Abstract

A method and a device for operating a drive unit, in particular of a vehicle, are provided, which allow for an adaptation of losses of an output variable of the drive unit, in particular of a torque, which is precise and which restricts as little as possible a request to shut down the drive unit. For this purpose, the losses are adapted during at least one operating phase, in particular an idling operating phase, of the drive unit. With the conclusion of a successful adaptation, a shutdown of the drive unit is enabled.
