Summary:The present invention includes the steps of: determining whether the current temperature of oil is less than a predetermined reference temperature; determining whether an EOP RPM is less than a predetermined minimum drive RPM if the current temperature of the oil is less than the reference temperature; reducing a target line pressure and command RPM of an EOP by applying a predetermined first reduction ratio for a first predetermined time if the EOP RPM is less than the minimum drive RPM; determining whether the vibration of the EOP RPM occurs more than a predetermined reference vibration if the EOP RPM is more than the minimum drive RPM; and reducing the target line pressure and command RPM of the EOP by applying a predetermined second reduction ratio for a second predetermined time if the vibration of the EOP RPM is more than the reference vibration. Accordingly, the present invention helps improve the durability of an EOP and an inverter. 본 발명은 오일의 현재온도가 소정의 기준온도 미만인지를 판단하는 단계; 상기 오일의 현재온도가 상기 기준온도 미만이면, EOP RPM이 소정의 최소구동RPM 미만인지를 판단하는 단계; 상기 EOP RPM이 최소구동RPM 미만이면, 소정의 제1설정시간 동안, 상기 EOP의 목표라인압과 지령RPM에 소정의 제1감소비율을 적용하여 감소시키는 단계; 상기 EOP RPM이 최소구동RPM 이상이면, 상기 EOP RPM의 진동이 소정의 기준진동 이상으로 발생하는지 판단하는 단계; 상기 EOP RPM의 진동이 상기 기준진동 이상이면, 소정의 제2설정시간 동안, 상기 EOP의 목표라인압 또는 지령RPM에 소정의 제2감소비율을 적용하여 감소시키는 단계를 포함하여 구성된다.
