Zusammenfassung:	To prevent freezing in an intake pipe downstream of an air cleaner.SOLUTION: A hybrid vehicle comprises: an engine; a first motor capable of generating electricity using power from the engine; a second motor capable of outputting power for traveling; and a controller for controlling the engine, the first motor and the second motor. The controller changes an operating point of the engine to a non-supercharged region when an ambient temperature is less than a predetermined temperature, the vehicle speed is greater than or equal to a predetermined speed, and the intake air pressure is greater than or equal to a predetermined pressure. This can prevent a reverse flow of blow-by gas into an intake pipe downstream of an air cleaner, and can prevent water vapor contained in the blow-by gas that has flowed into the intake pipe from freezing in the intake pipe.SELECTED DRAWING: Figure 2 【課題】エアクリーナの下流側の吸気管内での凍結を防止する。【解決手段】ハイブリッド車は、エンジンと、エンジンからの動力を用いて発電可能な第１モータと、走行用の動力を出力可能な第２モータと、エンジンと第１モータと第２モータとを制御する制御装置とを備える。制御装置は、外気温が所定温度未満で車速が所定車速以上で吸気圧が所定圧以上のときには、前記エンジンの動作点を非過給領域に変更する。これにより、ブローバイガスが逆流してエアクリーナの下流側の吸気管内に流入するのを抑止し、吸気管内に流入したブローバイガスに含まれる水蒸気が吸気管内で凍結するのを防止することができる。【選択図】図２
