PROBLEM TO BE SOLVED: To achieve simple and early determination of a deviation of a vehicle from a lane being a driver's unintended deviation.SOLUTION: A lane deviation determination unit 12 determines whether or not a vehicle is under a first lane deviation state in which part of a vehicle 5 (for example, a tire of the vehicle 5) is beyond inner edges 9 of right and left white lines 7 outward, on the basis of left and right white line inner edge positions Pand Pinput from a lateral position calculation unit 11. A lateral speed calculation unit 13 calculates a lateral speed Vwhich is a traveling speed of the vehicle 5 in the vehicle width direction of a lane 6 by time-differentiating the left and right white line inner edge positions Pand Prepeatedly input from the lateral position calculation unit 11. A deviation mode determination unit 14 determines it to be a driver's unintended lane deviation if a magnitude of the lateral speed Vof the vehicle 5 input from the lateral speed calculation unit 13 is less than a predetermined threshold value Vand is under the first lane deviation state.SELECTED DRAWING: Figure 1

    【課題】車線からの車両の逸脱が運転者の意図しない逸脱であるとの判定を簡易に且つ早期に行う。【解決手段】車線逸脱判定部12は、車両5の一部(例えば車両5のタイヤ)が左右の白線7の内側縁9を外側へ越えた第1車線逸脱状態であるか否かを、横位置演算部11から入力した左右の白線内縁位置PLL1,PLR1に基づいて判定する。横速度演算部13は、横位置演算部11から繰り返して入力する左右の白線内縁位置PLL1,PLR1を時間微分することによって、車線6の車線幅方向への車両5の移動速度である横速度VLを演算する。逸脱態様判定部14は、横速度演算部13から入力した車両5の横速度VLの大きさが予め設定された閾値VL1未満であり、且つ第1車線逸脱状態であるとき、運転者の意図しない車線逸脱であると判定する。【選択図】図1
