PROBLEM TO BE SOLVED: To make is possible to shorten the time required for reprogramming while reducing labor without limiting a reprogrammable range of an on-vehicle electronic control device.SOLUTION: A target ECU 2 connected to an on-vehicle network includes: a control unit 24 configured to perform reprogramming for rewriting a control program stored in a nonvolatile memory 22 to a rewriting target control program to be received from a Tester 5; and a communication unit 21 configured to perform communication by switching between a normal mode for communicating with a non-target ECU connected to the on-vehicle network in accordance with a common standard and a special mode for performing communication with an upper-grade standard having a communication speed higher than that in the common standard. The communication unit 21, when it receives information that designates reprogramming of the own device via the on-vehicle network, switches from the normal mode to the special mode and receives a computer program to be rewritten.SELECTED DRAWING: Figure 2

    【課題】車載の電子制御装置のリプログラミング可能な範囲を制限することなく、手間を抑えてリプログラミングに要する時間を短縮することを可能にする。【解決手段】車載ネットワークに接続される対象ECU2であって、不揮発性メモリ22に記憶している制御プログラムを、Tester5から受信する書換対象の制御プログラムに書き換えるリプログラミングを行う制御部24と、車載ネットワークに接続される対象外ECUと共通の規格で通信を行う通常モードと、その規格での通信よりも通信速度の速い上位規格で通信を行う特別モードとを切り替えて通信可能な通信部21とを備え、通信部21は、車載ネットワークを介して自装置のリプログラミングを指定する情報を受信した場合には、通常モードから特別モードに切り替えて、書換対象のコンピュータプログラムを受信する。【選択図】図2
