description A variable transmittance vehicle window may adjust its transmittance in response to readings from an interior light sensor that is positioned to measure intensity of at least one wavelength of light that is a proper subset of the visible spectrum and that has entered the interior of a vehicle comprising the window after passing through the window. If the intensity of light inside the vehicle is too high, the window is darkened; analogously, if the intensity of light inside the vehicle is too low, the window is lightened. Additionally or alternatively, the window may be transitioned to and maintained at an intermediate transmittance that is between the window's maximum and minimum transmittances. L'invention concerne une fenêtre de véhicule à transmittance variable capable de régler sa transmittance en réaction à des indications provenant d'un capteur de lumière intérieure qui est positionné de façon à mesurer l'intensité d'au moins une longueur d'onde de lumière qui est une partie propre du spectre visible et qui a pénétré à l'intérieur d'un véhicule comportant la fenêtre après avoir traversé la fenêtre. Si l'intensité de lumière à l'intérieur du véhicule est trop élevée, la fenêtre est assombrie; de manière analogue, si l'intensité de lumière à l'intérieur du véhicule est trop faible, la fenêtre est éclaircie. En outre ou en variante, la fenêtre peut être amenée et maintenue à une transmittance intermédiaire qui se situe entre les transmittances maximale et minimale de la fenêtre.
