ABSTRACT:
A hydraulic arrangement for controlling a twin-clutch transmission of a motor vehicle. The hydraulic arrangement has a hydraulic energy source for supplying the hydraulic arrangement with hydraulic energy with a hydraulic medium; a pressure accumulator for storing the hydraulic energy; and a clutch cooling device for cooling clutches of the twin-clutch transmission with the hydraulic medium. A transmission lubrication process and/or a transmission cooling process for cooling and/or lubricating a transmission of the twin-clutch transmission with the hydraulic medium is/are carried out, in addition to a prioritization process for prioritizing the supply of the pressure accumulator before the clutch cooling, and the clutch cooling before the transmission lubrication and/or transmission cooling by means of the hydraulic medium.
