Autonomous destination determination
First Claim
Patent Images
1. A method to autonomously determine a destination of a vehicle employing a GPS-based navigation system comprising:
- a one-time configuration process and a destination determination process, said one-time configuration process comprising;
(a) inputting one or more routes to be autonomously determined in said system, each route including a starting point and an end point, by entering said starting point and said end point in said GPS-based navigation system;
(b) displaying said route through a map with a series of decision points;
(c) manually selecting a subset of said decision points as close to the starting point as possible to identify a vehicle'"'"'s movement;
(d) ordering said subset of said decision points;
(e) storing said ordered subset and said end point as a pattern key for said route, said pattern key uniquely identify said route from said starting point to said end point;
(f) repeating (a)-(e) for inputting each route to be autonomously determined;
said destination determination process comprising;
(g) continuously comparing a vehicle'"'"'s current location with each ordered decision point of each pattern key based on said GPS-based navigation system;
(h) if said vehicle'"'"'s location matches with said decision points of one or more pattern keys, checking if said vehicle passed through all decision points of said pattern keys;
(i) if said vehicle passed through all decision points of a pattern key in said defined order, said end point of said pattern key is dynamically predicted as said vehicle'"'"'s destination; and
(j) returning to step (g).

Abstract
A method to autonomously determine a destination in navigation system is disclosed. The system is preconfigured with all the routes that a vehicle takes. The system constantly checks if the vehicle takes known routes. After finding out that the vehicle has been taken a known route, a final destination is determined.
