To realize a technique capable of reducing a ratio that a reverse drive warning becomes an unnecessary warning for a driver when the reverse drive warning is issued to an objective vehicle which enters, while rotating, an approach road having an opposite lane from a crossing.SOLUTION: A reverse drive warning system 1 comprises: an approach lane presumption unit 14 for presuming an approach lane in an approach road on the basis of travel track information, relative relationship information and lane information; a warning processing unit 15 which issues a reverse drive warning in a case where the presumed approach lane is an opposite lane; and a reverse drive factor determination unit 16 for determining a reverse drive factor indicating a factor causing the approach lane to be assumed to be the opposite lane. In a case where the determined reverse drive factor is a specific factor that has been previously specified, the warning processing unit 15 limits the reverse drive warning.SELECTED DRAWING: Figure 1
【課題】交差点から対向車線を有する進入道路に旋回を伴い進入する対象車両に対して逆走警告を発する場合に、逆走警告が運転者にとって不要な警告となる割合を低減することが可能な技術を実現する。【解決手段】逆走警告システム1は、走行軌跡情報及び相対関係情報と車線情報とに基づいて進入道路における進入車線を推定する進入車線推定部14と、推定された進入車線が対向車線である場合に逆走警告を発する警告処理部15と、推定された進入車線が対向車線である場合に、進入車線が対向車線である要因を示す逆走要因を判定する逆走要因判定部16と、を備える。警告処理部15は、判定された逆走要因が予め規定された規定要因である場合には、逆走警告を制限する。【選択図】図1
