A drive system for a vehicle comprises two electrical machines (9, 30) arranged between a combustion engine (2) and an input shaft (3a) to a gearbox. The rotor of a first (9) of the electrical machines is connected with a component (11) of a planetary gear, and the input shaft (3a) of the gearbox is connected with another component (12) of such planetary gear. The rotor of the second electrical machine (30) is connected via a transmission (33) with the output shaft (2a) of the combustion engine, which is connected with another component (10) of the planetary gear. A first locking means (35) may be moved between a locked position, in which the planetary gear's three components rotate at the same rotational speed, and a release position in which the components are allowed to rotate at different rotational speeds. A second locking means (34) may be moved between a locked position, in which the output shaft (2a) of the combustion engine is locked with said additional component of the planetary gear, and a release position, in which the combustion engine's output shaft is disconnected from such a component. |
