A method to control a hybrid vehicle with a parallel architecture and with a known speed profile divided into a plurality of reference time intervals with a constant speed or with a constant acceleration. The method includes the steps of determining a driving torque to be transmitted to the drive wheels, which allows the mean specific fuel consumption of the internal combustion engine to be minimized as a function of the power, of the mechanical energy requested in the reference time interval and of the constant speed or acceleration in the reference time interval; then determining the optimal distribution of the mechanical energy so as to globally minimize the cumulative fuel consumption over the entire actuation profile; and controlling the reversible electrical machine to deliver an additional driving torque as a function of the driving torque to be transmitted to the drive wheels.

Method to control a hybrid vehicle with a parallel architecture and with a known speed profile for the optimization of the fuel consumption

A method to control a hybrid vehicle with a parallel architecture and with an unknown speed profile, wherein the hybrid vehicle is provided with an internal combustion engine and with a reversible electrical machine connected to a storage system designed to store electrical energy; the method comprises the steps of recognizing the operating mode of the hybrid vehicle; determining a function of the specific fuel consumption of the drive system of the hybrid vehicle as a function of the operating mode of the hybrid vehicle; determining the optimal value of the power of the storage system and the optimal value of the power of the internal combustion engine, which correspond to the values that permit a minimization of said function.
