Apparatus for controlling electric oil pump

A method of controlling an electric oil pump that supplies oil using an electric motor as a power source, comprising:

• setting a target number of revolutions for determination higher than a required number of revolutions corresponding to an operation request of the electric oil pump, and executing control of the electric motor so that the number of revolutions of the electric oil pump approaches the target number of revolutions for determination;
• detecting an operation state of the electric oil pump while executing the control of the electric motor;
• determining the occurrence of idling in the electric oil pump based on an operation state detection value of the electric oil pump;
• and
• outputting a control signal corresponding to a determination result of the occurrence of the idling.
