The present invention provides a method for controlling inner pressure of a fuel tank system including a fuel tank (150) and a pressure release valve, which can be controlled. The method for controlling inner pressure of a fuel tank system comprises: determining whether a predetermined steam discharge danger exists, wherein the predetermined steam discharge danger relates to discharge of steam from a main volume of the fuel tank (150) to space allowing access by an operator; operating the pressure release valve according to a first pressure threshold value when the danger exists; and operating the pressure release valve according to a second pressure threshold value higher than the first pressure threshold value when the danger is not exist. In case a danger of releasing pressure through a filler head of the fuel tank exists, the inner pressure of the fuel tank is prevented from being increased to pressure higher than the first predetermined threshold value.
연료 탱크 (150) 및 제어가능한 압력 해제 밸브를 포함하는 연료 탱크 시스템 내부의 압력을 제어하는 방법이 제시되어 있다. 본 방법은: - 미리 결정된 증기 배출 위험이 존재하는지를 판단하는 것으로서, 상기 미리 결정된 증기 배출 위험은 상기 연료 탱크 (150) 의 메인 용적으로부터 조작자에게 접근가능한 공간으로의 증기 배출과 관련되어 있는, 상기 판단하는 것; - 상기 위험이 존재하면, 제 1 압력 한계치에 따라서 상기 압력 해제 밸브를 작동시키는 것; - 상기 위험이 존재하지 않으면, 제 1 압력 한계치보다 높은 제 2 압력 한계치에 따라서 상기 압력 해제 밸브를 작동시키는 것으로 구성된다.
