Title (EN) A METHOD AND AN APPARATUS FOR CONTROLLING AN ENGINE
(FR) PROCÉDÉ ET APPAREIL DE COMMANDE DE MOTEUR
Abstract:
(EN) A apparatus for controlling the output torque of an engine (13) in a drive train of a motor vehicle having a transmission (9) coupled to the engine and having a plurality of engeageable gear ratios comprises a control unit (16) for controlling the fuelling of the engine and a device (17) adapted to determine a maximum engine output torque not to be exceeded through the control of the control unit while considering torques resulting from such a control upon components of said driver train. The device is adapted to calculate a maximum limit transmission output torque from the so called slip torque of the vehicle, and the control unit is adapted to control the fuelling of the engine so as to delimit the engine output torque to a value resulting in a transmission output torque below said maximum limit transmission output torque.
(FR) La présente invention concerne un appareil destiné à commander le couple de sortie d’un moteur (13) dans un groupe motopropulseur d’un véhicule motorisé, qui comporte une transmission (9) couplée au moteur et qui possède une pluralité de rapports de transmission pouvant s’engrener, qui comprend une unité de commande (16) destinée à commander l’alimentation en carburant du moteur et un dispositif (17) conçu pour déterminer un couple moteur de sortie maximum qui ne doit pas être dépassé par l'intermédiaire de la commande de l’unité de commande tout en considérant des couples qui résultent d’une telle commande sur des composant dudit groupe motopropulseur. Le dispositif est conçu pour calculer un couple de sortie de transmission limite maximum à partir d’une limite de couple du véhicule, et l’unité de commande est conçue pour commander l’alimentation en carburant du moteur afin de limiter le couple moteur de sortie à une valeur qui a pour résultat un couple de sortie de transmission inférieur audit couple de sortie de transmission limite maximum.
