Vehicle Navigation System and Method
First Claim
1. A computer-implemented vehicle navigation method comprising:
- determining a vehicle route to a destination;
determining a type or speed of a wireless connection between a navigation server and a vehicle;
,assigning a tolerance in accordance with the connection type, the tolerance usable to determine if a vehicle is off-route, wherein the tolerance is increased or decreased inversely corresponding to the type or speed of the connection type;
using the assigned tolerance, determining points defining the route such that the roads comprising the route are within a bounded area defined by the tolerance; and
delivering the determined points to a vehicle computing system over the wireless connection.

Abstract
An efficient route-defining method includes determining a route to a destination. The exemplary method also includes determining a wireless device to server connection type and assigning a tolerance in accordance with a connection type. The tolerance is usable to determine if a vehicle is off-route, and the tolerance is increased or decreased inversely corresponding to the speed of the connection type. According to the illustrative method, the assigned tolerance is used to determine points defining the route, such that the roads comprising the route are within a bounded area. The bounded area may be defined by the tolerance in conjunction with a plurality of lines connecting successive points along the route. Finally, the method includes delivering the determined points to a vehicle computing system in communication with the server.
