Abstract
La présente invention se rapporte à un procédé de collecte et de contrôle d'un signal de pression de voie d'huile. Une unité centrale utilise un capteur de pression de voie pour mesurer un signal de pression de voie d'injection d'huile au moment de l'injection d'huile et un signal de pression de voie de pointe dans un intervalle prédéfini T, et commande la quantité d'huile injectée en fonction du signal de pression de voie d'injection d'huile ; l'unité centrale détermine également si le signal de pression de voie de pointe dépasse une plage prédéfinie, et contrôle la dérive dynamique du signal de pression de voie de pointe dans la phase de démarrage ; lorsque le signal de pression de voie de pointe dépasse la plage prédéfinie ou que la dérive dynamique du signal de pression de voie de pointe dépasse la valeur prédéfinie, l'unité centrale remplace le signal de pression de voie réelle par une valeur de pression de voie prédéfinie, ce qui permet de passer dans un mode dégradé. Le procédé peut mieux desservir un moteur, rendant le fonctionnement du moteur encore plus efficace.
