Method for determining the output pressure of an electrically driven oil pump of a vehicle transmission, and method for adapting a pressure model of such an oil pump

摘要

Method for determining the outlet pressure of a first, electrically driven oil pump (IEP) of a vehicle transmission (G), wherein the first oil pump (IEP) is arranged parallel to a second oil pump (FZP), which is driven by a shaft (GW1) of the vehicle transmission (G ) is mechanically driven to promote hydraulic fluid in a hydraulic circuit (K1) of the vehicle transmission (G), and method for adapting a pressure model of the electrically driven first oil pump.
