Abstract
A sensor of a brightness limiting system of a vehicle may sense light from light sources around the vehicle and provide a light measurement signal. The light measurement signal may include information about brightness levels and positions of light sources relative to a window of the vehicle. A brightness controller may monitor the light source measurement signal and perform comparisons of brightness levels from the light measurement signal with brightness thresholds. The brightness controller may determine that a brightness level of a light source exceeds a brightness threshold and may provide a brightness control signal to a brightness control layer positioned adjacent to the window of the vehicle. The brightness control layer may receive the brightness control signal and limit the brightness level of light based on the brightness threshold at a brightness control area of the brightness control layer.
