Vehicle rearview mirror system
First Claim
1. A rearview mirror system for a vehicle, said rearview mirror system comprising:
- an electro-optic reflective element;
an ambient light sensor that is operable to sense ambient light;
a glare light sensor that is operable to sense glare-producing light; and
a circuit that is responsive to said ambient and glare light sensors and which establishes a reflectance level of said reflective element, said circuit comprising a sensor-responsive device and a controller, said sensor-responsive device producing an output that is a function of light sensed by said glare and ambient light sensors, said controller connecting one of said glare and ambient light sensors at a time with said sensor-responsive device to establish glare and ambient light levels and thereby the reflectance level of said reflective element.

Abstract
A vehicle rearview mirror system includes an electro-optic reflective element, an ambient light sensor that is operable to sense ambient light, a glare light sensor that is operable to sense glare light and a circuit that is responsive to the ambient glare light sensors which establishes a reflectance level of the reflective element. The circuit includes a sensor-responsive device and a controller. The sensor-responsive device produces an output that is a function of light sensed by glare and ambient light sensors. The controller connects one of the glare and ambient light sensors at a time with the sensor-responsive device to establish glare and ambient light levels and thereby the reflectance level of the reflective element. The mirror system may include a display operable to project light through the reflective element and may control the intensity of the display as a function of the glare light and ambient light.
