PROBLEM TO BE SOLVED: To provide a drive force control apparatus capable of causing a vehicle to travel in re-acceleration by setting an appropriate gear stage with the driving intention of a driver reflected.SOLUTION: A drive force control apparatus of a vehicle that is incorporated with an engine and an automatic transmission and controls drive force on the basis of a vehicular speed and an accelerator opening degree, performs: estimating, as a target vehicular speed for a re-acceleration travel after a deceleration travel of the vehicle, an expected vehicular speed desired by a driver for the re-acceleration travel, on the basis of a travel state amount in an acceleration travel prior to the deceleration travel; calculating a reacceleration-applicable acceleration to be used as a control indicator for the re-acceleration travel, on the basis of the present vehicular speed during the deceleration travel and the expected vehicular speed; setting a speed change ratio of the automatic transmission enabling the reacceleration-applicable acceleration before starting the re-acceleration travel; and updating the expected vehicular speed on the basis of the travel state amount in a case where an acceleration distance during the re-acceleration travel is longer than a given distance α (steps S104, S105).SELECTED DRAWING: Figure 12

    【課題】運転者の運転志向を反映した適切な変速段を設定して車両を再加速走行させることができる駆動力制御装置を提供する。【解決手段】エンジンおよび自動変速機を搭載し、車速およびアクセル開度に基づいて駆動力を制御する車両の駆動力制御装置において、前記車両が減速走行した後に再加速走行をする際の目標車速として、前記減速走行する以前の加速走行時における走行状態量に基づいて、前記再加速走行する際に運転者が所望する期待車速を推定し、前記減速走行中の現在車速および前記期待車速に基づいて、前記再加速走行する際の制御指標とする再加速時加速度を求め、前記再加速走行を開始する前に、前記再加速時加速度を実現可能な前記自動変速機の変速比を設定し、前記加速走行時の加速距離が所定距離αよりも長い場合に、前記走行状態量に基づいて、前記期待車速を更新する(ステップS104,S105)。【選択図】図12
