Abstract
A method for operating a hybrid drive includes the steps of: providing an internal combustion engine, an electric machine, a converter, and a drive shaft, the internal combustion engine including a combustion engine, the converter being electrically connected to the electric machine, the internal combustion engine and the electric machine being connected to each other in a torque-transmitting manner by way of the drive shaft; determining a rotational motion signal associated with the drive shaft, the rotational motion signal being determined by way of an electrical converter variable of the converter; and determining a signal characterization of a momentary curve of the electrical converter variable, the signal characterization indicating an intermittent cylinder operation of the combustion engine.
