    Abstract: A hybrid vehicle control method includes: monitoring an electric oil pump (EOP) driving current in which an EOP is being driven at a predetermined target RPM, and determining whether the EOP driving current is in a predetermined reference range in which it possible to estimate a situation in which the EOP suctions air; determining whether a measured hydraulic pressure at a place receiving oil supplied by the EOP is less than reference hydraulic pressure when the EOP driving current is in the predetermined reference range; and temporarily decreasing line pressure and increasing an RPM of the EOP.

    Abstract: A pump motor control system provides for a low-pressure hydraulic pump and a high-pressure hydraulic pump on one shaft of a pump motor. A method includes detecting information including engine speed, a shift range selected, a rotation speed of the pump motor, and hydraulic pressure in a high-pressure part, controlling the rotation speed of the pump motor to be the same as the engine speed, when engine is turned on and the P range or the N range is selected by the shift lever, generating hydraulic pressure for operating a friction element in the high-pressure part by increasing the rotation speed of the pump motor, when the shift lever is moved to the D range or R range, and keeping the hydraulic pressure in the high-pressure part stable, by controlling the rotation speed of the pump motor in accordance with the hydraulic pressure at the high-pressure part.

    Abstract: A method for controlling an electric oil pump (EOP) of a hybrid vehicle may include determining whether or not the hybrid vehicle is in a decelerating situation in an EV mode, driving the EOP at an RPM at a point L, corresponding to a minimum RPM of the EOP to form a target line pressure of a transmission, upon determining that the hybrid vehicle is decelerating in the EV mode, determining whether or not an RPM of a turbine is equal to or greater than a predetermined reference RPM, and driving the EOP at an RPM acquired by adding a predetermined additional RPM to secure an additional flow rate of automatic transmission fluid supplied to a balance chamber of an engine clutch to the RPM at the point L, upon determining that the RPM of the turbine is equal to or greater than the predetermined reference RPM.
