VEHICLE NAVIGATION SYSTEM |
摘要 |
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 ( &kgr;) is stored for the curvature attribute for corresponding links. The mean absolute curvature ( &kgr;) 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. |
