Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an intake change-over valve control device capable of switching the intake air to be introduced into an intake passage by an intake change-over valve between low-temperature air and high-temperature air, while suppressing the generation of condensed water.SOLUTION: According to one mode of the present invention, in a control device of an intake switching valve 21 for switching the intake air to be introduced into an intake passage 12 connected to an engine 11, the switching timing, at which intake air is switched between cool air and hot air by the intake switching valve 21, is judged by a water temperature Tw, and said switching timing is amended by an ambient temperature To.SELECTED DRAWING: Figure 3 【課題】凝縮水の発生を抑制しながら、吸気切替弁により吸気通路に導入する吸気を低温空気と高温空気との間で切り替えることができる吸気切替弁の制御装置を提供する。【解決手段】本発明の一態様は、エンジン１１に接続される吸気通路１２に導入する吸気をクールエアとホットエアとの間で切り替える吸気切替弁２１の制御装置において、吸気切替弁２１により吸気をクールエアとホットエアとの間で切り替える切り替えタイミングを水温Ｔｗにて判断し、前記切り替えタイミングを外気温Ｔｏにて補正する。【選択図】図３
