1. A method for controlling a hybrid electric vehicle comprising:
connecting a first motor directly connected to an engine to a second motor directly connected to a transmission input terminal through a dual mass flywheel of the hybrid electric vehicle;
determining a target angular acceleration of the first motor based on a gear shifting progress rate so that an angular acceleration of the first motor follows the target angular acceleration of the transmission input terminal when a gearshift is performed in the transmission; and
controlling, by a controller, a torque of the first motor based on the target angular acceleration of the first motor.
