Abstract

L’invention propose un procédé de commande d’un système anti-éblouissement pour véhicules automobiles, qui implique un dispositif actif à opacité/transparence sélective, commandé par un signal périodique. Le procédé et le système proposés permettent de réduire fortement un phénomène de scintillement lié à la fréquence de pulsation d’une lumière incidente, qui a été observé pour de tels systèmes existants. (Fig. 1)
