The present invention relates to a hydraulic circuit of a transmission for a hybrid vehicle and a control method thereof. According to the present invention, the hydraulic circuit of a transmission for a hybrid vehicle comprises: a mechanical oil pump; an electric oil pump separately provided from the mechanical oil pump; a first lubrication line formed to provide oil from the mechanical oil pump to a transmission lubrication system; a regulator valve installed to form line pressure by adjusting oil pressure of the electric oil pump; a second lubrication line formed to provide discharging pressure of the regulator valve to a first motor generator and a second motor generator; and a transmission control portion provided to control a transmission factor by the line pressure adjusted from the regulator valve.

    본 발명은 기계식 오일펌프와; 상기 기계식 오일펌프와는 독립적으로 구비된 전동식 오일펌프와; 상기 기계식 오일펌프로부터의 오일을 변속기윤활계통으로 공급하도록 형성된 제1윤활라인과; 상기 전동식 오일펌프로부터의 오일압을 조절하여 라인압을 형성하도록 설치된 레귤레이터밸브와; 상기 레귤레이터밸브의 토출압을 상기 제1모터제너레이터 및 제2모터제너레이터로 공급하도록 형성된 제2윤활라인과; 상기 레귤레이터밸브로부터 조절된 라인압으로 변속요소를 제어하도록 구비된 변속제어부를 포함하여 구성된다.
