PROBLEM TO BE SOLVED: To provide a congestion determination device that can highly accurately determine whether an own vehicle is present in a congestion section.SOLUTION: When a speed of an own vehicle detected by an own vehicle speed detection unit 2 is equal to or less than a first prescribed speed, and a radar device 1 detects more than two preceding vehicles, inter-vehicle processing between the second preceding vehicle ahead of the two preceding vehicles and the own vehicle is equal to or less than a prescribed reference distance, and when the preceding vehicle large in a relative speed is equal to or less than a second prescribed speed, or when the inter-vehicle processing between the second preceding vehicle ahead thereof and the own vehicle is equal to or larger than the prescribed reference distance and the relative speed of the second preceding vehicle ahead thereof is smaller than that of the first preceding vehicle ahead thereof, a congestion determination unit 3 is configured to determine that the own vehicle is present in a congestion section.SELECTED DRAWING: Figure 3
【課題】自車両が渋滞区間内であるか否かを精度よく判定することができる渋滞判定装置を提供する。【解決手段】渋滞要件判定部3が、自車両速度検出部2が検出した自車両の速度が第1の所定速度以下であって、かつレーダ装置1が2台以上の先行車両を検出したとき、2台前の先行車両との車間処理が所定の基準距離以下であり、かつ相対速度が大きい方の先行車両が第2の所定速度以下である場合、あるいは、2台前の先行車両との車間距離が基準距離より大きく、かつ2台前の先行車両の相対速度が1台前の先行車両の相対速度よりも小さい場合に、自車両が渋滞区間内であると判断する。【選択図】図3
