Method for actuating a hydraulic device

A method for actuating a hydraulic device, which provides a hydraulic supply to a torque-transmitting device, comprising:

• operating a first pump in a first operating state, wherein the first operating state has a primary pump rotational speed that provides a first fluid pressure to the torque-transmitting device via a fluid tract;
• based on a second fluid pressure being less than or equal to a target fluid pressure, initiating a switchover process by operating a second pump in a second operating state, wherein the second operating state has a secondary pump rotational speed that provides the second fluid pressure to the torque-transmitting device via the fluid tract;
• during operation of the hydraulic device, determining the secondary pump rotational speed for the switchover process based on a first power value for the second pump in a preceding switchover process;
• based on the second fluid pressure being greater than or equal to a second target fluid pressure, stopping operation of the second pump;
• and
• determining the first power value based on electrical energy consumed by the second pump at a completion time of the preceding switchover process and electrical energy consumed by the second pump at a completion time of a further preceding switchover process preceding the preceding switchover process in turn.
