To provide a data collection method capable of increasing the probability of data acquisition from in-vehicle terminals.SOLUTION: A data collection method for identifying a given in-vehicle terminal and requesting data from the identified in-vehicle terminal, causes a computer to execute the steps of: storing an identifier of an in-vehicle terminal that does not respond to a data request in the storage unit; determining whether the identifier of the in-vehicle terminal is stored in the storage unit in response to access from any in-vehicle terminal; and requesting data again from the in-vehicle terminal related to the identifier when determined that the identifier is stored in the storage unit.SELECTED DRAWING: Figure 5

    【課題】車載端末からのデータの取得確率を高めること。【解決手段】所定の車載端末を特定し、特定された車載端末に対してデータを要求するデータ収集方法は、データの要求に対して応答しない車載端末の識別子を記憶部に記憶する処理と、いずれかの車載端末からのアクセスに応じ、当該車載端末の識別子が前記記憶部に記憶されているか否かを判定する処理と前記記憶部に前記識別子が記憶されていると判定された場合に、当該識別子に係る車載端末に対してデータを再要求する処理と、をコンピュータが実行する。【選択図】図5
