Abstract

La présente invention a pour objet un procédé de détection de l'arrêt physique d'un moteur à combustion interne comprenant : • au moins quatre cylindres, • un ensemble de capteurs de pression de cylindre, configuré de sorte que tout au long d'un cycle de combustion du moteur, il existe au moins un cylindre en phase de compression ou de détente dont la pression est mesurée par un capteur de pression de l'ensemble, le procédé comprenant les étapes suivantes : • la mesure de la pression dans un cylindre en phase de compression ou de détente, • à partir de la pression mesurée dans le cylindre, le calcul d'un rapport entre une variation de pression dans le cylindre et la pression dans le cylindre, et • la détection d'un arrêt physique du moteur si la pression mesurée est décroissante et si le rapport calculé est constant.
