Summary:One aspect of the present invention relates to a method and a device for controlling hydraulic pressure in an automatic transmission, and more particularly, to a method and a device for controlling hydraulic pressure, in an automatic transmission, which detect an occurrence of an interlock and to solve the same. A hydraulic pressure control method and control device according to an embodiment of the present invention can improve a sense of transmission by precise and stable control of each friction element, and eliminate possibility that the friction element will operate with an unspecified wrong combination, and improve durability of the automatic transmission by preventing a clutch of the automatic transmission from being burned, and the like. 본 발명의 일 측면은 자동변속기의 유압 제어방법 및 그 제어장치에 관한 것으로, 더욱 상세하게는 자동변속기에 있어서 인터락(Interlock) 발생을 감지하고, 이를 해소하기 위한 유압 제어방법 및 그 제어장치에 관한 것이다. 본 발명의 일 실시예에 따른 유압 제어방법 및 제어장치는 각 마찰요소의 정밀하고 안정된 제어로 변속감을 향상시킬 수 있으며, 정해지지 않은 잘못된 조합으로 마찰요소가 작동될 개연성을 배제하며, 자동변속기의 클러치 소손을 방지하는 등 자동변속기의 내구성을 향상시키는 효과를 제공한다.
