Problems solved by technology

[0004] Specifically, the torque transmitted by a dry clutch varies greatly due to factors such as differences in components, degree of friction in relation to life cycle, thermal deformation due to high temperatures, and changes in the coefficient of friction of the discs, so we found that It is difficult to estimate the torque transmitted to the clutch while the vehicle is in motion
[0005] As mentioned above, when changes in clutch torque due to these various factors cannot be accurately determined, the clutch may slip excessively or produce vibrations, so we find it desirable to estimate and correct the torque characteristics of dry clutches in real time

Embodiment Construction

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

[0024] According to the control method of the vehicle dual-clutch transmission of the present disclosure, such as figure 1 and figure 2 As shown, it includes: a pre-engagement determination step S100, the controller 150 determines whether any gear on the input shaft 220 is pre-engaged; the clutch movement step S200, when the controller 150 determines to release the input shaft in the pre-engagement determination step S100 When any gear on the 220 is pre-engaged, an oscillating signal is generated to the release input shaft 220, and the clutch position value is increased by controlling the clutch actuator 120 of the release input shaft 220; the signal determination step S300 is determined by the controller 1...

Abstract

The present disclosure provides a control method and a control system of a dual-clutch transmission for a vehicle. The method includes: a pre-engagement determining step of determining, by a controller, whether any one of the gears is pre-engaged; a clutch movement step of generating an oscillating signal to a release input shaft and incrementing a clutch position value for said release input shaft; and a signal determination step, It is determined whether an oscillating signal generated to the release input shaft is sensed at the engage input shaft.

Description

technical field [0001] The present disclosure relates to a dual clutch transmission control method and a control system thereof for learning a contact point of a dual clutch transmission (dual clutch transmission, dual clutch transmission) when a vehicle is running. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] A dual clutch transmission is a system for automatically controlling a manual transmission that uses a dry clutch to transmit engine torque, unlike a normal automatic transmission (A / T) that uses a torque converter and a wet multi-plate clutch. [0004] Specifically, the torque transmitted by a dry clutch varies greatly due to factors such as differences in components, degree of friction in relation to life cycle, thermal deformation due to high temperatures, and changes in the coefficient of friction of the discs, so we found that It is d...
