The invention relates to a method for controlling the oil supply device of an automatic planetary transmission, comprising a main oil pump (HP), which is mechanically drivably connected to the drive shaft of an internal combustion engine (VM), and an auxiliary oil pump (ZP) that may be driven via a controllable electric motor, the automatic transmission (ATG) being part of a parallel hybrid powertrain of a motor vehicle having an input shaft (5), which may be connected via a separating clutch (K) to the drive shaft (2) of the internal combustion engine (VM) and is permanently drivably connected to the rotor (4) of an electric machine (EM).
In order to achieve an oil supply to the automatic transmission (ATG) as and when needed, it is provided that the current oil requirement (PHD<sub2>—</sub2>soll) of the automatic transmission is determined as a function of at least one currently captured operating parameter, and that the delivery rate (PZP) of the auxiliary oil pump (ZP) is set, by a correspondingly actuation of the associated electric motor, in the combustion and combined driving mode below a minimum input speed of the main oil pump (HP) and in the electric driving mode to at least the total oil requirement, and at least in the combined driving mode above the minimum input speed of the main oil pump (HP) is set to at least the residual oil requirement exceeding the delivery rate (PHP) of the main oil pump.
