Abstract: A method for controlling a hydraulic circuit for a twin-clutch transmission, wherein the hydraulic circuit comprises a first and a second clutch that can be hydraulically actuated, the pressures of said clutches being controlled with respective pressure control valves, and wherein a safety circuit substantially guarantees a safe state for the hydraulic circuit if a malfunction occurs. The safety circuit is configured such that if a partial malfunction affecting only one of the two clutches occurs, the affected clutch is disengaged and if a total malfunction affecting both clutches occurs, the clutch with the lower clutch pressure at the time of the total malfunction is disengaged and the other clutch with the higher clutch pressure at the time of the total malfunction remains engaged to maintain the transfer of torque via said clutch.
