To reduce an amount of map data provided for traveling support of a vehicle.SOLUTION: In a vehicle travel support method, map data including respective information on the position and shape of lanes (L1-L4) is read, and the present self-position of the own vehicle 1 on the map data is acquired. Based on the map data and the self-position, a lane (L1, L3, L4) in which the own vehicle is likely to travel in the future is selected as an object lane among lanes within a predetermined distance ahead of the traveling direction of the own vehicle 1 from the self-position, and only the map data of the object lane is extracted from the map data. The traveling of the own vehicle 1 is supported based on the extracted map data.SELECTED DRAWING: Figure 3A

    【課題】車両の走行支援のために提供される地図データのデータ量を軽減する。【解決手段】車両走行支援方法では、車線(L1〜L4)の位置及び形状の情報を車線毎に含んだ地図データを読み込み、地図データ上の現在の自車両1の自己位置を取得し、地図データと自己位置とに基づいて、自己位置から自車両1の進行方向前方の所定距離以内の車線のうち、自車両が将来走行する可能性が高い車線(L1、L3、L4)を、対象車線として選択し、地図データのうち、対象車線の地図データのみを抽出し、抽出された地図データに基づいて自車両1の走行を支援する。【選択図】図3A
