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 of a planetary gear, and the input shaft of the gearbox with another component of such planetary gear. The rotor of the second electrical machine (30) is connected with the output shaft (2a) of the combustion engine, which is also connected with another component of the planetary gear. A first locking means (34) 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 (33) is moveable between a locked position, in which the combustion engine's output shaft is locked to a stationary element (35) in the vehicle, and a release position, in which the output shaft of the combustion engine is disconnected from the stationary element, and free to rotate with the rotor (32) of the second electrical machine and a component (10) in the planetary gear. |
