1. A method for managing the “
- stop-and-start”
mode in a motor vehicle equipped with an internal combustion engine;
the method comprises the phases of;
determining a state of charge (SOC) of a battery of the motor vehicle;
determining a state of motion of a crankshaft of the internal combustion engine by selecting one of the following alternatives;
the crankshaft is stationary, the crankshaft is in the starting phase, the crankshaft is in rotation but is not capable of being self-sustaining, the crankshaft is in rotation and capable of being self-sustaining, and the crankshaft is in the stopping phase;
determining the electric power consumed overall by the electrical consumers of the motor vehicle; and
enabling or disabling the “
stop-and-start”
mode as a function of the state of charge (SOC) of the main battery, as a function of the state of motion of the crankshaft of the engine, and as a function of the electric power consumed overall by the electrical consumers of the motor vehicle.
