To accurately set a center position of a marker when a tow vehicle and a towed vehicle are connected to travel straight regardless of a marker attachment position of the towed vehicle.SOLUTION: A towing support device obtains a knuckle θ between a tow vehicle 100 and a towed vehicle 200 and presents knuckle information to a driver. The device includes an on-vehicle camera 10, a marker center search section 31, an offset correction value estimation processing section 32, a rotation axis position estimation processing section 33, and a knuckle calculation section 36. The offset correction value estimation processing section 32 stores center positions of a marker 220 during straight traveling of the tow vehicle 100 and the towed vehicle 200, determines a convergence value of the stored center positions of the marker 220, and allows the determined convergence value to be set as an offset correction value.SELECTED DRAWING: Figure 1

    【課題】被牽引車のマーカー取り付け位置にかかわらず、牽引車と被牽引車が連結して直進しているときのマーカーの中心位置を精度良く設定すること。【解決手段】牽引車100と被牽引車200とがなす折れ角θを求め、折れ角情報をドライバーに提示する牽引支援装置であって、車載カメラ10と、マーカー中心探索部31と、オフセット補正値推定処理部32と、回転軸位置推定処理部33と、折れ角演算部36と、を備える。オフセット補正値推定処理部32は、牽引車100と被牽引車200が直進走行しているときのマーカー220の中心位置を蓄積し、蓄積したマーカー220の中心位置の収束値を求め、求めた収束値をオフセット補正値に設定する。【選択図】図1
