To appropriately maintain drawing of information about safety application by a sub-electric power source while appropriately reducing unnecessary electric power consumption when an abnormality occurs in a main electric power source.SOLUTION: An integrated control ECU2 comprises: a first OS4 that provides a first function; a second OS5 that provides a second function; a first circuit block group 33 that is used in the first OS; a second circuit group 36 that is used in the second OS; a first electric power source circuit 30 that supplies a sub-electric power source to the first circuit block group; a second electric power source circuit 35, provided separately from the first electric power source circuit, which supplies a main-electric power source to the second circuit block group; and a control part 31 that maintains supply of the sub-electric power source from the first electric power source circuit to the first circuit block group when an abnormality occurs in the main electric power source and finishes operation of the second electric power source.SELECTED DRAWING: Figure 2

    【課題】メイン電源の異常時に、不要な電力消費を適切に低減しつつ、サブ電源による安全用途の情報の描画を適切に維持する。【解決手段】統合制御ECU2は、第1の機能を提供する第1のOS4と、第2の機能を提供する第2のOS5と、第1のOSで使用される第1の回路ブロック群33と、第2のOSで使用される第2の回路ブロック群36と、第1の回路ブロック群にサブ電源を供給する第1の電源回路30と、第1の電源回路から分離して設けられ、第2の回路ブロック群にメイン電源を供給する第2の電源回路35と、メイン電源の異常時に、第1の電源回路から第1の回路ブロック群へのサブ電源の供給を維持すると共に、第2の電源回路の動作を終了させる制御部31と、を備える。【選択図】図2
