Zusammenfassung:	To provide an electronic controller capable of improving the accuracy of F/B control of an actuator and reducing processing loads of a processor.SOLUTION: An electronic controller (on-vehicle electronic control unit 1) includes: a processor (CPU 102) which performs software F/B control of an actuator 3; and an F/B circuit (hardware F/B control part 201) which performs hardware F/B control of the actuator 3. The processor switches between the software F/B control and the hardware F/B control in accordance with processing loads of the processor (system processing loads) and a measurement value of sensors (various sensors 2) in a normal mode indicating a state in which scheduled processing is executed.SELECTED DRAWING: Figure 1 【課題】アクチュエータのF/B制御の精度を向上し、プロセッサの処理負荷を低減することができる電子制御装置を提供する。【解決手段】電子制御装置（車載電子制御ユニット１）は、アクチュエータ３のソフトウェアF/B制御を行うプロセッサ（ＣＰＵ１０２）と、アクチュエータ３のハードウェアF/B制御を行うF/B回路（ハードウェアF/B制御部２０１）と、を備える。プロセッサは、定時処理が実行されている状態を示す通常モードにおいて、プロセッサの処理負荷（システム処理負荷）とセンサ（各種センサ２）の測定値に応じて、ソフトウェアF/B制御とハードウェアF/B制御を切り替える。【選択図】図１
