1. A method for controlling an electric oil pump for a vehicle by using a control device in the electric oil pump for the vehicle having an engine, the method for controlling the electric oil pump comprising steps of:
- (A) determining whether the vehicle is stopped;
(B) deciding a target RPM of the electric oil pump;
(C) controlling an actual RPM at which the electric oil pump is actually driven based on the target RPM;
(D) controlling the actual RPM based on a torque or a current value of the electric oil pump; and
(E) stopping the electric oil pump based on the target RPM;
wherein the step (D) comprises a step of determining whether the torque or the current value is reduced when a difference between the target RPM and the actual RPM is equal to or smaller than a predetermined error value.

Abstract
The present disclosure provides a method for controlling the electric oil pump for a vehicle having an idle stop and go system. The system includes a control device for controlling the operation of the electric oil pump when the vehicle is stopped and restarted again. In the system, the operation of the electric oil pump is performed by an actual RPM control applying a target RPM of the electric oil pump and a torque or a current value of the electric oil pump.
