PROBLEM TO BE SOLVED: To provide a white line follow-up travel controller which can cope with anxiety when a user guides a vehicle by recognizing left and right white lines, and when any one of the white lines becomes unrecognisable, a user continues to guide the vehicle based on the other white line and width between both white lines which has been recognized, and a probability that a road width may become narrower actually.SOLUTION: When any one of left and right white lines becomes unrecognisable, the vehicle is guided along a position which is apart by a distance smaller than a half length of width W between the white lines which has been calculated based on recognition of left and right both white lines, by a predetermined shift amount S from the white line which can be recognized toward the side on which the white line becomes unrecognisable.SELECTED DRAWING: Figure 2
【課題】左右の白線を認識して車輌を誘導していたとき、左右いずれか一方の白線が認識されなくなったとき、単に残る片側の白線とそれまで認識されていた両白線間の幅にそのままに基づいて車輌の誘導を続ける際の一抹の不安と、実際に道幅も多少は狭まる虞れに対処する白線追従走行制御装置を提供する。【解決手段】左右いずれか一方の白線が認識されなくなったとき、認識されている側の白線より、白線が認識されなくなった側へ向けて、それまでに左右の白線の認識に基づいて算出されていた両白線間の幅Wの半分より所定のシフト量Sだけ小さい距離隔たった位置に沿って、車輌を誘導する。【選択図】図2
