Abstract: A method for operating a motor vehicle that has an internal combustion engine and an automated manual transmission, connected between the engine and a drive output. The transmission includes a shifting element group with a plurality of shifting elements. The transmission further includes an oil pump and an electric machine, both of which are integrated in the transmission and coupled to an input shaft of the transmission. The oil pump delivers a flow of transmission oil for cooling the shifting element group and cooling the electric machine, and the shifting elements of the shifting element group are controlled and shifted by an actuator system that is independent of the oil pump. When the motor vehicle is at rest, the oil pump is driven by the electric machine in order to cool the electric machine while the motor vehicle is at rest.

Abstract: A method for operating a motor vehicle having an engine and an electric machine, a transmission, a battery, and an exhaust treatment system having a particulate filter. The battery discharges during a charge-depleting mode of the electrical machine and charges when the electrical machine operates as a generator such that the battery charge state moves between lower and upper limits. If a filter regeneration requirement is detected, the filter is regenerated by raising the temperature of the exhaust gas. When the need for filter regeneration is detected, the battery is discharged to below the lower limit, in the charge-depleting mode of the electrical machine, prior to the regeneration. Subsequently, to regenerate the filter, the engine is operated to raise the exhaust gas temperature by increasing the torque provided by the engine, and the electric machine operates as a generator to charge the battery and/or operate an auxiliary electrical load.

Abstract: A method for operating a drive-train having two drives, a drive output, a manual transmission having a planetary gearset and two independent load paths. From the first and second drives, torque can pass to the output via respective first and second paths. The two drives can be coupled to respective elements of the planetary gearset, and the transmission is coupled to a web gear. To start, when torque passes to the output first via a second path gear and thereafter via a first path gear whose ratio is different from that of the second path gear, then before changing from the second path to the first path, the torque passed at the web gear is changed such that if torque desired by the driver is unchanged, despite the change from the second to the first path, the torque acting at the output remains constant.

Abstract: A method for controlling a hybrid drive of a vehicle is provided, for which a target drive torque (Ttarget) is provided by the internal combustion engine or the electrical engine, as the case may be, depending on an accelerator pedal position (AP) through a stored accelerator pedal characteristic curve for the drive of the vehicle. Upon a recognized driver's request for emission-free driving, the accelerator pedal characteristic curve is adjusted in such a manner that the maximum target drive torque (Ttarget) corresponds to the maximum electrical engine drive torque (TE-max).

Abstract: A method for operating a drive-train of a motor vehicle with a drive aggregate in the form of a hybrid drive system (3) which comprises at least one electric machine (2), an internal combustion engine (1), a transmission (5), a drive output (4) and a brake system which comprises at least one wear-free permanent brake (6).

To avoid disadvantages from shifting into neutral immediately after the motor vehicle is stationary, such as an increase in fuel consumption by a tractional torque operation of the converter, a disengagement impact upon shifting into the standby mode; an unexpected rolling of the vehicle, when stopping occurs on an incline following a shift into neutral. The automatic transmission (8), conforming to predetermined stopping conditions, shifts even during the driving state into neutral.
