Abstract
A control method of a power delivery system of a vehicle, may include determining a theoretical target slip velocity of a torque converter for slipping a damper clutch, detecting a real slip velocity of the damper clutch in a real driving condition based on the theoretical target slip velocity, expressing distributions of the real slip velocity according to an engine load ratio into a control line diagram, and controlling the real target slip velocity of the damper clutch according to the control line diagram by using the engine load ratio.
