PROBLEM TO BE SOLVED: To reduce unnecessary warning operations.SOLUTION: In the case where the following vehicle is detected (S22: Yes), a rear warning ECU 10 determines that the following vehicle is in a passing operation of the own vehicle when following three conditions are satisfied: acceleration G1 in a longitudinal direction of the following vehicle is equal to or greater than a passing determination threshold G1ref (S24: Yes); acceleration G2 in a transverse direction of the following vehicle is equal to or greater than a passing determination threshold G2ref (S25: Yes); and an offset D being a distance where the following vehicle is deviated in a vehicle width direction of the own vehicle, is equal to or greater than a passing determination threshold Dref (S26: Yes). In the case where a determination is made that the following vehicle is in the passing operation of the own vehicle, the rear warning ECU 10 does not issue warning even when the following vehicle approaches the own vehicle.SELECTED DRAWING: Figure 6
【課題】 不要な警報作動を低減する。【解決手段】 後方警報ECU10は、後続車両が検出されている場合(S22:Yes)、後続車両の前後方向の加速度G1が追い越し判定閾値G1ref以上であり(S24:Yes)、後続車両の横方向の加速度G2が追い越し判定閾値G2ref以上であり(S25:Yes)、後続車両が自車両の車幅方向にずれている距離であるオフセットDが追い越し判定閾値Dref以上である(S26:Yes)という3つの条件が成立した場合に、後続車両が自車両を追い越しする追い越し動作中であると判定する。後方警報ECU10は、後続車両が追い越し動作中であると判定している場合には、後続車両が接近しても警報を発しない。【選択図】 図6
