Method for computing a management setting regarding consumption of fuel and electric current by a hybrid motor vehicle comprising at least one electric motor supplied with electric current by a traction battery, and an internal combustion engine supplied with fuel, comprising steps of: a) acquiring, by means of a navigation system, a route to be taken, b) dividing said route into successive sections (T i, i∈{1...N}), c) acquiring, for each section (T i), attributes (FC, SC, SL, TS, RG, LL, NL, SMS, ZE) characterizing said section (T i), d) for each of said sections (T i) and taking into account its attributes (FC, SC, SL, TS, RG, LL, NL, SMS), acquiring a relationship (CE j) between the fuel consumption of the hybrid motor vehicle on the section (T i) and its consumption of electric energy (ΔSOE), e) determining an optimal consumption point (P i) in each of the acquired relationships (CE j), and f) generating an energy management setting along the route, depending on the coordinates of said optimal points (P i), in step c), a first of said acquired attributes relates to whether or not it is permitted to use the internal combustion engine on said section (T i), and in step e), provision is made to determine the optimal consumption points (P i) in such a way as to: - maximize the discharge of the traction battery on sections (T i) for which the first attribute indicates that it is not permitted to use the internal combustion engine, - minimize the fuel consumption of the hybrid motor vehicle over the route in its entirety, and - maximize the discharge of the traction battery by the end of the route, the method being characterized in that, in step e), provision is made to determine the optimal consumption points (P i) by penalizing points of the relationships (CE j) that correspond to a non-zero fuel consumption on the sections (T i) for which the first attribute indicates that it is not permitted to use the internal combustion engine, the optimal consumption points (P i) being determined by means of a heuristic optimization algorithm (A*) consisting in minimizing a function (f) that is the sum of a cost function (g) expressing the cost of reaching the section (T i) in question and of a heuristic function (h) expressing the remaining cost of getting from the section (T i) in question to the end of the route, so as to penalize the points of the relationships (CE j) that correspond to a non-zero fuel consumption on the sections (T i) for which the first attribute indicates that it is not permitted to use the internal combustion engine, the heuristic function (h) being computed differently on sections (T i) for which the first attribute indicates that it is not permitted to use the internal combustion engine than on the other sections (T i). a) acquiring, by means of a navigation system, a route to be taken, b) dividing said route into successive sections (T i, i∈{1...N}), c) acquiring, for each section (T i), attributes (FC, SC, SL, TS, RG, LL, NL, SMS, ZE) characterizing said section (T i), d) for each of said sections (T i) and taking into account its attributes (FC, SC, SL, TS, RG, LL, NL, SMS), acquiring a relationship (CE j) between the fuel consumption of the hybrid motor vehicle on the section (T i) and its consumption of electric energy (ΔSOE), e) determining an optimal consumption point (P i) in each of the acquired relationships (CE j), and f) generating an energy management setting along the route, depending on the coordinates of said optimal points (P i), in step c), a first of said acquired attributes relates to whether or not it is permitted to use the internal combustion engine on said section (T i), and in step e), provision is made to determine the optimal consumption points (P i) in such a way as to: -
