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

A device for calibrating engine clutch delivery torque of a hybrid vehicle, comprising:

• an engine clutch configured to connect an engine with a driving motor or disconnect the engine from the driving motor;
• and
• a controller configured to determine an engagement control amount of the engine clutch according to a difference between speeds of the engine and the driving motor,
• wherein the controller determines 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, the controller extracts 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 the controller applies a weighted value to each of the extracted previous delivery torque and the determined current delivery torque to calibrate a delivery torque included in the map table.

A non-transitory computer readable medium containing program instructions executed by a processor, the computer readable medium comprising:

• program instructions that determine 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;
• program instructions that determine 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;
• program instructions that extract 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
• program instructions that apply a weighted value to each of the extracted previous delivery torque and the determined current delivery torque to calibrate a delivery torque included in the map table,
• wherein the calibrated delivery torque is provided for engagement of the engine clutch when the hybrid vehicle is traveling in a hybrid electric vehicle mode.
