  "textContent": "Disclosed is a method for controlling a hybrid vehicle power train, including a thermal drive chain and an electric drive chain, the electric drive chain including a traction battery, a voltage modulator, an inverter, first and second electrical machines. The voltage modulator is designed to modulate a supply voltage of an electric current from the traction battery to the first and second electrical machines. The method includes: a step of analytically calculating an optimal supply voltage using a mathematical expression that corresponds to the resolution of an equation expressed as where Uis the supply voltage, Pis the electrical power supplied by the traction battery, and where the electrical power supplied by the traction battery is expressed as a quadratic function of the supply voltage; and a step of controlling the voltage modulator in such a way that it outputs the optimal supply voltage.",
