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. A vehicle information processing system comprising:

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

control circuitry 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 when the vehicle passes through the assistance area a subsequent time.

2. The vehicle information processing system according to claim 1, 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.

3. The vehicle information processing system according to claim 2, 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.

4. The vehicle information processing system according to claim 1, wherein the assistance area is set based on the position information predicted in advance of where the vehicle is likely to stop.

5. The vehicle information processing system according to claim 1, wherein the control circuitry 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.

6. The vehicle information processing system according to claim 5, 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.

7. The vehicle information processing system according to claim 1, wherein behavior information of the vehicle is associated and stored in addition to the deceleration operation information and the position information in the database.

8. The vehicle information processing system according to claim 1, 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.

9. The vehicle information processing system according to claim 8, wherein the deceleration operation counted in the frequency of the deceleration operation is same as the deceleration operation during the deceleration stop and/or the deceleration operation during the start acceleration.

10. The vehicle information processing system according to claim 1, wherein the database is included in a center which performs the assistance with respect to the vehicle.

11. The vehicle information processing system according to claim 1, wherein the database is included in the vehicle.

12. A driving assistance system comprising:

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

control circuitry 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 when the vehicle passes through the assistance area a subsequent time; and

control circuitry that implements the assistance regarding the deceleration operation with respect to the driver based on the assistance area specified by the control circuitry.
