Automotive electrical system provided with an alternator electronic control system

Automotive electrical system (1) for a motor vehicle (3) comprising an internal combustion engine (2) of a motor vehicle (3);

• the automotive electrical system (1) comprising a number of electric vehicle loads (8), an electric battery (6), and an alternator (4) operable by the internal combustion engine (2) for generating a supply voltage (Vsup) adapted to be supplied to the electric vehicle loads (8) and to the electric battery (6);
• the alternator (4) comprising an inductive electric circuit adapted to be crossed, in use, by an electric control current (Ireg) adapted to regulate the supply voltage (Vsup);
• said automotive electrical system (1) comprising an alternator electronic control system (9) configured to vary said control current (Ireg) so as to regulate said supply voltage (Vsup);
• said alternator electronic control system (9) is further configured to:
• determine a series of battery parameters (pam_bat) indicating the operating state of the electric battery (6);
• determine at least one first vehicle parameter (Acc) indicating the acceleration of the motor vehicle (3);
• determine the operative state of the internal combustion engine (2);
• determine an electric regulation voltage (Vreg) according to said operative state of the engine, to the vehicle parameter (Acc) and to said battery parameters (pam_bat);
• vary the electric control current (Ireg) circulating, in use, in the inductive electric circuit of the alternator (4) according to said electric regulation voltage (Vreg);
• said automotive electrical system (1) being characterized in that said alternator electronic control system (9) is configured to implement a first regulation procedure to reduce said electric regulation voltage (Vreg) when a first condition is determined, wherein:
• the operative state of the internal combustion engine corresponds to an engine running state (SYSTEM RUNNING);
• a battery parameter (pam_bat) indicating the battery state of charge (SOCmeas) is either higher than or equal to a predetermined charge threshold (SOClim);
• and
• said first vehicle parameter (Acc) indicating the acceleration of the motor vehicle (3) is either higher than or equal to a first predetermined acceleration threshold (ACClim).
