Claims (1)
- 少なくともエンジン負荷および車速に基づいて車両の予想加速度を算出する予想加速度算出手段(M1)と、
車両の実加速度を算出する実加速度算出手段(M2)と、
前記予想加速度および前記実加速度の差に基づいて車両が登坂路を走行しているか否かを判定する指標となる登坂判定値(PNO)を算出する登坂路判定手段(M3)と、
少なくとも登坂路走行用および平坦路走行用の変速特性を含む複数の変速特性の何れかを選択する変速特性選択手段(M4)と、
前記変速特性選択手段(M4)により選択した変速特性に基づいて変速を行う変速制御手段(M5)と、
を備える車両用変速制御装置において、
前記登坂路判定手段(M3)は、なまし係数(KA,KB)を用いて前記登坂判定値(PNO)をなまし計算することで登坂判定補正値(PNOAVE)を算出するとともに、その算出された前記登坂判定補正値(PNOAVE)の前回値が予め定められた閾値以上である場合には、前記閾値未満である場合よりも前記登坂判定補正値(PNOAVE)の前回値に対する今回値の変化率が小さくなるように前記なまし係数(KA,KB)を更新し、前記変速特性選択手段(M4)は、前記登坂判定補正値(PNOAVE)に基づいて前記複数の変速特性の何れかを選択することを特徴とする車両用変速制御装置。
