Abstract

A control method for controlling gear-shifting and lock-up of an engine clutch in a hybrid vehicle includes: detecting a kickdown shift by a driver while the hybrid vehicle is driving in an electric vehicle mode; starting gear-shifting when the kickdown shift is detected; controlling a difference between an engine speed and a motor speed to be equal to or less than a first reference value; synchronizing the engine speed and the motor speed through an engine speed control; performing torque blending by locking up the engine clutch when the synchronization is completed; and ending the gear-shifting when a target required torque is reached through the torque blending.
