Driveline for a vehicle, the vehicle with the drive train as well as methods for operating the drive train

In hybrid vehicles, are used as traction motors alternatively or parallel internal combustion engines and electric motors. It is an object of the present invention to provide a drive train for a vehicle which represents an alternative to the known prior art. For this purpose, a drive train 1 for a vehicle 2 having a first interface 6 for coupling an electric motor 3, with a second interface 7 for coupling an internal combustion engine 4, with an output shaft 5, with a planetary gear section 8, wherein the planetary gear section 8, three shafts 9, 10 having 11, wherein a first shaft 9 with the first interface 6 and a second shaft 10 to the second interface 7 is drivingly coupled, and proposed two transmission gear sections and three coupling devices.
