A method for adaptive clutch learning of critical clutch characteristics includes decreasing pressure supplied to a clutch until clutch slip occurs to obtain a plurality of clutch slip adapt points, each clutch slip adapt point including a clutch slip pressure value and a corresponding clutch slip torque value. If a maximum of the plurality of clutch slip adapt points obtained determined to be greater than maximum adapt point limits then the maximum and a minimum of the plurality of clutch slip adapt points are removed. The method ends with determining a best fit line based on the plurality ofclutch slip adapt points when a predetermined number of clutch slip adapt points are obtained. 种用于临界离合器特性的自适应离合器学习的方法包括减小供应到离合器的压力直到发生离合器滑移以获得多个离合器滑移适应点，每个离合器滑移适应点包括离合器滑移压力值和对应的离合器滑移转矩值。如果所获得的多个离合器滑移适应点中的最大值被确定为大于最大适应点极限，则除去多个离合器滑移适应点中的最大值和最小值。该方法结束于当获得预定数量的离合器滑移适应点时基于多个离合器滑移适应点确定最佳拟合线。
