Problems solved by technology

[0008] However, while the vehicle is moving, the T-S curve changes due to various reasons, such as the deterioration and expansion of the pad, the thermal deformation of the cover, the wear of the pad lining, and the change of the coefficient of friction, so the process of learning the contact point Errors may occur in
[0009] Therefore, if the learned value of the clutch contact point is greater than the position of the actual contact point, a clutch actuator stroke greater than the actual contact point is applied, so that shock due to clutch engagement may occur when clutch torque is applied

Abstract

A method for preventing burst of a clutch for a vehicle. The present disclosure relates to a technique of suppressing the occurrence of an impact caused by clutch engagement by differently controllinga clutch depending on whether or not a brake is in operation. Disclosed is a method of controlling a clutch for a vehicle, which effectively reduces engagement impact that occurs when the clutch is engaged by performing control such that a rising slope of clutch torque up to a touch point is gentler when the brake is not in operation than when the brake is in operation.

Description

technical field [0001] The present invention relates to a method of controlling a clutch for a vehicle, by which the clutch is controlled differently depending on whether a brake is being operated, thereby suppressing the occurrence of a shock caused by clutch engagement. Background technique [0002] The descriptions in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] A typical automatic transmission system has a launch / shift advantage because the torque converter acts as a fluid clutch, thereby obtaining a damping effect. [0004] On the other hand, an automated manual transmission (AMT) system and a dual clutch transmission (DCT) system have high fuel efficiency because clutches are automatically controlled based on a manual transmission mechanism without using a torque converter. [0005] However, the automatic manual transmission system directly connects an engine and a clutch thereby improv...
