PROBLEM TO BE SOLVED: To provide a lane boundary monitoring method for setting a condition of indicating proximity to a lane boundary depending on the dangerousness at the time of coming into contact with a target located on the lane boundary.SOLUTION: A lane boundary monitoring method includes the steps of: radiating an output wave for distance measurement from a distance measurement sensor 22 mounted on a vehicle 80 toward the road surface around a vehicle 80 and generating a detection wave on the basis of a reflection wave (S1); detecting at least one of the height of a target 85 located on the lane boundary and the smoothness of a change in the surface height of the target 85 on the basis of the spacial change of the detection wave (S3, S4); and setting a distance threshold value for determining whether or not proximity to the lane boundary requires a caution depending on the distance between the vehicle 80 and the lane boundary, according to the at least one od the height and the smoothness (S5).SELECTED DRAWING: Figure 9
【課題】走路境界への接近を知らせる条件を、走路境界にある物標との接触時の危険性に応じて設定する。【解決手段】走路境界監視方法では、車両80に搭載した測距センサ22から車両80の周囲の路面へ向けて距離測定用の出力波を照射し、その反射波に基づき検知波を生成し(S1)、検知波の空間的変化に基づいて、走路境界にある物標85の高さ又は物標85の表面の高さ変化のなだらかさの少なくとも一方を検出し(S3、S4)、車両80と走路境界との間の距離に応じて走路境界への接近を警戒すべきか否かを判定するための距離閾値を、高さ又はなだらかさの少なくとも一方に応じて設定する(S5)。【選択図】図9
