Clutch control method for vehicle equipped with dual clutch transmission

A clutch control method of a vehicle provided with a double clutch transmission, the clutch control method comprising:

• determining, by a controller, when the vehicle is travelling at a lowest shifting stage or a highest shifting stage and pre-engagement of a proximate shifting stage is completed;
• learning a driveshaft clutch torque by the controller;
• storing a learned driveshaft clutch torque and a current clutch temperature and initiating a timer when the controller determines that the learned driveshaft clutch torque is considered reliable by the controller learning the driveshaft clutch torque;
• determining, by the controller, a plurality of conditions including passage of time to determine when a touch point learning of a non-driveshaft clutch is necessary;
• disengaging, by the controller, the proximate shifting stage of a non-driveshaft to a neutral when the controller determines that the touch point learning is necessary and performing the touch point learning of the non-driveshaft;
• and
• updating, by the controller, a touch point of the non-driveshaft to a learned value when the touch point learning is completed and pre-engaging the disengaged proximate shifting stage again;
• and
• wherein the updated touch point is used by the controller when controlling the non-driveshaft clutch later.
