To provide a control method for a vehicle air conditioner, which is highly compatible to a conventional vehicle using power as an engine and which can adjust both a temperature of air blown out from a bent outlet and a temperature of air blown out from a foot outlet to a target temperature while adding an upper-lower temperature difference in a bi-level mode through easy control independent of a refrigerant circulation circuit, and the vehicle air conditioner.SOLUTION: In a control method for a vehicle air conditioner, an air-conditioning control device 20 executes: a bi-level mode recognition step of recognizing that a blowing mode is a bi-level mode; a foot temperature adjustment step of adjusting a heat generation amount of a liquid heating device 12 so that a temperature detected by a foot temperature detection device 42 can reach a set target temperature; and a bent temperature adjustment step of adjusting a discharge amount of a pump 11 so that a temperature detected by a bent temperature detection device 41 can reach a set target temperature after the foot temperature adjustment step.SELECTED DRAWING: Figure 1

    【課題】本開示は、従来の動力をエンジンとする車両との互換性が高く、冷媒循環回路と独立した容易な制御によって、バイレベルモードにおいて上下温度差を付与しながら、ベント吹出口から吹出される空気の温度及びフット吹出口から吹出される空気の温度の両方を目標温度に調整することができる車両用空調装置の制御方法及び車両用空調装置を提供することを目的とする。【解決手段】本開示に係る車両用空調装置の制御方法は、空調制御装置20が、吹出モードがバイレベルモードであることを認識するバイレベルモード認識工程と、フット温度検知装置42が検知する温度が設定された目標温度になるように液体加熱装置12の発熱量を調整するフット温度調整工程と、フット温度調整工程の後、ベント温度検知装置41が検知する温度が設定された目標温度になるようにポンプ11の吐出量を調整するベント温度調整工程と、を実行する。【選択図】図1
