Abstract
A method of controlling a dual clutch transmission, may include releasing a pressure of a non-driveshaft clutch and engaging a gear of a non-driveshaft; applying a first pressure to the non-driveshaft clutch and disengaging the gear of the non-driveshaft; determining a drag torque on the basis of a first rotation speed change rate of the non-driveshaft; releasing the first pressure and engaging the gear of the non-driveshaft; applying a second pressure to the non-driveshaft clutch and disengaging the gear of the non-driveshaft; determining a touch point torque on the basis of a second rotation speed change rate of the non-driveshaft; and adjusting a touch point of the non-driveshaft clutch on the basis of a net torque which is a difference between the touch point torque and the drag torque.
