Problems solved by technology

Since a hydraulic control valve including a spool valve is applied to each solenoid valve, the hydraulic piping of the valve body is complicated and uses a large number of parts
Therefore, the manufacturing cost will increase
[0012] Since a reduced pressure should be generated to control the pressure control valve, the control area may be limited and the response may be slower

Abstract

A hydraulic control system of an automatic transmission for a hybrid vehicle provides for simplifying structure of a valve body and improving responsiveness as a consequence of directly controlling hydraulic pressure supplied to friction elements. The hydraulic control system may operate first and second clutches and first and second brakes selectively according to each driving mode, and may include: a first proportional control solenoid valve for selectively supplying forward pressure and reverse pressure supplied from a manual valve to the first clutch; a second proportional control solenoid valve for selectively supplying line pressure supplied from a primary regulator valve to the second clutch; a third proportional control solenoid valve for selectively supplying the line pressure supplied from the primary regulator valve to the first brake; and a fourth proportional control solenoid valve for selectively supplying the forward pressure supplied from the manual valve to the second brake.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2010-0100448 filed in the Korean Intellectual Property Office on Oct. 14, 2010, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a hydraulic control system for an automatic transmission of a hybrid vehicle. More particularly, the present invention relates to a hydraulic pressure control system for an automatic transmission of a hybrid vehicle, which simplifies the structure of a valve body and improves responsiveness by directly controlling hydraulic pressure supplied to frictional elements. Background technique [0004] In general, a hybrid vehicle is a vehicle that generates drive torque by efficiently combining two or more different types of power sources. Most hybrid vehicles have an engine that generates power by using fuel and an electric motor that generates powe...
