    • 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.
    • 提供了用于操作DCT液压功率控制系统和DCT液压功率控制系统的方法,以通过改进控制特性来降低功耗。 HPS(高压段)为DCT的执行器供油。 LPS(低压段)将油提供给DCT的LCS(润滑和冷却系统)。 调节器单元(030)将溢出的油从HPS传送到LCS,以便恒定地保持HPS的压力。 一种用于操作DCT液压动力控制系统的方法包括通过以低速模式关闭方向阀(050)通过低压部分的第一分支管线的止回阀(060)来施加油的过程,并且操作两个 平行状态下的泵单元(020)的出口(X,Y),通过产生开/关先导压力打开中间速度模式的主线的方向阀并操作开关阀的过程(040 ),以及用于在高压下维持泵单元的第一压力出口并且通过操作开/关阀在高速模式下将泵单元的第二压力出口保持在低压的过程。

    • The present disclosure relates to a method and a system for learning and controlling a kiss-point of an engine clutch by sensing changes in engine torque and motor torque or changes in motor speed by gradually increasing engine clutch hydraulic in vicinity of a previous kiss-point while a relative speed between an engine and a motor under no-load condition is maintained at a constant value. An exemplary embodiment of this disclosure includes a step of determining whether power transmission transmitted from a transmission, which transmits an output from the engine and the motor is cut-off or not; a step of controlling the motor to maintain a motor speed setting different from the engine speed under the engine in operating condition and the power transmission of the transmission under cut-off condition; a step of detecting changes in motor conditions by increasing applied hydraulic of the engine clutch at a predetermined rate; and a step of calculating a kiss-point of the engine clutch on the basis of the changes in motor condition.
