Abstract
A hybrid drive device has an internal combustion engine, a clutch transmission which has at least one free partial transmission and a partial transmission connected to an electric machine with in each case a clutch, and at least one electric machine. In order to start the internal combustion engine, pulse energy is provided from an inertia of the clutch associated with the free partial transmission and/or a rotation in the free partial transmission.
