Method for calculating a control setpoint of a hybrid powertrain of a motor vehicle

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.
