To provide an electronic control device that is able to prevent failure in control of a drive source for traveling.SOLUTION: An electronic control device 10 comprises: a housing: a blower fan 100 provided in the housing; a first temperature detection unit 74 and a second temperature detection unit 71a that detect temperatures in the housing; and a control unit 70 accommodated in the housing. The control unit 70 controls an engine in the vehicle, and outputs an indication signal to the blower fan 100 in order to cool the housing in a case where a detection result from the first temperature detection unit 74 is equal to or higher than a threshold. Then, the control unit 70 determines if either the first temperature detection unit 74 or the second temperature detection unit 71a is in an abnormal state or not. If either one of them is determined to be in an abnormal state, the control unit reduces output from the control unit 70 during engine control, compared to a case where neither of them is determined to be in abnormal state.SELECTED DRAWING: Figure 1
【課題】走行駆動源の制御に不具合が生じることを抑制できる電子制御装置を提供すること。【解決手段】電子制御装置10は、筐体と、筐体に設けられた送風ファン100と、筐体内の温度を検出する第1温度検出部74及び第2温度検出部71aと、筐体に収容された制御部70とを備えている。制御部70は、車両におけるエンジンの制御を行うとともに、第1温度検出部74の検出結果が閾値以上の場合に筐体を冷却するために送風ファン100に指示信号を出力する。そして、制御部70は、第1温度検出部74と第2温度検出部71aのいずれかが異常であるか否かを判定し、異常と判定すると、異常と判定していない場合よりもエンジンの制御時における制御部70の出力を抑制させる。【選択図】図1
