To obtain a driving support device of motor cycle, capable of accurately outputting approach warning of another vehicle during traveling on a curve.SOLUTION: A driving support device 10 of a motor cycle includes: a curve traveling determination section 11 for determining whether an own vehicle is traveling on a curve based on a lean angle θ of the own vehicle; a curvature radius calculation section 12 for calculating a curvature radius R of a curve based on an own vehicle speed V and a lean angle θ when it is determined that the own vehicle is traveling on a curve; an other vehicle lane estimation section 13 for estimating a traveling lane of another vehicle by comparing a distance between the other vehicle being an approach determination object and a center of curvature of a curve with the curvature radius R; and a warning determination section 141 for determining necessity of an output of approach warning based on a distance D between the own vehicle and the other vehicle, a relative speed U of the other vehicle with respect to the own vehicle, and relation between a traveling lane of the own vehicle and a traveling lane of the other vehicle.SELECTED DRAWING: Figure 1

    【課題】カーブ走行中における他車両の接近警告をより的確に出力させることができる自動二輪車の運転支援装置を得ることを目的とする。【解決手段】自動二輪車の運転支援装置10は、自車両のリーン角θに基づいて、自車両がカーブを走行中であるか否かを判定するカーブ走行判定部11と、自車両がカーブを走行中であると判定された場合に、自車両車速Vとリーン角θに基づいて、カーブの曲率半径Rを演算する曲率半径演算部12と、接近判定の対象の他車両とカーブの曲率中心との間の距離と曲率半径Rとを比較して、他車両の走行車線を推定する他車両車線推定部13と、自車両と他車両との間の距離D、自車両に対する他車両の相対速度U、および自車両の走行車線と他車両の走行車線との関係に基づいて接近警告の出力の要否を判定する警告判定部141とを備えた。【選択図】図1
