Abstract

Official abstract text for this publication.

A vehicle navigation system having a database configured to store map data. The database includes links corresponding to road segments and attributes associated with the links. The map data includes at least some links associated with a curvature attribute. A mean absolute curvature is stored for the curvature attribute for corresponding links. The mean absolute curvature may be determined from a normalized sum or integral of absolute curvature values along the road segment corresponding to the link. The system includes a processing unit configured to estimate an energy consumption of the vehicle for a link using the curvature attribute retrieved from the database for the link.

First claim

Opening claim text (preview).

What is claimed is: 1. A vehicle navigation system, comprising: a database configured to store map data having links corresponding to road segments and attributes associated with the links, the map data having at least some links associated with a rolling resistance attribute and a grade resistance attribute, the rolling resistance attribute for a link having a rolling resistance attribute value (g cos ) proportional to a sum or an integral over the cosine of the angles of elevati…
