A control apparatus of a hybrid vehicle having an electric oil pump includes an engine clutch selectively engaging an engine and a drive motor; an automatic transmission changing a power generated from the engine by engagement and releasing of a friction element into a required torque depending on a speed; a hydraulic pressure sensor sensing an oil pressure supplied to the engine clutch; a temperature sensor sensing an oil temperature discharged from the electric oil pump; a hybrid control unit (HCU) controlling the electric oil pump to selectively engage the engine clutch depending on a driving state; and a transmission control unit (TCU) controlling the electric oil pump to supply transmission control pressure to the friction element. The electric oil pump includes an oil motor and a pump to supply the operating hydraulic pressure to the engine clutch and the friction element.

Apparatus for controlling hybrid vehicle having engine oil pump and method thereof

An oil pump system of a hybrid vehicle may include an electric oil pump which supplies operating hydraulic pressure to the transmission based on a speed command; a data detector which detects data for controlling the electric oil pump; and a controller which sets a driving mode of the electric oil pump based on the data detected by the data detector, determines a basic flow rate of the set driving mode, determines a final flow rate by compensating for the basic flow rate, and applies the speed command to the electric oil pump, in which the operating hydraulic pressure is supplied to the transmission only by the electric oil pump, and the speed command is determined based on target hydraulic pressure, an oil temperature, and the final flow rate.

Oil pump system of hybrid vehicle and method for controlling the same

A device for controlling fail-safe of a hybrid vehicle capable of providing fail-safe running by controlling drive of an electric oil pump with a generation voltage of a hybrid starter and generator (HSG) or a drive motor when a main relay may be cutoff due to failure of a high voltage component may include a method having determining whether the hybrid vehicle proceeds to a fail-safe mode due to a main relay opened by failure of a high voltage component during running of the hybrid vehicle or not, detecting a generation voltage of an HSG or a drive motor when the proceeding to the fail-safe mode may be determined, and generating oil pressure by controlling driving of an electric oil pump according to a generation amount of the HSG or the drive motor in running in the fail-safe mode or in a stop state.

Device for controlling fail-safe of hybrid vehicle and method thereof

A method for determining an operating state of elements of a transmission may include acquiring rotational speeds of both members constituting the elements, determining whether the rotational speeds of the members may be the same, and determining that the elements may be directly connected when the rotational speeds of the members may be the same, and that the elements may be disconnected or slip when the rotational speeds of the members may be different.
