Abstract
A drive system for a vehicle comprises two electrical machines arranged between a combustion engine and an input shaft to a gearbox. The first machine rotor is connected with a planetary gear component, and the input shaft of the gearbox with another planetary gear component. The second machine rotor is connected with the output shaft of the combustion engine, which is also connected with another planetary gear component. A first locking means movable between a locked position, wherein the planetary gear's three components rotate at the same rotational speed, and a release position, wherein the components rotate at different rotational speeds. A second locking means movable between a locked position, and a release position wherein the combustion engine's output shaft is locked to a stationary element in the locked position and disconnected in the release position to rotate with the second machine rotor and a planetary gear component.
