Abstract
In a method for controlling a vehicle with a drive system comprising an output shaft in a combustion engine, a planetary gear and a first and second electrical machine connected to the planetary gear, the turning off of the combustion engine is achieved when the vehicle is driven with the combustion engine running, and a transition to operation of the vehicle with the electrical machines is achieved by ensuring that the second electrical machine's rotor is connected with the combustion engine's output shaft, that injection of fuel into the combustion engine is interrupted and that the second electrical machines rotational speed is controlled towards and until a standstill, whereupon the combustion engine's output shaft is disconnected from the second electrical machine and the planetary gear.
