To provide an electronic control unit capable of transferring a message to another ECU which can process the message, and capable of transmitting a message processing result to the source of the message transmission.SOLUTION: An ECU 10, connected in series to an upstream side ECU and a downstream side ECU, includes: an upstream side communication part for receiving a message including a predetermined condition and request content requesting a predetermined operation if the predetermined condition is satisfied from the upstream side ECU; a condition determination part for determining whether the condition is satisfied; a request content determination part for determining whether the request content is satisfied; and a downstream side communication part for transmitting a condition determination result indicating that the condition is satisfied and a message to the downstream side ECU if the condition determination part determines that the condition is satisfied. The upstream side communication part transmits a content determination result indicating that the request content is satisfied to the upstream side ECU if the request content determination part determines that the request content is satisfied and a condition determination result indicating that the condition is satisfied is received by the upstream side communication part from the upstream side ECU or by the downstream side communication part from the downstream side ECU.SELECTED DRAWING: Figure 2
【課題】メッセージを処理可能なECUへと転送するとともに、メッセージの処理結果を当該メッセージの送信元に送信する電子制御装置を提供する。【解決手段】上流側ECU及び下流側ECUに直列に接続されたECU10であって、上流側ECUから、所定の条件と条件を満たす場合に所定の動作を要求する要求内容を含むメッセージを受信する上流側通信部と、条件を満たすか否かを判定する条件判定部と、要求内容を満たすか否かを判定する要求内容判定部と、条件判定部が条件を満たすと判定した場合に、条件を満たすことを示す条件判定結果及びメッセージを下流側ECUに送信する下流側通信部とを備える。要求内容判定部が要求内容を満たすと判定し、且つ上流側通信部が上流側ECUから又は下流側通信部が下流側ECUから条件を満たすことを示す条件判定結果を受信した場合、上流側通信部は要求内容を満たすことを示す内容判定結果を上流側ECUに送信する。【選択図】図2
