A method of controlling a vehicle associated micro-hybrid system. The system includes a reversible rotary electrical machine that is connected to a thermal engine of a motor vehicle. The method includes: controlling a step of pre-fluxing of a rotor of the reversible rotary electrical machine when a control module receives an instruction to start the thermal engine via the reversible rotary electrical machine; measuring a speed of the rotor of the reversible rotary electrical machine; and, demanding stoppage of the pre-fluxing step when the speed of the rotor is greater than or equal to a predetermined speed threshold value. The method avoids the generation of overvoltages in an electrical distribution network formed by an onboard network of the vehicle and by an energy storage unit of the micro-hybrid system.
A control module (4) of a micro-hybrid system (1), comprising a reversible rotary electrical machine (2) connected to a thermal engine (9) of a motor vehicle, the control module comprising:
