Abstract: A motor vehicle drive unit has an electric machine, a transmission, and a supply circuit to jointly supply the electric machine and the transmission with lubricant and/or coolant. The supply circuit has a first collecting region and a second collecting region. A suction side of a conveying device opens to the second collecting region. The first collecting region is below the transmission so that during operation, the first collecting region collects at least one partial return flow, which flows off after being supplied from the transmission. The second collecting region is below the electric machine and above the first collecting region. During operation the second collecting region collects at least one partial return flow, which flows off after being supplied from the electric machine. The first and second collecting regions are connected so that lubricant and/or coolant can be discharged from the second collecting region into the first collecting region.

Abstract: A drive unit with a parking lock arrangement has a parking lock gear, a parking lock pawl, and a parking lock tappet. An actuation unit can move the tappet against a shifting force into a locking shift position in which the tappet enables an actuating movement of the pawl toward a release position, in which the pawl enables a rotary movement of the parking lock gear. The actuation unit is operatively connected to a shift actuator system of a manual gearbox having at least two speeds. The actuation unit is configured to transfer the tappet from the locking shift position to the releasing shift position by means of spaced-apart cams when one of the speeds is engaged. In a neutral operating state, where no speed is engaged and the power train is interrupted, the actuation unit releases the actuating movement of the tappet toward the locking shift position.

Abstract: A method of operating a vehicle having a hybrid drive, a transmission with shift elements, a drive output with a brake, a main transmission with input shafts, an output shaft and planetary gear sets (PG1, PG2).

Another shift element couples a further element of gear set (PG1) either to the output shaft or a housing. An electric machine is permanently connected to an element of gear set (PG2). If, while driving with a transmission gear engaged, the drive output brake is engaged for a full brake application, a shift element of the transmission is first relieved by the electric machine and/or a brake assigned to one of the input shafts and then subsequently disengaged to decouple the combustion engine from the drive output.
