An objective of the present invention is to provide a hydraulic control system for a vehicle, which can improve startability of an electric oil pump. The hydraulic control system for a vehicle comprises: a mechanical oil pump (MOP) (18); an electric oil pump (EOP) (19); a first oil passage connecting the MOP (18) and an oil supply unit; a second oil passage connecting the EOP (19) and the oil supply unit; a merging unit (42) where the first oil passage and the second oil passage merge; a first check valve (33) allowing oil to flow only in a discharging direction of the MOP (18); and a second check valve (40) allowing oil to flow only in a discharging direction of the EOP (19). A third oil passage (45) is formed between the EOP (19) and the merging unit (42), and bypasses the second check valve (40) to connect the merging unit (42) and the EOP (19). A throttle mechanism (46) is installed on the third oil passage (45), and restricts a flow rate of the oil discharged from the MOP (18).

    기계식 오일 펌프(MOP)(18)와, 전동 오일 펌프(EOP)(19)와, MOP(18)와 오일 공급부를 연통하는 제1 유로와, EOP(19)와 오일 공급부를 연통하는 제2 유로와, 상기 제1 유로 및 상기 제2 유로가 합류하는 합류부(42)와, MOP(18)의 토출 방향만 오일의 유통을 허용하는 제1 역지 밸브(33)와, EOP(19)의 토출 방향만 오일의 유통을 허용하는 제2 역지 밸브(40)를 구비한 차량의 유압 제어 장치에 있어서, EOP(19)와 합류부(42) 사이에, 제2 역지 밸브(40)를 우회하여 합류부(42)와 EOP(19)를 연통하는 제3 유로(45)를 형성하고, 그 제3 유로(45)에, MOP(18)가 토출하는 오일의 유량을 규제하는 교축 기구(46)를 설치한다.
