Vehicle navigation system and method
First Claim
1. A computer-implemented method comprising:
- using a first computing system, dividing a route into a plurality of portions, each having a number of exits;
assigning a distance tolerance to each portion based at least in part on the number of exits, wherein a finite number of tolerances may be assigned, and wherein a highest tolerance corresponds to a fewest number of exits, a lower tolerance corresponds to a highest number of exits, and any remaining tolerances correspond to numbers of exists such that as numbers of exits increase, the tolerances decrease;
determining points defining the route such that the roads comprising the route fall within a bounded area defined by the tolerance in conjunction with a plurality of lines connecting successive points along the route; and
delivering the determined points to a vehicle computing system for navigating the vehicle toward a destination.

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.
