According to one embodiment of the present invention, a method for controlling the shifting and engine clutch joining of a hybrid vehicle having an engine clutch between an engine and a motor comprises the following steps of: detecting a driver kick down during electric vehicle mode driving; starting shifting when detecting the driver kick down; controlling a difference value 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 engine speed control; when the synchronization is completed, performing torque blending by joining the engine clutch; and when a required torque target is reached through the torque blending, finishing the shifting. According to the present invention, acceleration delay of the hybrid vehicle is solved and linearity of acceleration before and after shifting is improved.
