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 clutch fragmentation of a vehicle. The present invention relates to a technique for suppressing occurrence of a shock caused by clutch engagement by controlling a clutch differently depending on whether a brake is being operated. Disclosed is a method of controlling a clutch for a vehicle which is effective in reducing the clutch torque up to a contact point with a gentler slope of increase in clutch torque when the brake is not being operated than when the brake is being operated. The engagement shock that occurs when the clutch is engaged.

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 the brake is being operated, thereby suppressing the occurrence of shock caused by clutch engagement. Background technique [0002] The descriptions in this section are only intended to provide background information related to the present invention and may not constitute prior art. [0003] A typical automatic transmission system has advantages in starting / shifting because the torque converter acts as a fluid clutch, thereby obtaining a damping effect. [0004] On the other hand, the automatic manual transmission (AMT) system and the dual clutch transmission (DCT) system have high fuel efficiency because the clutch is automatically controlled based on the manual transmission mechanism without using a torque converter. [0005] However, the automatic manual transmission system directly connects the engine ...
