Problems solved by technology

[0005] Dry clutches have characteristics in which the transmitted torque of a dry clutch depends on a variety of factors such as tolerances of the individual parts of the assembly and wear caused by long-lasting processes, thermal deformation caused by high temperatures and changes in the friction coefficient of the discs, etc. ), therefore, it is difficult to estimate the torque transmitted to the dry clutch while driving

Abstract

An estimating method for transmitting torque of a dry type clutch in a vehicle, may include a slip determining step of determining by a processor whether only one clutch slips between an engine and a transmission, a transmitting torque estimating step of estimating a current transmitting torque of the dry type clutch by using a torque observer when the only one clutch slips as a result of performing the slip determining step, and an updating step of reflecting the current transmitting torque of the dry type clutch estimated in the transmitting torque estimating step and an actuator torque in the transmitting torque estimating step to a T-S (Torque-Stroke) curve.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0121629 filed on Oct. 30, 2012, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a technique for estimating the transfer torque of a dry clutch provided between an engine and a transmission in a vehicle, and more particularly, to a technique capable of accurately estimating the operating stroke of an actuator and the transfer torque of a dry clutch relationship between the technology to properly control dry clutches used in automatic transmissions such as automated manual transmissions (ATM) by means of actuators. Background technique [0004] An automated manual transmission such as ATM (Automated Manual Transmission), or DCT (Dual Clutch Transmission), is an automatic control manual transmission mechanism that transmits engine torque to the gear shift...
