Summary:To provide a technology that enables efficient data usage in a vehicle network.SOLUTION: An on-vehicle device 30 is mounted on a vehicle and includes a primary data acquisition unit 31, an on-vehicle primary database 35, a first application execution unit 38, an on-vehicle secondary database 36, and a second application execution unit 39. The first application execution unit executes a first application program to calculate secondary data from primary data stored in the on-vehicle primary database. The second application execution unit executes a second application program and uses the secondary data stored in the on-vehicle secondary database.SELECTED DRAWING: Figure 7 【課題】車両ネットワークにおいて効率的にデータを利用可能な技術を提供する。【解決手段】車載機３０は、車両に搭載され、１次データ取得部３１と、車載１次データベース３５と、第１アプリ実行部３８と、車載２次データベース３６と、第２アプリ実行部３９と、を備える。第１アプリ実行部は、第１アプリケーションプログラムを実行して、車載１次データベースに記憶されている１次データから２次データを算出する。第２アプリ実行部は、第２アプリケーションプログラムを実行して、車載２次データベースに記憶されている第２次データを利用する。【選択図】図７
