1. A method for controlling a hybrid power plant for propelling a vehicle, the vehicle comprising:
a hybrid power plant provided with a single heat engine, a gearbox, a controller of the heat engine, at least one electrical unit and one power management unit, the at least one electrical unit comprising an electric machine, an electrical energy source, a control device of the electric machine electrically connected to the electric machine and to the electrical energy source, and sensors, the heat engine and the at least one electrical unit being mechanically connected respectively to input shafts of the gearbox; and
a movement device connected by a mechanical transmission system to an output shaft of the gearbox,
wherein the method comprises the following steps:
acquisition of at least one parameter of the at least one electrical unit by means of the sensors;
reception of a mechanical power requirement of the vehicle by the power management unit;
determination of usable electrical power that can be used by the at least one electrical unit, as a function of the at least one parameter and the mechanical power requirement of the vehicle;
establishment of at least one operating setpoint for the at least one electrical unit, by the power management unit, as a function of the usable electrical power, the at least one parameter and the mechanical power requirement; and
controlling of the heat engine and of the at least one electrical unit by means of the controller and the control device, respectively, as a function of the at least one operating setpoint, the at least one parameter and the mechanical power requirement.
