Abstract
A method for operating a hybrid motor vehicle having an internal combustion engine and at least one electric machine is provided. At least one of the electric machines supplies a varying torque to the internal combustion engine such that cyclic irregularities of the internal combustion engine during idling are reduced and, at the same time, the internal combustion engine is operated during idling with an ignition angle and a volumetric efficiency optimized for this operating state and without retarding the ignition angle for building up a torque reserve.
