HYBRID POWERTRAIN WITH A GEARBOX AND METHOD TO CONTROL THE HYBRID POWERTRAIN |
摘要 |
A hybrid powertrain that includes a combustion engine (4) and a gearbox (2) with an input shaft (8) and an 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 electrical machine (14) connected to the first planetary gear (10); a second electrical machine (16) connected to the second planetary gear (12); at least one gear pair (G1, 60, 72) connected to the first planetary gear (10) and to the output shaft (20); and at least one gear pair (G2, 66, 78) connected to the second planetary gear (12) and to the output shaft (20), a countershaft (18) provided between the combustion engine (4) and the gearbox (2) so that the engine (4) can be disconnected from the gearbox (2). Also disclosed is a method for controlling the disclosed hybrid powertrain (3). Also a vehicle (1) includes such a gearbox (2), and a method to control such a gearbox (2). Also a computer program (P) to control a gearbox. |

1. A hybrid powertrain comprising a combustion engine (4) and a gearbox (2) with an input shaft (8) and an 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 electrical machine (14) connected to the first planetary gear (10); a second electrical machine (16) connected to the second planetary gear (12); at least one gear pair (G1, 60, 72) connected to the first planetary gear (10) and to the output shaft (20); and at least one gear pair (G2, 66, 78) connected to the second planetary gear (12) and to the output shaft (20), characterised in that a clutch device (106) is provided between the combustion engine (4) and the gearbox (2) so that the engine (4) can be disconnected from the gearbox (2). |
