Title
(EN) SHIFT CONTROL DEVICE AND SHIFT CONTROL METHOD FOR AUTOMATIC TRANSMISSION
(FR) DISPOSITIF ET PROCÉDÉS DE COMMANDE DES VITESSES POUR BOÎTE DE VITESSES AUTOMATIQUE
Abstract
(EN)
An electronic control unit is provided with two types of gear change maps: a first gear change map based on the vehicle speed and the accelerator pedal operation amount; and a second gear change map based on the vehicle speed and the required drive force of the vehicle. The electronic control unit determines whether the automatic transmission should downshift with reference to the first gear change map, and determines whether the automatic transmission should upshift with reference to the second gear change map.
(FR)
L'invention concerne un bloc de commande électronique comportant deux types de cartes de changement de vitesse: une première carte de changement de vitesse basée sur la vitesse du véhicule et la valeur de commande de la pédale d'accélérateur; et une seconde carte de changement de vitesse basée sur la vitesse du véhicule et la force d'entraînement requise du véhicule. Le bloc de commande électronique détermine si la boîte de vitesses automatique doit rétrograder selon la première carte de changement de vitesse, et si la boîte de vitesses automatique doit passer à une vitesse supérieure selon la seconde carte de changement de vitesse.
