To provide a driving assistance system for a motorcycle capable of performing notification of deviation from a travel line of an own vehicle at appropriate timing corresponding to an attitude of a traveling vehicle body.SOLUTION: A driving assistance system 1 includes: a division line position acquisition part for acquiring an object division line position PL0 of an object division line on the basis of front information on a front state of an own vehicle 7; and a deviation notification part for performing notification on deviation of the own vehicle 7 from a travel line 9 on the basis of a relation between the object division line position and set positions P1, P2 which are set in the own vehicle 7. When it is not grasped that the own vehicle is curve-traveling or leaning, the deviation notification part performs notification on the basis of a positional relation between the object division line position PL0 and the first set position P1 determined on a front tire 71 of the own vehicle 7. Otherwise, when it is grasped that the own vehicle is curve-traveling or leaning, the deviation notification part performs notification on the basis of a relation between the object division line position PL0 and a second set position P2 determined on a vertically upper side of the first set position P1 of the own vehicle 7.SELECTED DRAWING: Figure 8

    【課題】走行中の車体の姿勢に応じた適切なタイミングで自車の走行車線からの逸脱に関する通知を行うことができる自動二輪車の運転支援システムを提供すること。【解決手段】運転支援システム1は、自車7の前方の状態に関する前方情報に基づいて対象区画線の対象区画線位置PL0を取得する区画線位置取得部と、対象区画線位置と自車7に定められた設定位置P1,P2との関係に基づいて自車7の走行車線9からの逸脱に関する通知を行う逸脱通知部と、を備える。逸脱通知部は、カーブ走行中又は傾斜中であると把握されていない場合、対象区画線位置PL0と自車7の前タイヤ71に定められた第1設定位置P1との位置関係に基づいて通知を行い、カーブ走行中又は傾斜中であると把握されている場合、対象区画線位置PL0と自車7のうち第1設定位置P1よりも鉛直方向上方側に定められた第2設定位置P2との関係に基づいて通知を行う。【選択図】図8
