Individual mirror control system
First Claim
Patent Images
1. A vehicle rearview mirror control, comprising:
- a register comprising electronically encoded window tinting information;
a drive circuit mounted in an exterior rearview mirror housing and coupled to a mirror element, said drive circuit generates, selectively varies, and supplies the drive signal to said mirror element in response to a glare signal received by said drive circuit from a glare sensor, the glare signal representing a glare level, said drive circuit selectively varies the drive signal as a function of the glare level based upon a reflectance curve.

Abstract
A control system for a plurality of electrochromic elements, for example, used in automobiles, to control the glare of the IEC elements used as a rearview mirror (20) as well as the OEC elements (24, 26) used as sideview mirrors (24, 26). The drive circuits for the OEC'"'"'s elements may be customized to account for various factors such as the type of curvature as well as the size, vehicle glass characteristics, such as tinting, operating temperature and shape.
