To provide a control device for a vehicular air conditioner for stopping a compressor only when a high pressure cut being a predetermined number or more is recognized without including a high pressure cut due to an increase in refrigerant pressure during acceleration and an uphill in counting.SOLUTION: A control device for driving and stopping a compressor 3 in accordance with a refrigerant pressure state in the compressor 3 used for a vehicular air conditioning system includes vehicle speed information acquisition means 20 for acquiring vehicle speed information from a vehicle speed sensor, engine speed information acquisition means 21 for acquiring engine speed information from an engine speed sensor, and high pressure cut counter 22 for counting the number of times of high pressure cuts in the case that the vehicle speed acquired from the vehicle speed information acquisition means 20 is a predetermined value or more and that the engine speed acquired from the engine speed information acquisition means 21 is a prescribed value or less, and performs control to stop driving of the compressor 3 for a prescribed period on condition that a count number of the high pressure cut counter 22 reaches the predetermined number of times.SELECTED DRAWING: Figure 5

    【課題】加速時や登坂時の冷媒圧力の上昇による高圧カットはカウントに含めず、既定数以上の高圧カットが認められた場合のみコンプレッサを停止する車両用エアコンディショナの制御装置を提供する。【解決手段】車両のエアコンシステムに用いられるコンプレッサ3内の冷媒圧力状態に応じてコンプレッサ3の駆動・停止を行う制御装置において、車速センサから車速情報を入手する車速情報入手手段20と、エンジン回転数センサからエンジン回転数情報を入手するエンジン回転数情報入手手段21と、前記車速情報入手手段20から得られた車速が既定値以上の場合、かつ、該エンジン回転数情報入手手段21から得られたエンジン回転数が既定値以下の場合の高圧カットの回数をカウントする高圧カットカウンタ22とを備え、前記高圧カットカウンタ22のカウント数が既定回数に達したことを条件として、前記コンプレッサ3の駆動を所定の間停止する制御を行う。【選択図】図5
