Car traffic information notification system, car traffic information notification method, and navigation system
First Claim
1. A traffic information notification system for use by a vehicle comprising:
- a controller that;
acquires vehicle travel history data;
automatically registers, on the basis of the acquired travel history data, at least one route along which the vehicle usually travels, a time at which the vehicle travels along each of the at least one routes, and traffic information associated with each of the at least one routes, the automatically registered traffic information comprising a location of historic traffic congestion and a degree of the historic traffic congestion;
compares current traffic information along a registered route to be traveled provided by a traffic information system with the automatically registered traffic information for that registered route to be traveled, the current traffic information comprising a location of current traffic congestion and a degree of the current traffic congestion; and
when the current traffic information is substantially different from the automatically registered traffic information, provides a notification of the substantially different current traffic information provided by the traffic information system.

Abstract
A traffic information notification system for use by a vehicle acquires vehicle travel history data, automatically registers, on the basis of the acquired travel history data, at least one route along which the vehicle usually travels, a time at which the vehicle travels along each of the at least one routes, and traffic information associated with each of the at least one routes. The traffic information system compares current traffic information along a registered route to be traveled provided by a traffic information system with the automatically registered traffic information for that registered route to be traveled, and provides a notification, when the current traffic information is substantially different from the automatically registered traffic information, of the substantially different current traffic information.

6. A traffic information notification system for use by a vehicle comprising:
-
a transmitter, disposed separately from the vehicle; a first controller, disposed on the vehicle, that; acquires vehicle travel history data; receives registered route data that is transmitted from the transmitter disposed separately from the vehicle, the registered route data including data indicating a time at which the vehicle travels along the route, and usual traffic information on the route, the usual traffic information comprising a location of usual traffic congestion and a degree of the usual traffic congestion; and when current traffic information provided by a traffic information system is substantially different from the usual traffic information, provides a notification of the substantially different traffic information together with data indicating a point on the registered route at which an unusual traffic condition indicated by the substantially different traffic information occurs, the current traffic information comprising a location of current traffic congestion and a degree of the current traffic congestion; and a second controller, disposed separately from the vehicle, that receives the travel history data, the travel history data being sequentially transmitted from the first controller. - View Dependent Claims (7, 8, 9, 10, 11)

12. A method for providing traffic notification, comprising:
-
acquiring vehicle travel history data; automatically registering, on the basis of the acquired travel history data, at least one route along which the vehicle usually travels, a time at which the vehicle travels along each of the at least one routes, and traffic information associated with each of the at least one routes, the automatically registered traffic information comprising a location of historic traffic congestion and a degree of the historic traffic congestion; comparing current traffic information along a registered route to he traveled provided by a traffic information system with the automatically registered traffic information for that registered route to be traveled, the current traffic information comprising a location of current traffic congestion and a degree of the current traffic congestion; and when the current traffic information is substantially different from the automatically registered traffic information, providing a notification of the substantially different current traffic information provided by the traffic information system. - View Dependent Claims (13, 14, 15)

16. A storage medium storing a set of program instructions executable on a data processing device and usable for providing traffic notification, the set of program instructions comprising:
-
instructions for acquiring vehicle travel history data; instructions for automatically registering, on the basis of the acquired travel history data, at least one route along which the vehicle usually travels, a time at which the vehicle travels along each of the at least one routes, and traffic information associated with each of the at least one routes, the automatically registered traffic information comprising a location of historic traffic congestion and a degree of the historic traffic congestion; instructions for comparing current traffic information along a registered route to be traveled provided by a traffic information system with the automatically registered traffic information for that registered route to be traveled, the current traffic information comprising a location of current traffic congestion and a degree of the current traffic congestion; and instructions for providing a notification, when the current traffic information is substantially different from the automatically registered traffic information, of the substantially different current traffic information provided by the traffic information system.
