PROBLEM TO BE SOLVED: To provide a hydraulic control device for a vehicle capable of securing a necessary hydraulic pressure in generating requested driving force in a low vehicle speed region where an output of a mechanical oil pump is instable.SOLUTION: When driving force requested by a driver generates in a low vehicle speed region where a vehicle speed is less than a first vehicle speed V1 instable in an output of a mechanical oil pump O/P driven by a motor/generator MG, an electric oil pump M/O/P driven by a sub-motor S/M, is driven so that a second hydraulic pressure P2 becomes higher than a compensation hydraulic pressure Pobtained by subtracting a first hydraulic pressure P1 from a necessary hydraulic pressure Pdetermined according to the requested driving force.SELECTED DRAWING: Figure 3 |
