Abstract
(EN)
Control unit for controlling an engine torque (CM) making it possible to exit a freewheeling mode of operation of a motor vehicle provided with an acceleration member and with a braking member, the control unit being provided with an engine speed regulator configured to calculate an engine torque to be commanded in order to reach the target engine speed, this control unit being configured, as long as the target engine speed is not reached, to – compare the calculated engine torque against a predefined threshold level of engine torque associated with the degree to which the acceleration member is depressed and with the instantaneous engine speed of the vehicle; – command the engine torque level given by the minimum value between the threshold engine torque level and the calculated engine torque level.

(FR)
Unité de contrôle pour commander un couple moteur (CM) permettant de sortir d'un mode de fonctionnement en roue libre d'un véhicule automobile pour vu d'un organe d'accélération et d'un organe de freinage, l'unité de contrôle étant pour vue d'un régulateur de régime configuré pour calculer un couple moteur à commander pour atteindre le régime moteur cible, cette unité de contrôle étant configurée, tant que le régime moteur cible n'est pas atteint, pour - comparer le couple moteur calculé à un niveau seuil de couple moteur prédéfini associé au degré d'enfoncement de l'organe d'accélération et au régime moteur instantané du véhicule; - commander le niveau de couple moteur donné par la valeur minimale entre le niveau seuil de couple moteur et le niveau de couple moteur calculé.
