PROBLEM TO BE SOLVED: To provide a traffic lane departure alarm device which enables reduction in botheration felt by a driver.SOLUTION: A traffic lane departure alarm device 100 includes: an alarm setting part 23 for setting an alarm signal to a first alarm signal when it is determined that a direction indicator 1 is operated by an indication state determination part 22, and setting the alarm signal to a second alarm signal notifying a driver of a danger when it is determined that the operation of the direction indicator 1 is stopped by the indication state determination part 22; a departure determination part 24 for determining that an own vehicle is apt to deviate a lane when the own vehicle is within a range of the predetermined distance from a boundary line; and a notifying part 31 for issuing the alarm signal set by an alarm setting part 23 based on a determination result of the departure determination part 24. The alarm setting part 23, when the alarm signal is set to the first alarm signal, maintains the setting of the alarm signal even when a determination result of the indication state determination part 22 is changed.SELECTED DRAWING: Figure 1
【課題】運転者が感じる煩わしさを低減する車線逸脱警報装置を提供する。【解決手段】車線逸脱警報装置100は、指示状態判定部22によって方向指示器1が作動していると判定された場合には、警報信号を第一警報信号に設定し、指示状態判定部22によって方向指示器1の作動が停止していると判定された場合には、警報信号を運転者に危険を知らせる第二警報信号に設定する警報設定部23と、自車両が車線の境界線から所定距離の範囲内にある場合には自車両が逸脱傾向にあると判定する逸脱判定部24と、逸脱判定部24の判定結果に基づいて、警報設定部23が設定した警報信号を発報する報知部31と、を備え、警報設定部23は、警報信号が第一警報信号に設定される場合において、自車両が逸脱傾向中である間は、指示状態判定部22の判定結果が変化しても警報信号の設定を維持する。【選択図】図1
