Claim Text:
1. A method for operating a powertrain of a motor vehicle, the method comprising: operating a powertrain, the powertrain comprises: determining, based on a load of the powertrain when the gearbox-sided auxiliary output is activated or engaged, a load to be borne by the powertrain when performing a target gearshift to a target gear; determining, based on the determined load, a first set of synchronous elements of the powertrain for a first gearshift procedure and a second set of synchronous elements of the powertrain for a second gearshift procedure different from the first gearshift procedure; and conducting the target gearshift to the target gear based on whether a transmission brake is capable of bearing the determined load when the gearbox-side auxiliary output is engaged; wherein the target gearshift is conducted through the first gearshift procedure with the first set of synchronous elements when a transmission brake is capable of bearing the determined load and the gearbox-sided auxiliary output is engaged; and wherein the target gearshift is conducted through the second gearshift procedure with the second set of synchronous elements when the transmission brake is not capable of bearing the determined load.
