Abstract
A method for calibrating engine clutch delivery torque of a hybrid vehicle includes: determining an engagement control amount of an engine clutch which connects an engine with a driving motor or disconnects the engine from the driving motor based on a difference between speeds of the engine and the driving motor; determining a current delivery torque corresponding to the engagement control amount of the engine clutch that controls the engine clutch to be in a lock-up state and a temperature of the engine clutch; extracting a previous delivery torque that corresponds to the engagement control amount that controls the engine clutch to be in the lock-up state and the temperature and is included in a map table; and applying a weighted value to each of the extracted previous delivery torque and the determined current delivery torque to calibrate the delivery torque included in the map table.
