Title (EN) A TRANSMISSION CONTROL SYSTEM FOR A VEHICLE
(FR) SYSTEME DE COMMANDE DE TRANSMISSION POUR VEHICULE
Abstract:
(EN) A CVT controller (22) of a vehicle (10) communicates with the engine management system (EMS) (20). When a manual shift between simulated fixed ratios is performed, the CVT controller (22) sends a shift signal to the EMS (20) which alters the engine torque for the duration of the shift in order to simulate a manual shift to provide, for example, a sporty feel to the vehicle (10).
(FR) L'invention concerne un organe de commande de transmission à changement de vitesses continu (22) d'un véhicule (10), cet organe de commande communiquant avec le système de gestion du moteur (EMS) (20). Lorsqu'on effectue un changement manuel entre des rapports fixes simulés, l'organe de commande de transmission à changement de vitesses continu (22) envoie un signal de changement à l'EMS (20) qui modifie le couple moteur pendant la durée du changement afin de simuler un changement manuel, de manière à donner, par exemple, une allure sportive au véhicule (10).
