Title
(EN) WARNING AND ADJUSTING THE LONGITUDINAL SPEED OF A MOTOR VEHICLE BASED ON THE RECOGNIZED ROAD TRAFFIC LIGHTS
(FR) AVERTISSEMENT ET RÉGLAGE DE LA VITESSE LONGITUDINALE D'UN VÉHICULE À MOTEUR SUR LA BASE DES FEUX DE SIGNALISATION RECONNUS
Abstract
(EN)
An automotive adaptive cruise control (ACC) system for a host motor vehicle (A) configured to operate in at least two different operating modes comprising a first operating mode, in which a current speed of the host vehicle (A) is controlled to maintain a cruise speed, and a second operating mode, in which the current speed of the host vehicle (A) is controlled to maintain a cruise distance to a leading vehicle, wherein the system is configured to: • detect approaching to a traffic light and determine a light signal emitted thereby, • signal to the driver the presence of the detected traffic light and the determined light signal, • if the traffic light emits a red or amber light signal, estimating a driver reaction time (TR), determining a higher threshold distance (SD1) and a lower threshold distance (SD2) from the traffic light, and warning the driver of the host vehicle (A) of the need to slow it down if, after the driver reaction time (TR) has elapsed: • the host vehicle (A) has not decreased its speed by more than a calibratable threshold, • the current speed of the host vehicle (A) is higher than a minimum speed, • either the distance of the host vehicle (A) from the traffic light is lower than the higher threshold distance (SD1) and the light signal emitted by the traffic light is red, or the distance of the host vehicle (A) from the traffic light is between the higher and lower threshold distances (SD1,SD2) and the light signal emitted by the traffic light is amber, and • a service brake of the host vehicle (A) is unoperated.
(FR)
L'invention concerne un système régulateur de vitesse et d'espacement (ACC) d'automobile pour véhicule à moteur hôte (A) étant conçu pour fonctionner dans au moins deux modes de fonctionnement différents comprenant un premier mode de fonctionnement, dans lequel une vitesse actuelle du véhicule hôte (A) est régulée pour maintenir une vitesse de croisière, et un second mode de fonctionnement, dans lequel la vitesse actuelle du véhicule hôte (A) est régulée pour maintenir une distance de croisière par rapport à un véhicule se trouvant à l'avant, le système étant conçu pour : • détecter l'approche d'un feu de signalisation et déterminer un signal lumineux émis par ledit feu, • signaler au conducteur la présence du feu de signalisation détecté et du signal lumineux déterminé, • si le feu de signalisation émet un signal lumineux rouge ou orange, estimer un temps de réaction du conducteur (TR), déterminer une distance seuil supérieure (SD1) et une distance seuil inférieure (SD2) jusqu'au feu de signalisation et avertir le conducteur du véhicule hôte (A) du besoin de ralentir si, après l'écoulement du temps de réaction du conducteur (TR) : • le véhicule hôte (A) n'a pas diminué sa vitesse par plus d'un seuil d'étalonnage, • la vitesse actuelle du véhicule hôte (A) est supérieure à une vitesse minimale, • ou si la distance du véhicule hôte (A) jusqu'au feu de signalisation est inférieure à la distance seuil supérieure (SD1) et le signal lumineux émis par le feu de signalisation est rouge, ou si la distance du véhicule hôte (A) jusqu'au feu de signalisation se trouve entre la distance seuil supérieure et inférieure (SD1, SD2) et si le signal lumineux émis par le feu de signalisation est orange, et • si un frein de service du véhicule hôte (A) n'est pas actionné.
