Title (EN) DYNAMIC TORQUE MANAGEMENT TECHNIQUES FOR ENHANCED ENGINE CYCLE EFFICIENCY
(FR) TECHNIQUES DE GESTION DE COUPLE DYNAMIQUE POUR UNE EFFICACITÉ DE CYCLE DU MOTEUR AMÉLIORÉE
Abstract:
(EN) One embodiment is a method of operating an electronic control system (ECS) to control an engine to propel a vehicle. The method comprises receiving a throttle command, determining an operation to increase engine cycle efficiency by reducing engine torque below a magnitude corresponding to the throttle command and below a torque curve limit over a first vehicle operation segment and permitting an increase in engine torque above the torque curve limit over a second vehicle operation segment, controlling the engine to output torque below the magnitude corresponding to the throttle command and below the torque curve limit over the first vehicle operation segment, and controlling the engine to output torque above the torque curve limit over the second vehicle operation segment in response to a second received throttle command and constrained by an extended limit on operation of the engine above the torque curve limit.
(FR) L'invention concerne, dans un mode de réalisation, un procédé de fonctionnement d'un système de commande électronique (ECS) pour commander un moteur pour propulser un véhicule. Le procédé consiste à recevoir une instruction de papillon des gaz, à déterminer une opération pour augmenter l'efficacité de cycle du moteur en réduisant le couple du moteur au-dessous d'une amplitude correspondant à l'instruction de papillon des gaz et au-dessous d'une limite de courbe de couple sur un premier segment de fonctionnement de véhicule et permettant une augmentation du couple du moteur au-dessus de la limite de courbe de couple sur un second segment de fonctionnement de véhicule, commander le moteur pour délivrer un couple au-dessous de l'amplitude correspondant à l'instruction de papillon des gaz et au-dessous de la limite de courbe de couple sur le premier segment de fonctionnement de véhicule et commander le moteur pour délivrer un couple au-dessus de la limite de courbe de couple sur le second segment de fonctionnement de véhicule en réponse à une seconde instruction de papillon des gaz reçue et contraint par une limite étendue lors du fonctionnement du moteur au-dessus de la limite de courbe de couple.
