Off-board navigation system with personalized navigation database
First Claim
1. A method for guiding a user of an off-board vehicle navigation system along a recommended route, said method comprising the following steps:
- a.) requesting a route to a destination and requesting a desired category of points of interest from a remote unit;
b.) receiving said request from said step a.) at a supply location;
c.) calculating a recommended route to said destination in relation to said desired category of points of interest on a database of roads and a plurality of points of interest located at said supply location;
d.) filtering said database to provide a filtered map area including said recommended route and a point of interest within said desired category of points of interest; and
e.) transmitting said filtered map area to said 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.
