Adaptive navigation system for estimating travel times
First Claim
Patent Images
1. A method of estimating travel time, comprising:
- obtaining an actual time taken by a vehicle for traveling a first route during a trip, wherein the actual time for traveling the first route during the trip is determined by a navigation system coupled to the vehicle during the trip;
updating a rolling average of travel time taken by the vehicle for traveling the first route based on the actual time taken during the trip;
determining at least one custom travel factor based on the rolling average of travel time taken by the vehicle for traveling the first route, the custom travel factor indicating a time adjustment for estimating travel times and is based on at least one of driving habits of a user associated with the vehicle, road conditions and traffic congestion; and
estimating a travel time for at least a second route using the custom travel factor.

Abstract
An estimated travel time for a route generated by a navigation system can be modified using a route-specific, custom travel factor computed from data collected by the navigation system while the user is traveling the route. In one aspect, the data can be stored in a local or remote database accessible by the navigation system. The data can be used to classify routes so that custom travel factors computed for a route in a given class can be used to estimate travel times for other routes in the same class. In another aspect, the classified custom travel factors can be shared with other users.

12. A navigation system, comprising:
-
a processor; and a computer-readable medium coupled to the processor and having instructions stored thereon, which, when executed by the processor, causes the processor to perform operations comprising; obtaining an actual time taken by a vehicle for traveling a first route during a trip, wherein the actual time for traveling the first route during the trip is determined by a navigation system coupled to the vehicle during the trip; updating a rolling average of travel time taken by the vehicle for traveling the first route based on the actual time taken during the trip; determining at least one custom travel factor based on the rolling average of travel time taken by the vehicle for traveling the first route, the custom travel factor indicating a time adjustment for estimating travel times and is based on at least one of driving habits of a user associated with the vehicle, road conditions and traffic congestion; and estimating a travel time for at least a second route using the custom travel factor. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
