Method for providing information and system for providing information
First Claim
1. An information providing method for providing information to an occupant of a vehicle, the method comprising the steps of:
- detecting position information on the vehicle with information equipment installed in the vehicle;
accumulating, as a travel information history, routes of the vehicle obtained from the detected position information in the manner of transition among nodes;
predicting a destination of the vehicle by referring to a route along which the vehicle has traveled to the current time and to the accumulated travel information history, when detecting the occurrence of a given event; and
providing information regarding the predicted destination to the occupant via the information equipment,wherein in the predicting step, a destination of the vehicle is predicted by referring to transition among nodes accumulated as the travel information history and a series of nodes from a departure of the vehicle to a current position,wherein in the predicting step, a number of nodes is increased by using previous nodes starting from a current node in reverse chronological order, and a series of nodes with which an amount of data of transition among nodes accumulated as the travel information history exceeds a predetermined value are used to predict a destination of the vehicle.

Abstract
In a car navigation system (1), a position information detection means (11) detects position information on a vehicle using, for example, a GPS. A travel information history of the vehicle obtained based on the detected position information is accumulated in a travel information history means (15). When detecting an event such as start of an engine, an action prediction means (17) predicts a destination of the vehicle by referring to a route to the current time and to the accumulated travel information history. Commercial or traffic information regarding the predicted destination is acquired by an information acquisition means (18) from a server (2), and then is displayed on a screen, for example, by an information provision means (19).
