Abstract

A power transmission system of a hybrid electric vehicle comprises an engine, a clutch, a primary motor, an ASG(Automated Shift Gear), a secondary motor, and a differential gear. The primary motor is combined between an output shaft of the clutch and an input shaft of the ASG. The secondary motor is combined between an output shaft of the ASG and an input shaft of the differential gear.

Description

field of invention [0001] Generally, the present invention relates to powertrains for hybrid electric vehicles. Background of the invention [0002] Generally, a hybrid electric vehicle (HEV) employs two power sources of an engine and a motor, and this becomes a feature that distinguishes HEVs from conventional vehicles employing an internal combustion engine. Therefore HEV must provide appropriate power system and variable speed control technology so that the power transmission of the two power sources can be maintained smoothly. [0003] Such as figure 1 As shown, the power from the engine 110 and the power from the electric motor 120 are not completely separated according to the conventional scheme of the power system of this HEV. Therefore, a good purely electric drive mode is difficult to achieve. Additionally, inertial and / or frictional loads of the engine 110 are active under regenerative braking, and these loads may reduce the efficiency of regenerative braking. ...
