To provide a program for a vehicle re-writing system that efficiently generates specification data for appropriately selecting an electronic control device to be updated and re-writing data.SOLUTION: A center device 3 indicates whether update data of a plurality of devices to be updated, target device IDs, and program storage memories for the target devices are on one surface or a plurality of surfaces, on the basis of a memory configuration referred to during update and roll back of the target devices and an address for reading out the update data, stores a distribution package including specification data and update data in which the IDs, memory configuration, and address for the target devices are generated in accordance with a predetermined data structure determined in advance, and distributes the distribution package to a vehicle-side system 4 in response to notification from the vehicle-side system (203). The vehicle-side system refers to the received distribution package and determines if writing in a memory is possible while a vehicle is traveling, controls update of a program for the target devices, and when there is a cancellation during the update, controls roll back on the basis of the memory configuration.SELECTED DRAWING: Figure 8

    【課題】更新対象の電子制御装置を適切に選択してデータを書換えるための諸元データを効率的に生成する車両用プログラム書換えシステムを提供する。【解決手段】センター装置3は、複数の更新対象装置の更新データ、対象装置ID及び対象装置のプログラム格納メモリが1面か複数面かを示し、対象装置の更新及びロールバックの際に参照されるメモリ構成と更新データを読み出すためのアドレスとに基づき、対象装置に対するID、メモリ構成及びアドレスを予め定められた所定のデータ構造に合わせて生成された諸元データと更新データとを含む配信パッケージを記憶し、車両側システム4からの通知に応じてそれを車両側システムへ配信する203。車両側システムは、受信した配信パッケージを参照して車両の走行中にメモリへの書込みが可能か否か判断し、対象装置のプログラム更新を制御し、途中でキャンセルがあるとメモリ構成に基づきロールバックを制御する。【選択図】図8
