To provide a driving force control device for a hybrid vehicle capable of executing an OBD diagnosis at an operating point of a predetermined specified operating state and maintaining accuracy of abnormality detection of the OBD diagnosis to enable accurate diagnosis.SOLUTION: A driving force control device for a hybrid vehicle performs line trace control for controlling a value of a yaw rate that is a change rate of a yaw angle during turning to a target value. The hybrid vehicle includes a controller that controls an operating point of an operating state determined by engine torque and engine speed. The driving force control device for the hybrid vehicle includes: diagnosis request determination means for determining that a diagnosis of abnormality determination of an engine is requested; line trace control request means for determining satisfaction of a control request of the engine torque through the line trace control; and line trace control prohibition means for prohibiting the control of the engine torque through the line trace control when both of the diagnosis request determination means and the line trace control request means are satisfied.SELECTED DRAWING: Figure 2

    【課題】OBD診断を予め定めた所定の運転状態の動作点で実行し、OBD診断の異常検出の精度を維持させて正確に診断することが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】旋回時のヨー角の変化率であるヨーレートの値を、目標値に制御するライントレース制御を備えたハイブリッド車両の駆動力制御装置であって、前記ハイブリッド車両は、エンジントルクとエンジン回転数とで定まる運転状態の動作点を制御するコントローラを備え、前記エンジンの異常判定の診断が要求されていることを判断する診断要求判断手段と、前記ライントレース制御による前記エンジントルクの制御要求が成立したことを判断するライントレース制御要求手段と、前記診断要求判断手段と前記ライントレース制御要求手段とのどちらも成立した場合に、前記ライントレース制御による前記エンジントルクの制御を禁止するライントレース制御禁止手段とを備えている。【選択図】図2
