Automated transmission and method for operating an automated transmission

A method for operating an automated transmission comprising:

• a hydraulic control device;
• one or more hydraulically actuated gear units, and at least one pressure control valve connected to an output-side hydraulic line providing an actuating pressure to the one or more hydraulically actuated gear units;
• wherein the hydraulic control device comprises:
• a control unit for setting actuating pressures on the gear units;
• a base pressure control valve for adjusting a hydraulic base pressure of the hydraulic control device;
• and a base pressure control device designed to control the base pressure control valve dependent on the actuating pressures;
• and wherein the automated transmission further comprises a device hydraulically connecting the base pressure control valve directly to the output-side hydraulic line such that the highest temporarily required actuating pressure can at any time directly act on the base pressure control valve;
• and the base pressure control device is configured to reduce the base pressure at least temporarily and therefore reduce the actuating pressure;
• said method comprising:
• adjusting by the base pressure control valve a hydraulic base pressure at the hydraulic control device;
• adjusting by suitable pressure control valves actuating pressures for actuating one or more transmission units;
• adjusting the hydraulic base pressure by one of the actuating pressures;
• reducing the base pressure at least temporarily to a lower actuating pressure;
• and
• directly switching through the actuating pressures to the base pressure control valve so that the highest temporarily required actuating pressure can at any time directly act on the base pressure control valve.
