REVERSE RUN PREVENTING APPARATUS AND REVERSE RUN PREVENTING METHOD

To suppress an unnecessary warning by reverse run determination.SOLUTION: A reverse run preventing apparatus comprises: a reverse run determination unit that determines whether or not a self-vehicle is driving in a wrong way; a warning unit that warns a driver of the self vehicle when the reverse run determination unit determines that the self-vehicle is driving in a wrong way; an inter-vehicle distance detection unit that detects a distance between the self-vehicle and a vehicle present ahead of the self-vehicle; a passing sign detection unit that detects a passing sign as a sign that the self-vehicle is about to overtake the vehicle ahead by straying onto an opposing lane on the basis of at least one of a behavior of the self-vehicle and a behavior of the driver when the distance detected by the inter-vehicle distance detection unit is a predetermined distance or less; a lane type detection unit that detects a lane type of a center line; and a warning suppression unit that suppresses warning when the passing sign detection unit detects the sign and the lane type of the center line detected by the lane type detection unit allows the self vehicle to stray onto the opposing lane to overtake.SELECTED DRAWING: Figure 1 【課題】逆走判定による不必要な警告を抑制することができる。【解決手段】自車両が逆走しているか否かを判定する逆走判定部と、逆走判定部が逆走していると判定した場合に、自車両の運転者の警告を行う警告部と、自車両前方に存在する車両との距離を検出する車間距離検出部と、車間距離検出部が検出した距離が予め定められた距離以下の場合に、自車両の挙動および運転者の挙動の少なくとも一方に基づいて、前方に存在する車両を対向車線にはみ出して追い抜こうとしている予兆である追抜き予兆を検出する追抜き予兆検出部と、央線の線種を検出する線種検出部と、追抜き予兆検出部が前記予兆を検出し、且つ、線種検出部が検出した中央線の線種が対応車線にはみ出して追抜き可能である場合、警告を抑止する警告抑止部と、を備える。【選択図】図１
