学习用于双离合器变速器的离合器的离合器吻合点的方法
摘要：
一种学习双离合器变速器的第一离合器的吻合点的方法，包括将输入轴的旋转速度控制为处于预定范围内。当第一离合器和第二离合器二者被确定为从输入轴脱开，且输入轴的旋转速度处于预定范围内时，则第一离合器从脱开位置移动至接合位置。联接至第一离合器的第一变速器轴的旋转速度的增加被检测。当第一变速器轴的旋转速度的增加被检测到时，第一离合器的位置被识别。第一离合器的被识别位置作为被学习的第一离合器吻合点被存储在变速器控制模块的存储器中。
摘要（英）：

A method of learning a kiss point of a first clutch of a dual clutch transmission includes controlling a rotational speed of the input shaft to be within a pre-determined range. When both the first clutch and the second clutch are determined to be disengaged from the input shaft, and the rotational speed of the input shaft is within the pre-determined range, then the first clutch is moved from a disengaged position into an engaged position. An increase in a rotational speed of a first transmission shaft, which is coupled to the first clutch, is detected. When the increase in the rotational speed of the first transmission shaft is detected, a position of the first clutch is identified. The identified position of the first clutch is saved in a memory of a transmission control module as a learned first clutch kiss point.
