Abstract
The information processing device includes: an acquiring unit that acquires vehicle information including an acceleration of a vehicle and a detection time at which the acceleration is detected; a deriving unit that derives an amount of change of the acceleration per unit time using the vehicle information; a setting unit that sets a threshold value of the amount of change corresponding to an interval at which the acceleration is detected using the detection time; and an extracting unit that extracts the vehicle information corresponding to the amount of change as target data when the amount of change is equal to or larger than the threshold value.
Claims8
An information processing device comprising:
- a computer configured to:
- acquire, offboard via wireless communication, vehicle information including acceleration of a vehicle, and a detection time at which the acceleration is detected;
- derive an amount of change of the acceleration per unit time using the vehicle information;
- set a threshold value of the amount of change of the acceleration per unit time in accordance with an interval of detection of the acceleration using the detection time;
- extract the vehicle information corresponding to the amount of change of the acceleration per unit time as target data when the amount of change of the acceleration per unit time is equal to or larger than the threshold value;
- and
- control the computer to reduce an amount of data of the vehicle information and suppress an omission of the vehicle information based on the extracted vehicle information indicating whether a collision has occurred.
