Patent Number Title Of Patent Date Issued
7774119 Shift control system of automatic transmission and method thereof August 10, 2010
A shift control system of an automatic transmission and a method thereof include controlling the off-going and on-coming clutches according to hydraulic pressures of the off-going and on-coming clutches calculated based on a flare amount when a flare occurs, controlling the on-coming
7706951 Shift control system of automatic transmission and method thereof April 27, 2010
A shift control system of an automatic transmission and a method thereof include controlling the off-going and on-coming clutches according to hydraulic pressures of the off-going and on-coming clutches calculated based on a flare amount when a flare occurs, controlling the on-coming
7392126 Line pressure control system and method of an automatic transmission June 24, 2008
A dynamic characteristic of a hydraulic pressure is significantly enhanced since a line pressure control system. A method employed by the system includes determining whether a vehicle is in a power-on state, determining whether a damper clutch is being engaged when the vehicle is in
7381151 Upshift control system of automatic transmission and method thereof June 3, 2008
A power-on 2-3 upshift control method for an automatic transmission comprises: determining whether a power-on 2-3 upshift condition exists; extracting an initial hydraulic pressure control duty and hydraulic pressure control duty depending on an input torque from a map table for an o
7247126 Method and apparatus for shift control of an automatic transmission July 24, 2007
Whenever a 4 to 3 shift condition is satisfied during a 3 to 4 upshift, 4 to 3 shifting is started before the 3 to 4 shifting is finished. The 4 to 3 shifting is executed according to a predetermined hydraulic control pattern. Therefore, responsiveness in shifting is enhanced.
7125363 Control method for suppressing blow-up phenomenon during power-on 2-3 upshift of automatic trans October 24, 2006
A control method for suppressing a blow-up phenomenon during a power-on 2-3 upshift is provided. Disclosed steps include determining whether a predetermined shift compensation control entrance condition exists, determining whether a blow-up occurs if it is determined that the predete
6993424 Method and apparatus for controlling a solenoid valve of an automatic transmission of a vehicle January 31, 2006
When a target duty of a solenoid valve of an automatic transmission of a vehicle lies in a predetermined duty range, the solenoid valve is driven for an adjusted over-excitation period obtained by adjusting a base over-excitation period on the basis of an over-excitation period adjus
