    摘要： 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.

    摘要： An oil pressure control device for a vehicle is configured such that, when switching from an oil pressure supply by means of a mechanical oil pump (O/P) driven by a motor/generator (MG) to an oil pressure supply by means of an electric oil pump (M/O/P) driven by a sub-motor (S/M), a supply ratio of oil supplied from the mechanical oil pump (O/P) and a supply ratio of oil supplied from the electric oil pump (M/O/P), are adjusted based on an oil pressure difference between a first oil pressure (P1) and a second oil pressure (P2), via first and second flapper valves (101a), (102a). When the first oil pressure (P1) becomes less than or equal to a pump drive threshold (P O/P ), an increase in the second oil pressure (P2) is initiated, and the first oil pressure (P1) and the second oil pressure (P2) are made to match at a predetermined equilibrium oil pressure (P ba ) higher than a required line pressure (PL ne ).
