Abstract
A vehicular driving assist system includes an interior rearview mirror assembly having a mirror head adjustable about a mounting base. The mirror head accommodates an electrochromic mirror reflective element. An electrically dimmable window is disposed at the vehicle and is electrically operable to adjust visible light transmissivity of the electrically dimmable window. The vehicular driving assist system, based at least on processing sensor data captured by a light sensor, determines ambient light at the vehicle. The vehicular driving assist system, based at least on the determined ambient light, (i) adjusts light reflectivity of the electrochromic mirror reflective element and (ii) adjusts visible light transmissivity of the electrically dimmable window.
