To provide a vehicle behavior determination system and a vehicle behavior determination method, which are capable of determining whether a vehicle has executed a given specific retreating action accompanying an advancing action and a direction change action by a given angle or more within a given time period.SOLUTION: A vehicle behavior determination system includes: a shift position sensor 16 for detecting a shift position of a vehicle 11; a yaw rate sensor 18 for detecting a yaw rate of the vehicle; a rotation angle computation part for computing a rotation angle, in a plan view, of the vehicle between a start clock time and a finish clock time, on the basis of the yaw rates at the start clock time and finish clock time of a first time period; and a determination part for determining that a shift position has switched in the order of an advanceg position, a reverse position, and the advance position within the first time period, on the basis of a detection value of the shift position sensor, and determining that the vehicle has executed a specific retreating action in a case where a maximum value of an accumulation value of a rotation angle of the vehicle in one direction between the start clock time and finish clock time computed by the rotation angle computation part is equal to or higher than a threshold.SELECTED DRAWING: Figure 1
【課題】車両が所定時間内に前進動作及び所定角度以上の方向転換動作を伴う所定の特定後退動作を実行したか否かを判定可能な車両挙動判定システム及び車両挙動判定方法を提供する。【解決手段】車両11のシフトポジションを検出するシフトポジションセンサ16と、車両のヨーレートを検出するヨーレートセンサ18と、第1時間の開始時刻及び終了時刻のヨーレートに基づいて、開始時刻から終了時刻の間の車両の平面視における回転角を演算する回転角演算部と、シフトポジションセンサの検出値に基づいてシフトポジションが第1時間以内に前進位置、後進位置、前進位置の順で切り替わったと判定し、且つ、回転角演算部が演算した開始時刻から終了時刻の間の車両の一方向の回転角の累積値の最大値が閾値以上の場合に、車両が特定後退動作を実行したと判定する判定部と、を備える。【選択図】図1
