Torque-stroke learning method of clutch

Abstract

Provided is a torque-stroke learning method of a clutch. During a process of dividing a torque region on a torque-stroke curve (T-S curve) of a clutch into two or more regions and learning the T-S curve passing through two or more torque regions with different torque section values, by learning the curve for any torque region (a high-torque region or a low-torque region) when the curve is learnedfor other torque regions with guaranteed reliability, it is possible to prevent a problem of the T-S curve not converging to a previously learned curve value when the T-S curve is continuously learnedfor the two or more different torque regions. When the torque region is divided into two or more regions such as a low-torque region and a high-torque region and the T-S curve is learned for any region, the T-S curve is learned for another region on the basis of reliable data obtained for the other region such that the mutually connecting curves converge to each other. Thus, it is possible to accurately learn the T-S curve, thus preventing a slip or a shift shock.

Description

technical field [0001] The present invention relates to a torque-stroke learning method for a clutch, and in more detail, involves dividing the torque region on the clutch T-S curve into two or more regions. During the learning process of the T-S curve (torque-stroke curve) in the torque area, when learning the curve of any torque area (assuming high torque area or low torque area), at the same time, other The learning of the torque range can prevent the torque-stroke learning method of the clutch from the problem of non-convergence with the learned curve value when the T-S curve learning is continuously performed between two or more different torque ranges. Background technique [0002] In general, in a transmission that transmits power from an engine, a clutch that is one of the transmission components plays a role in transmitting power by contacting a drive shaft engaged with a gear with the engine, or separating the drive shaft from the engine. . [0003] The engine is...

Problems solved by technology

[0010] According to such a method, there is a possibility that when curve learning is performed in the direction from the high torque area to the low torque area, the T-S curve that has been performed in the low torque area is distorted and the learning points do not match, thereby connecting different torques The problem that the curves of the T-S curves of the regions between each other do not converge, and the same problem exists in the opposite case
