Abstract

The invention concerns a drive system, especially for a motor vehicle, with a drive assembly, especially an internal combustion engine; an electric machine that is directly coupled or can be coupled to the drive shaft of the drive assembly, being designed such that it can start the drive assembly by merging in from standstill; and an automatic start-stop control of the drive assembly. The invention is also addressed to a method for operating such a drive system.
