Control method and apparatus for protecting damper clutch of vehicle

A control apparatus for protecting a damper clutch of a vehicle from a repetitive tip-in (an action of pressing an accelerator pedal to realize acceleration)/tip-out (an action of depressing the accelerator pedal to release the acceleration), the control apparatus comprising:

• a solenoid for the damper clutch, the solenoid being configured to control an operation of the damper clutch;
• and
• a Transmission Control Unit (TCU) configured to control a transmission and the solenoid for the damper clutch by cooperating with an Engine Control Unit (ECU), wherein the TCU comprises:
• a slip power calculation unit configured to calculate a slip power in real time on the basis of a turbine speed of a torque converter, an engine speed, a capacity coefficient of the torque converter, a clutch torque, and a hydraulic torque;
• an intention determination unit configured to determine whether the repetitive tip-in/tip-out that is intentionally performed occurs or not on the basis of a change in the slip power that is calculated in real time for a set time by the slip power calculation unit;
• and
• a protection logic operation unit configured to operate a damper clutch protection logic set to restrain a slip of the damper clutch by increasing hydraulic pressure applied to the damper clutch when it is determined that the repetitive tip-in/tip-out that is intentionally performed occurs.
