Abstract

An information processing device according to an embodiment includes a storage device and one or more processors configured to function as a setting unit and a record control unit. The setting unit sets a record level of history information according to a reliability of derivative information derived from output information of a sensor. The record control unit performs control to store the history information in the storage device according to the record level.

Claims

1. An information processing device comprising:

a storage device; and

one or more processors configured to function as a setting unit and a record control unit,

wherein

the setting unit sets a record level of history information according to a reliability of derivative information derived from output information of one or more sensors, and

the record control unit performs control to store the history information in the storage device according to the record level.

2. The information processing device according to claim 1, wherein

the derivative information includes at least one of sensor abnormality information indicating an abnormality of the sensor, contradiction information indicating contradiction of the output information of the sensors, driver state information indicating a state of a driver of a moving object, travel-planned route information, travel difficulty information, recommended lane information, peripheral situation analysis result information, and a driving amount of the moving object.

3. The information processing device according to claim 1, wherein

the setting unit sets the record level to be higher as the reliability is lower.

4. The information processing device according to claim 1, wherein the record level indicates an amount of data to be recorded per unit time.

5. The information processing device according to claim 1, wherein the record level is represented by at least one of record object information indicating whether or not information is an object to be recorded, record detail level, a record interval, and a storage period.

6. The information processing device according to claim 1, wherein

the one or more processors is further configured to function as a calculation unit, and

the calculation unit calculates the reliability depending on the derivative information.

7. The information processing device according to claim 6, wherein

the calculation unit calculates the reliability to be low as the derivative information is information indicating a state causing trouble in automatic traveling of the moving object.

8. The information processing device according to claim 7, wherein the state causing trouble in automatic traveling is at least one of a state where an obstacle is present within a range in which a distance from the moving object is equal to or shorter than a threshold and a state where an obstacle is present within a range equal to or shorter than a threshold of a route on which the moving object automatically travels.

9. The information processing device according to claim 6 wherein

the calculation unit calculates the reliability to be low as the derivative information is information indicating an abnormal state.

10. The information processing device according to claim 9, wherein the information indicating the abnormal state is at least one of sensor abnormality information in which the derivative information indicates an abnormality of the sensor and driver state information indicating a state where it is difficult for the driver to drive.

11. The information processing device according to claim 6, wherein the calculation unit calculates the reliability depending on the derivative information and a driving mode of the moving object.

12. The information processing device according to claim 1, wherein

the setting unit sets the record level according to the reliability of item derivative information for each piece of the item derivative information with respect to the derivative information including the item derivative information corresponding to each of a plurality of items.

13. The information processing device according to claim 1, wherein the history information includes at least one of the derivative information and the output information.

16. A moving object comprising:

the information processing device according to claim 1, and the one or more sensors.

14. An information processing method comprising:

setting a record level of history information according to a reliability of derivative information derived from output information of a sensor.

15. A computer program product comprising a non-transitory computer program for causing a computer to execute:

setting a record level of history information according to a reliability of derivative information derived from output information of a sensor.
