To provide a vehicle driving support method and a vehicle driving support system capable of making a driver of a rear vehicle surely recognize an existence of the own vehicle intended to change a lane.SOLUTION: While a method is a vehicle driving support method for executing a lane change operation of moving the own vehicle α to an adjacent lane La2, in the vehicle driving support method, a target lane change position P2 is set; an effective field of view estimation process is executed in which an estimated effective field of view is calculated as an estimated value of an effective field of view θ that defines an effective field of view efv of a driver of a rear vehicle γ traveling behind the target lane change position; based on the estimated effective viewing angle, a standby position setting process for setting a lane change standby position P1 is executed in which the own vehicle α enters the effective field of view efv of the driver of the rear vehicle γ; the movement process to move the own vehicle α to the lane change standby position P1 is executed; a standby process is executed that causes the own vehicle α to stand by at the lane change standby position P1; and a lane change operation is executed after the standby process is completed.SELECTED DRAWING: Figure 5
【課題】車線変更動作を意図する自車両の存在を後方車両の運転者により確実に認識させることのできる車両運転支援方法及び車両運転支援システムを提供する。【解決手段】方法は、自車両αを隣接車線La2に移動させる車線変更動作を実行する車両運転支援方法であって、目標車線変更位置P2を設定し、該目標車線変更位置に後方で隣接して走行する後方車両γの運転者の有効視野efvを規定する有効視野角θの推定値として推定有効視野角演算する有効視野推定処理を実行し、推定有効視野角に基づいて自車両αが後方車両γの運転者の有効視野efv内に入る車線変更待機位置P1を設定する待機位置設定処理を実行し、自車両αを車線変更待機位置P1まで移動させる移動処理を実行し、自車両αを車線変更待機位置P1に待機させる待機処理を実行し、待機処理の完了後に車線変更動作を実行する。【選択図】図5
