputs at least a portion of at least one route and travel cost information associated with the at least a portion of at least one route.

Description

technical field [0001] The present invention relates to data processing, and more particularly to determining geographically reachable areas for vehicles based on routing goals and driving constraints. Background technique [0002] Global Positioning Systems (GPS), handheld devices, and online map routing services provide mechanisms to navigate from one point to another by calculating a route based on information derived from road maps. Routing systems typically have an availability feature that automatically calculates the type of direction expected. The usability feature allows the operator to specify routing goals such as: shortest distance (using an algorithm to determine the shortest distance from one point to the next); minimum amount of travel time (using an algorithm to determine the shortest distance based on highway speed limits and distances) , and calculate the resulting driving time); least highway use; least energy use (gasoline and / or electric); and least tol...
