PROBLEM TO BE SOLVED: To provide a traffic lane deviation warning device and a traffic lane deviation warning method capable of preventing emission of undesired alarm of traffic lane deviation.SOLUTION: The traffic lane deviation warning device in an embodiment includes a deviation detection part, a deviation amount monitoring part and a warning part. The deviation detection part detects a deviation of own vehicle from a traveling traffic lane. When the deviation detection part detects a deviation, the deviation amount monitoring part monitors the deviation amount of the position of own vehicle with respect to a segmentation line of the traveling traffic lane. In the case of at least either one of when the deviation amount monitoring part determines that the deviation amount exceeds a first threshold level, or when the deviation amount monitoring part determines that the deviation amount per unit time exceeds a second threshold level, the warning part emits a warning.SELECTED DRAWING: Figure 1
【課題】不必要に車線逸脱の警告を行うことを抑制することができる車線逸脱警告装置および車線逸脱警告方法を提供すること。【解決手段】実施形態に係る車線逸脱警告装置は、逸脱検知部と、変動量監視部と、警告部とを備える。逸脱検知部は、自車両の走行車線からの逸脱を検知する。変動量監視部は、逸脱検知部によって逸脱が検知された場合に、走行車線の区画線に対する自車両位置の変動量を監視する。警告部は、変動量監視部によって変動量が第1閾値を超えたと判定される場合、および単位時間あたりの変動量が第2閾値を超えたと判定される場合のうち、少なくともいずれか一方の場合に、警告を行う。【選択図】図1
