Method and control device for operating a vehicle driveline

A method for operating a powertrain of a vehicle, wherein the powertrain features a first electrical machine with first power electronics, a second electrical machine with a second power electronics, and a transmission connected between the electrical machines and an output, the method comprising:

• executing a powershift, wherein one of the first electrical machine and the second electrical machine is used as a main driving machine, and wherein the other of the first electrical machine and the second electrical machine is used for tractive force support during the execution of the powershift;
• determining that an actual temperature of at least one of the electrical machines and/or an actual temperature of at least one of the power electronics is greater than a temperature limit value, and/or when a target electric current flowing through at least one of the electrical machines and/or at least one of the power electronics is greater than a current limit value;
• and
• adapting a powershift to be executed so as to limit heating of the respective electrical machine and/or the respective power electronics.
