Method for controlling a powertrain unit for a motor vehicle comprising an internal combustion engine (2), a main electrical machine (3) and an auxiliary electrical machine (4) connected to the internal combustion engine, the method comprising, in a series hybrid transmission mode where the main machine alone generates mechanical power for the wheels and where the internal combustion engine drives the auxiliary electrical machine functioning as a generator in order to produce charging power, steps of - controlling the engine speed at a set value, where the engine is torque-controlled on the basis of a torque value to be applied to the auxiliary machine, - detecting a situation in which the torque control of the auxiliary machine is saturated, and, - in the event of saturation, correcting the torque requested from the internal combustion engine such that the engine speed returns to its set value.
