Abstract

A hybrid drive device includes an internal combustion engine, an electric machine and an impulse start module which comprises two clutches and a flywheel mass. A method for operating the hybrid device includes opening the first clutch of the impulse-start module and establishing a start-up requirement for the internal-combustion engine. The method also includes closing the first clutch with the second clutch in an open or closed position for a start of the internal-combustion engine.
