Problems solved by technology

[0011] The single-mode scheme has the advantage of not requiring torque transmission mechanisms such as clutches and brakes for shift control, but has the disadvantage that efficiency decreases when the vehicle is traveling at high speeds, and therefore, fuel efficiency is low and additional torque boosting devices are required to Applying a single-mode approach to large vehicles

Abstract

The present invention discloses a power transmission system of a hybrid electric vehicle including: an input shaft; an output shaft; first, second and third planetary gear sets; a first rotational shaft, a second rotational shaft, a third rotational shaft, a fourth rotational shaft; a fifth rotational shaft; a sixth rotational shaft; and three friction elements mutually selectively connecting rotational shafts to each other or selectively connecting the respective rotational shafts and the transmission housing such that the power transmission system of the hybrid electric vehicle can suppress conversion to an ENG mode by providing sufficient power performance at a time of wide open throttle (WOT) launching and maximally use power of an engine at a time of conversion to a first HEV mode and a third HEV mode.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to and the benefit of Korean Patent Application No. 10-2014-0105268 filed on Aug. 13, 2014, the entire contents of which are incorporated herein by reference for all purposes. technical field [0003] The present invention relates to a power transmission system for a hybrid electric vehicle, and more particularly, to a system that can provide sufficient power performance at wide-open throttle (WOT) launch and when transitioning to the first HEV mode and the first HEV mode. A power transmission system of a hybrid electric vehicle that maximizes the use of engine power to suppress transition to ENG mode in the three HEV mode. Background technique [0004] Eco-friendly technologies for vehicles are core technologies that affect the survival of the future vehicle industry, and advanced vehicle manufacturers devote their full efforts to developing eco-friendly vehicles to meet environmental a...
