IN-VEHICLE DATA RECORDING SYSTEM AND IN-VEHICLE DATA RECORDING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an in-vehicle data recording system more flexibly switching a plurality of recording modes of which the sorts of data to be recorded and sampling rates are different from each other.

SOLUTION: The in-vehicle data recording system 100 having both of a first mode for continuously recording data output from an in-vehicle apparatus 2 of a first group at a first sampling rate and a second mode for recording data output from an in-vehicle apparatus 3 of a second group at a second sampling rate higher than the first sampling rate for a predetermined period when a prescribed state is detected includes: a data abnormality generation mechanism analysis means 13 for analyzing a mechanism for generating data abnormality based on the data recorded in the first mode; and a recording mode switching means 12 for switching the first mode to the second mode before the generation of data abnormality based on an analysis result of the data abnormality generation mechanism analysis means 13.
