Title (EN) ELECTRONIC CONTROL DEVICE AND CONTROL PROGRAM VERIFICATION METHOD
(FR) DISPOSITIF DE COMMANDE ÉLECTRONIQUE ET PROCÉDÉ DE VÉRIFICATION DE PROGRAMME DE COMMANDE
(JA) 電子制御装置及び制御プログラム検証方法
Abstract:
(EN) An electronic control device is provided with: a first nonvolatile memory to which a control program can be written; a second nonvolatile memory to which an identifier for verifying the correctness of the control program can be written; and a processor. In accordance with a write state of the identifier in the second nonvolatile memory, the processor selects either an identifier stored in advance in the control program or the identifier written to the second nonvolatile memory, and verifies the correctness of the control program.
(FR) L’invention concerne un dispositif de commande électronique comprenant : une première mémoire non volatile dans laquelle un programme de commande peut être écrit ; une seconde mémoire non volatile dans laquelle un identifiant permettant de vérifier l'exactitude du programme de commande peut être écrit ; et un processeur. Conformément à un état d'écriture de l'identifiant dans la seconde mémoire non volatile, le processeur sélectionne soit un identifiant stocké à l'avance dans le programme de commande, soit l'identifiant écrit dans la seconde mémoire non volatile, puis vérifie l'exactitude du programme de commande.
(JA) 電子制御装置は、制御プログラムが書き込み可能である第1の不揮発性メモリと、制御プログラムの正誤を検証する識別子が書き込み可能である第2の不揮発性メモリと、プロセッサと、を備えている。そして、プロセッサは、第2の不揮発性メモリにおける識別子の書き込み状態に応じて、制御プログラムに予め格納された識別子又は第2の不揮発性メモリに書き込まれた識別子のいずれかを選択して、制御プログラムの正誤を検証する。
