A damper clutch control method for an automatic transmission vehicle is provided to reduce a speed shifting shock by decreasing a control pressure at a predetermined slope during a predetermined delay time. A turbine rotation number detector(10) detects a current turbine rotation number, which is used as an output torque of a torque converter. A throttle opening detector(20) detects an opening amount of a throttle. A vehicle speed detector(30) detects a speed of a vehicle. An engine rotation number detector(40) detects a rotation number of an engine, which is used as an input torque of the torque converter. A transmission speed detector(50) detects a current transmission speed. A TCU(Transmission Control Unit)(60) receives driving information from the turbine rotation number detector, the throttle opening detector, the vehicle speed detector, the engine rotation number detector, and the transmission speed detector, and generates a control signal for an automatic transmission and a damper clutch. An actuator(70) receives the control signal from the TCU and controls the automatic transmission and the damper clutch. |
