To provide a brake negative pressure control apparatus capable of inhibiting deterioration of NVH performance.SOLUTION: The brake negative pressure control apparatus comprises a control unit. When a negative pressure in a negative pressure chamber of a brake booster becomes lower than a predetermined negative pressure, the control unit drives MG1 to rotate a crankshaft of an engine so as to restore the negative pressure in the negative pressure chamber. The control unit sets the predetermined negative pressure so as to increase the predetermined negative pressure, as the volume of noise transmitted from the vehicle into the vehicle interior increases.SELECTED DRAWING: Figure 2

    【課題】NVH性能が低下することを抑制することができるブレーキ負圧制御装置を提供すること。【解決手段】ブレーキブースタの負圧室内の負圧が所定負圧よりも低くなると、MG1を駆動させることによってエンジンのクランクシャフトを回転させて負圧室内の負圧を回復させる制御部を備え、制御部は、車両から車室内に伝わっている音の大きさが大きくなるに連れて高くなるように所定負圧を設定する。【選択図】図2
