A method for generating a torque setpoint for the electric machines (ME, HSG) of a powertrain (GMP) of a vehicle, comprising at least one gearbox with controlled dog clutches, a main electric machine (ME) capable of transmitting torque to the wheels of the vehicle over two separate gearbox ratios, and a secondary electric machine (HSG) capable of providing compensation torque to the wheel during ratio changes of the main machine, in which the maximum and minimum torques imposed on the two electric machines in the established ratio are calculated depending on the predicted future state of a shared power supply battery, characterised in that, in anticipation of a change of ratio of the main machine (ME), a new limit is imposed in advance on the torques of the two electric machines, stricter than that of the established ratio, in order to ensure, without discontinuity during the change in ratio, the synchronisation of the main machine (ME) in the new ratio and the torque compensation by the secondary machine (HSG).
