VEHICLE DRIVING SUPPORT DEVICE, VEHICLE DRIVING SUPPORT METHOD, AND PROGRAM

To provide a vehicle driving support device which prevents or suppresses automatic deceleration control from being terminated at a time not intended by a driver.SOLUTION: A driving support ECU 21 of a driving support device 11a executes automatic deceleration control to decelerate a vehicle 10 independent of a driver's operation of a brake pedal 105 when it is determined that a special condition representing that the driver intends to turn the vehicle 10 right or left at an intersection located ahead of the vehicle 10 is established. If operations of turn indicators 34, 35 are stopped while the automatic deceleration control is executed, the automatic deceleration control is continued until a predetermined time elapses after the operations of the turn indicators 34, 35 are stopped, and if the turn indicators 34, 35 are not activated until the predetermined time elapses after the operations of the turn indicators 34, 35 are stopped, the automatic deceleration control is terminated.SELECTED DRAWING: Figure 2 【課題】運転者の意図しない時点で自動減速制御が終了することを防止または抑制する車両の運転支援装置を提供する。【解決手段】運転支援装置１１ａの運転支援ＥＣＵ２１は、運転者が車両１０の前方に存在する交差点において車両１０を右折または左折させる意思を有していることを示す特定条件が成立したと判定した場合、運転者のブレーキペダル１０５の操作によらずに車両１０を減速させる自動減速制御を実行し、自動減速制御の実行中に方向指示器３４，３５の動作が停止した場合、方向指示器３４，３５の動作が停止した時点から所定時間が経過するまで前記自動減速制御を継続し、方向指示器３４，３５の動作が停止してから所定時間が経過するまで方向指示器３４，３５が動作しなかった場合、自動減速制御を終了する。【選択図】図２
