Abstract

It is an object of the present invention to provide a driving support information generation device, a driving support information generation method, a driving support device, and a driving support method which make it possible to present effective caution information to drivers. The driving support information generation device of the present invention includes a processor to execute a program; and a memory to store the program which, when executed by the processor, performs processes of collecting vehicle information including traveling locus information indicating a traveling locus of at least one vehicle which travels a predetermined road section and generating cautionary information which is information to require a driver of the at least one vehicle to exercise caution when the at least one vehicle travels the section, on the basis of the collected vehicle information. The cautionary information is generated on the basis of variation in traveling of the vehicle.

Claims

1. A driving support information generation device comprising:

a processor to execute a program; and

a memory to store the program which, when executed by the processor, performs processes of,

collecting vehicle information including traveling locus information indicating a traveling locus of at least one vehicle which travels a predetermined road section; and

generating cautionary information which is information to require a driver of said at least one vehicle to exercise caution when said at least one vehicle travels said section, based on said collected vehicle information, wherein

said cautionary information is generated based on a variation in the traveling locus of said at least one vehicle.

2. The driving support information generation device according to claim 1, wherein said program further performs a process of generating a road condition of said section or a condition of said at least one vehicle as said cautionary information based on a plurality of pieces of said traveling locus information.

3. The driving support information generation device according to claim 1, wherein said program further performs a process of generating a driving skill of said at least one vehicle as said cautionary information based on a plurality of pieces of said traveling locus information.

4. The driving support information generation device according to claim 1, wherein

said at least one vehicle is one vehicle, and

said program further performs a process of collecting said vehicle information of said one vehicle which travels said section a plurality of times.

5. The driving support information generation device according to claim 4, wherein said program further performs a process of generating said cautionary information based on variation in said traveling locus of said one vehicle in said section.

6. The driving support information generation device according to claim 5, wherein said program further performs a process of generating said cautionary information based on a change with time of a degree of variation in said traveling locus.

7. The driving support information generation device according to claim 4, wherein

said vehicle information includes information on acceleration of said one vehicle, and

said program further performs a process of generating said cautionary information also based on variation in said acceleration of said one vehicle in said section.

8. The driving support information generation device according to claim 1, wherein

said at least one vehicle is a plurality of vehicles, and

said program further performs a process of collecting said vehicle information of each of said plurality of vehicles which travels said section a plurality of times.

9. The driving support information generation device according to claim 8, wherein said program further performs a process of generating said cautionary information based on variation in said traveling locus of said each of said plurality of vehicles in said section.

10. The driving support information generation device according to claim 9, wherein said program further performs a process of generating said cautionary information based on a change with time of a degree of variation in said traveling locus.

11. The driving support information generation device according to claim 10, wherein said program further performs a process of, in a case where said change with time of said degree of variation in said traveling locus of only one vehicle of said plurality of vehicles becomes larger, determining that said one vehicle has been deteriorated.

12. The driving support information generation device according to claim 10, wherein said program further performs a process of, in a case where said change with time of said degree of variation in said traveling locus of only one vehicle of said plurality of vehicles becomes smaller, determining that a driving skill of a driver of said one vehicle has been improved.

13. The driving support information generation device according to claim 10, wherein said program further performs a process of, in a case where said change with time of said degree of variation in said traveling locus of each of said plurality of vehicles becomes larger, determining that a road condition of said section has been deteriorated.

14. The driving support information generation device according to claim 10, wherein said program further performs a process of, in a case where said change with time of said degree of variation in said traveling locus of each of said plurality of vehicles becomes smaller, determining that a road condition of said section has been improved.

15. The driving support information generation device according to claim 8, wherein

said vehicle information includes information on acceleration of each of said plurality of vehicles, and

said program further performs a process of generating said cautionary information also based on variation in said acceleration of said each of said plurality of vehicles in said section.

16. The driving support information generation device according to claim 1, wherein

said vehicle information includes information on vehicle model of said at least one vehicle, and

said program further performs a process of collecting said vehicle information for each said vehicle model.

17. A driving support device comprising:

a processor to execute a program; and

a memory to store the program which, when executed by the processor, performs processes of,

acquiring said cautionary information from a driving support information generation device as defined in claim 1; and

making cautioning to said driver of said at least one vehicle based on said acquired cautionary information.

18. A driving support device comprising:

a processor to execute a program; and

a memory to store the program which, when executed by the processor, performs processes of,

acquiring said cautionary information from a driving support information generation device as defined in claim 1;

controlling a travel of said at least one vehicle; and

controlling said travel of said at least one vehicle based on said cautionary information.

19. A driving support information generation method comprising:

collecting vehicle information including traveling locus information indicating a traveling locus of at least one vehicle which travels a predetermined road section; and

generating cautionary information which is information to require a driver of said vehicle to exercise caution when said at least one vehicle travels said section, based on said vehicle information collected, wherein

said cautionary information is generated based on a variation in the traveling locus of said at least one vehicle.

20. A driving support method comprising:

acquiring said cautionary information generated by the driving support information generation method as defined in claim 19; and

making cautioning to said driver of said at least one vehicle based on said cautionary information acquired.
