Abstract (en)
[origin: WO2016087146A1] A hydraulic supply arrangement in an automatic gearbox of a vehicle, having a primary hydraulic circuit (I) for providing a supply to gearbox components, having a secondary hydraulic circuit (II) for lubricating and cooling gearbox components, and having at least one pump (P) for generating a delivery volume flow in the hydraulic circuits (I, II) is proposed, wherein a detection device (E) is provided for detecting the present hydraulic medium volume flow in the secondary hydraulic circuit (II) for the purposes of adjustment of a required delivery volume flow of the pump (P). Also proposed is a method for controlling a pump of a hydraulic supply arrangement in an automatic gearbox of a vehicle, wherein the respectively present hydraulic medium volume flow in a secondary hydraulic circuit (II) for lubricating and cooling gearbox components is detected, wherein a volume flow demand is determined from a characteristic map relating to the present working range of the automatic gearbox, and wherein the delivery volume flow of the pump (P) is controlled in a manner dependent on the determined volume flow demand.
