To provide electronic control equipment capable of suppressing an internal temperature rise of an enclosure, without acquiring temperature information of a blower unit.SOLUTION: A blower unit fixed to an enclosure has a fan, and a fan drive section for driving the fan based on an instruction signal. A control section controls multiple control objects including the drive section, and outputs an instruction signal to the drive section. The control section compares an internal temperature detected by a temperature detector with a predetermined internal threshold level, and when the internal temperature exceeds the internal threshold level, outputs an instruction for rotating the fan. Furthermore, in an instruction period for rotating the fan, a determination is made whether or not a thermal gradient, indicating a change of the internal temperature detected by the temperature detector, shows an increase. During a period after the determination is made that the thermal gradient shows an increase until an end of the instruction period for rotating the fan, output from the control section for the control objects other than the drive section is suppressed before a determination section determines that the thermal gradient shows an increase.SELECTED DRAWING: Figure 4 【課題】送風ユニットの温度情報を取得することなく、筐体の内部温度の上昇を抑制できる電子制御装置を提供すること。【解決手段】筐体に固定された送風ユニットは、ファン、指示信号に基づいてファンを駆動させるファン駆動部を有する。制御部は、駆動部を含む複数の制御対象を制御し、駆動部に指示信号を出力する。制御部は、温度検出部により検出された内部温度と所定の内部閾値とを比較し、内部温度が内部閾値を超えた場合に、ファンを回転させる指示を出力する。また、ファンを回転させる指示期間において、温度検出部により検出された内部温度の変化を示す温度勾配が上昇を示すか否かを判定し、温度勾配が上昇を示すと判定されてからファンを回転させる指示期間が終了するまでの間、判定部が上昇を示すと判定する前よりも、駆動部を除く制御対象に対する制御部の出力を抑制させる。【選択図】図４
