Definitions

  • the present invention relates to a hybrid powertrain for a motor vehicle, with an internal combustion engine serving to drive the motor vehicle, with an electric machine for driving the motor vehicle, with a clutch arrangement, with a gear arrangement connected to the clutch arrangement, which has a plurality of gear stages, and with a planetary gear arrangement, which is coupled to the internal combustion engine, with the electric machine and with an input of the clutch assembly or coupled.
  • the present invention relates to a method for driving such a hybrid drive train.
  • the integration of a dual-clutch transmission into a hybrid drive train is particularly advantageous, in particular when the electric machine is connected to the input of one of the partial transmissions.
  • the electric machine can serve as the sole drive source (via the associated partial transmission), wherein the internal combustion engine can be started in the state by means of the electric machine, with a recuperation in all operating modes is possible, with a boost operation is possible and a stall is possible, etc.
  • the gearing arrangement of such a hybrid powertrain typically includes a plurality of gear stages, with the number of forward gear stages provided tending to increase so that automated dual clutch transmissions may have six, seven, eight or more gear ratios.
  • Hybrid drive trains which are designed to provide one or two "electric" gear stages for an electric machine and to provide three or four gear steps for an internal combustion engine are known, for example, from the documents DE 10 2013 022 142 A1 or DE 10 2010 063 092 A1.
  • Another hybrid powertrain is known from the document DE 10 2013 206 176 A1, wherein the internal combustion engine and the electric machine feed on a shaft of a transmission.
  • the document EP 1 526 304 B1 relates to a dual-clutch transmission which does not show any special adaptation to a hybrid application.
  • gears for even gear ratios are arranged on a first transmission input shaft and gear wheels for odd gear ratios on a second transmission input shaft.
  • a synchronization unit is provided for selectively rotationally fixed connection of a gear for a straight gear stage and a gear for an odd gear ratio. Higher loaded gears, such as first gear, second gear and reverse gear are arranged directly next to camp levels.
  • the document DE 10 2010 063 3 1 A1 discloses a further hybrid drive train, with a planetary gear, wherein a first element of the planetary gear mechanism serves the fixed connection of a transmission input shaft, wherein a second element of the fixed drive Serving an electrical machine is used, wherein two elements of the planetary gear can be coupled via a clutch and wherein a third element of the planetary gear by means of a switching element in a first switching position to an internal combustion engine and in a second switching position to a housing or a stator can be coupled.
