To provide a behavior determination method of a vehicle capable of determining a behavior of the vehicle without depending on a loading mode of a portable terminal on the vehicle.SOLUTION: In a behavior determination method of a vehicle, a behavior of the vehicle V is determined by using a portable terminal 10 loaded on the vehicle V. In the behavior determination method of the vehicle V, an acceleration is detected by a three-axis acceleration sensor 11 carried by the portable terminal 10, and by using a vector of the detected acceleration as a state quantity calculated in each of a plurality of kinds of frequency band, for determining the behavior of the vehicle V, an angle formed between the calculated vectors is calculated, and it is determined whether the behavior of the vehicle V is unstable or stable, based on whether the angle is larger than a threshold determined beforehand or not.SELECTED DRAWING: Figure 2

    【課題】車両に対する携帯端末の搭載態様によらずに車両の挙動を判定することができる車両の挙動判定方法を提供する。【解決手段】車両Vの挙動判定方法は、車両Vに載せられた携帯端末10を用いて車両Vの挙動を判定する。車両Vの挙動判定方法は、携帯端末10が有する3軸加速度センサ11により加速度を検出し、検出した加速度のベクトルを、複数種の周波数帯毎に算出し、車両Vの挙動を判定する状態量として、算出したベクトル同士が成す角度を算出し、角度が予め定められた閾値よりも大きいか否かに基づいて、車両Vの挙動が非安定であるか安定であるかを判定する。【選択図】図2
