VEHICULAR AIR-CONDITIONER CONTROL APPARATUS

PROBLEM TO BE SOLVED: To maintain the atmosphere inside a cabin comfortable regardless of the travel condition of the vehicle.SOLUTION: A vehicular air-conditioner control apparatus 11 includes: an information obtainment part 41 for obtaining information on negative pressure related to a booster 23 that provides brake assistance force using intake negative pressure of an engine 13 and information related to temporal variation of brake hydraulic pressure; a determination part 43 for determining whether the information on negative pressure related to the booster 23 is less than a negative-pressure threshold P2th and whether given variation has occurred to the brake hydraulic pressure on the basis of information on the temporal variation of the brake negative pressure; and a control part 45 for performing control to stop an operation of an air-conditioner 39 in a case where the information on negative pressure related to the booster 23 is less than a negative-pressure threshold P2th, with the determination part 43 determining that the given variation has occurred to the brake hydraulic pressure. In a case where the given variation no longer occurs to the brake hydraulic pressure while performing the control to stop the operation of the air-conditioner 39, the control part 45 performs control for recovering the operation of the air-conditioner 39.SELECTED DRAWING: Figure 1 【課題】車両の走行状況にかかわらず、車室内の雰囲気を快適に維持する。【解決手段】車両用エアコン制御装置１１は、エンジン１３の吸気負圧を用いて制動補助力を与えるブースタ２３に係る負圧の情報、及び、制動液圧の時間変動に係る情報を取得する情報取得部４１と、ブースタ２３に係る負圧の情報が負圧閾値Ｐ２ｔｈ未満か否かを判定すると共に、制動液圧の時間変動に係る情報に基づいて、制動液圧に所定の変動が生じたか否かを判定する判定部４３と、ブースタ２３に係る負圧の情報が負圧閾値Ｐ２ｔｈ未満になり、かつ、制動液圧に所定の変動が生じた旨の判定が判定部４３により下された場合に、エアコン３９の動作を停止させる制御を行う制御部４５と、を備える。制御部４５は、エアコン３９の動作を停止させる制御が行われている際に、制動液圧に所定の変動が生じなくなった場合、エアコン３９の動作を復帰させる制御を行う。【選択図】図１
