PROBLEM TO BE SOLVED: To provide an electronic control device which can surely prevent the occurrence of a phenomenon that a task is not executed in a specified phase accompanied by the changeover of a cores for executing the task, and the duplicate execution of the task.SOLUTION: This electronic control device 10 comprises a microcomputer 100 mounted with a plurality of cores C1, C2, and executes a synchronous task in synchronization with a phase of a rotation angle in the cores C1, C2. The electronic control device 10 comprises a first storage part 131 which stores a core number indicating the synchronization task execution core, and a second storage part 132 which stores a changeover phase indicating a phase when the synchronization task execution core is switched. The electronic control device 10 switches the synchronization task execution core on the basis of the core number which is stored in the first storage part 131 and the changeover phase which is stored in the second storage part 132.SELECTED DRAWING: Figure 1 【課題】タスクを実行するコアの切り替えに伴い、特定の位相においてタスクが実行されない現象や、タスクが重複して実行されてしまう現象を確実に防止することのできる電子制御装置を提供する【解決手段】この電子制御装置１０は、複数のコアＣ１、Ｃ２を搭載したマイコン１００を備えており、コアＣ１、Ｃ２において、回転角の位相に同期して同期タスクを実行する。電子制御装置１０は、同期タスク実行コアを示すコア番号を記憶する第１記憶部１３１と、同期タスク実行コアの切り替えが行われる際の位相、を示す切り替え位相を記憶する第２記憶部１３２と、を備えている。電子制御装置１０は、第１記憶部１３１に記憶されているコア番号、及び、第２記憶部１３２に記憶されている切り替え位相に基づいて、同期タスク実行コアの切り替えを行う。【選択図】図１
