To provide a hybrid-vehicular control apparatus that suppresses the deterioration of durability of a supercharger compressor and reduction of output of the vehicle.SOLUTION: A control apparatus includes: an internal combustion engine that includes an engine body, a supercharger including a compressor disposed on an air-intake passage connected to the engine body, a recirculation passage for introducing a blow-by gas generated in the engine body to the air-intake passage on downstream of the compressor, and an introduction passage for introducing new air to the engine body from the air-intake passage on upstream than the compressor; and a motor that assists driving of the internal combustion engine. The control apparatus further includes: a determination part that determines whether or not a moisture contained in the blow-by gas flowing through the new air introduction passage is frozen, on the basis of an external air temperature in the case where a required operating point of the internal combustion engine is in a supercharging region; and a drive control part that performs control so that the operating point of the internal combustion engine is located closer to a natural air-intake region in the case where positive determination is made by the determination part compared with the case where negative determination is made, and increases output for assisting driving of the internal combustion engine by the motor.SELECTED DRAWING: Figure 4
【課題】過給機コンプレッサの耐久性低下と車両出力低下を抑制するハイブリッド車両の制御装置を提供する。【解決手段】機関本体、前記機関本体に接続された吸気通路上に配置されたコンプレッサを含む過給機、前記機関本体で発生したブローバイガスを前記コンプレッサの下流側の前記吸気通路に導く還流通路、及び前記コンプレッサよりも上流側の前記吸気通路から前記機関本体に新気を導く導入通路、を有した内燃機関と、前記内燃機関の駆動をアシストするモータと、を備え、前記内燃機関の要求動作点が過給領域にある場合に、外気温に基づいて前記新気導入通路を流れるブローバイガス中の水分が凍結するか否かを判定する判定部と、前記判定部により肯定判定がなされた場合には、前記内燃機関の動作点を否定判定がなされた場合よりも自然吸気領域側となるように制御し、且つ前記モータによる前記内燃機関の駆動をアシストするための出力を増大させる。【選択図】図4
