摘要

The present invention provides an internal combustion engine comprising: an internal combustion engine (4); A gear box (2) having an input shaft (8) and an output shaft (20); A range gear box 11 connected to the output shaft 20; A first planetary gear set (10) connected to the input shaft (8); A second planetary gear set (12) connected to the first planetary gear set (10); A first electric machine (14) connected to the first planetary gear set (10); A second electric machine (16) connected to the second planetary gear set (12); At least one gear pair (60, 72) connected to the first planetary gear set (10) and the output shaft (20); And at least one gear pair 66 and 78 connected to the second planetary gear set 12 and the output shaft 20 so that the internal combustion engine 4 is connected to the first planetary gear set 10 To a hybrid power train. The range gearbox 11 includes a third planetary gear set 110 having a third sun wheel 112 and a third planetary wheel carrier 114 and a fourth clutch device 130 includes a third sun wheel (112) to and from the third planetary wheel carrier (114). The present invention also relates to a method of controlling such a hybrid powertrain in order to achieve a shift to a high range position without torque interruption.
