Transforming map data for efficient vehicle range projection
First Claim
1. A system for determining a projected range of a vehicle, the system comprising:
- a storage element that stores map information regarding a geographic area, the map information comprising a plurality of links;
a processor that generates a set of range projection links based at least partly on the map information by evaluating the plurality of links to identify a plurality of paths extending radially outward in a plurality of directions from the vehicle; and
a display element comprising a graphics processing unit for (i) generating a monochrome bitmap based at least partly on the set of range projection links, (ii) rendering the set of range projection links within the monochrome bitmap, and (iii) tracing the rendered links to generate a polygon outline of the range of the vehicle.

Abstract
A system adapted to determine a projected range of a vehicle is described. The system includes: a storage element adapted to store a set of parameters associated with a vehicle; a map evaluation element adapted to retrieve information regarding a geographic area associated with a position of the vehicle; and a processing element adapted to determine the projected range of the vehicle based at least partly on the set of parameters and the retrieved information. An automated method of projecting a range of a vehicle includes: generating a set of range projection links; generating a monochrome bitmap based at least partly on the set of range projection links; rendering the set of range projection links within the monochrome bitmap; and tracing the rendered links to generate a polygon outline of the range of the vehicle. An automated method of caching map data for vehicle range projection is described.

8. An automated method, executed by one or more processors of a computer system, for projecting a range of a vehicle, the method comprising:
-
retrieving map information regarding a geographic area, the map information comprising a plurality of links; generating a set of range projection links based at least partly on the retrieved information by evaluating the set of links to identify a plurality of paths extending radially outward in a plurality of directions from the vehicle; generating a monochrome bitmap by a graphics processor based at least partly on the set of range projection links; rendering by the graphics processor the set of range projection links within the monochrome bitmap; and tracing the rendered links to generate a polygon outline of the range of the vehicle. - View Dependent Claims (9, 10, 11, 12, 13, 14)
