Off-board navigation system with personalized navigation database
First Claim
1. A method for providing information to a remote unit for guiding a user of an off-board vehicle navigation system along a recommended route, the method comprising:
- receiving, at a supply location prior to any calculation of the route, a request from a remote unit for a route to a destination and a desired category representing a plurality of closely related points of interest;
calculating a recommended route to the destination in relation to the desired category on a database of roads and categories located at the supply location;
filtering the database to provide a filtered map area including the recommended route and a point of interest among the plurality of closely related points of interest;
receiving, at the supply location, information from the remote unit defining a width substantially perpendicular to the recommended route or a perimeter around each of a plurality of nodes along the recommended route;
determining, at the supply location, sizing of the filtered map area in response to the width or perimeter information; and
transmitting the filtered map area to the remote unit.

Abstract
An off-board navigation system includes a remote unit and a supply location. In operation, a navigation system user requests a desired route to a destination. Capability information relating to the user'"'"'s CPU and storage device capacities are also preferably provided to the supply location. Using the extensive database available at the supply location, the supply location calculates a recommended route to the desired destination in relation to the desired POIs. If the estimated size of the requested route meets the capabilities of the remote unit the supply location creates a filter using the requested parameters and applied to the extensive database at the supply location. In one embodiment, the filtered map area includes a width vector W defined substantially perpendicular to the recommended route R. In another embodiment, the filtered map area is defined in relation to a plurality of nodes N along the recommended route R. A perimeter P is defined around each node N along the recommended route R. Moreover, the type of road can be adjusted to meet the capability information relating to the user'"'"'s CPU and storage device.
