    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 electrical machine rotor is connected with a planetary gear component, and the input shaft of the gearbox is connected with another planetary gear component. The second electrical machine rotor is connected via a transmission with the output shaft of the combustion engine, which is connected with another planetary gear component. A first locking means may be moved between a locked position, wherein the planetary gear's components rotate at the same rotational speed, and a release position wherein the components rotate at different rotational speeds. A second locking means may be moved between a locked position, and a release position wherein the output shaft of the combustion engine is locked in the locked position and disconnected in the release position with said additional planetary gear component.

    Abstract: A gearbox having an input shaft (8) and an output shaft (20); a first epicyclic gear (10) connected to the input shaft (8); a second epicyclic gear (12) connected to the first epicyclic gear (10); a first electrical machine (14) connected to the first epicyclic gear (10); a second electrical machine (16) connected to the second epicyclic gear (12); a first main shaft (34) connected to the first epicyclic gear (10); a second main shaft (36) connected to the second epicyclic gear (12). A first coupling unit (56) disengagingly connects two rotatable components (22, 26, 50) at the first epicyclic gear (10), and a second coupling unit (58) disengagingly connects two rotatable components (28, 32, 51) at the second epicyclic gear (12), such that at least one of the rate of revolution and the torque at the first and the second main shafts (34, 36) can be influenced by controlling at least one of the first and the second coupling units (56, 58) to a condition of the rotatable components (22, 26, 50; 28, 32, 51) that is engaged or disengaged. Also a vehicle (1) having such a gearbox (2), a method to control such a gearbox (2), a computer program (P) to control a gearbox, and a computer program product comprising program code for an electronic control unit (48) or another computer (53) in order to implement the method.
