Abstract

L’invention concerne un procédé de régulation de vitesse d’un véhicule automobile, ou véhicule hôte, mettant en œuvre une fonction de régulation de vitesse adaptative (fonction ACC), le procédé comportant les étapes consistant à : - maintenir (30) la vitesse du véhicule hôte égale à une vitesse de consigne et maintenir le véhicule hôte à une distance d’un véhicule le précédant, ou véhicule cible, supérieure à une distance de consigne ; - diminuer (32) la vitesse du véhicule, jusqu’à l’arrêt du véhicule hôte si le ralentissement du véhicule cible l’impose ; - maintenir (34) le véhicule hôte à l’arrêt tant que les conditions ne permettent pas un redécollage ; - lorsqu’un redécollage requiert une action du conducteur sur la pédale d’accélérateur, inhiber (36) l’émission d’un message informant que la fonction ACC est suspendue pendant une durée prédéterminée ; - augmenter (38) la vitesse du véhicule hôte jusqu’à la vitesse de consigne. Figure pour l’abrégé : Fig. 2The invention relates to a method of regulating the speed of a motor vehicle, or host vehicle, implementing an adaptive speed regulation function (ACC function), the method comprising the steps of: - maintaining (30) the speed from the host vehicle equal to a setpoint speed and keep the host vehicle at a distance from a vehicle in front of it, or target vehicle, greater than a setpoint distance; - decrease (32) the speed of the vehicle, until the host vehicle stops if the slowing down of the target vehicle requires it; - keep (34) the host vehicle stationary as long as the conditions do not allow a relaunch; - when a relaunch requires action by the driver on the accelerator pedal, inhibit (36) the transmission of a message informing that the ACC function is suspended for a predetermined period; - increase (38) the speed of the host vehicle up to the set speed.
