Abstract
The present invention relates to a hybrid powertrain for a vehicle. The hybrid powertrain comprising: an internal combustion engine; a torque converter; a first and a second electric machine electrically coupled to each other. The hybrid powertrain further comprises a planetary gear set, comprising a first, a second and a third member. The internal combustion engine is mechanically engaged to the second member of the planetary gear set via the torque converter. The first electric machine is arranged mechanically engaged to the first member of the planetary gear set. The second electric machine is arranged mechanically engagable to the second and third member of the planetary gear set so as to establish a plurality of operating modes of the hybrid powertrain.
