This method for controlling a power train (1) of a motor vehicle comprises a first phase (P1) of switching the torque from the second primary shaft to the first primary shaft, a second phase (P2) of disengaging an input electric transmission ratio, a third phase (P3) of synchronising the speed of rotation (ωmep) of the main electric machine, a fourth phase (P4) of engaging an output electric transmission ratio, and a fifth phase (P5) of switching the torque from the first primary shaft to the second primary shaft. The first phase comprises a first step (E03) of calculating a target power value (Pice_cible_e03) and a second step (E04) of increasing the power (Pice) delivered by the internal combustion engine to the target value, the target value being determined such that, at the end of the second step, the power (Pmep) delivered by the main electric machine can be completely compensated for by an increase in the power (Phsg) delivered by the secondary electric machine.
