Un dispositif d'arrêt/démarrage automatique du moteur comprend : un démarreur (14) ; une couronne dentée (12) ; un élément (17) de déplacement d'un pignon ; et un moyen (11) de commande du démarreur qui sert, pendant que le moteur tourne par inertie lorsqu'une condition d'arrêt automatique est satisfaite, à exécuter une commande d'engagement sur la base du nombre de tours du moteur, et à exécuter une commande de redémarrage du moteur pour redémarrer le moteur lorsqu'une condition de redémarrage est satisfaite. Dans la commande d'engagement exécutée par le moyen de commande du démarreur, l'application du courant au moyen de déplacement du pignon est interrompue au moins simultanément au moment ou avant que la rotation du moteur s'arrête.
