Abstract
A method and a device for operating a drive unit provide a switch between half-engine operation and full-engine operation. A switch takes place between two operating states of a first component of the drive unit as a function of a first performance quantity of the drive unit. A switch takes place between two operating states of a second component of the drive unit as a function of a second performance quantity of the drive unit. A check is performed whether switching between two operating states of the second component results in a shift of the first performance quantity over a switching threshold for switching between two operating states of the first component, and if so, the switch between the two operating states of second component is delayed until a switch between the two operating states of first component has occurred.
