Abstract

A drive device for a motor vehicle includes a primary powertrain and a secondary powertrain, wherein the primary powertrain includes a combustion engine for generating a total torque; a torque distribution device coupled to the combustion engine and including a first and a second output, wherein the torque distribution device is designed to provide a first partial torque in mechanical form at its first output derived from the total torque, and to provide a second partial torque in electrical form at its second output derived from the total torque; and a transmission which is coupled to the first output of the torque distribution device; wherein the secondary powertrain includes an electric machine which is coupled to the second output of the torque distribution device; wherein the torque distribution device includes a torque limiting device which is designed to limit the first partial torque to a presettable threshold value.
