ABSTRACT:
A method for operating a drivetrain of a motor vehicle having in the force flow direction and in the following order an internal combustion engine, a clutch, an electric motor, a transmission and an axle gearset, or an internal combustion engine, a clutch, an electric motor, a transmission input shaft, a transmission and an axle gearset. The electric motor is used for pre-lubricating and warming the transmission such that, with the vehicle clutch disengaged, the lubricant pump of the transmission is driven by the electric motor so bearings are supplied with lubricant before the engine is started, and the heat, produced by splashing the lubricant, additionally warms the transmission.
