Abstract

An oil pump control apparatus of a hybrid vehicle is provided that controls an oil pump according to a demand of an output torque and oil temperature. In particular, hydraulic line pressure is controlled by operating an oil pump at maximum power if a starting demand for a hybrid vehicle is detected. Viscosity is calculated as well to correspond to an oil temperature in an engine stop mode and a rotation speed of the oil pump is controlled at a low power. Additionally, viscosity is also calculated according to a variation of a line pressure in a driving mode and the rotation speed of the electric oil pump is controlled in either a low power, a middle power, and a high power state as well.
