There are systems and methods for controlling a vehicle system provided which comprises a motor that is selectively switched off during idle stop conditions of the engine, wherein the system further comprises a hydraulic circuit which comprises a hydraulically operated transmission component, a memory and a transmission fluid auxiliary pump. An exemplary method includes during a first state of Leerlaufstoppmotorabschalten, in which the accumulator pressure is above a threshold supply of pressurized transmission fluid from the accumulator to the hydraulic circuit, while the auxiliary pump is deactivated. The method further includes, during a second state of Leerlaufstoppmotorabschalten, in which the accumulator pressure is below the threshold, operating the auxiliary pump and supplying at least some pressurized transmission fluid from the working pump to the hydraulic circuit without passing through the memory.
