System for controlling active windows with glare sensor

Abstract

The present invention relates to a system for controlling the optical transmission of a plurality of windows Vk with electro-controllable optical transmission properties, comprising at least one spatial brightness sensor for supplying at least one value representative of brightness respectively for different spatial areas forming subsets Xi of a set X and thus supplying a mapping L of a brightness in which the subsets Li of L are associated with the sets Xi, and a control unit comprising a memory in which programs are stored which are capable of controlling the optical transmission of each of said windows. The programs are capable of defining a mapping A of spatial areas Aj of glare from the mapping L of brightness, of using a mapping O of spatial areas Om with electro-controllable brightness, each subset Om being associated with one or more of said windows Vk with electro-controllable optical transmission, and of controlling the optical transmission of each of said windows Vk with electro-controllable optical transmission as a function of A and of O.
