The invention concerns a gearbox comprising an input shaft (8) and an output shaft (20); a first epicyclic gear (10) that is connected to the input shaft (8); a second epicyclic gear (12) that is connected to the first epicyclic gear (10); a first electrical machine (14) that is connected to the first epicyclic gear (10); a second electrical machine (16) that is connected to the second epicyclic gear (12); a first main shaft (34) that is connected to the first epicyclic gear (10); a second main shaft (36) that is connected to the second epicyclic gear (12). A first coupling unit (56) that can be controlled is arranged to connect in a manner that allows them to be disengaged two rotatable components (22, 26, 50) at the first epicyclic gear (10), and a second coupling unit (58) that can be controlled is arranged to connect in a manner that allows them to be disengaged 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. The invention concerns also a vehicle (1) that comprises such a gearbox (2), and a method to control such a gearbox (2). The invention concerns also 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 according to the invention.
