The invention concerns a drive system, especially for a motor vehicle, with a drive assembly, especially an internal combustion engine (1); and at least one electric machine (4), which acts as an electromagnetic coupling in the drive train (2) of the drive system and/or as an active transmission synchronization device. The invention is also oriented to a method of operating a drive system.

[ We claim:] [2.] A drive system for a motor vehicle, comprisinga combustion engine (1) as the drive system,a drive train (2) for torque transmission from the combustion engine (1) to drive wheels (3) by means of a drive shaft (10) driven by the combustion engine (1) and an output shaft (55),a lock-up clutch (60) between the drive shaft (10) and the output shaft (55),an electrical machine (4) in the drive train (2) having at least two electromagnetic active units--a rotor (9) an a stator (8),wherein the rotor (9) is connected with one of the two shafts--the output shaft (55) or the drive shaft (10)--in a rotationally fixed manner and the lock-up clutch (60) is arranged between the rotor (9) and the other of the two shafts (10 or 55, respectively), andwherein the stator (8) is eitheri) in a first coupling state in which it is coupled with the other of the two shafts (10 or 55, respectively) in a rotationally fixed manner, thereby rotating together with such shaft (10 or 55, respectively), orii) in another coupling state in which it is disengaged from the other of the two shafts (10 or 55, respectively) and fixed against rotation,wherein the combustion engine (1) transfers its torque in the first coupling state and in case the lock-up clutch (60) is open to the drive wheels (3) via the electrical machine (4), with the latter then acting as an electromagnetic clutch, wherein, in the other coupling state, the combustion engine (1) transfers its torque via the then closed lock-up clutch (60) to the drive wheels (3), with the electrical machine (4) additionally applying torque to the then connected drive and output shafts (10, 55).
