PROBLEM TO BE SOLVED: To provide an on-vehicle update system, on-vehicle update device and gateway which can prevent the operation of other on-vehicle equipment from being adversely affected by update processing of on-vehicle equipment.SOLUTION: An on-vehicle update system includes: on-vehicle equipment which periodically performs data transmission to a communication line arranged in a vehicle; an on-vehicle update device which is connected to the communication line and performs update processing of a program stored in a storage unit of the on-vehicle equipment; and a substitution unit which substitutes for the periodical data transmission by the on-vehicle equipment when the on-vehicle update device performs the update processing. The on-vehicle update system includes a data storage unit which stores data for substitution transmission, and the substitution unit may periodically transmit the data stored in the data storage unit. The on-vehicle update system includes a data acquisition unit which acquires data periodically transmitted from the on-vehicle equipment, and the data storage unit may store the data acquired by the data acquisition unit.SELECTED DRAWING: Figure 3
【課題】車載機器の更新処理を行うことが他の車載機器の動作に悪影響を及ぼすことを防止し得る車載更新システム、車載更新装置及びゲートウェイを提供する。【解決手段】本実施の形態に係る車載更新システムは、車両に配された通信線へ定期的にデータ送信を行う車載機器と、前記通信線に接続され、前記車載機器の記憶部に記憶されたプログラムの更新処理を行う車載更新装置とを備える車載更新システムであって、前記車載更新装置が前記更新処理を行う場合に、前記車載機器による定期的なデータ送信を代替する代替部を備える。車載更新システムは、代替送信用のデータを記憶するデータ記憶部を備え、前記代替部が前記データ記憶部に記憶されたデータを定期的に送信してもよい。車載更新システムは、前記車載機器が定期的に送信するデータを取得するデータ取得部を備え、前記データ記憶部が前記データ取得部が取得したデータを記憶してもよい。【選択図】図3
