Abstract

A drive system for a hybrid vehicle having an internal combustion engine includes an electric motor and a clutch device which has a frictional locking element and a positive locking element that is connected parallel to the frictional locking element. The clutch device is configured to couple the internal combustion engine into the drive system and to be switched into at least the following states: a) open positive locking element and closed frictional locking element when starting and/or synchronization of the internal combustion engine, b) closed positive locking element and closed frictional locking element or closed positive locking element and open frictional locking element when the internal combustion engine is running and synchronized such that an internal combustion engine drive output action is generated, and c) open positive locking element and open frictional locking element when the internal combustion engine is stopped such that purely electric motor drive of the vehicle is provided.
