Summary:The method involves estimating two load torque rates and determining a load torque from the estimated load torque rates, where each load torque rate is assigned to a drive train component or a drive engine (2) arranged in a vehicle (1). A correcting variable is determined based on the estimated load torque for regulation of a speed of the drive engine. A measuring variable, which specifies an angular speed, is detected for determining the load torque rates, where the detected measuring variable is filtered. Independent claims are also included for the following: (1) a control device for controlling and regulating an operation of a drive engine, comprising a controller (2) a computer program executable on a computer for controlling and regulating a drive engine. Bei einer Antriebsmaschine wird zur Regelung einer Drehzahl eine Stellgröße in Abhängigkeit von einem geschätzten Lastmoment ermittelt. Die Antriebsmaschine ist in einem Fahrzeug angeordnet, wobei das Fahrzeug mindestens eine mittels einer unstarren Kopplung (22a, 22b) an die Antriebsmaschine (2) ankoppelbare Triebstrangkomponente (21a, 21b, 21c) aufweist. Um eine Reduzierung des Überschwingens und ein beschleunigtes Regelverhalten zu erreichen und um einen negativen Einfluss von Ruckelschwingungen bei der Drehzahlregelung zu verringern wird vorgeschlagen, dass zumindest zwei Lastmomentanteile (30a, 30b, 30c) durch Schätzung ermittelt werden, wobei jeder Lastmomentanteil (30a, 30b, 30c) jeweils einer Triebstrangkomponente (21a, 21b, 21c) zugeordnet ist. Das Lastmoment wird dann aus den ermittelten Lastmomentanteilen (30a, 30b, 30c) bestimmt.
