Abstract

A method and an arrangement for controlling a drive unit are suggested wherein a maximum permissible value of an output quantity is determined. This maximum permissible value is compared to the actual value and, when the permissible value is exceeded by the actual value, reaction measures are initiated. The maximum permissible value is filtered at least in one operating state in accordance with filter means including a filter and a dead zone member. Furthermore, the maximum permissible value is continuously reduced in dependence upon the approaching of at least one quantity to a limit value. This quantity represents an operating state.
