Abstract
A system for controlling a lock-up of engine clutch may include an engine and a motor; the engine clutch mounted between the engine and the motor and configured to selectively transmit power of the engine between the engine and the motor; a hybrid starter generator (HSG) connected to a crank pulley of the engine and driven to start the engine; and a controller connected to the HSG and configured to determine a virtual engine speed in an engine firing process and a torque reduction ratio of the HSG according to the virtual engine speed after an engine cranking process and determine a correction reduction ratio with respect to the torque reduction ratio of the HSG using a difference value between the virtual engine speed and an actual engine speed, and adjust an increase or a decrease of the torque reduction ratio of the HSG to synchronize an engine speed with a motor speed for the lock-up of the engine clutch.
