VEHICLE NAVIGATION SYSTEM PROVIDING TRAFFIC ADVISORIES BASED ON TRAFFIC INFORMATION AND LEARNED ROUTE
First Claim
1. A method of providing advisory information to a driver of a vehicle, the method comprising:
- determining a route empirically based on historical travel data of the vehicle;
receiving real-time traffic information;
referencing the real-time traffic information against the route; and
outputting a notification to the driver if a correspondence is found between the real-time traffic information and the route.

Abstract
An on-board automobile navigation system provides advisory information to the driver based on real-time traffic information and a learned commute route. The system empirically determines a commute route based on historical travel data of the vehicle. The system further receives real-time traffic information via a wireless link. The real-time traffic information may include information relating to traffic accidents, construction, and other traffic problems and the locations of such problems. At power up, the system automatically determines whether the present day and time are within a previously defined commute time window and, if so, prompts the driver to accept or decline a previously defined commute destination. The system automatically receives the real-time traffic information and compares the location information associated with any traffic problems to the commute route. If the system determines that the location of a traffic problem falls on or near the commute route, then the system outputs an appropriate notification to the user and, if possible, computes an alternative route.

7. In an on-board navigation system for assisting a driver of an automobile in navigating, a method of providing advisory information to the driver, the method comprising:
-
acquiring information on a travel history of the automobile;
identifying a commute route based on the information on the travel history of the automobile and a street map database;
in response to a power-up of the navigation system, receiving real-time traffic information from a remote source, the real-time traffic information including location information;
comparing the location information with the commute route; and
outputting a notification to the driver if the location information substantially matches a location on the commute route. - View Dependent Claims (8, 9, 10, 11, 12)

13. An on-board navigation system for assisting the driver of an automobile in navigating, the system comprising:
-
means for storing a street map database;
means for automatically learning a commute route based on historical travel data of the vehicle and the street map database;
means for receiving real-time traffic information including location information;
means for referencing the location information against the commute route in response to a power-up of the navigation system; and

18. A system for assisting a driver of an automobile in navigating, the system comprising:
-
a processor for controlling operation of the system;
an input subsystem coupled to the processor for receiving user inputs;
an output subsystem coupled to the processor for outputting guidance information;
a sensor subsystem coupled to the processor for measuring travel parameters of the automobile;
