Abstract
A control system for one or more electrochromic elements used in an outside electrochromic (OEC) mirror used in automobiles or other vehicular applications, to control the glare of both IEC elements used as a rearview mirror () as well as the OEC elements () used as sideview mirrors (). An ambient light sensor () and glare sensor () operate to determine a glare level used to control both IEC and OEC electrochromic elements. The drive circuits for the OEC's elements may be controlled so as to account for various factors such as tinted glass characteristics in the vehicle.
