摘要： 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.

摘要： A method for controlling a hydraulic pressure refilling operation for an engine clutch of a vehicle includes determining whether the vehicle travels using power of a driving motor with an engine clutch maintained in a disengaged state, and upon determining that the vehicle travels using power of the driving motor with the engine clutch maintained in the disengaged state, determining whether loss of hydraulic pressure has occurred, and upon determining that loss of hydraulic pressure has occurred, controlling a hydraulic pressure refilling operation such that working fluid in a reservoir is supplied to the actuator with the engine clutch in an engaged state, and controlling the driving motor so that the driving motor outputs a compensated torque by compensating for an effect of a load torque, generated by a non-operating engine, on a torque of the driving motor.
