摘要： A method of controlling an electric oil pump configured for a vehicle, may include a step of determining whether a vehicle has entered a sloped road, a step of determining whether a drive motor of the vehicle is in one or more overheatable conditions when it is determined that the vehicle has entered a sloped road, a step of determining whether the overheatable condition is maintained over a preset reference time when it is determined that the vehicle is in the over-heatable condition; and a step of supplying a pulse to an RPM input for the electric oil pump when it is determined that the duration of the over-heatable condition exceeds the preset reference time.
