ELECTRONIC CONTROL DEVICE, WORK VEHICLE, AND INPUT CIRCUIT

To provide an electronic control device capable of reducing a power loss.SOLUTION: An electronic control device is mounted on a work vehicle that includes a switch for switching between an electrically conductive state and an electrically non-conductive state between a first terminal and a second terminal. The electronic control device includes: an input terminal that is connected to a second terminal of the switch via a conductive wire; an input circuit that is connected to the input terminal via a signal line; and a microcontroller that detects an electrically conductive state and an electrically non-conductive state of the switch based on an output signal that is output from the input circuit, and executes at least one processing step according to a detection result. The input circuit includes: a first resistive element that is connected to a power source or ground and a signal line; and a transient current circuit that is connected to the power source or ground and the signal line and includes a second resistive element that passes a transient current to the switch when the switch transitions from the electrically non-conductive state to the electrically conductive state.SELECTED DRAWING: Figure 1 【課題】電力損失を低減することが可能な電子制御装置を提供する。【解決手段】電子制御装置は、第１端子と第２端子との間における電気的導通状態と電気的不導通状態とを切り替えるスイッチを備える作業車両に搭載される。電子制御装置は、導電線を介してスイッチの第２端子に接続される入力端子と、入力端子に信号線を介して接続される入力回路と、入力回路から出力される出力信号に基づいてスイッチの電気的導通状態および電気的不導通状態を検知して、検知結果に応じた少なくとも１つの処理を実行するマイクロコントローラとを備える。入力回路は、電源またはグランドと信号線とに接続される第１抵抗素子と、電源またはグランドと信号線とに接続される過渡電流回路であって、スイッチが電気的不導通状態から電気的導通状態に遷移するときにスイッチに過渡電流を流す第２抵抗素子を含む過渡電流回路とを有する。【選択図】図１
