摘要： A method for operating a DCT hydraulic power control system and a DCT hydraulic power control system are provided to reduce power consumption by improving control characteristics. An HPS(High Pressure Section) supplies oil to actuators of DCT. An LPS(Low Pressure Section) supplies the oil to an LCS(Lubrication and Cooling System) of DCT. A regulator unit(030) transmits the overflown oil from the HPS to the LCS in order to maintain constantly the pressure of the HPS. A method for operating a DCT hydraulic power control system includes a process for applying the oil through a check valve(060) of a first branch line of a low pressure part by closing a direction valve(050) in a low speed mode and operating two outlets(X,Y) of a pump unit(020) in a parallel state, a process for opening the direction valve of a main line in an intermediate speed mode by generating on/off pilot pressure and operating an on/off valve(040) of a connective line, and a process for maintaining a first pressure outlet of the pump unit at high pressure and maintaining a second pressure outlet of the pump unit at low pressure in a high speed mode by operating the on/off valve.
