Abstract:
1. A method of operating a drivetrain ( 1 ) of a vehicle during thrust operation, the drivetrain comprising an internal combustion engine ( 2 ), an electric machine ( 3 ) and a transmission device ( 4 ), the electric machine ( 3 ) being located in a force flow between the combustion engine ( 2 ) and the transmission device ( 4 ) and a shift element ( 8 ), with a continuously variable transmission capacity, being located between the electric machine ( 3 ) and a drive output ( 5 ) such that a nominal output torque (m_fahr_soll) delivered to the drive output ( 5 ) is a function of the transmission capacity of the shift element ( 8 ), the method comprising the steps of: adjusting the transmission capacity of the shift element ( adjusting a speed (n_ reducing a speed of the combustion engine (
