Abstract
Official abstract text for this publication.
A navigation system and related operating methods are provided for instructing an operator of a vehicle. The navigation system obtains a destination location and generates a proposed route to the destination location. The proposed route is defined by one or more driver decision points and associated driving maneuvers. Before the vehicle reaches an approaching driver decision point, the navigation system pre-calculates alternate routes between the approaching driver decision point and the destination location, and saves the alternate routes for subsequent activation. Pre-calculated alternate routes can also be used to determine and indicate the relative importance of an approaching driving maneuver. The driver can consider the importance of driving maneuvers when deciding whether or not to follow the recommended route.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer implemented navigation method for instructing an operator of a vehicle, the method comprising: obtaining, at a computer system having a processor, a destination location; generating, with the processor, a proposed route to the destination location, the proposed route defined by one or more driver decision points and associated driving maneuvers; and before the vehicle reaches an approaching driver decision point of the driver decision points,…
