摘要： A method for operating a drivetrain of a motor vehicle, the drivetrain having a drive unit with an internal combustion engine and with at least one turbocharger, a driver demand torque being determined as a function of a present accelerator pedal actuation (PI), a drive unit torque (MNEW) which is dependent on the driver demand torque (MDD) provided by the drive unit via a load shock damping facility such that the drive unit torque (MNEW) is built up as a function of the driver demand torque via load filter gradients of the load shock damping facility, and wherein in the case of a relatively high driver demand torque, to ensure a comfortable and dynamic build-up of the drive unit torque using the or each turbocharger, a nominal value (MNOM,2) for an air-based torque is increased more quickly to a maximum value than a nominal value (MNOM,1) for an ignition-based torque.
