PROBLEM TO BE SOLVED: To provide a method for determining detection, by providing a quantitative evaluation value of stability of a vehicle.SOLUTION: This method uses a vehicle motion state quantity of expressing lateral motion of a vehicle, a physical quantity S generated by steering wheel operation of the vehicle, a time variation V of the vehicle motion state quantity and a time variation Y of the physical quantity generated by the steering wheel operation. When assuming a case of being wholly the same sign (a plus or a minus) in a vehicle motion state quantity of expressing the lateral motion of the vehicle measured in gentle acceleration turning time in one direction, the physical quantity S generated by the steering wheel operation of the vehicle, the time variation V of the vehicle motion state quantity and the time variation Y of the physical quantity generated by the steering wheel operation, when the vehicle motion state quantity and the physical quantity generated by the steering wheel operation are a different sign and when the time variation of the vehicle motion state quantity and the time variation of the physical quantity generated by the steering wheel operation are also a different sign, it is determined as instability.SELECTED DRAWING: Figure 3
【課題】車両の安定性の定量的な評価値を得、検出判断する方法を提供する。【解決手段】車両の横運動を表す車両運動状態量、と車両のハンドル操作により生じる物理量S、車両運動状態量の時間変化量V、ハンドル操作により生じる物理量の時間変化量Yを用いる。一方向への緩加速旋回時に計測される、車両の横運動を表す車両運動状態量、と車両のハンドル操作により生じる物理量S、車両運動状態量の時間変化量V、ハンドル操作により生じる物理量の時間変化量Yが全て同符号(プラスまたはマイナス)の場合を仮定すると、車両運動状態量とハンドル操作により生じる物理量が異符号でかつ、車両運動状態量の時間変化量とハンドル操作により生じる物理量の時間変化量が異符号の場合に不安定と判断する。【選択図】図3
