Zusammenfassung: | PROBLEM TO BE SOLVED: To execute a lane deviation suppression in accordance with the state of a lane.SOLUTION: A lane deviation suppression apparatus includes: lane state detection means for detecting a state of a lane: determination means for determining whether a vehicle deviates from a travel lane on the basis of the state of the lane detected by the lane state detection means, a reference line generated toward a lane center side than a division line of the lane in accordance with the state of the lane and an estimated position of the vehicle after a given period of time; computation means for setting a variable for determining a steering amount in accordance with a deviation amount of deviating the lane in the case of the determination means determining that the vehicle deviates the travel lane, and computing a steering amount on the basis of the set variable and a target steering amount relative to the reference line; and suppression means for suppressing the vehicle from moving in a turning direction on the basis of the steering amount computed by the computation means.SELECTED DRAWING: Figure 4
【課題】車線の状態に応じて車線逸脱抑制を実行すること。【解決手段】車線逸脱抑制装置は、車線の状態を検出する車線状態検出手段と、前記車線検出手段により検出した前記車線の状態と、前記車線の状態に応じて前記車線の区画線より車線中央側に作成される基準線と、前記車両の所定時間後の推定位置とに基づいて、前記車両が走行車線を逸脱するか否かを判定する判定手段と、前記判定手段により前記車両が前記走行車線を逸脱すると判定された場合、前記車線を逸脱する逸脱量に応じて操舵量を決定するための変数を設定し、この設定した変数と、前記基準線に対する目標操角とに基づいて操舵量を演算する演算手段と、前記演算手段により演算した操舵量に基づいて前記車両の旋回方向の移動を抑制する抑制手段と、を備える。【選択図】図4 |
