Abstract: Disclosed is a method for calculating a control setpoint of a hybrid powertrain of a motor vehicle, the hybrid powertrain including an electric motor and an internal combustion engine (ICE) that is equipped with a gearbox and that is supplied with fuel. The method includes: acquiring a value relative to a power requested at the vehicle's drive wheels; and determining the contribution of the electric motor and the ICE in order to satisfy the request for power at the drive wheels. The determination step involves calculating a triplet of three values, one value relating to the electromechanical power that the electric motor must provide, one value relating to the thermomechanical power that the ICE must provide and one value relating to the ratio that needs to be engaged in the gearbox, this triplet minimising the fuel consumption of the ICE and the current consumption of the electric motor.

Abstract: 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 Ue is the supply voltage, Pbat is 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.

Abstract: A method of determining an equivalence energy factor representing weighting applied between an infeed of energy of thermal origin and an infeed of energy of electrical origin, to minimize on an operating point overall energy consumption of a hybrid motor propulsion plant for an automotive vehicle including a heat engine and at least one electric motor powered by a battery. This factor is controlled in a discrete manner as a function of an instantaneous state of energy of the battery, and of an energy target, and as a function of the vehicle running conditions.

Abstract: A method manages energy of a power unit of a hybrid vehicle. The power unit includes at least one internal combustion engine and an electric drive machine, coupled to wheels of the vehicle by a transmission with discrete ratios. The method includes minimizing, at each operating point of the energy, an energy criterion linked to a sum of consumption of the internal combustion engine and an electrical consumption of the electrical machine multiplied by an equivalence factor weighting a supply of energy from the internal combustion engine and a supply of energy of electrical origin. The minimized criterion is a mixed criterion which is a sum of an energy criterion and a discomfort criterion linked to management of kinematic modes of the transmission.
