Description
すなわち、クラッチの表面温度と深部温度の差が、現在設定されているT−S曲線をそのまま使用する場合に問題を引き起こすレベルの場合には、このような温度差を考慮して前記曲線補正段階(S40)を介してT−S曲線を補正するようにすることにより、より適切なクラッチの制御によりクラッチの耐久性を向上させるとともに、衝撃を防止することができるようにした。
S20 クラッチ判断段階
S30 表面温度判断段階
S40 曲線補正段階
S40−1 プラス補正段階
S40−2 マイナス補正段階
Claims (2)
- 駆動側クラッチの表面温度と深部温度との差が所定の基準値を超えるか否かを判断する温度差判断段階と、
前記温度差判断段階の遂行結果、温度差が前記基準値を超える場合には、トルク-ストローク曲線としてのT−S曲線を補正する曲線補正段階と、を含み、
前記曲線補正段階では、現在選択されているT−S曲線の位置から、より温度が高くなるにつれて曲線が移動する方向にT−S曲線を移動させて補正することを特徴とする、車両のクラッチ特性補正方法。 - 前記駆動側クラッチが、DCTを構成するクラッチ1とクラッチ2からなり、
前記クラッチ1は、特定の温度を基準として、前記特定の温度以下では昇温するにつれて同一の伝達トルクに対してアクチュエータのストロークが増加する方向にトルク-ストローク曲線としてのT−S曲線が移動する属性を有し、前記特定の温度超過では昇温するにつれて同一の伝達トルクに対してストロークが減少する方向にトルク-ストローク曲線としてのT−S曲線が移動する属性を有し、
前記クラッチ2が、昇温するにつれて同一の伝達トルクに対してアクチュエータのストロークが減少する方向にトルク-ストローク曲線としてのT−S曲線が移動する属性を有する場合、
前記温度差判断段階の遂行結果、温度差が前記基準値を超過したならば、現在変速段の連結されたクラッチがクラッチ1およびクラッチ2のいずれであるかを判断するクラッチ判断段階を、さらに含み、
前記クラッチ判断段階の遂行結果、現在変速段の連結された駆動側クラッチがクラッチ1である場合、前記曲線補正段階は、
クラッチの表面温度が前記特定の温度以下であるか否かを判断する表面温度判断段階を含み、
さらに、前記表面温度判断段階の遂行結果、表面温度が前記特定の温度以下である場合にはT−S曲線をストロークが増加する方向に移動させてプラス補正し、前記表面温度判断段階の遂行結果、表面温度が前記特定の温度を超える場合にはT−S曲線をストロークが減少する方向に移動させてマイナス補正し、
