Abstract

A route searching method using a route searching device for searching for a first route to reach a destination includes accumulating a history of activities of a driver in a database, when the history of activities is accumulated, setting a region based on a position on a map at which the history of activities is accumulated as a first region, increasing an area of the first region as the history of activities increases, and searching for a secondary route for reaching the destination from the first region using the route searching device.

First claim

The invention claimed is:

1. A route searching device comprising:
a setting unit configured to set a departure point and a destination of a vehicle;
an activity history acquisition unit configured to acquire a history of activities of a user of the vehicle;
a route searching unit configured to search for a driving route of the vehicle based on the departure point, the destination, and the history of activities; and
a route output unit configured to output the searched driving route,
wherein the route searching unit sets a predetermined region on a map in which the history of activities is accumulated as a first region and sets, as a second region, a region including the first region and further enlarged on a periphery of the first region based on the history of activities in the first region, so as to search for the driving route at least a part of which is in the second region excluding the first region.

2. The route searching device according to claim 1 , wherein the history of activities is acquired from a mobile terminal belonging to the user and a navigation system mounted in the vehicle.

3. The route searching device according to claim 1 , wherein the history of activities includes a driving history of the vehicle, and a staying history and a moving history of the user.

4. The route searching device according to claim 3 ,
wherein the driving history includes a frequency of use of an individual link composing a road system, and
wherein the staying history includes a staying time and a range of activities around a facility with a higher frequency of use at the destination or a point of transfer.

5. The route searching device according to claim 1 , wherein the route output unit outputs an estimated value of a required time for each of the first route and the secondary route, and a recommended order determined between the first route and the secondary route.

6. The route searching device according to claim 1 , wherein the second region is determined by reference to the history of activities conforming to a current time.

7. The route searching device according to claim 1 , wherein the second region is set such that an area of the second region increases as a degree or frequency of the history of activities increases.

8. A driving route searching method using a route searching device for searching for a driving route of a vehicle, the method comprising:
setting a departure point and a destination of the vehicle;
acquiring a history of activities of a user of the vehicle;
when searching for the driving route based on the departure point, the destination, and the history of activities, setting a predetermined region on a map in which the history of activities is accumulated as a first region, and setting, as a second region, a region including the first region and further enlarged on a periphery of the first region based on the history of activities in the first region, so as to search for the driving route at least a part of which is in the second region excluding the first region.

9. The route searching device according to claim 1 , wherein an electronic circuit comprises the route searching unit and the route output unit.

10. The route searching device according to claim 1 , wherein the setting unit comprises a touch panel.

11. The route searching device according to claim 1 , wherein the activity history acquisition unit comprises a mobile terminal belonging to the user.

12. The route searching device according to claim 1 , wherein the activity history acquisition unit comprises a navigation system mounted in the vehicle.

13. The route searching device according to claim 1 , wherein the route searching unit searches for a first route passing through the first region and a secondary route which is not in the first region but in the second region, and the searched driving route includes the first and the secondary routes.
