  • the electronic device reaches the aim to operate in an effective way the control of vehicles' rear fog lights, in order to avoid the glare of the vehicle behind.
  • the device determines, in fact, the automatic switching off of the rear fog lights 6, 7 in the moment when the increase of luminous intensity detected by the electro-chromic mirror 2 signals the presence of a vehicle approaching from behind.
  • the increase of luminous intensity detected by the electro-chromic mirror 2 signals the presence of a vehicle approaching from behind.

  • a prerogative of the claimed invention consists in providing for, in order to detect the approaching of a vehicle from behind, the use of the inner rear- view mirror 2, of the so called electro-chromic type, already present in the vehicles of more modern conception.
  • a further advantage of the claimed invention is that it provides with an economic device, of simple installation and which does not require major changes in the structure and the original functional equipment of the vehicle.

Abstract

L'invention concerne un dispositif pour commander des feux antibrouillard arrière. Le dispositif comporte un rétroviseur (2) de type électrochromique permettant de détecter l'intensité de la lumière incidente et de produire un signal de commande de sortie approprié. Ce signal de commande est reçu par l'unité de commande électronique (4) relié au miroir électrochromique (2) par un circuit approprié. L'unité de commande électronique (4) produit un signal de commande de sortie approprié qui, par l'intermédiaire d'un autre circuit de transmission, est envoyé à un ou plusieurs relais présents dans une boîte à relais-fusibles (5) du véhicule afin d'actionner l'arrêt immédiat des feux antibrouillard arrière (6, 7) du véhicule.
