PROBLEM TO BE SOLVED: To provide a hydraulic control device for a vehicle capable of suppressing power consumption of a sub-motor S/M for driving an electric oil pump while securing a necessary line pressure in stopping the electric oil pump.SOLUTION: A state of stopping a motor/generator MG and driving an electric oil pump M/O/P is shifted to a state of starting the motor/generator MG and stopping the electric oil pump M/O/P during regulation of a pressure by a line pressure regulation valve 104 for regulating a discharge pressure of a mechanical oil pump O/P driven by the motor/generator MG and/or a discharge pressure of the electric oil pump M/O/P driven by the sub-motor S/M. Here, a working fluid discharge flow of the electric oil pump M/O/P is lowered when the total flow of a working fluid discharge flow of the mechanical oil pump O/P and the working fluid discharge flow of the electric oil pump M/O/P is a pressure regulation limit flow of the line pressure regulation valve 104 or more.SELECTED DRAWING: Figure 3 |
