Abstract

A gearbox having an input shaft () and an output shaft (); a first epicyclic gear () connected to the input shaft (); a second epicyclic gear () connected to the first epicyclic gear (); a first electrical machine () connected to the first epicyclic gear (); a second electrical machine () connected to the second epicyclic gear (); a first main shaft () connected to the first epicyclic gear (); a second main shaft () connected to the second epicyclic gear (). A first coupling unit () disengagingly connects two rotatable components () at the first epicyclic gear (), and a second coupling unit () disengagingly connects two rotatable components () at the second epicyclic gear (), such that at least one of the rate of revolution and the torque at the first and the second main shafts () can be influenced by controlling at least one of the first and the second coupling units () to a condition of the rotatable components () that is engaged or disengaged. Also a vehicle () having such a gearbox (), a method to control such a gearbox (), a computer program (P) to control a gearbox, and a computer program product comprising program code for an electronic control unit () or another computer () in order to implement the method.
