The invention relates to a drive system for motor vehicles with in particular an internal combustion engine (13) as the main drive in the main drive train (10) of the motor vehicle, with auxiliary units (19) of the motor vehicle to be driven and a secondary drive train (11) which is coupled to the main drive train and with a starter Generator (20) working electrical machine. In order to optimize the power balance and the fuel consumption of such a drive system, it is provided that the auxiliary drive train (11) has its own auxiliary unit drive (22), which can be coupled to the starter generator (20), and that the auxiliary unit drive (22) and the starter Generator (20) can be coupled both individually and jointly with or without a main drive (13) for driving the motor vehicle with its drive axle (17). |
