Title: Method of controlling a change of speed for an automatic transmission in vehicles
Inventor: LEE SANG CHEOL
IPC: F16H61/04
Filed: 2001-08-31
Abstract: PURPOSE: A speed shift control method of an automatic transmission is provided to improve speed shift performance by controlling a return shift differently before and after the start point of a physical speed shift upon returning to a four-speed from a two-speed. CONSTITUTION: A return shift to a four-speed is ordered in a process of a kick down shift of the four-speed to a two-speed(S100). A decision of a speed shift is delayed for a certain time if the return shift control is before the start point of the speed shift(SB). The shift to the four-speed is performed after adjusting the opening of a throttle. The RPM(revolution per minute) of a turbine is read at the decision point of the two - four speed shift if the return shift control is after the start point of the speed shift. The control for the shift to the four-speed is performed when a factor of generation of a shift shock does not exist even if the present shift control is performed. The control for the shift to the four-speed is accomplished after enough back up time if the condition of a change amount in turbine RPM is not a shift condition.

Abstract: PURPOSE: A power factor compensating circuit is provided to stabilize a system and minimize a power consumption by making the compensating circuit operate with respect to a switching mode power supply and not operate at a standby mode. CONSTITUTION: A power supply part(100) includes a main switch(Qsw) coupled to the first coil(L11) of a primary side of a transformer(T) and performs power factor compensation when the main switch performs a switch operation by a turn-on duty ratio. A switch control part(201) include the second coil of the primary side coupled to the first coil. The switch control part receives a feedback signal from an external load supplied with a power induced at the primary side and generates the first drive high voltage by controlling a switch element so as to be switched by a predetermined duty ratio at a normal operation mode. The switch control part generates the first drive low voltage by controlling at a burst mode where the switch element repeats an on-state and an off-state by a constant ratio. An output part(500) includes a secondary coil(L12) supplied with a power from the primary side and is connected to the external load. A power factor compensation control part(300) controls the main switch and is supplied with the second drive voltage coupled with the first drive high voltage or the first drive low voltage. A drive voltage applying part(400) controls such that the second drive voltage is dropped below an operating voltage at the standby mode.
