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 a known speed profile divided into a plurality of reference time intervals ( i ) with a constant speed or with a constant acceleration; comprising the steps of determining a driving torque (Ä OPT ) to be transmitted to the drive wheels, which allows the mean specific fuel consumption (BSFC) of the internal combustion engine (2) to be minimized as a function of the power (P i ), of the mechanical energy (E i ) requested in the reference time interval (A i ) and of the constant speed or acceleration (n i 1 ; n i 1 , n i 2 ) in the reference time interval ( i ); then determining the optimal distribution of the mechanical energy (E i ) so as to globally minimize the cumulative fuel consumption over the entire actuation profile; and controlling the reversible electrical machine (14) to deliver an additional driving torque (Ä ME ) as a function of the driving torque (Ä OPT ) to be transmitted to the drive wheels.
