To provide a driving power control device of a hybrid vehicle that can satisfy requested driving power while preventing emission and fuel consumption from degrading.SOLUTION: The driving power control device of a hybrid vehicle is configured to: obtain a state of charge of a power storage device after a preset predetermined time based on requested driving power in a case where the vehicle is traveling while outputting a driving torque from an engine and a motor (step S5); and in a case where the state of charge of the power storage device after the predetermined time is less than or equal to a preset allowable lower limit of the power storage device, and more than or equal to the lowest limit smaller than the allowable lower limit (determined yes in step S8), or in a case where a time change rate of the state of charge from a time point when further becoming the lower limit or below to a time point when the predetermined time elapses is less than a predetermined change rate (determined yes in step S9), allow driving torque to be output from the motor in a state where the state of charge of the power storage device is reduced to fall below the allowable lower limit.SELECTED DRAWING: Figure 2

    【課題】エミッションや燃費が悪化することを抑制しつつ、要求駆動力を充足できるハイブリッド車両の駆動力制御装置を提供する。【解決手段】エンジンとモータとから駆動トルクを出力して走行している場合に、予め定められた所定時間後における蓄電装置の充電残量を、要求される駆動力に基づいて求め(ステップS5)、所定時間後における蓄電装置の充電残量が、予め定められた蓄電装置の許容下限値以下であり、かつ許容下限値よりも小さい値の最下限値以上である場合(ステップS8で肯定的に判断)、または更に下限値以下となった時点から所定時間が経過した時点までの充電残量の時間変化率が所定変化率未満である場合(ステップS9で肯定的に判断)に、蓄電装置の充電残量が許容下限値を超えて低下した状態でモータから駆動トルクを出力することを許容するように構成されている。【選択図】図2
