The present invention relates to a method to control a hybrid powertrain, comprising a combustion engine, an electric machine, a gearbox with input shaft and output shaft, wherein the combustion engine and the electric machine are connected to the input shaft. The method comprises the following steps: a) disconnecting the combustion engine from the input shaft with a coupling device, b) engaging a starting gear in the gearbox, which starting gear is higher than the gear at which the combustion engine's torque at idling speed is able to operate the input shaft, c) generating a torque in the input shaft with the electric machine, d) accelerating the electric machine, and e) connecting the combustion engine to the input shaft with the coupling device when the electric machine has reached substantially the same rotational speed as the combustion engine. The invention also relates to a hybrid powertrain and a vehicle.
