To provide a vehicle driving support device which performs travel support control capable of improving energy efficiency of a driving device while suppressing feeling of excessive deceleration or acceleration that a driver of an own vehicle may have.SOLUTION: A vehicle driving support device 10 executes an extended constant speed travel control where a vehicle speed is kept at a preset vehicle speed in which: when vehicle speed is faster than an upper limit value in an extended vehicle speed control range including the preset vehicle speed, an own vehicle 100 is decelerated; and when the vehicle speed is slower than a lower limit value in the extended vehicle speed control range, the own vehicle is accelerated. The vehicle driving support device sets, when the preset vehicle speed is a prescribed vehicle speed or less during the execution of the extended constant speed travel control, the lower limit value in the extended vehicle speed control range to reduce a difference between the lower limit value in the extended vehicle speed control range and the preset vehicle speed in comparison with a case that the preset vehicle speed is faster than the prescribed vehicle speed, or accelerates the own vehicle by a smaller drive force compared with a drive force where a driving device is activated at the optimized energy efficiency.SELECTED DRAWING: Figure 16

    【課題】自車両の運転者が過剰な減速又は加速が行われていると感じることを抑制しつつ、駆動装置のエネルギー効率を向上することができるように走行支援制御を実行する車両運転支援装置を提供する。【解決手段】車両運転支援装置10は、設定車速を含む拡大車速制御範囲の上限値よりも大きくなった場合、自車両100を減速させ、車速が拡大車速制御範囲の下限値よりも小さくなった場合、自車両を加速させることにより、車速を設定車速に維持する拡大定速走行制御を実行する。車両運転支援装置は、拡大定速走行制御の実行時、設定車速が所定車速以下である場合、設定車速が所定車速よりも高いときに比べ、拡大車速制御範囲の下限値と設定車速との差が小さくなるように拡大車速制御範囲の下限値を設定し、或いは、駆動装置を最適エネルギー効率で作動させたときの駆動力よりも小さい駆動力により自車両を加速する。【選択図】 図16
