Abstract

L'invention concerne des procédés permettant de commander un moteur sans cames afin d'empêcher des interférences entre les soupapes et les pistons dudit moteur. Les procédés utilisent au moins une trajectoire sécurisée des soupapes par rapport à un angle de vilebrequin. En fonctionnement normal, le système de commande des soupapes du moteur surveille l'angle du vilebrequin et commande la soupape du moteur de façon à rester sur le côté sécurisé d'une trajectoire sécurisée. Si le mouvement effectif de la soupape dévie de manière excessive de la trajectoire escomptée pour atteindre ou traverser la trajectoire sécurisée, une mesure préventive est prise, à savoir on commande la fermeture de la soupape du moteur. Les trajectoires sécurisées peuvent être stockées dans de tables de consultation et/ou sous forme d'équations. Dans certains cas, une seule trajectoire sécurisée pour une soupape peut suffire, bien que, dans d'autres cas, des trajectoires sécurisées en fonction de certains états de fonctionnement et environnementales du moteur, et dans quelques cas peuvent comporter une accélération du vilebrequin. L'invention concerne divers modes de réalisation.
