A method for calculating a management setpoint for managing fuel and electric power consumption of a hybrid motor vehicle. The method includes: a) acquiring, via a navigation system, a journey to be made, b) dividing the journey into successive sections, c) acquiring, for each section, attributes characterizing the section, d) deducing a relation linking the estimated fuel consumption of the hybrid motor vehicle over the section to the estimated electric power consumption of the hybrid motor vehicle, e) measuring the actual fuel consumption and the actual electric power consumption of the motor vehicle, f) correcting the relation, taking into account the actual fuel and electric power consumptions, and g) determining an optimal consumption point in each of the corrected relations in order to minimize the fuel consumption of the motor vehicle over the journey as a whole.

A method that calculates a setpoint for managing the fuel and electricity consumption of a hybrid motor vehicle includes: a) acquiring, by a navigation system on board the hybrid motor vehicle, a route to be traveled; b) dividing the route into consecutive portions; c) assigning attributes that characterize each portion; d) determining, for each of the portions, a curve or a map that links each fuel consumption value of the hybrid motor vehicle over the portion to a charge or discharge value of the traction battery; e) determining an optimal point of each curve or map, which makes it possible to minimize the fuel consumption of the hybrid motor vehicle over the entire route and to completely discharge the traction battery by the end of the route; and f) producing an energy management setpoint in accordance with the coordinates of the optimal points.
