Embodiment Construction

[0022] 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.

[0023] see figure 1 , the power source of the engine (E) is configured to be supplied to the drive wheels (W) via a dual clutch transmission (DCT); the two clutches 1 constituting the DCT are respectively controlled by the clutch actuator 3; The shift gear is shifted by a shift actuator 4, which selects and drives the synchronizing device; the clutch actuator 3 and the shift actuator 4 are controlled by a controller 5; the controller The signal of the accelerator position sensor (APS) 7 is received to receive the operation amount of the accelerator pedal.

[0024] Of course, in addition to the above information, the controller 5 also receives information such as engine torque and engine speed information.

Abstract

The present disclosure relates to a clutch control method for a vehicle. The method is configured to include a slip entry determining step of determining, by a controller, whether a driver in a full-lock control releases an accelerator pedal to thereby enter into a micro-slip control; a monitoring step of monitoring, by the controller, whether the release of the clutch occurs, in case of enteringinto the micro-slip control as a result of performing the slip entry determining step; a control amount adjusting step of resetting a feedback amount of a clutch control torque in the case that the release of the clutch occurs; and a clutch control step of controlling the clutch according to the clutch control torque as reset by the control amount adjusting step to thereby prevent or minimize therelease of the clutch.

Description

technical field [0001] The present invention relates to a method for controlling a clutch of a vehicle, and more particularly, to a technique for controlling a clutch torque during running of a vehicle equipped with a dry clutch. Background technique [0002] The statements in this section merely provide background information related to the present invention and may not constitute prior art. [0003] In a vehicle having a dry clutch mounted to a vehicle dynamometer (for example, an automatic manual transmission (AMT) or a dual clutch transmission (DCT), if the controller controlling the clutch accurately recognizes the torque characteristic of the clutch, The vehicle can then control precise clutch transfer torque. [0004] Since the transmission torque characteristic of the clutch varies almost every moment with respect to the stroke of the actuator operated by itself through temperature or other various factors, the dry clutch tries to obtain a value close to the actual ...
