Title:
クラッチ特性曲線の補正をするための方法
Document Type and Number:
Japanese Patent JP4500800
Kind Code:
B2
Abstract:
The invention relates to a method for adapting the characteristic curve of a clutch of an automatic twin-clutch transmission, particularly in a motor vehicle, during operation of the engine. Said method comprises the following steps: a) a manipulated coupling variable having a defined value is generated on a clutch (K1; K2) associated with a free transmission input shaft (W1; W2); b) waiting until the rotational speed (nfW) of the free transmission input shaft (W1; W2) is identical to the engine speed (nMot); c) a synchronizing device (S1-S4) associated with a gear (G1-G6) of the free transmission input shaft (W1; W2) is actuated, a value of a manipulated synchronization variable increasing in accordance with an increasing synchronizing force; d) the value of the manipulated synchronization variable, at which the rotational speed (nfW) of the free transmission input shaft (W1; W2) diverges from the engine speed (nMot), is determined; e) the determined value of the manipulated synchronization variable is assigned to the defined value of the manipulated coupling variable. A clutch torque corresponding to a synchronizing torque that corresponds to the determined value of the manipulated synchronization variable is assigned to the defined value of the manipulated coupling variable.
