摘要:
The present invention relates to an oil pump control apparatus of a hybrid vehicle that controls an oil pump according to a demand of an output torque and oil temperature, and a method thereof. A oil pump control method includes controlling hydraulic line pressure by operating a oil pump at a maximum power if a starting demand for a hybrid vehicle is detected, calculating a viscosity to correspond to an oil temperature in an engine stop mode and controlling a rotation speed of the oil pump at a low power, and calculating a viscosity according to a variation of a line pressure in a driving mode and controlling the rotation speed of the electric oil pump in either a low power, a middle power, and a high power state.
