Abstract

Abstract Translated from French Procédé de commande de modulation du couple d'un moteur thermique associé à une boîte de vitesses automatique, caractérisé en ce que le boîtier électronique de commande de la boîte de vitesses automatique agit sur un organe de commande dudit moteur au moyen d'une liaison unidirectionnelle et unifilaire, par un signal de modulation du couple qui est un signal tout ou rien modulé en durée, de manière à agir sur le couple moteur lors du passage des vitesses. Method for controlling the torque modulation of an internal combustion engine associated with an automatic gearbox, characterized in that the electronic control unit for the automatic gearbox acts on a control member of said engine by means of a one-way connection and single-line, by a torque modulation signal which is an all-or-nothing signal modulated in duration, so as to act on the engine torque when shifting gears.
