PROBLEM TO BE SOLVED: To suppress the frequent repetition of starting and stopping an internal combustion engine for heating the cabin of a hybrid electric vehicle.SOLUTION: A hybrid electric vehicle air conditioning control unit intermittently actuates an engine with optimum fuel economy so that a coolant temperature of the engine is kept in a predetermined heating temperature range in response to a heating request. Furthermore, the air conditioning control unit switches over between outdoor air circulation and indoor air circulation so that a humidity of a cabin is kept in a predetermined humidity range. The inside air circulation is kept as long as the humidity of the cabin does not exceed the predetermined humidity range, thereby suppressing a temperature reduction of the cabin and increasing the interval between actuation and stop of the engine. Moreover, it is possible to make effective use of energy by using an output of the internal combustion engine generated by actuating the engine with the optimum fuel economy for charging a power storage device.

    【課題】ハイブリッド車両の車室暖房のための内燃機関の始動と停止の頻繁な繰り返しを抑制する。【解決手段】ハイブリッド車両の空調制御装置は、暖房要求に対してエンジンの冷却水温度が所定の暖房温度領域に維持されるよう、エンジンを断続的に最適燃費運転する。また、車室の湿度が所定の湿度領域に維持されるよう、外気循環と内気循環とを切り換える。車室の湿度が所定の湿度領域を超えない限り内気循環を維持することで、車室の温度低下を抑制し、エンジンの運転と停止のインターバルを長くする。さらに、最適燃費運転による内燃機関出力を蓄電装置の充電に用いることでエネルギーを有効に利用できる。【選択図】図6
