To provide a technology capable of early or further reliably detecting a vehicle in a reverse driving.SOLUTION: A reverse driving determination method of a vehicle includes the steps of acquiring front images and rear images of a vehicle, recognizing surrounding targets of the vehicle using the front images and the rear images, calculating reverse driving likelihood based on the recognized information of the targets, and determining that the vehicle drives reversely when the reverse driving likelihood exceeds a threshold. A high value is used for the calculation factor of the reversing driving likelihood as compared with otherwise when in the calculating step of the reverse driving likelihood, recognition information of s guiding display surface on traffic control signs is included in the recognition information of the targets using the rear images.SELECTED DRAWING: Figure 8
【課題】車両の逆走をより早期に又はより確実に検出することが可能な技術を提供する。【解決手段】車両の逆走を判定する方法は、車両の前方及び後方画像を取得するステップと、前記前方及び後方画像を用いて前記車両の周囲の物標を認識するステップと、前記物標の認識情報に基づいて、逆走尤度を計算するステップと、前記逆走尤度が閾値以上の場合、前記車両が逆走していると判定するステップと、を含む。前記逆走尤度の計算ステップでは、前記後方画像を用いた前記物標の認識情報に交通標識の案内表示面の認識情報が含まれる場合、そうでない場合に比べて前記逆走尤度の計算因子に高い値が用いられる。【選択図】図8
