Patent ID: 7121257

Claim:
A method for automatically controlling an internal combustion engine-generator unit, comprising the steps of: presetting a speed set value (nM(SL)) as a reference input; computing a first set injection quantity (qV 1 (SL)) by a speed controller substantially from the speed set value (nM(SL)) and an actual speed (nM(IST)); computing a limit injection quantity (qDBR) by means of a speed limitation curve (DBR); determining a second set injection quantity (qV 2 (SL)) from the first set injection quantity (qV 1 (SL)) or the limit injection quantity (qDBR); and setting an operating point of the internal combustion engine-generator unit by means of the second set injection quantity (qV 2 (SL)), the speed limitation curve (DBR) being variable as a function of the speed set value (nM(SL)).
