Abstract

A driving information recording apparatus that records driving information of a vehicle, the apparatus includes: a processor that: (i) associates, as a data file, information related to a driving condition of the vehicle with a driving mode of the vehicle at a time at which the driving condition occurred, and (ii) records the data file in a recording medium having a recording area. Thus, it is possible to provide a preferred technology for recording the driving information of the vehicle that has a switching function of driving modes.

Claims

1. A driving information recording apparatus that records driving information of a vehicle, the apparatus comprising:

a processor that;

(i) associates, as a data file, information related to a driving condition of the vehicle with a driving mode of the vehicle at a time at which the driving condition occurred, and (ii) records the data file in a recording medium having a recording area.

2. The driving information recording apparatus according to claim 1, wherein

the information related to the driving condition of the vehicle includes image information captured by a camera that is mounted on the vehicle.

3. The driving information recording apparatus according to claim 2, wherein

the processor records the data file in the recording medium only in a case where the driving mode of the data file is a specific driving mode.

4. The driving information recording apparatus according to claim 1, wherein

the processor selects a previously-recorded data file recorded in the recording area to be overwritten by a newly-created data file based on the driving mode of the previously-recorded data file in a case where a capacity of the recording medium has become full.

5. The driving information recording apparatus according to claim 1, wherein

in a case where a capacity of the recording medium has become full, the processor excludes a previously-recorded data file recorded in the recording area from being overwritten by a newly-created data file when the previously-recorded data file was recorded immediately before or immediately after switching occurred between the driving modes.

6. The driving information recording apparatus according to claim 1, wherein

the information related to the driving condition of the vehicle includes location information of the vehicle, and

in a case where a capacity of the recording medium has become full, the processor excludes a previously-recorded data file recorded in the recording area from being overwritten by a newly-created data file when the previously-recorded data file was recorded immediately before or immediately after the vehicle entered a place in which the driving mode should be switched.

7. The driving information recording apparatus according to claim 1, wherein

the driving mode is either (a) an autonomous driving mode in which at least any one of a driving operation, a braking operation and a steering operation of the vehicle is automatically performed, regardless of an operation by a driver, or (b) a non-autonomous driving mode.

8. A display system that displays driving information, the display system comprising:

a driving information recording apparatus that records driving information of a vehicle, the apparatus having a processor that;

(i) associates, as a data file, information related to a driving condition of the vehicle with a driving mode of the vehicle at a time at which the driving condition occurred, and (ii) records the data file in a recording medium; and

a display processing apparatus that displays the information recorded in the recording medium on a display apparatus.

9. The display system according to claim 8, wherein

the information related to the driving condition of the vehicle includes image information captured by a camera that is mounted on the vehicle, and

the display processing apparatus displays the driving mode and the image information that is temporally associated with the image information.

10. The display system according to claim 8, wherein

the display processing apparatus associates the driving mode with a route history of the vehicle and displays the driving mode on a map that indicates the route history.

11. The display system according to claim 8, wherein

the driving mode is either (a) an autonomous driving mode in which at least any one of a driving operation, a braking operation and a steering operation of the vehicle is automatically performed, regardless of an operation by a driver, or (b) a non-autonomous driving mode.

12. The display system according to claim 9, wherein

in a case where a location specification of a specified location is performed on a display screen that displays a map on which the driving mode associated with a route history of the vehicle is displayed, the display processing apparatus displays the image information corresponding to the specified location.

13. The display system according to claim 9, wherein

the processor records the data file in the recording medium, only in a case where the driving mode of the data file is a specific driving mode.

14. A recording method of recording driving information of a vehicle, the method comprising the steps of:

(a) acquiring information related to a driving condition of the vehicle;

(b) associating, as a data file, the information related to the driving condition of the vehicle with a driving mode at a time at which the driving condition occurred; and

(c) recording the data file in a recording medium having a recording area.

15. The recording method according to claim 14, wherein

the information related to the driving condition includes image information captured by a camera that is mounted on the vehicle.

16. The recording method according to claim 15, wherein

the step (c) records the data file in the recording medium only in a case where the driving mode of the data file is a specific driving mode.

17. The recording method according to claim 14, wherein

the step (c) selects a previously-recorded data file recorded in the recording area to be overwritten by a newly-created data file based on the driving mode of the previously-recorded data file in a case where a capacity of the recording medium has become full.

18. The recording method according to claim 14, wherein

in a case where a capacity of the recording medium has become full, the step (c) excludes a previously-recorded data file in the recording area from being overwritten by a newly-created data file when the previously-recorded data file was recorded immediately before or immediately after switching occurred between the driving modes.

19. The recording method according to claim 14, wherein

the information related to the driving condition of the vehicle includes location information of the vehicle, and

in a case where a capacity of the recording medium has become full, the step (c) excludes a previously-recorded data file in the recording area from being overwritten by a newly-created data file when the previously-recorded data file was recorded immediately before or immediately after the vehicle entered a place in which the driving mode should be switched.

20. The recording method according to claim 14, wherein

the driving mode is either (1) an autonomous driving mode in which at least any one of a driving operation, a braking operation and a steering operation of the vehicle is automatically performed, regardless of an operation by a driver, or (2) a non-autonomous driving mode.
