Abstract

La présente invention a pour objet un procédé de redémarrage d'un moteur thermique de véhicule automobile à vitesse non nulle. Plus précisément, lorsque le moteur thermique est mis à l'arrêt en roulage du véhicule, et qu'une requête de redémarrage est détectée, il comporte les étapes de la détermination du régime du moteur thermique (Rmth) et de la vitesse du véhicule (V) à l'instant de détection de la requête de redémarrage, lorsque ladite vitesse du véhicule est supérieure à un premier seuil prédéterminé de vitesse (S1) et lorsque ledit régime moteur est compris entre un deuxième seuil inférieur (S2) et un troisième seuil supérieur (S3), la commande automatique d'une transmission d'un couple moteur généré par au moins une roue du véhicule au vilebrequin du moteur thermique, et la régulation du régime du moteur thermique à un premier régime cible de déclenchement de la première combustion par ledit couple moteur transmis au vilebrequin.
