PROBLEM TO BE SOLVED: To provide an on-vehicle update device and an on-vehicle update system for preventing storage electric energy of a battery from being drastically reduced with update processing.SOLUTION: An on-vehicle update device comprises an update processing section for performing processing to update a program or data stored in a storage section of a communication apparatus mounted on a vehicle. The device also comprises: an update information acquisition section for performing processing to acquire an update program or data from a device on the outer side of a vehicle; a required electric energy estimation section for estimating electric energy to be required for update processing using the update program or data acquired by the update information acquisition section; and a battery electric energy acquisition section for acquiring electric energy stored in a battery of a vehicle. The update processing section performs update processing in accordance with electric energy estimated by the required electric energy estimation section, electric energy acquired by the battery electric energy acquisition section, and a priority of the update program or data acquired by the update information acquisition section.SELECTED DRAWING: Figure 3

    【課題】更新処理に伴ってバッテリの蓄積電力量が著しく低下することを防止する車載更新装置及び車載更新システムを提供する。【解決手段】車両に搭載された通信装置の記憶部に記憶されたプログラム又はデータを更新する処理を行う更新処理部を備える車載更新装置であって、車両外の装置から更新用のプログラム又はデータを取得する処理を行う更新用情報取得部と、更新用情報取得部が取得した更新用のプログラム又はデータを用いた更新処理に必要な電力量を推定する必要電力量推定部と、車両のバッテリに蓄積された電力量を取得するバッテリ電力量取得部とを備える。更新処理部は、必要電力量推定部が推定した電力量、バッテリ電力量取得部が取得した電力量及び更新用情報取得部が取得した更新用のプログラム又はデータの優先度に応じて、更新処理を行う。【選択図】図3
