A method for controlling a hybrid drive system for a road vehicle provided with at least a pair of drive wheels; the hybrid drive system comprises: an internal combustion heat engine, which is designed to transmit the motion to the drive wheels and is provided with a turbocharger equipped with a turbine; a first electric machine, which is able to transmit the motion to the drive wheels; and a second electric machine, which is mechanically connected to the turbine of the turbocharger. In a possible operating mode, the internal combustion heat engine is controlled to pursue a target torque by completely opening a throttle valve, operating the second electric machine as an electric generator and the first electric machine as a motor, and varying the electric power generated by the second electric machine so as to adjust the flow rate of fresh air fed to the cylinder of the internal combustion heat engine.
