Summary:To achieve adaptive control of a servo motor while suppressing generation of a cost increase.SOLUTION: An auto air-conditioner ECU 30 executes drive control intended for a servo motor 21 for blowout mode door drive installed on an automatic air-conditioner 1 and driven by a battery. Specifically, the auto air-conditioner ECU 30 detects a rotational position of the servo motor 21 for blowout mode door drive and when the detected rotational position enters a designated range including a target position, stops the servo motor 21 for blowout mode door drive. The auto air-conditioner ECU 30 also changes an area of the designated range according to a vehicle state (a voltage value of a battery and air volume of a blower 4).SELECTED DRAWING: Figure 1 【課題】コストを抑えつつ、サーボモータを適応的に制御すること。【解決手段】オートエアコンＥＣＵ３０は、オートエアコン１に設けられかつバッテリによって駆動される吹出モードドア駆動用サーボモータ２１を対象として、駆動制御を行う。具体的には、オートエアコンＥＣＵ３０は、吹出モードドア駆動用サーボモータ２１の回転位置を検出し、検出された回転位置が目標位置を含む指定範囲に入ったとき吹出モードドア駆動用サーボモータ２１を停止させる。オートエアコンＥＣＵ３０はまた、車両状態（バッテリの電圧値およびブロア４の風量）に応じて指定範囲の広さを変更する。【選択図】図１
