Beschreibung
Zusammenfassung:	The subject of the invention is a method for controlling an alternator (30) for a hybrid vehicle equipped with a combustion engine (2) driving a transmission (6) via a progressive-coupling member (4), this vehicle comprising an electric traction machine (10; 18) powered by a traction battery (12), which delivers torque to the driven wheels (8, 26) without passing via the coupling member (4), and comprising a voltage converter (36) recharging a battery of the on-board network (34), this method being notable in that if the battery of the on-board network (34) needs recharging, it allows the alternator (30) to take torque off the combustion engine (2) when the speed of the vehicle is below a speed threshold, and it prevents this taking-off of torque if the speed is above this threshold and if the coupling member (4) is fully closed.
