SYSTEM AND METHOD FOR CONTROLLING HYDRAULIC PRESSURE OF DAMPER CLUTCH

摘要

Disclosed is a method for controlling hydraulic pressure of a damper clutch, including the steps of determining a hydraulic pressure control mode of a damper clutch according to traveling conditions of a vehicle and conditions of the damper clutch; determining a hydraulic pressure control value according to the hydraulic pressure control mode; determining a target waveform of engine speed and a target waveform of turbine speed according to the hydraulic pressure control mode; detecting an engine speed waveform and a turbine speed waveform in the hydraulic pressure control mode; determining whether or not the detected engine speed waveform and the detected turbine speed waveform correspond to the target engine speed waveform and the target turbine speed waveform; and controlling the hydraulic pressure control value in such a manner that the detected engine speed waveform and the detected turbine speed waveform correspond to the determined target waveforms of engine speed and turbine speed.;COPYRIGHT KIPO 2014;[Reference numerals] (AA) Hydraulic pressure control value; (BB,CC,DD,EE) Time; (FF) Increase hydraulic pressure; (GG) Decrease hydraulic pressure; (HH) Determine a hydraulic pressure control value [S20]; (II) Determine a target control waveform [S30]; (JJ) Compare a measured waveform with a target waveform [S50]; (KK) Control the hydraulic pressure control value [S60]
