FIELD: machine building.
SUBSTANCE: invention relates to automotive industry. Hydraulic control system for vehicle having engine, contains oil pumps, oil reception part, oil channels and check valves. First oil pump is mechanical pump and driven by vehicle moving force source. Second oil pump is electrically driven pump and driven by electric motor. Oil channels connect oil pumps with oil reception part. First check valve is located between combination point and first oil pump. Second check valve is located between combination point and second oil pump. Combination point is part, where first oil channel and second oil channel are combined with each other. Combination point and second oil pump are connected by means of third oil channel. Third oil channel includes throttle mechanism.
EFFECT: enabling improving of hydraulic control system operating characteristics.
