Abstract
A method and an arrangement for controlling a drive unit of a motor vehicle wherein at least one of the following quantities is determined: torque, power or throttle flap angle. This quantity is compared to the maximum permissible value and, when the maximum permissible value is exceeded by the determined quantity, fault reaction measures are initiated. The maximum permissible value is formed in dependence upon the time-dependent change of the rpm of the drive unit.
