Title
(EN) COLLISION AVOIDANCE SYSTEM FOR VEHICLES
(FR) SYSTEME DE PREVENTION DE COLLISIONS POUR VEHICULES
Abstract
(EN)
A collision avoidance system includes an object detection module (50) mounted on a vehicle (54) for detecting the presence of an object (68) within a monitored zone of space (56) adjacent the vehicle (54). The detection unit (50) emits a plurality of beams (66) of infrared energy and detects the reflection of such energy from objects (68) within the zone. The detection module (50) is typically activated by the host vehicle's electrical turn signal. The detection module (50) includes a plurality of associated pairs of light emitting diodes (134) and photosensitive detectors (128) for sensing the reflected light.
(FR)
Un système de prévention de collisions comprend un module (50) de détection d'objets monté sur un véhicule (54) pour détecter la présence d'un objet (68) dans une zone d'espace (56) contrôlée, adjacente audit véhicule (54). Ladite unité de détection (50) émet une pluralité de faisceaux (66) d'énergie infrarouge, et détecte la réflexion de ladite énergie provenant des objets (68) se trouvant dans ladite zone. Ledit module de détection (50) est en général activé par le signal électrique de changement de direction du véhicule hôte. Ledit module de détection (50) comprend une pluralité de paires associées de diodes électroluminescentes (134) et de détecteurs photosensibles (128) destinés à détecter la lumière réfléchie.
