To provide a warming-up device of an internal combustion engine mounted vehicle for increasing an output load of an internal combustion engine without excessive exhaust gas exergy, efficiently activating a catalyst, and properly increasing temperature of a compartment during warming-up by a required minimum additional operation of the internal combustion engine.SOLUTION: A control part includes: storage means for storing an exhaust gas exergy map; determination means R1 for determining whether exhaust gas from an internal combustion engine has target gas temperature not less than active temperature of a catalyst and a target gas flow rate required for auxiliary warming the compartment using recovery heat of an exhaust heat recover unit under a certain vehicle travelling condition; internal combustion engine control means S8 for increasing temperature of the exhaust gas to the target gas temperature to solve a difference in a magnitude direction of a load by operating the internal combustion engine at the identical rotation number and with an increased output load when it is determined that the target gas temperature is not satisfied; and electric temperature increasing unit control means S9 for increasing temperature of the compartment by driving a power generator with an increased output due to the control means S8, and activating the electric temperature increasing unit.SELECTED DRAWING: Figure 6
【課題】内燃機関の必要最低限の追加運転により、排ガスエクセルギが過剰とならないよう内燃機関の出力負荷を増大し、効率よく触媒活性化を図ると共に、暖房時の車室温度を適切に昇温する内燃機関搭載車両の暖機装置を提供する。【解決手段】排ガスエクセルギマップを記憶する記憶手段と、ある車両走行状態で内燃機関からの排ガスが触媒の活性温度以上の目標ガス温度と排熱回収器の回収熱を使用した車室補助暖房に必要な目標ガス流量を有するか否かを、負荷の大きさと出力軸回転数の方向で差分をとって判定する判定手段R1と、目標ガス温度を満たさないと判定した時、内燃機関を同一回転数で出力負荷を増して運転させて負荷の大きさ方向の差分を解消すべく排ガスを目標ガス温度に昇温させる内燃機関制御手段S8と、この制御手段S8による増加出力で発電機を駆動し、電気昇温器を作動させて車室を昇温する電気昇温器制御手段S9とを含む制御部を有する。【選択図】図6
