Abstract

Official abstract text for this publication.

A data recording device of this disclosure records, in a basic recording period, a plurality of pieces of data on the state of a vehicle, the pieces of data being to be each acquired in a predetermined sampling period, the basic recording period being longer than the predetermined sampling period. The data recording device records at least one specified data specified by a vehicle external device among the pieces of data in a shortened recording period equal to or more than the predetermined sampling period but less than the basic recording period.

First claim

Opening claim text (preview).

What is claimed is: 1. A data recording device configured to: acquire a plurality of pieces of data on a state of a vehicle during a predetermined sampling period; record a first subset of the plurality of pieces of data during a basic recording period, the basic recording period being longer than the predetermined sampling period; and record a second subset of the plurality of pieces of data during a shortened recording period equal to or more than the predetermined sampling period but less than the basic recording period. 2. The data recording device according to claim 1 , wherein a management server is configured to acquire the pieces of data from the vehicle via a communications device provided in the vehicle and manage the pieces of data; and a terminal is connected to the data recording device to diagnose a malfunction in the vehicle. 3. The data recording device according to claim 1 , wherein the pieces of data are recorded regularly in the basic recording period. 4. A data recording method comprising: acquiring a plurality of pieces of data on a state of a vehicle during a predetermined sampling period; recording a first subset of the plurality of pieces of data during a basic recording period, the basic recording period being longer than the predetermined sampling period; and recording a second subset of the plurality of pieces of data during a shortened recording period equal to or more than the predetermined sampling period but less than the basic recording period.
