PROBLEM TO BE SOLVED: To provide a rewrite system capable of shortening time to rewrite, and to provide a rewrite device and a computer used for the rewrite system.SOLUTION: A rewrite device rewrites storage contents stored in a plurality of ECUs. Each of the plurality of ECUs includes a common rewrite subject area A2 in which common storage contents that are common to one another are stored, and a non-common rewrite subject area A3 in which non-common storage contents that are uncommon to one another are stored. The rewrite device collectively sends the rewrite data of the common storage contents to the plurality of ECUs, whilst the same sequentially sends the rewrite data of the non-common storage contents to the ECUs subject to rewrite.SELECTED DRAWING: Figure 2
【課題】書き換え時間を短縮できる書換えシステム、当該書換えシステムに用いられる書換え装置及びコンピュータを提供する。【解決手段】書換え装置が、複数のECUに記憶された記憶内容を書き換える。複数のECUが各々、互いに共通の共通記憶内容が記憶される共通書換え対象エリアA2と、互いに共通ではない非共通記憶内容が記憶される非共通書換え対象エリアA3と、を有する。書換え装置が、共通記憶内容の書換えデータを複数のECUに対して一括送信すると共に、非共通記憶内容の書換えデータを書換え対象のECUに対して順次送信する。【選択図】図2
