METHOD AND DEVICE FOR CONTROLLING ELECTRIC OIL PUMP

摘要

PROBLEM TO BE SOLVED: To provide a method for controlling an electric oil pump stably supplying oil into a transmission even if input voltage to an electric motor driving the electric oil pump is fluctuated.SOLUTION: In this method for controlling the electric oil pump driven so that when an engine is stopped by an idle stop, oil pressure is generated in the transmission by the electric oil pump or oil is filled in the transmission, the electric motor driving the electric oil pump is so controlled that the amount of oil supplied into the transmission by the electric oil pump is kept constant with respect to the fluctuation of the input voltage to the electric motor.
