A hydraulic control device includes: a mechanical oil pump (O/P) that is driven by a motor/generator (M/G) and that generates a first hydraulic pressure (P1); an electric oil pump (M/O/P) that is driven by a sub-motor (S/M) and that generates a second hydraulic pressure (P2); and a controller (10). When a demanded drive force from a driver is generated while in a low-vehicle-speed region which is lower than a first vehicle speed (V1) at which the output of the mechanical oil pump (O/P) becomes unstable, the controller (10) controls the electric oil pump (M/O/P) such that the second hydraulic pressure (P2) becomes larger than a compensative hydraulic pressure (Pα) found by subtracting the first hydraulic pressure (P1) from a necessary hydraulic pressure (Pne) determined in accordance with the demanded drive force.
