Abstract

A method and a device for operating a drive unit, a computer program product having program code and a computer program which allow for an adaptation of a torque loss even outside of an idling operating state of the drive unit. In this instance, the losses of an output variable of the drive unit, in particular of a torque, are adapted. The losses are adapted during a shutdown of the drive unit.
