본 발명은 유압테스트를 통해 목표압력 생성여부와 목표압력 생성을 위해 소요되는 시간을 판단하여 오일유량의 부족현상을 검출하는 기술에 관한 것으로, 본 발명에서는, 차량의 이그니션온시, 유압테스트를 위한 목표압력을 생성하도록 펌프에 구동명령을 인가하는 단계; 상기 목표압력을 생성하는지 여부를 판단하는 단계; 및 상기 목표압력을 생성하지 못한 경우, 상기 목표압력 생성에 필요한 펌프 구동명령의 최대값을 제한하는 단계;를 포함하여 구성되는 AWD시스템의 유압시스템 점검방법 및 장치가 소개된다.

    The present invention relates to a technology of detecting a lack of oil flow by determining whether or not a target pressure is generated and the time required for generating the target pressure through a hydraulic test. In the present invention, introduced are a method and an apparatus for checking a hydraulic system of an AWD system, which comprise the following steps of: applying a pump driving command to a pump in order to generate a target pressure for the hydraulic test when an automobile is ignited on; determining whether the target pressure is generated; and limiting a maximum value of the pump driving command required to generate the target pressure when the target pressure is not generated.
