Abstract
An electronic control system for controlling automotive vehicle vision related equipment including an electrochromic rearview mirror comprising an electrochromic variable reflectance member the reflectivity of which varies as a function of electrical signal levels applied thereto, and an electrically energizable vehicle headlamp, the system including ambient light sensing means, glare causing light sensing means and sky light sensing means, each of said light sensing means being effective to generate an electrical signal indicative of the sensed light level, the system also including microprocessor means operable to apply electrical control signal levels to the electrochromic variable reflectance member to change the reflectivity thereof as a function of sensed ambient and glare causing light levels, the system also including means to effect energization of the vehicle headlamp as a function of the sensed sky light level. The system may also include means to effect energization of the vehicle headlamp as a function of the actuation of the vehicle windshield wiper.
