Abstract
A diagnostic function for an internal-combustion engine whose power is set by way of a power-determining signal that is determined from a first signal from a determination device, and a second signal determined by a torque controller, based on engine torque. A selection device sets either the determination device or the torque controller to be dominant for the power determining signal. When the values of the engine torque are not plausible, an error mode is set. With the setting of the error mode, the dominance is retained when the determination device is dominant. When the torque controller is dominant, a change of the dominance takes place.
