Title (EN) ENGINE SPEED CONTROL FOR IMPROVED SHIFTING
(FR) REGULATION DU REGIME MOTEUR AMELIORANT LE PASSAGE DES RAPPORTS
Abstract: front page image
(EN)A vehicle includes a powershift transmission (12) driven by an electronically controlled engine (10). A control system momentarily modifies a magnitude of an engine speed command signal SC during a shift of the power shift transmission (12) in order to make the shift smoother and less sensitive to achieving optimum clutch engagement pressure. It also prevents an engine governor from over-reacting and causing rough shifts.
(FR)L'invention porte sur un véhicule muni d'une transmission automatique (12) commandée par la régulation électronique du moteur (10). Le système de régulation modifie momentanément la grandeur du signal (SC) de commande du régime du moteur lors des passages des rapports de la transmission (12) pour les rendre plus doux et moins sensibles et arriver à la pression d'embrayage optimale, tout en évitant les sur-réactions du régulateur de régime et les à-coups.
