To provide an electronic control device capable of suppressing continuation of a high temperature state of the electronic control device and notifying a driver and a worker of a high temperature state of the electronic control device.SOLUTION: An ECU mounted on a vehicle includes a housing, a blower fan that cools the housing, an ECU temperature sensor for detecting a temperature in the housing, and a microcomputer housed in the housing and controlling driving of the blower fan and running of the vehicle. The microcomputer compares the detection result of the ECU temperature sensor with a temperature threshold value (S10). Then, when the detection result is equal to or higher than the temperature threshold value, the microcomputer drives the blower fan to cool the housing (S13). Further, when the detection result is equal to or higher than the temperature threshold value, the microcomputer performs at least one of notification of a high temperature state of the ECU and storage in a checkable state (S11, S12).SELECTED DRAWING: Figure 4

    【課題】電子制御装置の高温状態が継続されることを抑制するとともに、電子制御装置が高温状態であることを運転者や作業者に知らせることができる電子制御装置を提供すること。【解決手段】ECUは、車両に搭載されるものであって、筐体と、筐体を冷却する送風ファンと、筐体内の温度を検出するECU温度センサと、筐体に収容され送風ファンの駆動制御及び車両の走行制御を行うマイコンと、を備えている。マイコンは、ECU温度センサの検出結果と温度閾値とを比較する(S10)。そして、マイコンは、検出結果が温度閾値以上の場合、筐体を冷却するために送風ファンを駆動させる(S13)。さらに、マイコンは、検出結果が温度閾値以上の場合、ECUが高温状態であることを知らせるための報知と確認可能な状態での記憶の少なくとも一方を行う(S11、S12)。【選択図】図4
