Abstract
A method for controlling a drive system of a vehicle. The drive system includes a combustion engine (2) with an output shaft (2a), a gearbox (3) with an input shaft (3a), an electrical machine (9) that comprises a stator (9a) and a rotor (9b), and a planetary gear that comprises a sun gear (10), a ring gear (11) and a planet wheel carrier (12). If the torque from the combustion engine and the electrical machine is sufficient for the operation of the vehicle with the planetary gear in the released state, and if the fuel consumption of the vehicle with the planetary gear in the released state is lower than in the locked states, then control the electrical machine and the combustion engine so that the requested torque is provided while the planetary gear is in the released state. Otherwise the planetary gear is arranged in the locked state and the method is terminated.
