Method and device for learning engine clutch delivery torque of hybrid vehicle

A non-transitory computer readable medium containing program instructions for learning engine clutch delivery torque of a hybrid vehicle, the computer readable medium comprising:

• program instructions that determine whether power transference of a transmission transmitting output from an engine of the vehicle and a motor of the vehicle is interrupted;
• program instructions that control a speed of the motor to be maintained at a first speed when the power transference of the transmission is interrupted;
• program instructions that calculate a first delivery torque of an engine clutch that connects the engine with the motor or disconnects the engine from the motor, based on the first speed and a second speed of the motor which is generated after the engine clutch is engaged;
• program instructions that control the speed of the motor to be maintained at the second speed by releasing the engine clutch after the first delivery torque is calculated;
• and
• program instructions that calculate a second delivery torque of the engine clutch based on the second speed and a third speed of the motor which is generated after the engine clutch is engaged.
