摘要: A method for operating a hydraulic system of an automatic transmission, in particular in a hybrid drivetrain, in which the hydraulic system comprises a main pump that is powered by an internal combustion engine and/or an electric drive motor, an electric auxiliary pump and a system pressure valve for setting a system pressure, to ensure various operating functions. In addition to the main pump, the electric auxiliary pump also supplies the hydraulic system with a volume flow of an operating medium. The loading of the electric auxiliary pump is determined in an electronic control unit with regard to the value of the system pressure and the loading of the electric auxiliary pump is limited, by the electronic control unit, with regard to the selected operating function.

摘要: A method for operating a drive train of a motor vehicle that includes at least a hybrid drive with a combustion engine and an electric motor, a transmission arranged between the hybrid drive and a drive output, and a clutch arranged between the combustion engine and the electric motor, such that when the combustion engine is stopped during electric operation of the drive train the combustion engine can be started by engaging the clutch between the combustion engine and the electric motor. Before the combustion engine is started by the electric motor at least one friction element, which is arranged between the hybrid drive and the drive output, is operated at a slipping limit.
