Title
(DE) OBJEKT-ERKENNUNGSVORRICHTUNG FÜR KRAFTFAHRZEUGE
(EN) OBJECT-SENSING DEVICE FOR MOTOR VEHICLES
(FR) DISPOSITIF DE RECONNAISSANCE D'OBJETS POUR VEHICULES A MOTEUR
Abstract
(DE)
Bei einer Objekt-Erkennungsvorrichtung für Kraftfahrzeuge mit einem Sender-/Empfängerpaar (2, 3) für ein Infrarot-Reflexsignal, das durch ein in Fahrtrichtung liegendes Objekt (8) gebildet ist, sollen nur dann Objekte als kritisch eingestuft werden, wenn dies tatsächlich der Fall ist. Hierzu wird zwischen den Zuständen (I, II) klare und trübe Sicht unterschieden und im ersten Fall relativ selten, im zweiten Fall relativ häufig ein entsprechendes Warnsignal abgegeben. Umschaltung zwischen den beiden Zuständen wird automatisch von einem Nebelsensor oder manuell mit Hilfe eines Betriebszustandswählers (4) gemacht.
(EN)
An object-sensing device for motor vehicles comprising a sender/receiver pair (2, 3) for an infrared reflex signal produced by an object (8) located in the direction of motion of the vehicle classifies objects as critical only if this is actually the case. To this end, a distinction is made between the states (I, II) of clear and troubled vision and a corresponding warning signal is given, relatively rarely in the former case and relatively frequently in the latter case. Switching between the two states is effected either automatically by a fog sensor or manually with the aid of an operating mode selector (4).
(FR)
Un dispositif de reconnaissance d'objets pour véhicules à moteur comprend une paire d'émetteur/récepteur (2, 3) d'un signal infrarouge reflex formé par un objet (8) situé dans le sens de la marche. Seuls les objets présentant un danger sont considérés comme tels. A cet effet, une distinction est faite entre des états (I, II) de vue claire et de vue trouble. Dans le premier cas, il est relativement rare qu'un signal d'alarme soit déclenché, dans le deuxième cas des signaux d'alarme sont déclenchés avec une fréquence relativement élevée. La commutation entre les deux états se fait automatiquement au moyen d'un capteur de brouillard ou manuellement au moyen d'un sélecteur (4) du mode de fonctionnement.
