Patent attributes
A vehicular rearview mirror control system includes a rearview mirror assembly having a variable reflectance electro-optic mirror reflective element. An electronic control unit receives image data captured by a rear backup camera of the vehicle. The electronic control unit, responsive to processing a first subset of received image data captured by the rear backup camera, determines ambient light rearward of the equipped vehicle. The electronic control unit, responsive to processing a second subset of received image data captured by the rear backup camera, determines glare light emanating from a headlight of another vehicle following the equipped vehicle. The first subset of received image data is different than the second subset of received image data. The electronic control unit generates an output to control dimming of the mirror reflective element of the rearview mirror assembly responsive to a determined location of the determined glare light.
