The invention relates to a hybrid drive unit, in which for the most optimum possible synergetic use of the combustion engine drive and electromotive drive, a multi-speed clutch- and gear assembly is provided, in which both the combustion engine drive power and also the electromotive drive power is introduced into an input member of the clutch- and gear assembly. Hereby, numerous drive variants are made possible, which allow the drive machines to cooperate with each other according to requirements. The invention additionally relates to the method by which such a drive unit is operated.

Hybrid drive unit and method for its operation

The invention relates to a vehicle having a drive train, which comprises at least one first engine and a wheel, wherein a torque can be transmitted from the first engine to the wheel by the drive train, and wherein at least one first unit of the drive train is connected to an interface, by which rapid and simple replaceability of said unit is possible, wherein the interface is designed to be connected to a second unit, which is different from the first unit, wherein both units are designed to store electricity, to convert chemically bound energy into energy of rotation and/or to convert electricity into energy of rotation and/or to convert rotation energy of rotation into electricity.

Vehicle having drive train

A dual clutch transmission comprising a first partial transmission and a second partial transmission is provided. A first group of forward gears is allocated to the first partial transmission, a second group of forward gears is allocated to the second partial transmission, each one of the forward gears comprises a particular transmission ratio, two adjacent forward gears comprise adjacent transmission ratios with no transmission ratio of any other forward gear in between, and at least two adjacent forward gears are allocated to the second partial transmission. Further, such a control method for controlling the dual clutch transmission is provided that a torque transmitting gap is closed when gear shifting between the aforementioned two adjacent gears.
