POWER TRAIN SYSTEM OF HYBRID ELECTRIC VEHICLE TO LOWER POWER DISCONNECTION

摘要

PURPOSE: A power train system is provided to reduce a disconnection of power train during transmission by separating the inertia of an engine during regenerative braking or power-actuated travel. CONSTITUTION: A power train system comprises a first motor(250) mounted between the output shaft of a clutch(220) connected to an engine(210) and the input shaft of a transmission(230); and a second motor(260) mounted between the output shaft of the transmission and the input shaft of a decelerating unit(240). The power train system transmits power in an engine mode, motor mode, hybrid mode and a regenerative braking mode in accordance with the operation of the engine, first motor, second motor and the clutch.
