PROBLEM TO BE SOLVED: To obtain a program rewrite and verification system, in rewriting a program of a control device connected to a network, preventing a cost of one node from being high, and capable of verifying whether or not a program has been changed after rewriting.SOLUTION: A tester 3 divides a program for rewriting a program of a battery control device 1 which is a first type node, and transmits the divided program to an EPS control device 2a and a motor control device 2b, which are second type nodes, to be stored in a recording device respectively. Each second type node determines whether the divided program is transmittable, and when the divided program is determined to be transmittable, transmits the divided program to the battery control device 1. After the battery control device 1 rewrites the program, by operation state monitoring means 28 of the motor control device 2b, the operation state of the battery control device 1 is monitored, and if there is an abnormality, each of the second type node verifies the rewritten part of the battery control device 1.SELECTED DRAWING: Figure 1

    【課題】ネットワークに接続された制御装置のプログラムの書き換えに当たって、1つのノードがコスト高とならないようにするとともに、書き換えたのちにプログラムが変更されていないかどうかを検証可能なプログラム書き換え及び検証システムを得る。【解決手段】テスタ3が第1種ノードであるバッテリ制御装置1のプログラムの書き換え用プログラムを分割し、第2種ノードであるEPS制御装置2aとモータ制御装置2bに送信し、それぞれ記録装置に保存させ、各第2種ノードは、分割プログラムの送信可否を判断し、送信可の場合に分割プログラムをバッテリ制御装置1に送信し、バッテリ制御装置1がプログラムを書き換えたのちに、モータ制御装置2bの動作状態監視手段28により、バッテリ制御装置1の動作状態を監視し、異常があれば各第2種ノードでバッテリ制御装置1の書き換え部分を検証する。【選択図】図1
