摘要：A method for operating a drivetrain of a motor vehicle, the drivetrain having adrive unit with an internal combustion engine and with at least one turbocharger, a driverdemand torque being determined as a function of a present accelerator pedal actuation

(PI), a drive unit torque (M) which is dependent on the driver demand torque (M) providedby the drive unit via a load shock damping facility such that the drive unit torque (M) isbuilt up as a function of the driver demand torque via load filter gradients of the loadshock 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 eachturbocharger, a nominal value (M) for an air-based torque is increased more quickly to amaximum value than a nominal value (M) for an ignition-based torque.
