Description
1)車速が速いことにより周囲の雑音などでショックを感じないようにできるため。
2)CVT3の変速比が最ハイ(最High)場合、車体側に伝わるクラッチ締結時のショックが、CVT3の変速比が最ロー(最Low)のときの1/4程度となり、大幅に低減されるため。
3)超高速(例えば時速100km/h)では、CVT入力軸3aの回転数を上昇させるためにクラッチ締結時に急速な追従性が必要となるため。
ステップS11にてタイマーが始動してからトルク解放時間ttrqが経過していないと判定されると、ステップS10へ進む。
Claims (4)
- クラッチを介して車両の駆動輪に駆動力を伝達する内燃機関の制御方法において、
上記クラッチが開放された状態で自動停止している上記内燃機関を再始動するにあたって、
上記内燃機関の再始動後に上記クラッチを締結して車両を加速する際に上記内燃機関の目標トルクを低下させるトルクダウン制御を実施するとともに、上記トルクダウン制御における目標トルクを上記トルクダウン制御中の車速とアクセル開度に応じて決まる所定のトルク下限値に設定し、
上記トルク下限値は、車速が速いほど大きくなり、アクセル開度が大きいほど大きくなるよう設定され、アクセル開度が全開のときに所定の全開所定値に、アクセル開度が全閉のときに所定の全閉所定値に設定される内燃機関の制御方法。 - 車両の走行抵抗及び車両のパワートレインの抵抗を補填できるように上記トルク下限値を設定する請求項1に記載の内燃機関の制御方法。

- 車両の駆動輪に駆動力を伝達する内燃機関と、
上記内燃機関と上記駆動輪との間に配置されたクラッチと、
上記クラッチが開放された状態で自動停止している上記内燃機関の再始動後に上記クラッチを締結して車両を加速する際に上記内燃機関の目標トルクを低下させて所定のトルク下限値に設定するトルクダウン制御を実施するトルクダウン制御部と、
上記トルクダウン制御中の車速とアクセル開度に応じて決まる上記トルク下限値を算出するトルク下限値算出部と、を有し、
上記トルク下限値算出部は、車速が速いほど大きくなり、アクセル開度が大きいほど大きくなるよう上記トルク下限値を算出するとともに、アクセル開度が全開のときに所定の全開所定値を、アクセル開度が全閉のときに所定の全閉所定値を、上記トルク下限値として算出する内燃機関の制御装置。
