Abstract

A vehicle information processing system includes a database that mutually associates and stores driving operation information of a driver and position information of a vehicle for each candidate of an assistance area; and a specification unit that determines a vehicle stop based on the information stored in the database, and specifies an assistance area based on stop frequency in the same area. By this configuration, the assistance area can be specified by learning a driving action of the driver based on the database which stores information for each vehicle, and an assistance that is appropriate for the driver can be performed for each vehicle.

Claims

1-12. -12. (canceled)

13. A vehicle information processing system comprising:

a database that mutually associates and stores deceleration operation information indicating deceleration operation by a driver and position information of a vehicle; and

a specification unit that calculates a frequency of the deceleration operation in a same section based on the information stored in the database, and specifies a section where the frequency is equal to or more than a threshold value as an assistance area where an assistance regarding the deceleration operation is performed with respect to the driver.

14. The vehicle information processing system according to claim 13, wherein the assistance area includes a position where the deceleration operation is performed, and has a predetermined distance in a direction of the vehicle travel.

15. The vehicle information processing system according to claim 14, wherein the database stores an operation performed in order of accelerator-off, brake-on/off at least once, and accelerator-on, as the deceleration operation information.

16. The vehicle information processing system according to claim 13, wherein the assistance area candidate is set based on the position information predicted in advance of where the vehicle is likely to stop.

17. The vehicle information processing system according to claim 13, wherein the specification unit classifies an operation into an acceleration operation and a deceleration operation from an operation transition order using the driving operation information stored in the database.

18. The vehicle information processing system according to claim 17, wherein the driving operation information when the vehicle stops or the driving operation information when the vehicle starts is extracted based on the classified acceleration operation and deceleration operation, and an assistance is performed with respect to the driver using the extracted driving operation information.

19. The vehicle information processing system according to claim 13, wherein behavior information of the vehicle is associated and stored in addition to the deceleration operation information and the position information in the database.

20. The vehicle information processing system according to claim 13, wherein an assistance with respect to the vehicle driver is an operation assistance during deceleration stop and/or an operation assistance during a start acceleration.

21. The vehicle information processing system according to claim 13, wherein the deceleration operation counted in the frequency of the deceleration operation is the deceleration operation during the deceleration stop and/or the deceleration operation during the start acceleration from the stop by the deceleration operation.

22. The vehicle information processing system according to claim 13, wherein the database is included in a center which performs the assistance with respect to the vehicle.

23. The vehicle information processing system according to claim 13, wherein the database is included in the vehicle.

24. A driving assistance system comprising:

a database that mutually associates and stores deceleration operation information indicating deceleration operation by a driver and position information of a vehicle;

a specification unit that calculates a frequency of the deceleration operation in a same section based on the information stored in the database, and specifies a section wherein the frequency is equal to or more than a threshold value as an assistance area where an assistance regarding the deceleration operation is performed with respect to the driver; and

an assistance unit that performs the assistance regarding the deceleration operation with respect to the driver based on the assistance area specified by the specification unit.
