PROBLEM TO BE SOLVED: To improve accuracy for detecting the passing of another vehicle on the lateral side of the own vehicle.SOLUTION: A radar system 4 detects an observation point length L and an observation point azimuth θ. Furthermore, the radar system 4 calculates an observation point lateral position x and an observation point longitudinal point y on the basis of the observation point length L and the observation point azimuth θ. Moreover, the radar system 4 determines the detection of a running vehicle if the number of observation points within a lateral determination range set to contain a preset passing determination line to extend along a direction of 90° with respect to a vehicle front-rear direction on a lateral side of a vehicle on the basis of the observation point lateral position x and the observation point longitudinal position y is equal to or greater than a preset vehicle presence determination number.SELECTED DRAWING: Figure 1

    【課題】自車両の側方における他車両の通過を検出する精度を向上させる【解決手段】レーダ装置4は、観測点距離Lと観測点方位θとを検出する。またレーダ装置4は、観測点距離Lと観測点方位θに基づいて、観測点横位置xと観測点縦位置yを算出する。さらにレーダ装置4は、観測点横位置xと観測点縦位置yに基づいて、車両の側方において車両の前後方向に対して90?の方向に沿って延びるように予め設定された追越判定ラインを含むように設定された側方判定範囲内に含まれる観測点の数が、予め設定された車両存在判定数以上である場合に、走行車両を検出したと判断する。【選択図】図1
