Abstract
In a method for operating a hybrid vehicle with an electric motor coupled with a multi-cylinder internal combustion engine having at least one cylinder that can be switched off, with a first partial momentum, from an overall momentum provided to the vehicle, being provided by the internal combustion engine and a second partial momentum from the electric motor, and the second partial momentum is used specifically for dampening a cyclic irregularity of the internal combustion engine. Further, means are provided in a hybrid vehicle control, by which the second partial momentum can be used specifically to dampen the cyclic irregularity of the internal combustion engine when one or, if necessary, several cylinders are switched off.
