PROBLEM TO BE SOLVED: To provide a rear wheel lift inclination determination device for a vehicle which can quickly determine a rear wheel lift inclination.SOLUTION: The rear wheel lift inclination determination device for a vehicle comprises: first deceleration acquisition means which acquires first deceleration along a first linear line out of acceleration applied on a center of gravity, and being a component of a first orientation; and second deceleration acquisition means which acquires second deceleration along a second linear line out of acceleration applied to a center of gravity, and being a component of a second orientation. When the first deceleration is larger than a first threshold in the first orientation, or when the second deceleration is larger than a second threshold in the second orientation, the device determines that a rear wheel is in a lift inclination, and when a second deceleration change rate being a change amount per unit time of the second deceleration becomes larger than a change rate threshold in the second orientation, the device performs at least either of setting for displacing the first threshold to a side opposite to the first orientation, and setting for displacing the second threshold to a side opposite to the second orientation.

    【課題】後輪リフト傾向の判定を迅速に行うことができる車両用後輪リフト傾向判定装置を提供する。【解決手段】重心にかかる加速度のうち第一直線に沿うと共に第一の向きの成分である第一減速度を取得する第一減速度取得手段と、重心にかかる加速度のうち第二直線に沿うと共に第二の向きの成分である第二減速度を取得する第二減速度取得手段と、を備え、第一減速度が第一閾値よりも第一の向きに大きいとき、又は第二減速度が第二閾値よりも第二の向きに大きいときに、後輪がリフト傾向にあると判定し、さらに第二減速度の単位時間当たりの変化量である第二減速度変化率が変化率閾値よりも第二の向きに大きくなるときに、第一閾値を第一の向きとは反対向きにずらす設定、及び第二閾値を第二の向きとは反対向きにずらす設定、のうち少なくとも一方の設定をする。【選択図】図1
