Summary: | To provide an information processing device or the like capable of updating a program of a controller to be updated so as not to affect the controller.SOLUTION: An information processing device 210 includes: an ECU 230; a management ECU 220 that provides the ECU 230 with a virtual storage having a first storage area 241 and a second storage area 242 in which a first program executed by the ECU 230 at startup is stored in one of the storage areas; an update control unit 221 that acquires a second program for update of the first program from an external device and causes the acquired second program to be stored in the other storage area of the first storage area 241 and the second storage area 242; and a switching unit 222 that switches the program executed by the ECU 230 at the startup from the first program to the second program stored in the other storage area after the second program is stored in the other storage area.SELECTED DRAWING: Figure 4
【課題】更新対象の制御器のプログラムを当該制御器に影響を与えないように更新することができる情報処理装置などを提供する。【解決手段】情報処理装置210は、ECU230と、一方の記憶領域にECU230が起動時に実行する第1プログラムが格納されている、第1記憶領域241および第2記憶領域242を有する仮想ストレージをECU230に提供する管理ECU220と、外部装置から第1プログラムの更新用の第2プログラムを取得し、取得した第2プログラムを第1記憶領域241および第2記憶領域242の他方の記憶領域に格納させる更新制御部221と、第2プログラムが他方の記憶領域に格納された後で、ECU230が起動時に実行するプログラムを第1プログラムから他方の記憶領域に格納された第2プログラムに切り替える切替部222と、を備える。【選択図】図4 |
