Abstract
A method for operating an internal combustion engine, including the following steps: forming a value for a maximum admissible torque, forming a dimension figure for the actual torque and comparing the dimension figure to the value and triggering an error response if the actual torque exceeds the maximum admissible torque. The value for the maximum admissible torque is developed from a first approximation value and an estimated value for the torque contribution of an intervention of a fault regulator. Also, a control unit as well as its use.

A method for operating an internal combustion engine, comprising:
- setting a torque output of the internal combustion engine via a power actuator as a function of a signal of a driver's command sender;
- forming a value for a maximum admissible torque of the internal combustion engine;
- forming a dimension figure for an actual torque of the internal combustion engine and comparing the dimension figure to the value for the maximum admissible torque;
- triggering an error response if the actual torque exceeds the value for the maximum admissible torque;
- and
- superimposing an intervention of a fault regulator on an activating signal of the power actuator,
- wherein the value for the maximum admissible torque is formed from a linking of a first approximation value to an estimated value for a torque contribution of the intervention of the fault regulator, the first approximation value being formed as a function of the signal of the driver's command sender.
A control unit for controlling an internal combustion engine, comprising:
- means for setting a torque output of the internal combustion engine via a power actuator as a function of a signal of a driver's command sender;
- means for forming a value for a maximum admissible torque of the infernal combustion engine;
- means for forming a dimension figure for an actual torque of the internal combustion engine and comparing the dimension figure to the value for the maximum admissible torque;
- means for triggering an error response if the actual torque exceeds the value for the maximum admissible torque;
- and
- means for superimposing an intervention of a fault regulator on an activating signal of the power actuator,
- wherein the value for the maximum admissible torque is formed from a linking of a first approximation value to an estimated value for a torque contribution of the intervention of the fault regulator, the first approximation value being formed as a function of the signal of the driver's command sender.
