Abstract
A method of controlling a damper clutch of a turbocharger mounted automatic transmission vehicle secures stable boost pressure to provide accelerating feeling is disclosed. The method may include detecting driving information from a turbocharger mounted vehicle to determine whether lock up conditions of a damper clutch are satisfied, determining an engine load by a gear shift stage and an engine speed when the lock up conditions of the damper clutch are satisfied, detecting supplied boost pressure to determine whether conditions of the engine load are satisfied, and canceling the lock up of the damper clutch for accelerating feeling when the boost pressure does not satisfy the conditions of the engine load.
Claims7
An apparatus for controlling a damper clutch of an automatic transmission, comprising:
- a driving information unit detecting overall driving information of a vehicle;
- a boost pressure unit detecting boost pressure supplied to a combustion chamber in accordance with an operation of a turbocharger;
- an actuator for locking up a damper clutch and canceling lock up of the damper clutch;
- and
- a controller for determining conditions of an engine load when driving information provided by the driving information unit satisfies lock up conditions of the damper clutch predetermined by a map and for canceling the lock up of the damper clutch when the boost pressure does not satisfy the conditions of the engine load.
