hybrid power train, method for controlling such hybrid power train, vehicle comprising such hybrid power train, computer program for controlling such hybrid power train, and computer program product comprising program code
The present invention relates to a hybrid power train comprising an internal combustion engine (4); a gearbox (2) with an input shaft (8) and an output shaft (20); a gearbox variation (11) connected to the output shaft (20); a first planetary gear (10) connected to the input shaft (8); a second planetary gear (12) connected to the first planetary gear (10); a first electronic equipment (14) connected to the first planetary gear (10); a second electronic equipment (16) connected to the second planetary gear (12); at least one pair of gears (60, 72) connected to the first planetary gear (10) and output shaft (20); and at least one pair of gears (66, 78) connected to the second planetary gear (12) and output shaft (20), wherein the internal combustion engine (4) is connected with the first planetary gear (10) via of the input shaft (8). the gearbox variation (11) comprises a third planetary gear (110) with a third star wheel (112) and a third planetary wheel axle (114), and a fourth clutch device (130) is arranged to connect and disconnecting the third star wheel (112) and a third planetary wheel axle (114), and a fourth clutch device (130) is arranged to connect and disconnect the third star wheel (112) with / from the third wheel axle planetary (114). The invention also relates to a method for controlling such a hybrid power train (3) in order to achieve a shift to a high varying position without torque interruption.
