Abstract

A method for controlling a drive system of a vehicle, the drive system including a combustion engine with an output shaft, a gearbox with an input shaft, an electrical machine including a stator and a rotor, and a planetary gear with a sun gear, a ring gear and a planet wheel carrier. The combustion engine may be active or inactive. A braking device may be active or passive. The planetary gear may be released or locked. The method includes arranging the planetary gear in the released state, the combustion engine in inactive state, the braking device in active state, and, when information on a requested torque for the operation of the vehicle is received, controlling the electrical machine to provide the requested torque with the combustion engine inactive, the braking device active and the planetary gear released.
