An engine stopping system for reducing electric consumption by interrupting power supply to a motor during disengagement of a clutch is provided. The engine stopping system is applied to a vehicle in which the clutch is interposed between an engine and a power distribution device. The engine stopping system is configured to interrupt power supply to the motor (step S7) while bringing the clutch into disengagement (step S4), when an input speed Nin falls below a threshold value α, under conditions that the engine does not generate power during engagement of the clutch, and that the motor generates electricity utilizing an inertia torque of the engine while controlling an output torque of the motor to lower the engine speed. La présente invention concerne un système d'arrêt de moteur pour réduire la consommation électrique en interrompant l'alimentation électrique d'un moteur pendant le débrayage d'un embrayage. Le système d'arrêt de moteur est appliqué à un véhicule dans lequel l'embrayage est intercalé entre un moteur et un dispositif de distribution d'énergie. Le système d'arrêt de moteur est configuré pour interrompre l'alimentation électrique du moteur (étape S7) tout en débrayant l'embrayage (étape S4), lorsqu'une vitesse d'entrée Nin diminue au-dessous d'une valeur de seuil α, à condition que le moteur ne génère pas de puissance pendant le débrayage de l'embrayage, et que le moteur génère de l'électricité en utilisant un couple d'inertie du moteur tout en contrôlant un couple de sortie du moteur pour diminuer la vitesse du moteur.
