Problems solved by technology

[0006] In the structure of AMT, if minute slip control is performed in the same manner as DCT in order to learn the characteristic curve of clutch transmission torque, a constant load is applied to the clutch diaphragm spring and release bearing, which causes a hardware problem of the transmission, For example, the reduction in transmission durability

Embodiment Construction

[0023] The following description is merely exemplary in nature and is not intended to limit the invention, application or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0024] In some forms of the invention, a method of controlling an AMT vehicle clutch may be configured to include a first slip control step, a full lock control step, and a second slip control step.

[0025] will refer to figure 1 The present invention will be specifically described. First, at the first slip control step, when a shift to a current gear is completed while the vehicle is moving, the controller 1 may perform a slight slip control of the clutch (CL), thereby learning transmission torque characteristics of the clutch.

[0026] For example, in order to learn the transmission torque characteristic of the clutch, the clutch (CL) is controlled to slip slightly. When the transmission gear is engaged whil...

Abstract

The present application relates to a method for controlling a clutch of a vehicle having an automatic manual transmission, which relates to a technique for improving durability and shift stability of the clutch. The present invention provides a method for controlling a clutch of an automatic manual transmission (AMT) vehicle, which learns the characteristic curve of the clutch by performing a full lock control of the clutch after slip control, thereby reducing the minute slip control time, thereby improving the durability of the clutch. Furthermore, this method can shorten the clutch-on time for the subsequent shift by predicting the time when the shift is started again after the full lock control, and by restarting the micro-slip control.

Description

technical field [0001] The present invention relates to a method of controlling a clutch of a vehicle equipped with an automatic manual transmission (AMT), which appropriately controls the timing of a slight slip control and a full lock control of the clutch while the vehicle is moving. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] In order to improve fuel efficiency and power transmission efficiency, the AMT system directly connects an engine and a clutch, but on the other hand, such an AMT system has no damping factor, and thus generates vibration or slip of the clutch according to a change in torque. Therefore, an algorithm that predicts the transmission torque characteristics of the clutch in real time may be needed. [0004] Therefore, the torque stroke curve (T-S curve) of the dry clutch is usually used to predict the transmission torque ch...
